* Emit x86 instructions for: A = B op C, where A and B are 16-bit registers,Chris Lattner2003-10-203-0/+94
| | | | | | | | | | | | | | | | | | | | | | | C is a constant which can be sign-extended from 8 bits without value loss, and op is one of: add, sub, imul, and, or, xor. This allows the JIT to emit the one byte version of the constant instead of the two or 4 byte version. Because these instructions are very common, this can save a LOT of code space. For example, I sampled two benchmarks, 176.gcc and 254.gap. BM Old New Reduction 176.gcc 2673621 2548962 4.89% 254.gap 498261 475104 4.87% Note that while the percentage is not spectacular, this did eliminate 124.6 _KILOBYTES_ of codespace from gcc. Not bad. Note that this doesn't effect the llc version at all, because the assembler already does this optimization. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9284 91177308-0d34-0410-b5e6-96231b3b80d8
