[X86] Reduce the width of multiplification when its operands are extended from i8 or i16 For <N x i32> type mul, pmuludq will be used for targets without SSE41, which often introduces many extra pack and unpack instructions in vectorized loop body because pmuludq generates <N/2 x i64> type value. However when the operands of <N x i32> mul are extended from smaller size values like i8 and i16, the type of mul may be shrunk to use pmullw + pmulhw/pmulhuw instead of pmuludq, which generates better code. For targets with SSE41, pmulld is supported so no shrinking is needed. Differential Revision: http://reviews.llvm.org/D20931 llvm-svn: 272694

Correct dwarf unwind information in function epilogue This patch aims to provide correct dwarf unwind information in function epilogue for X86. It consists of two parts. The first part inserts CFI instructions that set appropriate cfa offset and cfa register in emitEpilogue() in X86FrameLowering. This part is X86 specific. The second part is platform independent and ensures that: * CFI instructions do not affect code generation (they are not counted as instructions when tail duplicating or tail merging) * Unwind information remains correct when a function is modified by different passes. This is done in a late pass by analyzing information about cfa offset and cfa register in BBs and inserting additional CFI directives where necessary. Added CFIInstrInserter pass: * analyzes each basic block to determine cfa offset and register are valid at its entry and exit * verifies that outgoing cfa offset and register of predecessor blocks match incoming values of their successors * inserts additional CFI directives at basic block beginning to correct the rule for calculating CFA Having CFI instructions in function epilogue can cause incorrect CFA calculation rule for some basic blocks. This can happen if, due to basic block reordering, or the existence of multiple epilogue blocks, some of the blocks have wrong cfa offset and register values set by the epilogue block above them. CFIInstrInserter is currently run only on X86, but can be used by any target that implements support for adding CFI instructions in epilogue. Patch by Violeta Vukobrat.

[X86][SSE] Aggressively use PMADDWD for v4i32 multiplies with 17 or more leading zeros As discussed in D41484, PMADDWD for 'zero extended' vXi32 is nearly always a better option than PMULLD: On SNB it will result in code that isn't any faster, but not any slower so we may as well keep it. On KNL it only has half the throughput, so I've disabled it on there - ideally there'd be a better way than this. Differential Revision: https://reviews.llvm.org/D42258 llvm-svn: 323367

[X86] Reduce the width of multiplification when its operands are extended from i8 or i16 For <N x i32> type mul, pmuludq will be used for targets without SSE41, which often introduces many extra pack and unpack instructions in vectorized loop body because pmuludq generates <N/2 x i64> type value. However when the operands of <N x i32> mul are extended from smaller size values like i8 and i16, the type of mul may be shrunk to use pmullw + pmulhw/pmulhuw instead of pmuludq, which generates better code. For targets with SSE41, pmulld is supported so no shrinking is needed. Differential Revision: http://reviews.llvm.org/D20931 llvm-svn: 272694

Correct dwarf unwind information in function epilogue This patch aims to provide correct dwarf unwind information in function epilogue for X86. It consists of two parts. The first part inserts CFI instructions that set appropriate cfa offset and cfa register in emitEpilogue() in X86FrameLowering. This part is X86 specific. The second part is platform independent and ensures that: * CFI instructions do not affect code generation (they are not counted as instructions when tail duplicating or tail merging) * Unwind information remains correct when a function is modified by different passes. This is done in a late pass by analyzing information about cfa offset and cfa register in BBs and inserting additional CFI directives where necessary. Added CFIInstrInserter pass: * analyzes each basic block to determine cfa offset and register are valid at its entry and exit * verifies that outgoing cfa offset and register of predecessor blocks match incoming values of their successors * inserts additional CFI directives at basic block beginning to correct the rule for calculating CFA Having CFI instructions in function epilogue can cause incorrect CFA calculation rule for some basic blocks. This can happen if, due to basic block reordering, or the existence of multiple epilogue blocks, some of the blocks have wrong cfa offset and register values set by the epilogue block above them. CFIInstrInserter is currently run only on X86, but can be used by any target that implements support for adding CFI instructions in epilogue. Patch by Violeta Vukobrat.

