Richard, your patch http://gcc.gnu.org/ml/gcc-cvs/2005-01/msg00288.html causes the following testcase to ICE on mainline (i686-pc-linux-gnu):
====================================================== typedef char v16qi __attribute__((vector_size(16))); void foo() { v16qi v=(v16qi)__builtin_ia32_setzero128(); } ====================================================== When compiling the test with "-msse2" the testcase used to compile on gcc 3.3.x and 3.4.x. But now I get: bug.c: In function 'foo': bug.c:6: internal compiler error: in output_constant_pool_2, at varasm.c:3122 Please submit a full bug report, [etc.] The testcase segfaults on gcc 3.3.x and gcc 3.4.x, but compiles fine with previous mainline versions when compiled with "-msse". -- Summary: [4.0 regression] ICE with SSE intrinsics Product: gcc Version: 4.0.0 Status: UNCONFIRMED Keywords: ice-on-valid-code, monitored Severity: normal Priority: P2 Component: target AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: reichelt at gcc dot gnu dot org CC: gcc-bugs at gcc dot gnu dot org,rth at gcc dot gnu dot org GCC target triplet: i686-pc-linux-gnu http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19356
