[x86] NFC: Clean up two tests and generate precise checks for them. Mostly this involved giving unnamed values names and running the IR through `opt` to re-format it but merging in any important comments in the original. I then deleted pointless comments and inlined the function attributes for ease of reading and editting. All of this is to make it much easier to see the instructions being generated here and evaluate any updates to the tests. llvm-svn: 311634

For something like uint32_t hi(uint64_t res) { uint_32t hi = res >> 32; return !hi; } llvm IR looks like this: define i32 @hi(i64 %res) nounwind uwtable ssp { entry: %lnot = icmp ult i64 %res, 4294967296 %lnot.ext = zext i1 %lnot to i32 ret i32 %lnot.ext } The optimizer has optimize away the right shift and truncate but the resulting constant is too large to fit in the 32-bit immediate field.

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] Handle COPYs of physregs better (regalloc hints) Enable enableMultipleCopyHints() on X86. Original Patch by @jonpa: While enabling the mischeduler for SystemZ, it was discovered that for some reason a test needed one extra seemingly needless COPY (test/CodeGen/SystemZ/call-03.ll). The handling for that is resulted in this patch, which improves the register coalescing by providing not just one copy hint, but a sorted list of copy hints. On SystemZ, this gives ~12500 less register moves on SPEC, as well as marginally less spilling. Instead of improving just the SystemZ backend, the improvement has been implemented in common-code (calculateSpillWeightAndHint(). This gives a lot of test failures, but since this should be a general improvement I hope that the involved targets will help and review the test updates.

[x86] NFC: Clean up two tests and generate precise checks for them. Mostly this involved giving unnamed values names and running the IR through `opt` to re-format it but merging in any important comments in the original. I then deleted pointless comments and inlined the function attributes for ease of reading and editting. All of this is to make it much easier to see the instructions being generated here and evaluate any updates to the tests. llvm-svn: 311634

[X86] Replace AND+IMM64 with SRL/SHL Emit SHRQ/SHLQ instead of ANDQ with a 64 bit constant mask if the result is unused and the mask has only higher/lower bits set. For example, with this patch LLVM emits shrq $41, %rdi je instead of movabsq $0xFFFFFE0000000000, %rcx testq %rcx, %rdi je This reduces number of instructions, code size and register pressure. The transformation is applied only for cases where the mask cannot be encoded as an immediate value within TESTQ instruction. Differential Revision: https://reviews.llvm.org/D28198 llvm-svn: 291806
