The only unique regressions that occur when the gcc testsuite is run at -m64 with a power64-*-darwin* target/host compiler compared to a powerpc-*-darwin* target/host compiler at -m64 are...
XPASS: gcc.dg/cpp/cmdlne-dI-M.c scan-file (^|\\n)cmdlne-dI-M.*:[^\\n]*cmdlne-dI-M.c XPASS: gcc.dg/cpp/cmdlne-dM-M.c scan-file (^|\\n)cmdlne-dM-M[^\\n]*:[^\\n]*cmdlne-dM-M.c I assume we don't want this XPASS so this is a regression for the powerpc64-*-darwin* target. -- Summary: XPASS on cmdlne-dI-M.c and cmdlne-dM-M.c in gcc.dg/cpp Product: gcc Version: 4.2.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: howarth at nitro dot med dot uc dot edu GCC build triplet: powerpc64-apple-darwin8 GCC host triplet: powerpc64-apple-darwin8 GCC target triplet: powerpc64-apple-darwin8 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29807
