> * builtins.c (expand_builtin_setjmp_receiver): Update comment
> regarding purpose of blockage.
> * emit-rtl.c [!HAVE_blockage] (gen_blockage): Similarly for
> the head comment.
> * rtlanal.c (volatile_insn_p): Ditto.
> * doc/md.texi (blockage): Update similarly. Change wording to
> require one of two forms, rather than implying a wider choice.
> * cse.c (cse_insn): Where checking for blocking insns, use
> volatile_insn_p instead of manual check for volatile ASM.
> * dse.c (scan_insn): Ditto.
> * cselib.c (cselib_process_insn): Ditto.
This patch broke bootstrap on s390x.
