The following code: --------------------------------------------------------------------------- typedef float V8SF __attribute__ ((vector_size (32))); void test0 (V8SF); void foo (float x) { test ((V8SF) { x, x, x, x, x, x, x, x }); } ---------------------------------------------------------------------------
causes an ICE on targets for which the vector argument is callee-copied: --------------------------------------------------------------------------- /tmp/foo.c: In function 'foo': /tmp/foo.c:6: internal compiler error: in copy_constant, at varasm.c:3067 Please submit a full bug report, with preprocessed source if appropriate. See <http://gcc.gnu.org/bugs.html> for instructions. --------------------------------------------------------------------------- We try to take the address of the original CONSTRUCTOR (rather than a temporary as in the caller-copied case) and expand_expr_addr_expr_1 assumes that all constructors are constant. -- Summary: ICE for nonconstant callee-copied constructor arguments Product: gcc Version: 4.3.0 Status: UNCONFIRMED Keywords: ice-on-valid-code Severity: normal Priority: P3 Component: middle-end AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: rsandifo at gcc dot gnu dot org GCC target triplet: mipsisa32-elf http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33617
