Chris Lattner edd5e4957a Implement negation of longs efficiently. For this testcase: ... long %test(long %X) { %Y = sub long 0, %X ret long %Y } We used to generate: test: sub %ESP, 4 mov DWORD PTR [%ESP], %ESI mov %ECX, DWORD PTR [%ESP + 8] mov %ESI, DWORD PTR [%ESP + 12] mov %EAX, 0 mov %EDX, 0 sub %EAX, %ECX sbb %EDX, %ESI mov %ESI, DWORD PTR [%ESP] add %ESP, 4 ret Now we generate: test: mov %EAX, DWORD PTR [%ESP + 4] mov %EDX, DWORD PTR [%ESP + 8] neg %EAX adc %EDX, 0 neg %EDX ret git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12681 91177308-0d34-0410-b5e6-96231b3b80d8		2004-04-06 01:48:06 +00:00
