2007-02-04Fix a miscompilation in the addr mode code trying to implement X | C andChris Lattner
X + C to promote LEA formation. We would incorrectly apply it in some cases (test) and miss it in others. This fixes CodeGen/X86/2007-02-04-OrAddrMode.ll git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33884 91177308-0d34-0410-b5e6-96231b3b80d8

2007-02-02Changes to support making the shift instructions be true BinaryOperators.Reid Spencer
This feature is needed in order to support shifts of more than 255 bits on large integer types. This changes the syntax for llvm assembly to make shl, ashr and lshr instructions look like a binary operator: shl i32 %X, 1 instead of shl i32 %X, i8 1 Additionally, this should help a few passes perform additional optimizations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33776 91177308-0d34-0410-b5e6-96231b3b80d8

2007-01-30- Fix codegen for pc relative constant (e.g. JT) in thumb mode:Evan Cheng
.set PCRELV0, (LJTI1_0_0-(LPCRELL0+4)) LPCRELL0: add r1, pc, #PCRELV0 This is not legal since add r1, pc, #c requires the constant be a multiple of 4. Do the following instead: .set PCRELV0, (LJTI1_0_0-(LPCRELL0+4)) LPCRELL0: mov r1, #PCRELV0 add r1, pc - In thumb mode, it's not possible to use .set generate a pc relative stub address. The stub is ARM code which is in a different section from the thumb code. Load the value from a constpool instead. - Some asm printing clean up. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33664 91177308-0d34-0410-b5e6-96231b3b80d8
