pixman: properly enable/disable ARM optimizations

2016-08-27T12:44:05+00:00

The pixman ARM optimized code assumes that ARM instructions are available. Unfortunately, the configure.ac checks do not detect that the platform is Thumb-only for Cortex-M builds, so it enables the ARM optimizations, leading to failures like: error: /home/test/autobuild/run/instance-3/output/host/usr/arm-buildroot-uclinux-uclibcgnueabi/sysroot/usr/lib/libpixman-1.a(pixman-arm-simd-asm-scaled.o): Conflicting CPU architectures 13/1 When building programs linked with pixman on Thumb-only architectures. This is due to the fact that some object files in libpixman-1.a are built for the ARM instruction set. To resolve this, we give better hints to the pixman configure script about which ARM optimizations to use: the ARM SIMD optimizations need at least a CPU that supports ARM instructions, and obviously the ARM NEON optimizations need NEON support.

toolchain-external: remove Sourcery PowerPC toolchains

2016-05-01T13:05:34+00:00

These are running long on the teeth - the bundled (e)glibc versions are very old with several security bugs, they don't work reliably with -Os and have several build failures related to internal compiler errors such as: http://autobuild.buildroot.net/results/fe7/fe7bdba5faf199275aedea2918705b5d19d228bf/ http://autobuild.buildroot.net/results/935/935ac42c30ed893939c06c077534f060aed80e9a/ http://autobuild.buildroot.net/results/a47/a476af82c8fe4a279117314b278b08af9a08fe54/ http://autobuild.buildroot.net/results/cae/cae720b5096be2672b4dc1311ae3fc4ed06a3b53/ The situation will not provide, and will in fact get worse with older kernel headers precluding modern package versions and the old gcc version doing as well so remove them.

pixman: add patch to fix build issue with musl

2016-01-27T22:49:19+00:00

pixman fails to build with musl because is included in assembler files, which doesn't work with the provided by musl. This commit fixes that by patching pixman (patch submitted upstream). Reported-by: Eial Czerwacki Signed-off-by: Thomas Petazzoni

toolchain-external: CodeSourcery PowerPC: Revert the removal of CS PowerPC 2011.03

2015-12-30T21:25:50+00:00

As reported by Yann E. MORIN [1], the latest CS PowerPC toolchain (2012.03) requires a PPC CPU with SPE, which is basically two variants, 8540 (e500v1) and 8548 (e500v2) in Buildroot. All other PPC CPU can't use that toolchain. Keep CS PowerPC 2011.03 as latest available version and add a second Kconfig symbol for the CS PowerPC 2012.03 since it's verry specific to one CPU type (e500v2). Previously it was possible to select the CS 2012.03 with a powerpc 8540 (e500v1) CPU but the sysroot provided by the toolchain only support the 8548 (e500v2) variant. Allow to select CS 2012.03 only with BR2_powerpc_8548. Also re-add the previous CS toolchain handling for pixman and liquid-dsp.
