* [Bug target/21742] New: unrecognized insn for struct-layout-1 tests with complex members @ 2005-05-24 20:55 janis at gcc dot gnu dot org 2005-05-24 20:56 ` [Bug target/21742] " janis at gcc dot gnu dot org ` (6 more replies) 0 siblings, 7 replies; 8+ messages in thread From: janis at gcc dot gnu dot org @ 2005-05-24 20:55 UTC (permalink / raw) To: gcc-bugs [-- Warning: decoded text below may be mangled, UTF-8 assumed --] [-- Attachment #1: Type: text/plain, Size: 2136 bytes --] Generated tests t154 and t199 from gcc.dg/compat/struct-layout-1 fail with an ICE compiling c_compat_y_tst.o with -m64 on powerpc64-linux. The first started failing on 20050424, the second on 20050501, and both have failed regularly since then, but it seems to be a latent bug because results for regression hunts don't match up with those dates. I'll attach minimized test cases for both. Here's the output I get from today's mainline: elm3b11% /opt/gcc-nightly/mline/bin/gcc -m64 -c bug_t154.c bug_t154.c: In function check13995: bug_t154.c:36: error: unrecognizable insn: (insn 25 24 26 1 (set (reg:DF 130 [ D.1250+8 ]) (subreg:DF (mem/s/j:DC (plus:DI (reg/f:DI 114 virtual-stack-vars) (const_int 33112 [0x8158])) [0 <variable>.e.m+0 S16 A64]) 8)) -1 (nil) (nil)) bug_t154.c:36: internal compiler error: in extract_insn, at recog.c:2082 elm3b11% /opt/gcc-nightly/mline/bin/gcc -m64 -c bug_t199.c bug_t199.c: In function check18102: bug_t199.c:23: error: unrecognizable insn: (insn 29 28 30 1 (set (reg:SF 130 [ D.1239+4 ]) (subreg:SF (mem/s/j:SC (plus:DI (reg/f:DI 114 virtual-stack-vars) (const_int 56000 [0xdac0])) [0 arg2.y+0 S8 A512]) 4)) -1 (nil) (nil)) bug_t199.c:23: internal compiler error: in extract_insn, at recog.c:2082 -- Summary: unrecognized insn for struct-layout-1 tests with complex members Product: gcc Version: 4.1.0 Status: UNCONFIRMED Severity: normal Priority: P2 Component: target AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: janis at gcc dot gnu dot org CC: gcc-bugs at gcc dot gnu dot org GCC build triplet: powerpc64-linux GCC host triplet: powerpc64-linux GCC target triplet: powerpc64-linux http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21742 ^ permalink raw reply [flat|nested] 8+ messages in thread
