Subject: [Bug tree-optimization/31152]  New: -(x>y) generates wrong code
Date: Mon, 12 Mar 2007 17:36:00 -0000	[thread overview]
Message-ID: <bug-31152-895@http.gcc.gnu.org/bugzilla/> (raw)

The actual gcc version is

gcc version 4.1.2 20061115 (prerelease) (Debian 4.1.1-21)

When compiled and run with this gcc version, using the command line

gcc -O xxx.c && a.out

the attached program outputs -1, whereas the correct output is 0.  If
I use gcc 3.3.6 or leave away the -O flag, the program produces
correct output.