Correct dwarf unwind information in function epilogue This patch aims to provide correct dwarf unwind information in function epilogue for X86. It consists of two parts. The first part inserts CFI instructions that set appropriate cfa offset and cfa register in emitEpilogue() in X86FrameLowering. This part is X86 specific. The second part is platform independent and ensures that: * CFI instructions do not affect code generation (they are not counted as instructions when tail duplicating or tail merging) * Unwind information remains correct when a function is modified by different passes. This is done in a late pass by analyzing information about cfa offset and cfa register in BBs and inserting additional CFI directives where necessary. Added CFIInstrInserter pass: * analyzes each basic block to determine cfa offset and register are valid at its entry and exit * verifies that outgoing cfa offset and register of predecessor blocks match incoming values of their successors * inserts additional CFI directives at basic block beginning to correct the rule for calculating CFA Having CFI instructions in function epilogue can cause incorrect CFA calculation rule for some basic blocks. This can happen if, due to basic block reordering, or the existence of multiple epilogue blocks, some of the blocks have wrong cfa offset and register values set by the epilogue block above them. CFIInstrInserter is currently run only on X86, but can be used by any target that implements support for adding CFI instructions in epilogue. Patch by Violeta Vukobrat.

[X86][SSE] Aggressively use PMADDWD for v4i32 multiplies with 17 or more leading zeros As discussed in D41484, PMADDWD for 'zero extended' vXi32 is nearly always a better option than PMULLD: On SNB it will result in code that isn't any faster, but not any slower so we may as well keep it. On KNL it only has half the throughput, so I've disabled it on there - ideally there'd be a better way than this. Differential Revision: https://reviews.llvm.org/D42258 llvm-svn: 323367

[X86][SSE] Aggressively use PMADDWD for v4i32 multiplies with 17 or more leading zeros As discussed in D41484, PMADDWD for 'zero extended' vXi32 is nearly always a better option than PMULLD: On SNB it will result in code that isn't any faster, but not any slower so we may as well keep it.

[X86] Reduce the width of multiplification when its operands are extended from i8 or i16 For <N x i32> type mul, pmuludq will be used for targets without SSE41, which often introduces many extra pack and unpack instructions in vectorized loop body because pmuludq generates <N/2 x i64> type value. However when the operands of <N x i32> mul are extended from smaller size values like i8 and i16, the type of mul may be shrunk to use pmullw + pmulhw/pmulhuw instead of pmuludq, which generates better code. For targets with SSE41, pmulld is supported so no shrinking is needed. Differential Revision: http://reviews.llvm.org/D20931 llvm-svn: 272694

Correct dwarf unwind information in function epilogue This patch aims to provide correct dwarf unwind information in function epilogue for X86. It consists of two parts. The first part inserts CFI instructions that set appropriate cfa offset and cfa register in emitEpilogue() in X86FrameLowering. This part is X86 specific. The second part is platform independent and ensures that: * CFI instructions do not affect code generation (they are not counted as instructions when tail duplicating or tail merging) * Unwind information remains correct when a function is modified by different passes. This is done in a late pass by analyzing information about cfa offset and cfa register in BBs and inserting additional CFI directives where necessary. Added CFIInstrInserter pass: * analyzes each basic block to determine cfa offset and register are valid at its entry and exit * verifies that outgoing cfa offset and register of predecessor blocks match incoming values of their successors * inserts additional CFI directives at basic block beginning to correct the rule for calculating CFA Having CFI instructions in function epilogue can cause incorrect CFA calculation rule for some basic blocks. This can happen if, due to basic block reordering, or the existence of multiple epilogue blocks, some of the blocks have wrong cfa offset and register values set by the epilogue block above them. CFIInstrInserter is currently run only on X86, but can be used by any target that implements support for adding CFI instructions in epilogue. Patch by Violeta Vukobrat.

Correct dwarf unwind information in function epilogue This patch aims to provide correct dwarf unwind information in function epilogue for X86. It consists of two parts. The first part inserts CFI instructions that set appropriate cfa offset and cfa register in emitEpilogue() in X86FrameLowering. This part is X86 specific. The second part is platform independent and ensures that: * CFI instructions do not affect code generation (they are not counted as instructions when tail duplicating or tail merging) * Unwind information remains correct when a function is modified by different passes. This is done in a late pass by analyzing information about cfa offset and cfa register in BBs and inserting additional CFI directives where necessary. Added CFIInstrInserter pass: * analyzes each basic block to determine cfa offset and register are valid at its entry and exit * verifies that outgoing cfa offset and register of predecessor blocks match incoming values of their successors * inserts additional CFI directives at basic block beginning to correct the rule for calculating CFA Having CFI instructions in function epilogue can cause incorrect CFA calculation rule for some basic blocks. This can happen if, due to basic block reordering, or the existence of multiple epilogue blocks, some of the blocks have wrong cfa offset and register values set by the epilogue block above them. CFIInstrInserter is currently run only on X86, but can be used by any target that implements support for adding CFI instructions in epilogue. Patch by Violeta Vukobrat.

