From 222d394d30e74bb7a2a65029fcea68107b0d0eb6 Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Mon, 15 Oct 2007 21:59:31 +0200 Subject: kbuild: enable 'make AFLAGS=...' to add additional options to AS The variable AFLAGS is a wellknown variable and the usage by kbuild may result in unexpected behaviour. On top of that several people over time has asked for a way to pass in additional flags to gcc. This patch replace use of AFLAGS with KBUILD_AFLAGS all over the tree. Patch was tested on following architectures: alpha, arm, i386, x86_64, mips, sparc, sparc64, ia64, m68k, s390 Signed-off-by: Sam Ravnborg --- scripts/Kbuild.include | 2 +- scripts/Makefile.lib | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) (limited to 'scripts') diff --git a/scripts/Kbuild.include b/scripts/Kbuild.include index b1a7c7d42e15..de7bb284c611 100644 --- a/scripts/Kbuild.include +++ b/scripts/Kbuild.include @@ -81,7 +81,7 @@ as-option = $(call try-run,\ # Usage: cflags-y += $(call as-instr,instr,option1,option2) as-instr = $(call try-run,\ - echo -e "$(1)" | $(CC) $(AFLAGS) -c -xassembler -o "$$TMP" -,$(2),$(3)) + echo -e "$(1)" | $(CC) $(KBUILD_AFLAGS) -c -xassembler -o "$$TMP" -,$(2),$(3)) # cc-option # Usage: cflags-y += $(call cc-option,-march=winchip-c6,-march=i586) diff --git a/scripts/Makefile.lib b/scripts/Makefile.lib index 51ae412929a0..2837adaa9850 100644 --- a/scripts/Makefile.lib +++ b/scripts/Makefile.lib @@ -85,7 +85,7 @@ modname_flags = $(if $(filter 1,$(words $(modname))),\ -D"KBUILD_MODNAME=KBUILD_STR($(call name-fix,$(modname)))") _c_flags = $(KBUILD_CFLAGS) $(EXTRA_CFLAGS) $(CFLAGS_$(basetarget).o) -_a_flags = $(AFLAGS) $(EXTRA_AFLAGS) $(AFLAGS_$(basetarget).o) +_a_flags = $(KBUILD_AFLAGS) $(EXTRA_AFLAGS) $(AFLAGS_$(basetarget).o) _cpp_flags = $(CPPFLAGS) $(EXTRA_CPPFLAGS) $(CPPFLAGS_$(@F)) # If building the kernel in a separate objtree expand all occurrences -- cgit v1.2.3
