[Bug c/25678] New: -m68000 doesn't work
When gcc is called with -m68000 -Wa,-m68000 it may still generate bsr.l instructions which are only supported with -m68020 and above. The assembler obviously rejects those; but if -m68000 is specified, they shouldn't be there in the first place. -- Summary: -m68000 doesn't work Product: gcc Version: 4.0.3 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: wouter at grep dot be GCC build triplet: m68k-linux GCC host triplet: m68k-linux GCC target triplet: m68k-linux http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25678
[Bug target/25642] optimizer bug: registers are clobbered but not restored
--- Comment #2 from wouter at grep dot be 2006-01-04 19:51 --- (In reply to comment #0) I found that the compiler produces code which assumes that no register inside the called function will clobber any register. Uh -- for clarity, I meant to say that no code inside the called function will clobber any register here... -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25642
[Bug c++/25642] New: optimizer bug: registers are clobbered but not restored
Hi, As explained in Debian bug#345574 (http://bugs.debian.org/345574), g++ fails to build cppunit due to a test suite failure. Debugging this, I found that the compiler produces code which assumes that no register inside the called function will clobber any register. As it turns out, that's an incorrect assumption.
