Changes in directory llvm/test/CodeGen/X86:
2007-01-13-StackPtrIndex.ll updated: 1.3 -> 1.4
trunc-to-bool.ll updated: 1.9 -> 1.10
---
Log message:
Changes to support making the shift instructions be true BinaryOperators.
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.