[X86] Reduce the width of multiplification when its operands are extended from i8 or i16 For <N x i32> type mul, pmuludq will be used for targets without SSE41, which often introduces many extra pack and unpack instructions in vectorized loop body because pmuludq generates <N/2 x i64> type value. However when the operands of <N x i32> mul are extended from smaller size values like i8 and i16, the type of mul may be shrunk to use pmullw + pmulhw/pmulhuw instead of pmuludq, which generates better code. For targets with SSE41, pmulld is supported so no shrinking is needed. Differential Revision: http://reviews.llvm.org/D20931 llvm-svn: 272694

Correct dwarf unwind information in function epilogue This patch aims to provide correct dwarf unwind information in function epilogue for X86. It consists of two parts. The first part inserts CFI instructions that set appropriate cfa offset and cfa register in emitEpilogue() in X86FrameLowering. This part is X86 specific. The second part is platform independent and ensures that: * CFI instructions do not affect code generation (they are not counted as instructions when tail duplicating or tail merging) * Unwind information remains correct when a function is modified by different passes. This is done in a late pass by analyzing information about cfa offset and cfa register in BBs and inserting additional CFI directives where necessary. Added CFIInstrInserter pass: * analyzes each basic block to determine cfa offset and register are valid at its entry and exit * verifies that outgoing cfa offset and register of predecessor blocks match incoming values of their successors * inserts additional CFI directives at basic block beginning to correct the rule for calculating CFA Having CFI instructions in function epilogue can cause incorrect CFA calculation rule for some basic blocks. This can happen if, due to basic block reordering, or the existence of multiple epilogue blocks, some of the blocks have wrong cfa offset and register values set by the epilogue block above them. CFIInstrInserter is currently run only on X86, but can be used by any target that implements support for adding CFI instructions in epilogue. Patch by Violeta Vukobrat.

[X86] Reduce the width of multiplification when its operands are extended from i8 or i16 For <N x i32> type mul, pmuludq will be used for targets without SSE41, which often introduces many extra pack and unpack instructions in vectorized loop body because pmuludq generates <N/2 x i64> type value. However when the operands of <N x i32> mul are extended from smaller size values like i8 and i16, the type of mul may be shrunk to use pmullw + pmulhw/pmulhuw instead of pmuludq, which generates better code. For targets with SSE41, pmulld is supported so no shrinking is needed. Differential Revision: http://reviews.llvm.org/D20931 llvm-svn: 272694

Correct dwarf unwind information in function epilogue This patch aims to provide correct dwarf unwind information in function epilogue for X86. It consists of two parts. The first part inserts CFI instructions that set appropriate cfa offset and cfa register in emitEpilogue() in X86FrameLowering. This part is X86 specific. The second part is platform independent and ensures that: * CFI instructions do not affect code generation (they are not counted as instructions when tail duplicating or tail merging) * Unwind information remains correct when a function is modified by different passes. This is done in a late pass by analyzing information about cfa offset and cfa register in BBs and inserting additional CFI directives where necessary. Added CFIInstrInserter pass: * analyzes each basic block to determine cfa offset and register are valid at its entry and exit * verifies that outgoing cfa offset and register of predecessor blocks match incoming values of their successors * inserts additional CFI directives at basic block beginning to correct the rule for calculating CFA Having CFI instructions in function epilogue can cause incorrect CFA calculation rule for some basic blocks. This can happen if, due to basic block reordering, or the existence of multiple epilogue blocks, some of the blocks have wrong cfa offset and register values set by the epilogue block above them. CFIInstrInserter is currently run only on X86, but can be used by any target that implements support for adding CFI instructions in epilogue. Patch by Violeta Vukobrat.

