Hello,
the new gcc.c-torture/compile/pr48767.c test cases were all crashing the
compiler on SPU, for a similar reason as on the SH where this problem
was originally found.
Fixed by calling the common code pass_by_reference routine instead of
calling spu_pass_by_reference directly. The common code routine has
additional checks that catch the case causing the crash.
Tested on spu-elf, commited to mainline.
Bye,
Ulrich
ChangeLog:
* config/spu/spu.c (spu_gimplify_va_arg_expr): Call pass_by_reference
instead of spu_pass_by_reference.
