Evan Cheng 0b0cd9113a Optimize some 64-bit multiplication by constants into two lea's or one lea + shl since imulq is slow (latency 5). e.g. ... x * 40 => shlq $3, %rdi leaq (%rdi,%rdi,4), %rax This has the added benefit of allowing more multiply to be folded into addressing mode. e.g. a * 24 + b => leaq (%rdi,%rdi,2), %rax leaq (%rsi,%rax,8), %rax git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@67917 91177308-0d34-0410-b5e6-96231b3b80d8		2009-03-28 05:57:29 +00:00
