------- Additional Comments From tobi at gcc dot gnu dot org 2005-05-19 19:16 ------- It has never worked on HP-UX at least, see here, e.g.: http://gcc.gnu.org/ml/gcc-testresults/2005-05/msg00134.html
I have no idea why it would only fail at -O0 though, the .original dump on i586-linux looks fine, and there's nothing strongly system specific in it. Also, it's not a 32bit vs. 64bit issue, as can be seen from these testresults: http://gcc.gnu.org/ml/gcc-testresults/2005-05/msg01228.html -- here the test fails at -O0 for 32bits, but passes for 64bit. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21594
