Dan Gohman	11596ed43c	Fix the x86 test-shrink optimization so that it doesn't shrink comparisons when one of the bits being tested would end up being the sign bit in the narrower type, and a signed comparison is being performed, since this would change the result of the signed comparison. This fixes PR5132. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83670 91177308-0d34-0410-b5e6-96231b3b80d8	2009-10-09 20:35:19 +00:00

Fix the x86 test-shrink optimization so that it doesn't shrink comparisons

when one of the bits being tested would end up being the sign bit in the
narrower type, and a signed comparison is being performed, since this would
change the result of the signed comparison. This fixes PR5132.
