           Summary: [10/11/12 Regression] 32bit mips: Error: branch out of
                    range
           Product: gcc
           Version: 10.3.0

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
