------- Comment #16 from ebotcazou at gcc dot gnu dot org  2009-02-08 17:59 -------
Still present on SPARC 32-bit on the mainline:

FAIL: gcc.c-torture/execute/pr38819.c execution,  -O2 
FAIL: gcc.c-torture/execute/pr38819.c execution,  -O3 -fomit-frame-pointer 
FAIL: gcc.c-torture/execute/pr38819.c execution,  -O3 -fomit-frame-pointer
-funroll-loops 
FAIL: gcc.c-torture/execute/pr38819.c execution,  -O3 -fomit-frame-pointer
-funroll-all-loops -finline-functions 
FAIL: gcc.c-torture/execute/pr38819.c execution,  -O3 -g

The culprit is RTL PRE GCSE.
