New Revision: 335912
URL: https://svnweb.freebsd.org/changeset/base/335912
Log:
Fix .depend.foo.o tracking for sys/conf/files defined compilations.
Some example files:
ia32_genassym.o
acpi_wakecode.o
The old mkdep method also lacked tracking these files.
Objects defined in sys/conf/files with no-obj and no-implicit-rule get their
own targets defined in the kernel Makefile but lack having their objects added
to DEPENDOBJS so never get a .depend file generated. Normally if an object is
in OBJS it will get a .depend file.
Fix this by looking for .o files in CLEAN and ensuring they are part of
the -MD filtering and .depend loading. This is a hack. Other solutions
could exist involving sys/conf/files or config(8) to auto add these to
DEPENDFILES/DEPENDOBJS but this method seems reliable enough without being
intrusive or error-prone for new files.
