* [Bug rtl-optimization/26098] New: ICE in multiplication of 16-byte longlong vector on x86_64 @ 2006-02-04 20:00 bisqwit at iki dot fi 2006-02-04 20:11 ` [Bug target/26098] [4.0 Regression] " pinskia at gcc dot gnu dot org ` (4 more replies) 0 siblings, 5 replies; 6+ messages in thread From: bisqwit at iki dot fi @ 2006-02-04 20:00 UTC (permalink / raw) To: gcc-bugs This code causes ICE on gcc 4.0.3 on x86_64. typedef long long vec __attribute__ ((vector_size(16))); vec vecsqr(vec a) { return a*a; } Commandline: gcc -O1 -S -o - tmp.c Resulting output: .file "tmp.c" tmp.c: In function 'vecsqr': tmp.c:2: error: unrecognizable insn: (insn 13 12 15 0 (set (reg:DI 58 [ D.1470 ]) (vec_select:DI (reg/v:V2DI 61 [ a ]) (parallel [ (const_int 1 [0x1]) ]))) -1 (nil) (expr_list:REG_DEAD (reg/v:V2DI 61 [ a ]) (nil))) tmp.c:2: internal compiler error: in extract_insn, at recog.c:2020 It goes ICE on when -O option >= 1. -O0 does not trigger it. Option -mno-sse also disables the ICE, but then it gives "error: SSE register return with SSE disabled". -mno-sse2 doesn't disable it. Unsigned/signed type has no effect to result. Without __attribute__((vector_size)), it does not ICE. GCC version (gcc -v): Using built-in specs.
