Dan Gohman	7d9dffb413	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. llvm-svn: 83670	2009-10-09 20:35:19 +00:00

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.
