arch/bfin: internal backend not suitable for some cores

2017-10-02T19:41:53+00:00

Some cores are not supported by upstream gcc. Use the newly-introduced symbol to state so, rather than have the exclusion in the toolchain choice. Signed-off-by: "Yann E. MORIN" Cc: Thomas Petazzoni Cc: Arnout Vandecappelle Signed-off-by: Thomas Petazzoni

arch/csky: internal backend not suitable

2017-10-02T19:41:36+00:00

Upstream gcc does not have support for C-Sky, and we do not have a vendor tree for it either (yet?). Use the newly-introduced symbol to state so, rather than have the exclusion in the toolchain choice. Signed-off-by: "Yann E.

arch: add option to disable internal toolchain backend

2017-10-02T19:41:29+00:00

Some architectures or specific cores do not have support in upstream gcc. Currently, they are individually listed as exclusions in the toolchain choice. This poses a maintainance burden, as the knowledge about what gcc version supports what architecture is split across many places: the toolchain choice, the gcc version choice, the external toolchains. As a first step, add a blind option that architectures or individual cores may select to indicate they lack support in our internal backend. Actual use of the option will come in followup patches.

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.

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
