kbuild: use KECHO convenience echo

2008-12-03T20:32:01Z

Convert a few echos in the build system to new $(kecho) so we get correct output according to build verbosity. Signed-off-by: Mike Frysinger [sam: added kecho in a few more places for O=... builds] Signed-off-by: Sam Ravnborg

kbuild: introduce $(kecho) convenience echo

2008-12-03T20:32:00Z

There is a bunch of places in the build system where we do 'echo' to show some nice status lines. This means we still get output when running in silent mode. So declare a new KECHO variable that only does 'echo' when we are in a suitable verbose build mode. Signed-off-by: Mike Frysinger [sam: added Documentation] Signed-off-by: Sam Ravnborg

kbuild: fix -I option expansion with O=... builds

2008-12-03T20:22:21Z

When adding extra -I options with O=... we could end up in a situation where there were no parameters to -I. So we had a commandline that looked like this: ... -I -Wall ... This had the undesired side effect that gcc assumed "-Wall" was a path to look for include files so this options was effectively ignored. This happens only when we build the generated module.mod.c files as part of the final modules builds and is as such harmless with current kbuild. This bug was exposed when we rearranged the options to gcc. Signed-off-by: Sam Ravnborg

kbuild: fix cc-option and cc-option-yn

Use -c instead of -S in cc-option and cc-option-yn, so we can probe options related to the assembler. Signed-off-by: H. Peter Anvin Cc: Sam Ravnborg Cc: kbuild devel Signed-off-by: Ingo Molnar

kbuild: fix make V=1

2008-02-11T16:43:54Z

When make -s support were added to filechk to combination created with make V=1 were not covered. Fix it by explicitly cover this case too. Signed-off-by: Sam Ravnborg Cc: Mike Frysinger

kbuild: introduce cc-cross-prefix

2007-10-19T19:46:01Z

cc-cross-prefix is useful for the architecture that like to provide a default CROSS_COMPILE value, but may have several to select between. Sample usage: ifneq ($(SUBARCH),$(ARCH)) ifeq ($(CROSS_COMPILE),) CROSS_COMPILE := $(call cc-cross-prefix, m68k-linux-gnu- m68k-linux-) endif endif Actual usage by the different archs will taken care of later.

kbuild: enable 'make AFLAGS=...' to add additional options to AS

2007-10-15T19:59:31Z

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

kbuild: enable 'make CFLAGS=...' to add additional options to CC

2007-10-14T20:21:35Z

The variable CFLAGS 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 CFLAGS with KBUILD_CFLAGS all over the tree and enabling one to use: make CFLAGS=... to specify additional gcc commandline options. One usecase is when trying to find gcc bugs but other use cases has been requested too. Patch was tested on following architectures: alpha, arm, i386, x86_64, mips, sparc, sparc64, ia64, m68k Test was simple to do a defconfig build, apply the patch and check that nothing got rebuild.
