------- Additional Comments From pinskia at gcc dot gnu dot org 2004-07-20 08:52 ------- I get a slightly different ICE now: pr16225.c: In function `btbl_bitcnt': pr16225.c:9: internal compiler error: in may_propagate_copy, at tree-ssa-copy.c:130 Please submit a full bug report, with preprocessed source if appropriate. See <URL:http://gcc.gnu.org/bugs.html> for instructions.
Here is a little simpler code: typedef unsigned long uint32; int ntbl_bitcnt(uint32 x); int btbl_bitcnt(uint32 x); char bits[256]; int btbl_bitcnt(uint32 x) { int cnt = *(char *)&x; if (0L != (x >>= 8)) return btbl_bitcnt(x); return cnt; } oh it looks like tree-loop-ch which causing this. Maybe this is the going in and out of ssa which is causing this problem and causing to loose aliasing info. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=16225 ------- You are receiving this mail because: ------- You reported the bug, or are watching the reporter.
