Hello,
this fixes the following testsuite regression on spu-elf:
FAIL: g++.dg/torture/pr57499.C -O1 (internal compiler error)
which was caused by a code path in pad_bb that would simply crash
if the very last active insn in a function happened to be a
"blockage".
Tested on spu-elf, committed to mainline.
Bye,
Ulrich
ChangeLog:
* config/spu/spu.c (pad_bb): Do not crash when the last
insn is CODE_FOR_blockage.
Index: gcc/config/spu/spu.c
