- Subject: [PATCH] Fix PR target/33474 ICE in bfin_adjust_cost
bfin_adjust_cost() ICEs on an insn with a parallel:
(parallel [
(set (reg:PDI 33 A1)
(mem/c:PDI (plus:SI (reg/f:SI 15 FP)
(const_int -16 [0xfffffff0])) [23 S8 A32]))
(clobber (reg:SI 0 R0))
])
This patch fixes it by extracting the SET inside the parallel. Tested by
building a cross compiler for bfin-unknown-elf and seeing that it now
compiles the file it choked on before. Ok for trunk?
