From: "pinskia at gcc dot gnu dot org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug middle-end/37285] New: [4.4 Regression] ICE while building binutils on ppc Date: Sat, 30 Aug 2008 01:30:00 -0000 [thread overview] Message-ID: <bug-37285-6528@http.gcc.gnu.org/bugzilla/> (raw) Hi, it looks like some of the VRP enhancements for switch statements is causing an ICE on some code in binutils. Testcase: _bfd_xcoff_canonicalize_dynamic_reloc (unsigned long long l_symndx) { if (l_symndx < 3) { switch (l_symndx) { case 0: case 1: break; case 2: _bfd_abort ("HI"); } } } --- CUT --- With VRP turned on we get: switch (l_symndx) <case 0 ... 1: <L4>, case 2: <L3>> But without it turned on we get: switch (l_symndx) <default: <L4>, case 2: <L3>> Most likely caused by the patch to fix PR 14495. -- Summary: [4.4 Regression] ICE while building binutils on ppc Product: gcc Version: 4.4.0 Status: UNCONFIRMED Keywords: ice-on-valid-code Severity: normal Priority: P3 Component: middle-end AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: pinskia at gcc dot gnu dot org GCC target triplet: powerpc-unknown-linux-gnu http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37285
