* Clarify MIPS ABIs supportThomas Petazzoni2012-09-041-4/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Practically speaking, MIPS has three useful ABIs: * o32 is for 32-bits CPUs, or 64-bit CPUs running only a 32-bit subset of the instruction set. * n32 is for 64-bits CPUs only. It has 32-bits pointers and long integers. * n64 is for 64-bits CPUs only. It has 64-bits pointers and long integers. See http://www.linux-mips.org/wiki/MIPS_ABI_History and http://www.linux-mips.org/wiki/WhatsWrongWithO32N32N64 for more details. So, this commit reworks the Buildroot MIPS support by: * Add separate mips64/mips64el top-level architectures. * Renaming the n32 ABI option to BR2_MIPS_NABI32, for consistency with BR2_MIPS_OABI32. * Renaming the n64 ABI option to BR2_MIPS_NABI64, for consistency with BR2_MIPS_OABI32. * Make the n32 and n64 ABI selections select the BR2_ARCH_IS_64, since those ABIs are valid on 64-bits CPUs only. * Removing the o64 ABI, which is practicaly never used. * Removing the "none" ABI, which really doesn't make sense. * Introduce the mips64 and mips64el architecture names when a 64-bits MIPS ABI is choosen. This will fix build issue like http://autobuild.buildroot.org/results/9b8c5ea86c953a89e85e7b67e9221de41773f652/build-end.log where gmp was confused by the fact of having a 32 bits architecture (detected by the mips- architecture part of the tuple) but 64 bits integer size when compiling. * Adjust the uclibc.mk logic to support the new mips64/mips64el architecture names, and take into account the renaming of the ABI options. This has been build tested by generating Buildroot toolchains and compiling a few packages for MIPS o32, MIPS n32 and MIPS n64. This work is originally based on prior work done by Gustavo Zacarias.

* toolchain/mips: kill EABI and fix N32Gustavo Zacarias2012-07-151-1/+1
| | | | | | | | | MIPS EABI is a bare-metal ABI so remove it. Also fix uClibc to really work with N32 ABI, which used the EABI knob previously. Signed-off-by: Gustavo Zacarias <gustavo@zacarias.com.ar> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

* Add support to generate locale dataThomas Petazzoni2012-05-091-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to use locale support on a Linux system, you need locale data to be present: * on a (e)glibc based system, this data is typically in the /usr/lib/locale/locale-archive file, which can be created and extended using the localedef program * on an uClibc based system, the set of supported locales is defined at build time by an uClibc configuration option. This patch implements generating locale data for the following cases: * Internal toolchain * External toolchain based on (e)glibc. uClibc external toolchains are not supported, because with uClibc, the set of supported locales is defined at build time. CodeSourcery and Linaro toolchains have been tested, Crosstool-NG toolchains are believed to work properly as well. * Toolchains built using the Crosstool-NG backend, but only (e)glibc toolchains. This feature was runtime tested with internal uClibc toolchain, CodeSourcery ARM toolchain and Linaro ARM toolchain, thanks to a simple C program that shows the data and a gettext translated message. Note that this option differs from the "purge locales" option, which is responsible for removing translation files and other locale stuff installed by packages. At some point in the future, we may want to clarify the respective roles of those options.

* DOWNLOAD: change $1=DIRECTORY_URL, $2=FILE_NAME to $1=FULL_FILE_URL, ↵Alvaro G. M2012-03-181-1/+1
| | | | | | | | | | | | | | | | | | | | | $2=FILE_NAME This modifies the definition of DOWNLOAD to receive two arguments: the first one is the full URL of the file to download, whereas the second (and optional) is the name the file will have once downloaded. Same thing with the SOURCE_CHECK_WGET and SCP functions. All calls to these functions have been changed to the shortest form of the new API, except for toolchains acquisition. Since there is quite a number of different toolchains this call to DOWNLOAD is better set to the generic one. Signed-off-by: Alvaro G.

* toolchain: add powerpc SPE ABI supportGustavo Zacarias2012-01-071-1/+7
| | | | | | | | | | | | | | | | | Add the ability for buildroot to build an SPE ABI enabled toolchain. This is mandatory for e500v1/v2 cores since they don't support classic FPU mode as the e500mc does. Useful for Freescale's PowerQUICC III and single/dual-core QorIQ line of processors. The new TARGET_ABI variable is used rather than TARGET_CFLAGS for uclibc's UCLIBC_EXTRA_CFLAGS to avoid breakish CFLAGS leaking in, a good example being -mthumb for ARM.

* support: move patch-kernel.sh and rename itThomas Petazzoni2011-09-171-2/+2

* uClibc: drop BR2_PROGRAM_INVOCATION optionPeter Korsgaard2011-07-271-7/+0
| | | | | | | | | | | | Remove the BR option and enable the configuration setting in the uClibc defconfigs. The BR2_PROGRAM_INVOCATION option only adds very little overhead to uClibc, and we have a number of packages needing it, so simply always enable it - Simplifying the kconfig logic and the number of choices users have to make.

| | | | | | | | | | | | | | sh2eb and sh2a_nofpueb gnuconfig targets are no longer supported in Buildroot. This patch replaces these Buildroot targets with sh2 and sh2a respectively, and adds sh4a targets as these are widely used.

* toolchain: move Stack Protection Support optionThomas Petazzoni2010-12-131-1/+1
| | | | | | | | | | The BR2_USE_SSP option is only used inside the uClibc build, so only meaningful for Buildroot internal toolchains.

* Add support for uclibc NPTL toolchain.Khem Raj2010-07-291-5/+10
| | | | | | | | | | | | | | | | | | | | This patch modifies current toolchain build sequence so that NPTL enabled toolchain can be built. The new sequence works well with linuxthreads as well. It introduces a new pass for gcc cross compilation. The new sequence is binutils->gcc-initial->linux-headers -> uclibc-configured (some cheats to generate phony shared libc.so and libm.o) -> gcc-intermediate(with shared lib support) -> uclibc -> gcc-final I also added a new sample config arm_nptl_toolchain_defconfig which builds the toolchain and busybox. I have only tried it on arm. However it should work for other architectures which support NPTL on uclibc e.g. mips, sh, x86, ppc, x86_64 Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

* uclibc: make sure the default configuration doesn't ask questionsThomas Petazzoni2010-05-021-1/+3
| | | | | | | | | | | | | Since new configuration options have been added in 0.9.31, the value of these configuration options should be determined, either by the default configuration file we provide, or by uclibc.mk process. The locale generation process should probably be improved in order to allow building other locales than just en_US.

* Fix PROGRAM_INVOCATION handling with external toolchainsThomas Petazzoni2009-07-311-1/+1
| | | | | | | | | | | | | BR2_UCLIBC_PROGRAM_INVOCATION is a toolchain configuration option, like BR2_INET_IPV6, BR2_INET_RPC, on which some packages depend. Therefore, it should be handled like BR2_INET_IPV6 and BR2_INET_RPC in order to work properly with external toolchains. Since we move it out of toolchain/uClibc/Config.in into toolchain/Config.in.2, we rename the option to BR2_PROGRAM_INVOCATION (since BR2_INET_RPC and others don't have UCLIBC in their name).
