Bug ID: 71889
Summary: [5.4 Regression] [MIPS] python: "insn does not satisfy
its constraints"
Product: gcc
Version: 5.4.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org

_codecs_cn.preprocessed.c
Compiling Python-2.7.11/Modules/cjkcodecs/_codecs_cn.c with gcc-5.4.0 on MIPS
with -O2 results in "insn does not satisfy its constraints" error (full in
attachment).
When instead of -O2 I try all the -f flags that are specified by manpage to be
implied by -O2 (and -O1), compilation is successful - I thus think that there
are some more -f options implied (which are not in the manpage) or there is
some other error.
I am 98% sure that this was an error in 5.3.0 as well.
Attached preprocessed _codecs_cn.c and also commands used for both
compilations.
