toolchain: remove no longer relevant comment

2017-03-13T22:58:43+00:00

The somewhat complicated sed expression has been removed in commit 06cd604ec6d34f25b436ab729543418042a87e1c ("toolchain/external: use -dumpversion to check gcc version"), so let's remove the comment that was explaining this sed expression.

toolchain/external: use -dumpversion to check gcc version

2017-03-13T22:58:30+00:00

Currently, `--version` option is used and later matched with a regex to get the actual gcc version. There's a dedicated gcc option to do exactly that: `-dumpversion`. Also `--version` may return a string customised by a vendor that provides the toolchain, which makes the current regex approach error prone. In fact, this situation has been seen with a real customised toolchain.

Revert "reproducible: fix DATE/TIME macros in toolchain-wrapper"

2017-02-20T22:26:05+00:00

This reverts commit 76838f63412a30a358210e457dda4b79f7730624. The commit referenced above explicitly states that the function was copied as-is from the gcc source code at the time. And indeed that is exactly how the function appeared in gcc in commit e3e8c48c4a494d9da741c1c8ea6c4c0b7c4ff934. However, our toolchain wrapper is "GPLv2 only", while the file this function was copied from is "GPLv3 or later". As such we can't include that function and still comply to both licenses. Furthermore, the code is far from optimum. Since this feature is not release-critical, revert it until we re-implement it. Signed-off-by: "Yann E.

toolchain/toolchain-common.in: fix definition of BR2_TOOLCHAIN_HAS_GCC_BUG_64735

2017-02-09T20:31:28+00:00

The rework done on commit accba02a47942b54c01b506512ddccf34d57c357 ("toolchain: add option for toolchains affected by GCC PR libstdc++/64735") by me was wrong. The BR2_TOOLCHAIN_HAS_GCC_BUG_64735 option should be enabled when the bug is present in the toolchain, not the opposite. Signed-off-by: Thomas Petazzoni

toolchain: add option for toolchains affected by GCC PR libstdc++/64735

reproducible: fix DATE/TIME macros in toolchain-wrapper

2017-02-07T20:45:01+00:00

The use of the __DATE__ and __TIME__ macros are one of the most common sources of non-reproducible binaries. In order to fix that, gcc 7 supports the SOURCE_DATE_EPOCH variable: https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=e3e8c48c4a494d9da741c1c8ea6c4c0b7c4ff934 This patch take advantage of toolchain-wrapper to provide support of SOURCE_DATE_EPOCH to older gcc versions. Function get_source_date_epoch() come directly from gcc git. This work was sponsored by `BA Robotic Systems'.

toolchain-external: Update Synopsys prebuilt toolchain for ARC cores

2017-02-04T22:57:43+00:00

Sync external prebuilt toolchain with the one we now build in Buildroot, i.e. arc-2016.09. Since that prebuilt toolchain finally has IPv6 enabled it works pretty fine for building packages in Buildroot. Still note: 1) There might be subtle differences between uClibc configuration compared to Buildroot's one. 2) A couple of patches we apply on top of Builroot-built toolchain are obviously missing in the prebuilt version - they will be available in the next release.

uclibc: enable mips{32,64}r6 support

2017-02-03T19:56:18+00:00

The config for ISA choice is removed for a long time as the buildsystem does not pass -march=mips* to the compiler anymore. For mips{32,64}r6 support NAN selection is required. Tested with qemu mips32/mips64 defconfigs. A small patch is required. Bug found while testing qemu defconfigs. Signed-off-by: Waldemar Brodkorb Signed-off-by: Peter Korsgaard
