The bootstrap comparison failure appears to be gone in a c-only build of

It's expand_call(), initialize_argument_information(),
precompute_register_parameters(), or load_register_parameters() that gets
miscompiled in stage2. expand_call() is an externa

It's calls.c that gets miscompiled. If stage2 cc1 is relinked with calls.o
from stage1 then it generates the same code for alloca.c as stage1 does. If
stage1 cc1 is relinked with

The smallest .o file that fails bootstrap comparison is libiberty/alloca.o,
which get 150 bytes of .text with stage1 xgcc but 148 bytes of text with stage2
and stage3 xgcc (same op

`size' shows .text size differences, diffing objdump -d outputs shows what
looks like register allocation changes. E.g. on libiberty/objalloc.o:
