* Remove the Xtensa architectureThomas Petazzoni2012-09-201-40/+0
| | | | | | | | | | | | | | As stated in commit 555c2585bf28c3ef71f6d2dcdd983d17a19892af, the Xtensa architecture has been introduced in 2009 and never changed since its initial introduction. It requires some special handling that is a bit annoying, and despite our call to the initial developers, and the announcement of the deprecation of the architecture during the 2012.05, nothing has happened. Therefore, drop support for this architecture. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Acked-by: me Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
* Move BR2_SPARC_TYPE to an uClibc specific placeThomas Petazzoni2012-09-201-5/+0

* Move BR2_ARM_TYPE to an uClibc specific placeThomas Petazzoni2012-09-201-21/+0
| | | | | | | | | | | | | | BR2_ARM_TYPE is a hidden configuration option that is only used for the configuration of uClibc, therefore, we move it from target/Config.arch.in to toolchain/uClibc/Config.in. We also add a comment that explains that this stuff is only useful for uClibc <= 0.9.32. Starting from 0.9.33, uClibc build process simply uses the compiler flags to find the ARM processor that should be used. So, someday, we'll be able to remove this.

* Clarify MIPS ABIs supportThomas Petazzoni2012-09-041-25/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Simplify x86 target architecture variant handlingThomas Petazzoni2012-07-311-78/+35
| | | | | | | | | | Instead of having two separate list of choices for select the target architecture variant for i386 and x86_64, with many CPU choices duplicated (because all modern x86 CPUs can be both used as i386 or x86_64), merge them into a single list. In the x86_64 case, all the x86 CPUs that do not support the 64 bits instruction set are hidden. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

* blackfin: adjust available ABIsThomas Petazzoni2012-05-091-5/+2
| | | | | | | | | | | | | | | | | | | The FLAT (Separate Data) and FLAT Shared ABIs are rarely used, and the FLAT Shared ABI requires the user to manually assign an unique ID to each shared library, which we will never support in Buildroot. Therefore, restrict ourselves to FLAT and FDPIC. In addition to this, ensure that when FLAT is selected, only static libraries are produced, because this is what FLAT supports. It will fix problems such as http://autobuild.buildroot.org/results/2d756d75162e8737e99df8189bde93ed1a09feef/build-end.log. Moreover, we make FDPIC the default ABI, since if someone is using Buildroot, it's most likely to generate a fairly elaborate embedded Linux system, on which shared libraries are probably useful.

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.

* Create <tuple>/lib -> <sysroot>/lib symlink before installing cross gccThomas Petazzoni2010-07-271-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit solves bug #1051. The problem in this bug in that WebKit compiles a sample C program, which uses WebKit. As WebKit is written in C++, even though the program it built with CROSS-gcc, it must be linked with libstdc++. However, CROSS-gcc can't find the libstdc++ has it's hidden inside <sysroot>/<tuple>/lib. Therefore, this commit creates a symbolic link <sysroot>/<tuple>/lib -> <sysroot>/lib before running the CROSS-gcc installation. While this may look like a hack, this is the solution used by both Crosstool-NG and OpenWRT. Moreover, with this symbolic link in place, I think bug #1741 may also be solved. The problem in this bug is that the linker tries to link against /lib/libc.so.0. This is due to the fact that the linker finds a libc.so script file in the original toolchain location and not inside the copy of the toolchain sysroot in $(STAGING_DIR). As the script file is found outside of the current toolchain sysroot, ld considers the script has non-sysrooted, and therefore doesn't prefix all paths found in the script file (such as /lib/libc.so.0) with the sysroot path, leading to the failure. So, in details, this commit : * Adds a BR2_ARCH_IS_64 invisible config knob that is used to know if the arch is a 64 bits architecture or not. * Creates the <sysroot>/<tuple>/lib -> <sysroot>/lib symbolic link, and the <sysroot>/<tuple>/lib64 -> <sysroot>/lib64 symbolic link if needed. * Fixes the external toolchain sysroot detection code so that the 'sed' replacement is done *after* the readlink -f evaluation. I have tested this by building ARM, x86 and x86_64 toolchains with Buildroot, and then use these toolchains as external toolchains to build a full X.org/Gtk/WebKit/Midori stack. I have also done a complete ARM Buildroot internal toolchain build with the same full X.org/Gtk/WebKit/Midori stack. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
