Bug ID: 95840
Summary: Parallel build fails due to missing "gcc/xgcc"
Product: gcc
Version: 9.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: testsuite
Assignee: unassigned at gcc dot gnu.org
Reporter: enrico.scholz+bugs...@sigma-chemnitz.de
Target Milestone: ---

fixes race in "make -j"
When doing a parallel build of gcc (e.g. for OpenEmbedded and using GNU make
4.2), I get often
| make[1]: ...././gcc/xgcc: Command not found
| make[1]: *** [..../gcc/cp/Make-lang.in:178: s-selftest-c++] Error 127
| make[1]: *** Waiting for unfinished jobs....
| make[1]: Leaving directory '..../gcc'
| make: *** [Makefile:4328: all-gcc] Error 2
Makefile does
| include c/Make-lang.in
| ...
| C_SELFTEST_DEPS = cc1$(exeext) $(SELFTEST_DEPS)
| ...
| s-selftest-c: $(C_SELFTEST_DEPS)
|
| SELFTEST_DEPS = $(GCC_PASSES) stmp-int-hdrs $(srcdir)/testsuite/selftests
which means that $(SELFTEST_DEPS) are expanded in the language fragment
files before they are defined in the main make file.
Attached patch (against 9.3.0) fixes this.
