[DAGCombiner][X86] When promoting loads don't use ZEXTLOAD even its legal We were previously prefering ZEXTLOAD over EXTLOAD if it is legal. This triggers during X86's promotion of i16->i32. Not sure about other targets. Using ZEXTLOAD can prevent folding it to SEXTLOAD later if we were to promote a sign extended operand like we would need for SRA. However, X86 doesn't currently promote i16 SRA. I was looking into doing that which is how I found this issue. This is also blocking our ability to fold 4 byte aligned EXTLOADs with "loadi32". This is what caused most of the test changes here. Differential Revision: https://reviews.llvm.org/D45585#inline-402825 llvm-svn: 330781

[DAGCombiner][X86] When promoting loads don't use ZEXTLOAD even its legal We were previously prefering ZEXTLOAD over EXTLOAD if it is legal. This triggers during X86's promotion of i16->i32. Not sure about other targets. Using ZEXTLOAD can prevent folding it to SEXTLOAD later if we were to promote a sign extended operand like we would need for SRA. However, X86 doesn't currently promote i16 SRA. I was looking into doing that which is how I found this issue. This is also blocking our ability to fold 4 byte aligned EXTLOADs with "loadi32".

[DAGCombiner][X86] When promoting loads don't use ZEXTLOAD even its legal We were previously prefering ZEXTLOAD over EXTLOAD if it is legal. This triggers during X86's promotion of i16->i32. Not sure about other targets. Using ZEXTLOAD can prevent folding it to SEXTLOAD later if we were to promote a sign extended operand like we would need for SRA. However, X86 doesn't currently promote i16 SRA. I was looking into doing that which is how I found this issue. This is also blocking our ability to fold 4 byte aligned EXTLOADs with "loadi32".

[DAGCombiner][X86] When promoting loads don't use ZEXTLOAD even its legal We were previously prefering ZEXTLOAD over EXTLOAD if it is legal. This triggers during X86's promotion of i16->i32. Not sure about other targets. Using ZEXTLOAD can prevent folding it to SEXTLOAD later if we were to promote a sign extended operand like we would need for SRA. However, X86 doesn't currently promote i16 SRA. I was looking into doing that which is how I found this issue. This is also blocking our ability to fold 4 byte aligned EXTLOADs with "loadi32".

[DAGCombiner][X86] When promoting loads don't use ZEXTLOAD even its legal We were previously prefering ZEXTLOAD over EXTLOAD if it is legal. This triggers during X86's promotion of i16->i32. Not sure about other targets. Using ZEXTLOAD can prevent folding it to SEXTLOAD later if we were to promote a sign extended operand like we would need for SRA. However, X86 doesn't currently promote i16 SRA. I was looking into doing that which is how I found this issue. This is also blocking our ability to fold 4 byte aligned EXTLOADs with "loadi32". This is what caused most of the test changes here. Differential Revision: https://reviews.llvm.org/D45585#inline-402825 llvm-svn: 330781

[DAGCombiner][X86] When promoting loads don't use ZEXTLOAD even its legal We were previously prefering ZEXTLOAD over EXTLOAD if it is legal. This triggers during X86's promotion of i16->i32. Not sure about other targets. Using ZEXTLOAD can prevent folding it to SEXTLOAD later if we were to promote a sign extended operand like we would need for SRA. However, X86 doesn't currently promote i16 SRA. I was looking into doing that which is how I found this issue. This is also blocking our ability to fold 4 byte aligned EXTLOADs with "loadi32".

[DAGCombiner][X86] When promoting loads don't use ZEXTLOAD even its legal We were previously prefering ZEXTLOAD over EXTLOAD if it is legal. This triggers during X86's promotion of i16->i32. Not sure about other targets. Using ZEXTLOAD can prevent folding it to SEXTLOAD later if we were to promote a sign extended operand like we would need for SRA. However, X86 doesn't currently promote i16 SRA. I was looking into doing that which is how I found this issue. This is also blocking our ability to fold 4 byte aligned EXTLOADs with "loadi32". This is what caused most of the test changes here. Differential Revision: https://reviews.llvm.org/D45585#inline-402825 llvm-svn: 330781

[X86] Use a shift plus an lea for multiplying by a constant that is a power of 2 plus 2/4/8. The LEA allows us to combine an add and the multiply by 2/4/8 together so we just need a shift for the larger power of 2. llvm-svn: 337875

[X86] Add support expanding multiplies by constant where the constant is -3/-5/-9 multplied by a power of 2. These can be replaced with an LEA, a shift, and a negate. This seems to match what gcc and icc would do. llvm-svn: 338174

[DAGCombiner][X86] When promoting loads don't use ZEXTLOAD even its legal We were previously prefering ZEXTLOAD over EXTLOAD if it is legal. This triggers during X86's promotion of i16->i32. Not sure about other targets. Using ZEXTLOAD can prevent folding it to SEXTLOAD later if we were to promote a sign extended operand like we would need for SRA. However, X86 doesn't currently promote i16 SRA. I was looking into doing that which is how I found this issue. This is also blocking our ability to fold 4 byte aligned EXTLOADs with "loadi32". This is what caused most of the test changes here. Differential Revision: https://reviews.llvm.org/D45585#inline-402825 llvm-svn: 330781
