We already do so when exception handling is enabled. It will change the code with -g. This isn't good in general but wouldn't be a real problem in the above situation because if such movement of the frame insn happened, then no one can expect -g works well in the first place. -- Summary: SH: ICE in dwarf2out_begin_epilogue, at dwarf2out.c:2689 Product: gcc Version: 4.5.0 Status: UNCONFIRMED Keywords: ice-on-valid-code Severity: normal Priority: P3 Component: target AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: kkojima at gcc dot gnu dot org GCC target triplet: sh-unkonwn-elf http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40313 ^ permalink raw reply [flat|nested] 4+ messages in thread