[X86] Reduce the width of multiplification when its operands are extended from i8 or i16 For <N x i32> type mul, pmuludq will be used for targets without SSE41, which often introduces many extra pack and unpack instructions in vectorized loop body because pmuludq generates <N/2 x i64> type value. However when the operands of <N x i32> mul are extended from smaller size values like i8 and i16, the type of mul may be shrunk to use pmullw + pmulhw/pmulhuw instead of pmuludq, which generates better code. For targets with SSE41, pmulld is supported so no shrinking is needed. Differential Revision: http://reviews.llvm.org/D20931 llvm-svn: 272694

However when the operands of <N x i32> mul are extended from smaller size values like i8 and i16, the type of mul may be shrunk to use pmullw + pmulhw/pmulhuw instead of pmuludq, which generates better code. For targets with SSE41, pmulld is supported so no shrinking is needed. Differential Revision: http://reviews.llvm.org/D20931 llvm-svn: 272694

Correct dwarf unwind information in function epilogue This patch aims to provide correct dwarf unwind information in function epilogue for X86. It consists of two parts. The first part inserts CFI instructions that set appropriate cfa offset and cfa register in emitEpilogue() in X86FrameLowering. This part is X86 specific. The second part is platform independent and ensures that: * CFI instructions do not affect code generation (they are not counted as instructions when tail duplicating or tail merging) * Unwind information remains correct when a function is modified by different passes. This is done in a late pass by analyzing information about cfa offset and cfa register in BBs and inserting additional CFI directives where necessary. Added CFIInstrInserter pass: * analyzes each basic block to determine cfa offset and register are valid at its entry and exit * verifies that outgoing cfa offset and register of predecessor blocks match incoming values of their successors * inserts additional CFI directives at basic block beginning to correct the rule for calculating CFA Having CFI instructions in function epilogue can cause incorrect CFA calculation rule for some basic blocks. This can happen if, due to basic block reordering, or the existence of multiple epilogue blocks, some of the blocks have wrong cfa offset and register values set by the epilogue block above them. CFIInstrInserter is currently run only on X86, but can be used by any target that implements support for adding CFI instructions in epilogue. Patch by Violeta Vukobrat.

[X86][SSE] Aggressively use PMADDWD for v4i32 multiplies with 17 or more leading zeros As discussed in D41484, PMADDWD for 'zero extended' vXi32 is nearly always a better option than PMULLD: On SNB it will result in code that isn't any faster, but not any slower so we may as well keep it. On KNL it only has half the throughput, so I've disabled it on there - ideally there'd be a better way than this. Differential Revision: https://reviews.llvm.org/D42258 llvm-svn: 323367

[X86] Reduce the width of multiplification when its operands are extended from i8 or i16 For <N x i32> type mul, pmuludq will be used for targets without SSE41, which often introduces many extra pack and unpack instructions in vectorized loop body because pmuludq generates <N/2 x i64> type value. However when the operands of <N x i32> mul are extended from smaller size values like i8 and i16, the type of mul may be shrunk to use pmullw + pmulhw/pmulhuw instead of pmuludq, which generates better code. For targets with SSE41, pmulld is supported so no shrinking is needed. Differential Revision: http://reviews.llvm.org/D20931 llvm-svn: 272694

[X86][SSE] Aggressively use PMADDWD for v4i32 multiplies with 17 or more leading zeros As discussed in D41484, PMADDWD for 'zero extended' vXi32 is nearly always a better option than PMULLD: On SNB it will result in code that isn't any faster, but not any slower so we may as well keep it. On KNL it only has half the throughput, so I've disabled it on there - ideally there'd be a better way than this. Differential Revision: https://reviews.llvm.org/D42258 llvm-svn: 323367

[X86] Reduce the width of multiplification when its operands are extended from i8 or i16 For <N x i32> type mul, pmuludq will be used for targets without SSE41, which often introduces many extra pack and unpack instructions in vectorized loop body because pmuludq generates <N/2 x i64> type value. However when the operands of <N x i32> mul are extended from smaller size values like i8 and i16, the type of mul may be shrunk to use pmullw + pmulhw/pmulhuw instead of pmuludq, which generates better code. For targets with SSE41, pmulld is supported so no shrinking is needed. Differential Revision: http://reviews.llvm.org/D20931 llvm-svn: 272694

[X86] Reduce the width of multiplification when its operands are extended from i8 or i16 For <N x i32> type mul, pmuludq will be used for targets without SSE41, which often introduces many extra pack and unpack instructions in vectorized loop body because pmuludq generates <N/2 x i64> type value. However when the operands of <N x i32> mul are extended from smaller size values like i8 and i16, the type of mul may be shrunk to use pmullw + pmulhw/pmulhuw instead of pmuludq, which generates better code. For targets with SSE41, pmulld is supported so no shrinking is needed. Differential Revision: http://reviews.llvm.org/D20931 llvm-svn: 272694

[X86][SSE] Use PMADDWD for v4i32 multiplies with 17 or more leading zeros If there are 17 or more leading zeros to the v4i32 elements, then we can use PMADD for the integer multiply when PMULLD is unavailable or slow. The 17 bits need to be zero as the PMADDWD performs a v8i16 signed-mul-extend + pairwise-add - the upper 16 so we're adding a zero pair and the 17th bit so we don't incorrectly sign extend.

