Bug ID: 111330
Summary: [13 Regression] Bootstrap failure building SeqFile.lo
Product: gcc
Version: 13.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: modula2
Assignee: gaius at gcc dot gnu.org
Reporter: jakub at gcc dot gnu.org
Target Milestone: ---
I've done a successful Fedora distro build of GCC 13
r13-7622-g3e9aaa9bcb2fc64e64
based snapshot and that and all earlier ones went fine, but when trying to
build
a r13-7778-g78f63dd9fa9ff29949 based snapshot, I'm seeing weird Modula 2
failures.
See https://kojipkgs.fedoraproject.org//work/tasks/4565/105824565/build.log
or https://kojipkgs.fedoraproject.org//work/tasks/4525/105824525/build.log
etc., it is all arches. What I see in the logs is:

../../gcc/m2/gm2-compiler/M2SymInit.def:1:case statement has no matching
selection
make[5]: *** [Makefile:912: SeqFile.lo] Error 1
Now, I have no idea if this case statement has no matching selection message is
an error or not and if it is, if it is what caused SeqFile.lo to fail building.
I've reproduced it in a local Fedora mock, but when I do make -j32 in the
libgm2 build directory afterwards, everything including SeqFile.lo builds fine,
so I wonder if it isn't another case of missing Makefile dependencies or
something similar.
Any ideas (including ideas what I could try to understand what's going on)?
