------- Additional Comments From rosbacke at nada dot kth dot se 2004-01-10 19:00 ------- Good to see that the ICE got removed by the patch. But I'm afraid this might lead us to cover the bug rather than fixing. I don't know much off gcc internals but I can give you some notes from my work to create the second test case.
It seemed to be rather sensitive to acually perfoming floating point divisions. For example replacing '1./3.' with '0.33' would remove the ICE. changing '* p / 3' to '* p * 3' would remove the ICE. Also replacing 'pow( 1./ 3. )' with 'pow(1/3)' would remove the ICE. Also it seemed important that 'while(i<6) ++i;' occured between 'p = ...' and the return statement. Placing 'while(i<6) ++i;' above the assignment to p would also remove the ICE. >From these totally unscientific observations I would guess that we would have a problem somewhere in the code that handles division of floating point numbers with -ffast-math. Maybe worth having a look at? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=13634 ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
