toolchain/buildroot: not available for a few mips cores

2017-08-29T21:18:56+00:00

Commit 1b974425 (MIPS: add support for M6201 cores) explained that the new core was not supported by upstream gcc, and as of gcc-8-trunk that's still the case. Ditto for 3cfbeb83 (MIPS: add support for P6600 cores). This means that we currently allow to build an internal tolchain for those cores, yet we have no suitable gcc version. Disable the internal backend in this case. Signed-off-by: "Yann E. MORIN" Cc: Vicente Olivert Riera Cc: Thomas Petazzoni Signed-off-by: Thomas Petazzoni

toolchain: introduce BR2_TOOLCHAIN_HAS_FULL_GETTEXT

2017-07-04T17:09:50+00:00

This new boolean is true if the toolchain provides a built-in full-featured implementation of gettext (glibc), and false if only a stub implementation is provided (uclibc, musl). This will be used in follow-up commits to decide whether libintl needs to be built by gettext or not.

toolchain: disable PIE for static build with musl

2017-05-23T13:36:08+00:00

As mentioned in commit 3c93901bcd2 (toolchain: add hidden symbol for PIE support), support for static PIE using musl requires a gcc patch[1]. Buildroot doesn't carry this patch. Don't enable BR2_TOOLCHAIN_SUPPORTS_PIE in static build with musl.

arch: add support for the csky architecture

bfin: change default to bf532, internal toolchain !bf6xx

2016-08-27T21:07:11+00:00

The default Blackfin processor in Buildroot isn't supported by gcc 6.1.0, so use bf532 as default. Disable any bf6xx processors for internal toolchain users. Signed-off-by: Waldemar Brodkorb Signed-off-by: Thomas Petazzoni

uclibc: disable PIE for microblaze

PIE is not supported at the moment for uClibc-ng/microblaze. Fixes: http://autobuild.buildroot.net/results/a5848753eb0e2b0ddf55e226c45b85fd3a1c84f3/ Signed-off-by: Waldemar Brodkorb Signed-off-by: Thomas Petazzoni

toolchain: Bump ARC tools to arc-2016.09-eng007 and enable PIE

2016-08-01T20:59:31+00:00

As described at: 4520524ba055706236db9f00dd79f1b2e2e87fde this commit continues a series of updates of ARC tools. This time we're updating tools to arc-2016.09-eng007 tag plus a couple of fixes on top of it that will all make its way in the next engineering build. We hope this patch will cure most buildroot ARC failures as it contains important fixes: 1) PIE fix. We have added PIE support to ARC toolchain at last. So that should prevent breakage of many packages. As ARC now supports PIE we remove ARC from BR2_TOOLCHAIN_SUPPORTS_PIE exclusion in toolchain/Config.in file. 2) Assembler fix. This patch also have changes that fixes frequent assembler failures, e.g.: http://autobuild.buildroot.net/results/543/5430b902d900943a34c1888e7e410bd5df367bc2// We still keep GDB as it is of arc-2016.03 release because there're some issues we'd like to resolve before releasing it to wider audience. So again note this is next engineering builds of arc-2016.09 series and it might have all kinds of breakages, please don't use it for production builds.

toolchain: add hidden symbol for PIE support

2016-07-24T19:44:22+00:00

uClibc-ng does not support PIE for some architectures as arc and m68k. It isn't implemented in the static linking case, too. With musl toolchains you might have static PIE support with little patching of gcc. Static linking for GNU libc isn't enabled in buildroot. Fixup any package using special treatment of PIE.

toolchain-buildroot: add bfin support

2016-07-04T09:00:15+00:00

With gcc 6.1.0 and binutils 2.26 internal bfin toolchain can be used. A gcc patch is required, which was reported upstream. Signed-off-by: Waldemar Brodkorb Signed-off-by: Thomas Petazzoni

toolchain: improve SSP logic

2016-05-23T19:07:24+00:00

Don't enable SSP support on external toolchains just because they use glibc or musl. Instead of that, make the external toolchains explictily declare if they support SSP or not. And also add a check to detect SSP support when using custom external toolchains. For internal toolchains we always enable SSP support for glibc and musl.
