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. Fixes: http://autobuild.buildroot.net/results/ac7c9b3ad2e52abfe6b79a80045e4218eeb87175/ Signed-off-by: Vicente Olivert Riera [Thomas: - remove uClibc-specific SSP check, since there is now a generic check being done. - send potential compilation errors caused by the SSP check to oblivion, in order to avoid causing confusion for the user. - add autobuilder reference.] Signed-off-by: Thomas Petazzoni

toolchain: like glibc, musl always provides SSP support

2015-10-18T13:35:42+00:00

Make sure BR2_TOOLCHAIN_USES_MUSL selects BR2_TOOLCHAIN_HAS_SSP since musl always provides SSP support (like glibc). Signed-off-by: Thomas Petazzoni Acked-by: "Yann E. MORIN" Signed-off-by: Thomas Petazzoni

toolchain: make IPv6 mandatory for external toolchains

2015-04-22T20:59:31+00:00

Remove BR2_INET_IPV6 select for predefined external toolchains. Remove the (non)IPv6 option prompt since it's now mandatory. And force the toolchain check now that internal uclibc is always built with IPv6 support and external non-IPv6 toolchains are disallowed.

toolchain: remove LARGEFILE selects

2015-04-01T20:42:47+00:00

There's no need for toolchains or the user to declare largefile support since it's now mandatory. Signed-off-by: Gustavo Zacarias Signed-off-by: Thomas Petazzoni

toolchain: disable internal for blackfin

2015-03-17T16:53:13+00:00

The internal toolchain was a "best effort" approach - we strived to make it build properly and all but it's mostly untested. Since it's got issues disable it until it's properly fixed and tested and leave the official ADI toolchain instead. Signed-off-by: Gustavo Zacarias Signed-off-by: Thomas Petazzoni

toolchain: Enable the internal toolchain for nios2

2015-02-19T21:04:26+00:00

For now we can only support glibc. Signed-off-by: Ezequiel Garcia Signed-off-by: Thomas Petazzoni

toolchain: enable internal for aarch64

2014-04-24T13:21:13+00:00

Enable the internal toolchain backend for aarch64. Tested with arm_foundationv8_defconfig and ARMs foundation v8 emulator. Both glibc & eglibc work. Signed-off-by: Gustavo Zacarias Signed-off-by: Peter Korsgaard

toolchain: add a hidden config option to enable the toolchain package

2014-04-16T17:37:08+00:00

The usual way to enable a package using the package infrastructure is to use a config option so instead to add the toolchain package to the TARGETS variable in the Makefile add a config option like all the other toolchain packages. [Thomas: remove comment that no longer made sense in the main Makefile, and add a comment above the new hidden Config.in option to explain what it is useful for.] Signed-off-by: Fabio Porcedda Cc: Arnout Vandecappelle Cc: Yann E.

toolchain: introduce a toolchain knob for NPTL

2014-02-22T22:39:01+00:00

As our architecture support expands to a number of architectures that do not implement NPTL threading, and the number of packages that depend on NPTL specific features, it has become necessary to be able to know whether the toolchain has NPTL support or not. This commit adds a new BR2_TOOLCHAIN_HAS_THREADS_NPTL hidden Config.in option that allows packages to know whether NPTL is available or not. This hidden option is: * Automatically enabled when glibc/eglibc or musl toolchains are used, either internal or external. * Automatically enabled when an internal uClibc toolchain with NPTL support is configured. It is left disabled otherwise for internal uClibc toolchains. * Configured according to a visible Config.in option for custom external uClibc toolchains. [Peter: factor _EXTERNAL_HAS_THREADS in single if as suggested by Arnout] Signed-off-by: Thomas Petazzoni Signed-off-by: Peter Korsgaard

toolchain: enable microblaze toolchain

2013-12-06T21:46:44+00:00

This commit allows to build an internal toolchain for the Microblaze architecture, with either glibc or eglibc. Note that we add an explicit list of architectures that are supported by uClibc, and Microblaze is not part of them, because it currently doesn't build for this architecture. [Thomas: add better commit log, add architecture dependencies on uClibc, to avoid selecting uClibc on Microblaze] Signed-off-by: Spenser Gilliland Signed-off-by: Thomas Petazzoni Signed-off-by: Peter Korsgaard
