* Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>
* Rename TEXT_BASE into CONFIG_SYS_TEXT_BASEWolfgang Denk2010-10-18-5/+5
| | | | | | | | | | | | The change is currently needed to be able to remove the board configuration scripting from the top level Makefile and replace it by a simple, table driven script. Moving this configuration setting into the "CONFIG_*" name space is also desirable because it is needed if we ever should move forward to a Kconfig driven configuration system.

* config.mk: avoid -traditional-cpp on OS X 10.5Mike Frysinger2010-08-09-5/+5
| | | | | | | | | | | | | | | | | Simply trying to include a basic header file like stdlib.h on OS X 10.5 and then building with -traditional-cpp fails with lots of errors like: In file included from /usr/include/stdlib.h:63, from test.c:3: /usr/include/available.h:85: error: stray '#' in program /usr/include/available.h:85: error: syntax error before numeric constant /usr/include/available.h:86: error: stray '#' in program In the past, I hadn't noticed because the old logic for these flags were restricted to Darwin running on PowerPC systems while I'm running on an Intel system. But after some recent clean ups and changes, the flag was being applied to all Darwin systems and my host tools broke. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* config.mk: use different host compiler for OS X 10.6Andreas Biessmann2010-05-26-3/+11
| | | | | | | | | | | | | | | | Compiling tools subdirectory on Mac OS X 10.6 (Snow Leopard) complains about wrong syntax in system includes.

* Change directory-specific CFLAGS to use full pathPeter Tyser2010-04-13-6/+11
| | | | | | | | | | | | | | | | | | Previously, a specific file or directory could be compiled with custom CFLAGS by adding a Makefile variable such as: CFLAGS_dlmalloc.o = <custom flags for common/dlmalloc.c> or CFLAGS_lib = <custom flags for lib directory> This method breaks down once multiple files or directories share the same path. Eg FLAGS_fileA = <custom flags> would incorrectly result in both dir1/fileA.c and dir2/fileA.c being compiled with <custom flags>. This change allows finer grained control which we need once we move lib_$ARCH to arch/$ARCH/lib/ and lib_generic/ to lib/. Without this change all lib/ directories would share the same custom CFLAGS.

* Create CPUDIR variablePeter Tyser2010-04-13-6/+7
| | | | | | | | | | | | The CPUDIR variable points to the location of a target's CPU directory. Currently, it is set to cpu/$CPU. However, using $CPUDIR will allow for more flexibility in the future. It lays the groundwork for reorganizing U-Boot's directory structure to support a layout such as: arch/$ARCH/cpu/$CPU/* (architecture with multiple CPU types) arch/$ARCH/cpu/* (architecture with one CPU type) Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
* makefiles: fixes for building build toolsScott Wood2009-12-02-3/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, some of the tools instead set CC to be HOSTCC in order to re-use some pattern rules -- but this fails when the user overrides CC on the make command line. Also, the HOSTCFLAGS in tools/Makefile are currently not being used because config.mk overwrites them. This patch adds static pattern rules for files that have been requested to be built with the native compiler using $(HOSTSRCS) and $(HOSTOBJS), and converts the tools to use them. It restores easylogo to using the host compiler, which was broken by commit 38d299c2db81bd889c601b5dfc12c4e83ef83333 (if this was an intentional change, please let me know -- but it seems to be a build tool). It restores -pedantic and the special flags for darwin and cygwin that were requested in tools/makefile (but keeps the flags added by config.mk) -- hopefully someone can test this on those platforms. It no longer conditionalizes -pedantic on not being darwin; it wasn't clear that that was intentional, and unless there's a real problem it's just inviting people to contribute non-pedantic patches to those files (I'm not a fan of -pedantic personally, but if it's on for one platform it should be on for all). HOST_LDFLAGS is renamed HOSTLDFLAGS for consistency with the previous HOST_CFLAGS to HOSTCFLAGS rename. A new HOSTCFLAGS_NOPED is made available for those files which currently cannot be built with -pedantic, and replaces the old FIT_CFLAGS. imls now uses the cross compiler properly, rather than by trying to reconstruct CC using the typoed $(CROSS_COMPILER). envcrc.c is now dependency-processed unconditionally -- previously it would be built without being on (HOST)SRCS if CONFIG_ENV_IS_EMBEDDED was not selected.

| | | | | | | | | | Some board ports place TEXT_BASE at a location that would cause the RESET_VECTOR_ADDRESS not to be at 0xfffffffc when we link.

