* | | | | Kbuild: Add option to set -femit-struct-debug-baseonlyAndi Kleen2010-07-141-0/+4

What it does is to only emit type information for structures when the structures are defined in the same file or in a header file. This means the type information for most headers are not included. This is not good when the type information is actually needed (e.g. with kgdb or systemtap) But often kernel hackers only care about line numbers and don't need all the type information anyways. In this case setting the option can be a big win: A build dir for a specific x86-64 configuration with gcc 4.5 shrunk from 2.3G to 1.2G. The compilation was also nearly a minute faster.

| |/ / |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that we run scripts/setlocalversion during every build, it makes sense to move all the localversion logic there. This cleans up the toplevel Makefile and also makes sure that the script is called only once in 'make prepare' (previously, it would be called every time due to a variable expansion in an ifneq statement). No user-visible change is intended, unless one runs the setlocalversion script directly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Better dwarf2 unwind information is a good thing, it allows better debugging with kgdb and crash and helps systemtap. Commit 003086497f07f7f1e67c0c295e261740f822b377 ("Build with -fno-dwarf2-cfi-asm") disabled some CFI information globally to work around a module loader bug on powerpc. But this disables the better unwind tables for all architectures, not just powerpc. Move the workaround to powerpc and also add a suitable comment that's it really a workaround. This improves dwarf2 unwind tables on x86 at least.

This allows users to uniquely identify their kernel builds with a string. If CONFIG_LOCALVERSION_AUTO is enabled, the unique SCM tag reported by setlocalversion (or .scmversion) is appended to the kernel version, if it exists. When CONFIG_LOCALVERSION_AUTO is not enabled, a `+' is appended to the kernel version to represent that the kernel has been revised since the last release unless "make LOCALVERSION=" was used to uniquely identify the build. The end result is this: - when LOCALVERSION= is passed to "make", it is appended to the kernel version, - when CONFIG_LOCALVERSION_AUTO is enabled, a unique SCM identifier is appended if the respository has been revised beyond a tagged commit, and - when CONFIG_LOCALVERSION_AUTO is disabled, a `+' is appended if the repository has been revised beyond a tagged commit and LOCALVERSION= was not passed to "make". Examples: With CONFIG_LOCALVERSION_AUTO: "make" results in v2.6.32-rc4-00149-ga3ccf63. If there are uncommited changes to the respository, it results in v2.6.32-rc4-00149-ga3ccf63-dirty. If "make LOCALVERSION=kbuild" were used, it results in v2.6.32-rc4-kbuild-00149-ga3ccf63-dirty. Without CONFIG_LOCALVERSION_AUTO, "make" results in v2.6.32-rc4+ unless the repository is at the Linux v2.6.32-rc4 commit (in which case the version would be v2.6.32-rc4). If "make LOCALVERSION=kbuild" were used, it results in v2.6.32-rc4-kbuild. Also renames variables such as localver-auto and _localver-auto to more accurately describe what they represent: localver-extra and scm-identifier, respectively.

* | kconfig CROSS_COMPILE optionRoland McGrath2010-02-021-0/+3
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds CROSS_COMPILE as a kconfig string so you can store it in .config. Then you can use plain "make" in the configured kernel build directory to do the right cross compilation without setting the command-line or environment variable every time. With this, you can set up different build directories for different kernel configurations, whether native or cross-builds, and then use the simple: make -C /build/dir M=module-source-dir idiom to build modules for any given target kernel, indicating which one by nothing but the build directory chosen. I tried a version that defaults the string with env="CROSS_COMPILE" so that in a "make oldconfig" with CROSS_COMPILE in the environment you can just hit return to store the way you're building it. But the kconfig prompt for strings doesn't give you any way to say you want an empty string instead of the default, so I punted that.

* Makefile: do not override LC_CTYPEMichal Marek2010-01-131-2/+1
| | | | | | | | | | | | | | | | | | | | | Setting LC_CTYPE=C breaks localized messages in some setups. With only LC_COLLATE=C and LC_NUMERIC=C, we get almost all we need, except for not so defined character classes and tolower()/toupper(). The former is not a big issue, because we can assume that e.g. [:alpha:] will always include a-zA-Z and we only ever process ASCII input. The latter seems only affect arch/sh/tools/gen-mach-types, which we can handle separately. So after this patch the meaning of ranges like [a-z], the behavior of sort and join, etc. should be the same everywhere and at the same time gcc should be able to print localized waring and error messages. LC_NUMERIC=C might not be necessary, but setting it doesn't hurt. Reported-by: Simon Horman <horms@verge.net.au> Reported-by: Sergei Trofimovich <slyfox@inbox.ru> Acked-by: H.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | The namespace used in arch/$ARCH/include is different from what is used in include/ except for the include/asm directory. This patch gives the arch/$ARCH/include/asm directory priority over include/asm. When we add asm-offsets.h to arch/$ARCH/include/asm/ this patch makes sure we pick up the arch specific version and not the one we have in include/asm. The situation with an asm-offsets.h file located in both include/asm _and_ arch/$ARCH/include/asm will happen when we move more files over to include/generated. This happens because in some cases it is not practical to rename all users so we simply add a file in arch/$ARCH/include/asm that includes the generated version.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the user has an older version of objcopy, that can not handle converting local symbols to global and vice versa, then some functions will not be part of the dynamic function tracer. The current code in recordmcount.pl will print a warning in this case. Unfortunately, there exists lots of files that may have this issue with older objcopys and this will cause a warning for every file compiled with this issue. This patch solves this overwhelming output by creating a .tmp_quiet_recordmcount file on the first instance the warning is encountered. The warning will not print if this file exists. The temp file is deleted at the beginning of the compile to ensure that the warning will happen once again on new compiles (because the issue is still present).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that all host programs use static for all private functions and forward prototypes for all extern functions, add -Wmissing-prototypes to HOSTCFLAGS in the hopes of keeping it that way. All versions of GCC supported by the kernel handle -Wmissing-prototypes. Signed-off-by: Josh Triplett <josh@joshtriplett.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Revert commit 575543347b5baed0ca927cb90ba8807396fe9cc9 It caused following issues: - On architectures where ARCH= setting is used to select between 32 and 64 bit this was no longer possible without "make mrproper" - If ARCH was changed then kbuild refused to run "make mrproper" because ARCH had changed - When CROSS_COMPILE was changed people were asked to run "make mrproper" but kbuild refused to run "make mrproper" because CROSS_COMPILE changed. - Spaces in CROSS_COMPILE was not 'supported' - If an non-existing ARCH= was used kbuild could get stuck Lessons learned: . Despite being simple and straghtforward people uses very different approaches when building the kernel. . CROSS_COMPILE is sometimes used for ccache despite cache being only a CC frontend so one would have expected CC to be used for this purpose. . And obviously this was not tested widely enough.
