From 9f8501582f1c60c0a631a89499fb81d8f197fb30 Mon Sep 17 00:00:00 2001 From: Keir Fraser Date: Mon, 12 Jan 2009 10:16:05 +0000 Subject: Use -MMD -MF in tools/* rather than -Wp,-M... If you use -MMD -MF then the correct .o filename is written to the .*.d file as the compiler driver arranges everything. This was done in 19010:275abe1c5d24 for the hypervisor. In this patch we do the same elsewhere in the xen-unstable tree, particularly tools/. Specifically: * Change tools/Rules.mk to add -MMD -MF ... to CFLAGS and set DEPS. * Remove -Wp,-MD... from every other Makefile * Remove setting of DEPS from every other Makefile * Ensure that every Makefile says -include $(DEPS) * Ensure that every Makefile's clean target removes $(DEPS) Some Makefiles were already halfway there, but often for a different variable name eg PROG_DEP. The variable name is now standardised in Rules.mk as DEPS. I have done a test build with this change, on Debian etch.