* start a linker script helper fileMike Frysinger2009-08-23-10/+0
| | | | | | | | | | | | | | | Start a common header file for common linker script code (such as workarounds for older linkers) rather than doing this in the build system. As fallout, we no longer execute the linker every time config.mk is included by a build file (which can easily be 70+ times), but rather only execute it once. This also fixes a bug in the major version checking by creating a macro to easily compare versions and keep people from making the same common mistake (forgetting to check major and minor together).

* Fix all linker scripts for older binutils versions (pre-2.16)Wolfgang Denk2009-08-21-1/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit f62fb99941c6 fixed handling of all rodata sections by using a wildcard combined with calls to ld's builtin functions SORT_BY_ALIGNMENT() and SORT_BY_NAME(). Unfortunately these functions were only introduced with biunutils version 2.16, so the modification broke building with all tool chains using older binutils. This patch makes it work again. This is done by omitting the use of these functions for such old tool chains. This will result in slightly larger target binaries, as the rodata sections are no longer in optimal order alignment-wise which reauls in unused gaps, but the effect was found to be insignificant - especially compared to the fact that you cannot build U-Boot at all in the current state. As ld seems to have no support for conditionals we run the linker script through the C preprocessor which can be easily used to remove the unwanted function calls. Note that the C preprocessor must be run with the "-ansi" (or a "-std=") option to make sure all the system-specific predefined macros outside the reserved namespace are suppressed. Otherise, cpp might for example substitute "powerpc" to "1", thus corrupting for example "OUTPUT_ARCH(powerpc)" etc. Signed-off-by: Wolfgang Denk <wd@denx.de> Cc: Mike Frysinger <vapier@gentoo.org>
* ARM: compiler options cleanup - improve tool chain supportWolfgang Denk2009-08-21-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For some time there have been repeated reports about build problems with some ARM (cross) tool chains. Especially issues about (in)compatibility with the tool chain provided runtime support library libgcc.a caused to add and support a private implementation of such runtime support code in U-Boot. A closer look at the code indicated that some of these issues are actually home-made. This patch attempts to clean up some of the most obvious problems and make building of U-Boot with different tool chains easier: - Even though all ARM systems basicy used the same compiler options to select a specific ABI from the tool chain, the code for this was distributed over all cpu/*/config.mk files. We move this one level up into lib_arm/config.mk instead. - So far, we only checked if "-mapcs-32" was supported by the tool chain; if yes, this was used, if not, "-mabi=apcs-gnu" was selected, no matter if the tool chain actually understood this option. There was no support for EABI conformant tool chains. This patch implements the following logic: 1) If the tool chain supports "-mabi=aapcs-linux -mno-thumb-interwork" we use these options (EABI conformant tool chain). 2) Otherwise, we check first if "-mapcs-32" is supported, and then check for "-mabi=apcs-gnu" If one test succeeds, we use the first found option. 3) In case 2), we also test if "-mno-thumb-interwork", and use this if the test succeeds. [For "-mabi=aapcs-linux" we set "-mno-thumb-interwork" mandatorily.] This way we use a similar logic for the compile options as the Linux kernel does. - Some EABI conformant tool chains cause external references to utility functions like raise(); such functions are provided in the new file lib_arm/eabi_compat.c Note that lib_arm/config.mk gets parsed several times, so we must make sure to add eabi_compat.o only once to the linker list.

PCI_66M is automatically configured via $(BOARD)_config names with the help of $(findstring _66_,$@). * Unfortunately $(PCI_CLOCK) has been undocumented anywhere, so only a few people know the existence of it these days. * Keep config.mk independent from $(BOARD) as much as possible.

* allow boards to customize compiler options on a per-file/dir basisMike Frysinger2009-06-14-3/+5
| | | | | | | | | | | | | | With our Blackfin boards, we like to build the compression routines with -O2 as our tests show a pretty good size/speed tradeoff. For the rest of U-Boot though, we want to stick with the default -Os as that is mostly control code. So in our case, we would add a line like so to the board specific config.mk file: CFLAGS_lib_generic += -O2 Now all files under lib_generic/ will have -O2 appended to their build.

| | | | | | | | | | | | | | | | | | | | When compile-testing on powerpc, I get errors like this: net/nfs.c:422: undefined reference to `__stack_chk_fail_local' This seems to be because -fstack-protector is on by default, so let's explicitly disable it on all architectures that support the option. The Ubuntu toolchain is affected by this problem, and according to Mike Frysinger, Gentoo has been running with SSP enabled for years. More and more distros are turning SSP on by default, so this problem is likely to get worse in the future. Also, powerpc just happens to be one of the arches I do compile-testing on. There may be other arches affected by this too. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
