I think the problem is that the tree-ssa is finding some common sub expressions and combining them which is causing reload (the register spiller) to fail to find registers/offsets for the contstraints. -- What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |NEW Component|inline-asm |optimization Ever Confirmed| |1 Last reconfirmed|0000-00-00 00:00:00 |2004-01-25 01:48:41 date| | Summary|Fails to compile ffmpeg on |[tree-ssa] Fails to compile |x86: can't find a register |ffmpeg on x86: can't find a |in class `GENERAL_REGS' |register in class |while reloading `asm' |`GENERAL_REGS' while | |reloading `asm' Target Milestone|--- |tree-ssa http://gcc.gnu.org/bugzilla/show_bug.cgi?id=13850
