Subject: [PATCH v2 0/2] Update Makefile fragments for DSO sorting tests
Date: Mon, 8 Nov 2021 07:42:09 -0800 [thread overview]
Message-ID: <20211108154211.167829-1-hjl.tools@gmail.com> (raw)
One problem of using
$(objpfx)%$o: $(objpfx)%.c $(before-compile); $$(compile-command.c)
compile-command.c = $(compile.c) $(OUTPUT_OPTION) $(compile-mkdep-flags)
compile.c = $(CC) $< -c $(CFLAGS) $(CPPFLAGS)
to build DSO sorting relocatable objects is that $< may not be the source
file with 3 "make -j 28" parallel builds on a machine with 112 cores.
When generating Makefile fragments at build time, the same file may be
generated more than once at the same time with parallel builds.
1. Update dso-ordering-test.py to put all sources for DSO sorting tests
in a single directory, dso-sort-tests-src, and compile relocatable objects
with
$(objpfx)tst-dso-ordering1-dir/tst-dso-ordering1-a.os: $(objpfx)dso-sort-tests-src/tst-dso-ordering1-a.c
$(compile.c) $(OUTPUT_OPTION)
2. Generate Makefile fragments for DSO sorting tests at configure time
to avoid generate them in the elf directory at build time.
