With LAST_UPDATED: "Mon Nov 15 19:30:07 UTC 2004" I get:
gcc.c-torture/execute/simd-4.c execution,  -O0
gcc.c-torture/execute/simd-4.c execution,  -O1
gcc.c-torture/execute/simd-4.c execution,  -O2
gcc.c-torture/execute/simd-4.c execution,  -O3 -fomit-frame-pointer
gcc.c-torture/execute/simd-4.c execution,  -O3 -g
gcc.c-torture/execute/simd-4.c execution,  -Os

With the message in gcc.log being:
*** EXIT code 4242
(a call to abort)

Last known to work on: "Mon Nov 15 13:25:54 UTC 2004".
Earliest known to fail with: "Mon Nov 15 19:30:07 UTC 2004".

Apparently the last change to that test has a bug.
It looks like an assumption that "long" is twice the size
of "long long", which is the same size for mmix-*-*
(and supposedly also some other LP64 targets).
The test needs to be tweaked, perhaps using __attribute__ ((__mode__ (SI))) for
the half-the-long-long types.
