Bug ID: 117227
Summary: Missing modula2 plugin dependencies
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: minor
Priority: P3
Component: modula2
Assignee: gaius at gcc dot gnu.org
Reporter: tschwinge at gcc dot gnu.org
Target Milestone: ---
I like doing incremental GCC builds, which generally works fine (within reason,
of course).
Recently I ran into a case where some GCC diagnostics changes had gone in, and
after that, 'make check-gcc-m2' had ~100 '[-PASS:-]{+FAIL:+}' regressions, due
to:
*** WARNING *** there are active plugins, do not report this as a bug
unless you can reproduce it without enabling any plugins.

PLUGIN_FINISH | m2rte
during GIMPLE pass: runtime_exception_inevitable
In function ‘_M2_modulusoverflow_fini’:
cc1gm2: internal compiler error: tree check: expected tree that contains
‘identifier’ structure, have ‘function_decl’ in examine_function_decl, at

I noticed that 'build-gcc/gcc/plugin/m2rte.so' had not been rebuilt; after 'rm
build-gcc/gcc/plugin/m2rte.so' plus another incremental 'make' to rebuild the
plugin, these FAILs were back to PASSes. Therefore, I conclude that there are
some missing modula2 plugin dependencies;
'gcc/m2/Make-lang.in:plugin/m2rte$(soext)' or thereabouts?
