Subject: kbuild updates
Date: Fri, 13 Aug 2004 21:28:04 +0200 [thread overview]
Message-ID: <20040813192804.GA10486@mars.ravnborg.org> (raw)
This is the accumulated list of kbuild patches.
Mostly trivial stuff but also a bit of interest:
o replaced host-progs with hostprogs-y
o Use a shell script to generate System.map
Includes check for undefined symbols in vmlinux
Filter out __crc_ from System.map
-> This replaces two other patches in -mm
- rmk's ldchk function
- wli btfixup patch, number 13 in his serie
This patch replaces both
o Randy's patch to put version in .config
o One patch to a few files so we use POSIX header in some of the
tools.
This is a slow start on improving the build on non-linux platforms.
This does in no way clear my kbuild queue - but the rest
is put on hold for a while.
Everything pushed to:
bk://linux-sam.bkbits.net/kbuild
When the patches has been in -mm for a while they will be pushed
to Linus.
None of this is pre 2.6.8 material.
Patches will follow in seperate mails.
Sam

kbuild: __crc_* symbols in System.map
David S. Miller <davem@redhat.com> wrote:
Shouldn't we be grepping __crc_ symbols out of the System.map file?
For one thing, these can confuse readprofile. It's algorithm is
to start at _stext, then stop when it sees a line in the System.map
which is not text (mode is one of 'T' 't' 'W' or 'w')
It will exit early if there are some intermixed __crc_* things in
there (since they are are mode 'A').
For example, in my current sparc64 kernel I have this:
00000000004cef80 t do_split
00000000004cf2a0 t add_dirent_to_buf
00000000004cf5a7 A __crc_init_special_inode
00000000004cf640 t make_indexed_dir
00000000004cf900 t ext3_add_entry
So no symbols after add_dirent_to_buf will be shown in the profiling
output of readprofile.
Implementation ported to mksysmap by Sam.
Included two System.map related fixes:
- Print "SYSMAP System.map" during build
- Sort symbols in System.map

kbuild: Use POSIX headers for ntoh functions
From: Benno <benjl@cse.unsw.edu.au>
When compiling Linux on Mac OSX I had trouble with scripts/sumversion.c.
It includes <netinet/in.h> to obtain to definitions of htonl and ntohl.
On Mac OSX these are found in <arpa/inet.h>. After checking the POSIX
specification it appears that this is the correct place to get
the definitons for these functions.
(http://www.opengroup.org/onlinepubs/009695399/functions/htonl.html)
Using this header also appears to work on Linux (at least with
Glibc-2.3.2).
It seems clearer to me to go with the POSIX standard than implementing
#if __APPLE__ style macros, but if such an approach is preferred I can
supply patches for that instead.

kbuild: Fix hostprogs-y
Allow the same target to be specified more than once without causing a warnign from make.
The same target may be specified twice when using the following pattern:
hostprogs-$(CONFIG_FOO) += program
hostprogs-$(CONFIG_BAR) += program

<sam@mars.ravnborg.org> (04/08/10 1.1908)
kbuild: Introduce hostprogs-y, deprecate host-progs
Introducing hostprogs-y allows a user to use the typical Kbuild
pattern in a Kbuild file:
hostprogs-$(CONFIG_KALLSYMS) += ...
And then during cleaning the referenced file are still deleted.
Deprecate the old host-progs assignment but kept the functionlity.
External modules will continue to use host-progs for a while - drawback is
that they now see a warning.
Workaround - just assign both variables:
hostprogs-y := foo
host-progs := $(hostprogs-y)
All in-kernel users will be converted in next patch.

kbuild: Separate out host-progs handling
Concentrating all host-progs functionality in one file made a more
readable Makefile.lib - and allow for potential reuse of host-progs
functionality.
Processing of host-progs related stuff are avoided when no host-progs are specified.

kbuild: Accept absolute paths in clean-files and introduce clean-dirs
Teach kbuild to accept absolute paths in clean-files. This avoids using
clean-rules in several places.
Introduced clean-dirs to delete complete directories.
Kept clean-rule - but do not print anything when used.
Cleaned up a few places now the infrastructure are improved.

kbuild: Use LINUXINCLUDE to specify include/ directory
Peter Chubb <peterc@gelato.unsw.edu.au> reported that building i386
on a non-i386 platform failed, because gcc could not locate boot.h.
Root cause was the extra include2 directory used when using O=
to specify the output directory.
Added LINUXINCLUDE as a portable way to specify the include/
directory, and changed the two users.
This avoids hardcoding 'include2' in non-kbuild core files.

kbuild/sparc: Use new generic mksysmap script to generate System.map
o Introduced usage of the mksysmap script.
o Improved the non-verbose output to look like this:
BTFIX arch/sparc/boot/btfix.S
AS arch/sparc/boot/btfix.o
LD arch/sparc/boot/image
SYSMAP arch/sparc/boot/System.map
o No longer generate System.map for each build
o Use normal AS rule to compile btfix.S

kbuild: Check for undefined symbols in vmlinux
At least one bin-utils version for ARM is know to ignore undefined
symbols when performing the final link of vmlinux.
Add an explicit check for undefined symbols to catch this.
The check is made in combination with generating the System.map file
and the actual algorithm is moved to a small shell script - mksysmap.
External symbols with three leading underscores are ignored - sparc
uses them for the BTFIXUP logic.
