I'm also still seeing the failure of 991118-1.c. These are the remaining
new fails on hppa-unknown-linux-gnu:
FAIL: gcc.c-torture/execute/991118-1.c compilation, -O3 -fomit-frame-pointer (
internal compiler error)
FAIL: gcc.c-torture/execute/991118-1.c compilation, -O3 -g (internal compiler
error)
FAIL: gcc.c-torture/execute/longlong.c execution, -O3 -fomit-frame-pointer
FAIL: gcc.c-torture/execute/longlong.c execution, -O3 -g
