Bug ID: 102602
Summary: [10/11/12 Regression] 32bit mips: Error: branch out of
range
Product: gcc
Version: 10.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: bunk at stusta dot de
Target Milestone: ---
Created attachment 51552
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=51552&action=edit
Preprocessed sources
With a command like
/usr/lib/gcc/mipsel-linux-gnu/10/cc1plus -fpreprocessed Options.ii -mel -quiet
-dumpbase Options.ii -march=mips32r2 -auxbase Options -O2 -version -o
/tmp/cccmq2Yu.s
the attached file from a failed build of https://tracker.debian.org/pkg/kstars
generates code the assembler rejects.
$ g++-10 -c -O2 Options.ii

The function is huge so I really doubt that this is a regression either.

Most likley exposed by r10-9646 which introduced more inlining or rather fixing
an inlining issue which was broken in the GCC 10 series.
This most likely was broken in GCC 9 too.
The function is really just huge. I really doubt there is much to be done.
