2012-01-07toolchain: add powerpc SPE ABI supportGustavo Zacarias
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.

2011-07-18sh: Fix Buildroot sh targets to match gnuconfig targetsPhil Edworthy
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. To build for devices without an fpu, the relevant toolchain flags will have to be specified.

2010-08-31Remove architectures marked as deprecatedThomas Petazzoni
The Alpha, CRIS, IA64 and Sparc64 architectures have been marked as deprecated during the previous release cycle. They are not widely used in embedded systems and/or no longer supported by their manufacturers and/or not properly supported in Buildroot. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
2010-08-11Mark CRIS architecture as deprecatedThomas Petazzoni
The CRIS architecture support in Buildroot hasn't been updated since a long time. Even a toolchain with recent kernel headers does not build due to missing patches. Moreover, the CRIS architecture has been discontinued by Axis, as visible at http://www.axis.com/products/dev/index.htm. We will remove it from Buildroot at the next release cycle.

2010-07-27Deprecate the Alpha, IA64 and Sparc64 supportThomas Petazzoni
Those architectures don't exist anymore (Alpha, IA64) or aren't widely used for embedded systems running Linux. Moreover, no clear Buildroot maintainer has stepped in to maintain these architectures, so it's better to not pretend that we support them. The goal is to mark them as deprecated in 2010.08 and remove them in 2010.11. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
2010-07-27Create <tuple>/lib -> <sysroot>/lib symlink before installing cross gccThomas Petazzoni
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>
