From: Sam Ravnborg Date: Mon, 15 Oct 2007 19:59:31 +0000 (+0200) Subject: kbuild: enable 'make AFLAGS=...' to add additional options to AS X-Git-Tag: v2.6.24-rc1~830^2~3 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=222d394d30e74bb7a2a65029fcea68107b0d0eb6;p=linux-2.6 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 --- diff --git a/Documentation/kbuild/makefiles.txt b/Documentation/kbuild/makefiles.txt index 1ca535bcc8..f4779cd154 100644 --- a/Documentation/kbuild/makefiles.txt +++ b/Documentation/kbuild/makefiles.txt @@ -424,6 +424,7 @@ more details, with real examples. as-instr checks if the assembler reports a specific instruction and then outputs either option1 or option2 C escapes are supported in the test instruction + Note: as-instr-option uses KBUILD_AFLAGS for $(AS) options cc-option cc-option is used to check if $(CC) supports a given option, and not @@ -819,14 +820,14 @@ When kbuild executes, the following steps are followed (roughly): In this example, the binary $(obj)/image is a binary version of vmlinux.
