------- Additional Comments From ebotcazou at gcc dot gnu dot org 2004-11-22 08:48 -------
It is the cause of the following regressions on UltraSPARC 32-bit:
FAIL: gcc.c-torture/execute/simd-2.c execution, -O3 -fomit-frame-pointer
FAIL: gcc.c-torture/execute/simd-2.c execution, -O3 -g
The failure looks very similar to the one in the vector code on PowerPC.
