found 430957 20070916-1 tags 430957 - fixed_upstream thanks I tried again with latest gcc-snapshot. The testcase you provided on http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32540 compiles fast. Since on gcc's bugzilla it is marked as fixed, I think that fix is in the debian package to, nor?
However the *original* testcase takes a long time to compile with -O3 again. I've come up with this testcase, that is just a very tiny change from yours (notice the additional if): int f(void); void acceptloop_th(int *t) { int options = 0; if (f()) options |= 0x1 << 0; if (f()) options |= 0x1 << 1; if (f()) options |= 0x1 << 2; if (f()) options |= 0x1 << 3; if (f()) options |= 0x1 << 4; if (f()) options |= 0x1 << 5; if (f()) options |= 0x1 << 6; if (f()) options |= 0x1 << 7; if (f()) options |= 0x1 << 8; if (f()) options |= 0x1 << 9; if (f()) options |= 0x1 << 10; if (f()) options |= 0x1 << 11; if (f()) options |= 0x1 << 12; if (f()) options |= 0x1 << 13; if (f()) options |= 0x1 << 14; if (f()) options |= 0x1 << 15; if (f()) options |= 0x1 << 16; if (f()) options |= 0x1 << 17; if (f()) options |= 0x1 << 18; if (f()) options |= 0x1 << 19; if (f()) options |= 0x1 << 20; if (f()) options |= 0x1 << 21; if (f()) options |= 0x1 << 22; if (f()) options |= 0x1 << 23; if (f()) options |= 0x1 << 24; if (f()) options |= 0x1 << 25; if (f()) options |= 0x1 << 26; if (f()) *t = options; } timings: 17 ifs: time /usr/lib/gcc-snapshot/bin/gcc -c -O3 x.c user 0m1.784s 22 ifs: time /usr/lib/gcc-snapshot/bin/gcc -c -O3 x.c Stopped after 2m25.514s (didn't finish), it was using all of available RAM (2G), and it generated lot of disk activity (swap). /usr/lib/gcc-snapshot/bin/gcc -v Using built-in specs.
