Evan Cheng 884c70c912 On x86 favors folding short immediate into some arithmetic operations (e.g. add, and, xor, etc.) because materializing an immediate in a register is expensive in turns of code size. ... e.g. movl 4(%esp), %eax addl $4, %eax is 2 bytes shorter than movl $4, %eax addl 4(%esp), %eax git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60139 91177308-0d34-0410-b5e6-96231b3b80d8		2008-11-27 00:49:46 +00:00
