commit b4bbedb1e75737a80bcc3d53d6eef1fbe0b5f4d5
Author: H.J. Lu <hjl.tools@gmail.com>
Date: Sat Nov 6 14:13:27 2021 -0700
dso-ordering-test.py: Put all sources in one directory [BZ #28550]
Put all sources for DSO sorting tests in the dso-sort-tests-src directory
and compile test 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)
to avoid random $< values from $(before-compile) when compiling test
relocatable objects with
$(objpfx)%$o: $(objpfx)%.c $(before-compile); $$(compile-command.c)
compile-command.c = $(compile.c) $(OUTPUT_OPTION) $(compile-mkdep-flags)
compile.c = $(CC) $< -c $(CFLAGS) $(CPPFLAGS)
for 3 "make -j 28" parallel builds on a machine with 112 cores at the
same time.
This partially fixes BZ #28550.
