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.

kbuild: New 'cc-fullversion' macro

2007-07-16T19:15:47Z

Prints a six-digit string including the GCC patchlevel. Also fix the 'usage' comment for cc-version. Signed-off-by: Segher Boessenkool Signed-off-by: Sam Ravnborg

[PATCH] kbuild: more Makefile cleanups

2007-02-09T18:12:20Z

This adds the remaining changes which should have been part of the review process. - the define command is inappropriate (it's primarily for rule definitions) - execute commands in the current dir as all other commands - .*.tmp (but not .*.null) files are also removed up by "make clean" - printf has other side effects, just use "echo -e" - proper quoting - proper indentation Signed-off-by: Roman Zippel Signed-off-by: Linus Torvalds

kbuild: fix space for good (take 103)

2007-02-08T16:16:44Z

Michal Ostrowski points out what the real problem was: the spaces at the start of the definition of the 'checker-shell' make function. Cc: Michal Ostrowski Acked-by: David Miller Acked-by: Geert Uytterhoeven Acked-by: Oleg Verych Signed-off-by: Linus Torvalds

kbuild: make $(checker-shell ) strip spaces around the result

2007-02-08T04:24:25Z

It looks like GNU make version 3.80 (but apparently not 3.81) adds leading whitespace to the result of the checker-shell execution. This strips them off explicitly. Also, don't bother symlinking the output file to /dev/null. It's likely as expensive as just writing the temp-file, and we need to remove it anyway afterwards. Signed-off-by: Linus Torvalds

[PATCH] kbuild, Kbuild.include: avoid using spaces in call arguments

2007-02-07T23:32:26Z

Do not use whitespace in arguments of functions in makefiles, as they propagate further without notice. Thus we get + echo ' y' instead of + echo y Fix misleading comments. Signed-off-by: Oleg Verych Signed-off-by: Linus Torvalds

[PATCH] kbuild: improve option checking, Kbuild.include cleanup

2007-02-06T22:30:49Z

GNU binutils, root users, tmpfiles, external modules ro builds must be fixed to do the right thing now. Cc: Roman Zippel Cc: Sam Ravnborg Cc: Horst Schirmeier Cc: Jan Beulich Cc: Daniel Drake Cc: Andi Kleen Cc: Randy Dunlap Signed-off-by: Oleg Verych Signed-off-by: Linus Torvalds

[PATCH] kbuild: don't put temp files in source

2006-12-10T17:55:39Z

The as-instr/ld-option need to create temporary files, but create them in the output directory, when compiling external modules. Reformat them a bit and use $(CC) instead of $(AS) as the former is used by kbuild to assemble files.
