toolchain: add coldfire support

2016-04-30T16:50:46+00:00

Add support for m68k/coldfire. A gcc patch is required to avoid gcc ICE. Signed-off-by: Waldemar Brodkorb Signed-off-by: Thomas Petazzoni

uclibc/defconfig: enable XSI math

2016-04-23T09:40:00+00:00

ARM926 size delta +12 KB. It's required for the upcoming mpv package. Signed-off-by: Gustavo Zacarias Signed-off-by: Peter Korsgaard

arch/x86: remove support for i386

2016-04-18T21:38:34+00:00

The Linux kernel doesn't even support i386 anymore, there is no NPTL support for i386 and uClibc-ng only supports NPTL on x86, so there is essentially no usable thread implementation. Most likely glibc and musl also don't support i386 either. So it's time to remove the support for this architecture variant.

uclibc: context functions are not Thumb-compatible

2016-04-08T08:20:37+00:00

The context functions in uClibc unconditionally use the classic ARM instruction set. On platforms that do support the ARM instruction set, there is no problem - However, on platforms that only support the Thumb instruction set, the context functions cannot be built since the assembler code is not Thumb-ready. Therefore, these functions must be disabled on such platforms. All Thumb1 platforms support ARM instructions, so this is only relevant for Thumb2-only platforms (i.e., Cortex-M). Note that some packages require the context functions, so these will fail to build on these platforms. It is worth mentioning that musl also doesn't provide the context functions, and those are rarely used. Affected packages will be handled in later patches.

uclibc: use upstreamed patch for ARM Thumb simplification

2016-04-08T08:19:46+00:00

The uClibc patches to simplify the ARM Thumb configuration options have been merged, but instead of being 5 separate patches, they have been merged as a single patch. This commit updates the Buildroot uClibc package to use the patch that was actually upstreamed. Signed-off-by: Thomas Petazzoni Signed-off-by: Peter Korsgaard

uclibc: enable linuxthreads for xtensa

2016-03-31T01:56:32+00:00

linuxthreads is the only threading option for noMMU xtensa, enable it. Signed-off-by: Max Filippov Signed-off-by: Thomas Petazzoni

uclibc: NPTL thread implementation only available on MMU platforms

2016-03-29T22:23:00+00:00

As indicated by the uClibc-ng source code, the NPTL thread implementation is only available on MMU platforms, so we replicate this dependency in Buildroot so that the appropriate thread implementation is chosen by default on ARM noMMU.

uclibc: disable DOPIC on ARM FLAT

2016-03-29T22:15:48+00:00

As explained by Waldemar, enabling DOPIC in uClibc will lead to the creation of a Position Independent library. In turn, this will cause elf2flt to generate a "Has-PIC-GOT" flat binary, which doesn't work on ARM. In fact, elf2flt on ARM really expect to have non-PIC code as input, so we must disable DOPIC in the uClibc configuration.

uclibc: gcc >= 4.9 can build a thumb/thread uclibc

2016-03-29T22:15:14+00:00

Older gcc were not capable of building a uClibc library, with threads enabled, in Thumb1. However, the issues have been fixed since gcc 4.9, so this commit narrows down the condition to just gcc 4.7 and 4.8.
