Subject: (optimize_bit_field): Put any insns made by change_address in front of INSN.
X-Git-Tag: misc/cutover-egcs-0~5809
X-Git-Url: https://gcc.gnu.org/git/?a=commitdiff_plain;h=b88a3142921977eaf465ba2c947b1a3b09bae896;p=gcc.git

(optimize_bit_field): Put any insns made by change_address in front of INSN.

(expand_function_end): Don't pass DECL_INITIAL to setjmp_protect if it is
error_mark_node.