[X86] Make the MUL->VPMADDWD work before op legalization on AVX1 targets. Simplify feature checks by using isTypeLegal. The v8i32 conversion on AVX1 targets was only working after LowerMUL splits 256-bit vectors. While I was there I've also made it so we don't have to check for AVX2 and BWI directly and instead just ask if the type is legal.

Correct dwarf unwind information in function epilogue This patch aims to provide correct dwarf unwind information in function epilogue for X86. It consists of two parts. The first part inserts CFI instructions that set appropriate cfa offset and cfa register in emitEpilogue() in X86FrameLowering. This part is X86 specific. The second part is platform independent and ensures that: * CFI instructions do not affect code generation (they are not counted as instructions when tail duplicating or tail merging) * Unwind information remains correct when a function is modified by different passes. This is done in a late pass by analyzing information about cfa offset and cfa register in BBs and inserting additional CFI directives where necessary. Added CFIInstrInserter pass: * analyzes each basic block to determine cfa offset and register are valid at its entry and exit * verifies that outgoing cfa offset and register of predecessor blocks match incoming values of their successors * inserts additional CFI directives at basic block beginning to correct the rule for calculating CFA Having CFI instructions in function epilogue can cause incorrect CFA calculation rule for some basic blocks. This can happen if, due to basic block reordering, or the existence of multiple epilogue blocks, some of the blocks have wrong cfa offset and register values set by the epilogue block above them. CFIInstrInserter is currently run only on X86, but can be used by any target that implements support for adding CFI instructions in epilogue. Patch by Violeta Vukobrat.

[X86][SSE] Aggressively use PMADDWD for v4i32 multiplies with 17 or more leading zeros As discussed in D41484, PMADDWD for 'zero extended' vXi32 is nearly always a better option than PMULLD: On SNB it will result in code that isn't any faster, but not any slower so we may as well keep it. On KNL it only has half the throughput, so I've disabled it on there - ideally there'd be a better way than this. Differential Revision: https://reviews.llvm.org/D42258 llvm-svn: 323367

[X86][SSE] Use PMADDWD for v4i32 multiplies with 17 or more leading zeros If there are 17 or more leading zeros to the v4i32 elements, then we can use PMADD for the integer multiply when PMULLD is unavailable or slow. The 17 bits need to be zero as the PMADDWD performs a v8i16 signed-mul-extend + pairwise-add - the upper 16 so we're adding a zero pair and the 17th bit so we don't incorrectly sign extend.

Correct dwarf unwind information in function epilogue This patch aims to provide correct dwarf unwind information in function epilogue for X86. It consists of two parts. The first part inserts CFI instructions that set appropriate cfa offset and cfa register in emitEpilogue() in X86FrameLowering. This part is X86 specific. The second part is platform independent and ensures that: * CFI instructions do not affect code generation (they are not counted as instructions when tail duplicating or tail merging) * Unwind information remains correct when a function is modified by different passes. This is done in a late pass by analyzing information about cfa offset and cfa register in BBs and inserting additional CFI directives where necessary. Added CFIInstrInserter pass: * analyzes each basic block to determine cfa offset and register are valid at its entry and exit * verifies that outgoing cfa offset and register of predecessor blocks match incoming values of their successors * inserts additional CFI directives at basic block beginning to correct the rule for calculating CFA Having CFI instructions in function epilogue can cause incorrect CFA calculation rule for some basic blocks. This can happen if, due to basic block reordering, or the existence of multiple epilogue blocks, some of the blocks have wrong cfa offset and register values set by the epilogue block above them. CFIInstrInserter is currently run only on X86, but can be used by any target that implements support for adding CFI instructions in epilogue. Patch by Violeta Vukobrat.

[X86][SSE] Aggressively use PMADDWD for v4i32 multiplies with 17 or more leading zeros As discussed in D41484, PMADDWD for 'zero extended' vXi32 is nearly always a better option than PMULLD: On SNB it will result in code that isn't any faster, but not any slower so we may as well keep it. On KNL it only has half the throughput, so I've disabled it on there - ideally there'd be a better way than this. Differential Revision: https://reviews.llvm.org/D42258 llvm-svn: 323367
