package/binutils: add optional support for zlib

2016-02-21T20:30:17+00:00

When zlib was compiled before, binutils will use it as optional dependency: $ output/host/usr/bin/x86_64-linux-readelf -a output/target/usr/lib/libbfd-2.24.so | grep NEEDED 0x0000000000000001 (NEEDED) Shared library: [libz.so.1] 0x0000000000000001 (NEEDED) Shared library: [libc.so.1] Apparantly the build system offers no support to control the dependency, --without-system-zlib with zlib installed still provides libbfd-2.24.so linked to libz.so.1.

toolchain: bump ARC toolchain components to arc-2015.12

2016-02-05T20:48:51+00:00

This change introduces newer ARC toolchain in Buildroot. That new arc-2015.12 release doesn't bring any significant changes but mostly is focused on fixes and minor improvements here and there. Most noticeable changes are: * GCC: Source update to v4.8.5 * GDB: Updated to upstream 7.10 release. You may find more info on fixes and improvements in that release at: https://github.com/foss-for-synopsys-dwc-arc-processors/toolchain/releases/tag/arc-2015.12 Signed-off-by: Lada Trimasova Cc: Alexey Brodkin Cc: Thomas Petazzoni Cc: Peter Korsgaard Signed-off-by: Thomas Petazzoni

binutils: ensure TARGET_CONFIGURE_ARGS is taken into consideration for subdirs

2016-02-01T22:46:45+00:00

Binutils runs the configure scripts of subdirs at make time, so we need a custom build command to ensure TARGET_CONFIGURE_ARGS are taken into consideration for those (E.G. for musl gettext handling). Reported-by: Bernd Kuhls Signed-off-by: Peter Korsgaard

toolchain: bump ARC toolchain components to arc-2015.12-rc1

2016-01-19T21:01:37+00:00

This change introduces newer ARC toolchain in Buildroot. Note this is the first release candidate and we'll probably see another RC before cutting the final release. That new arc-2015.12 release doesn't bring any significant changes but mostly is focused on fixes and minor improvements here and there. Most noticeable changes are: * GCC updated to v4.8.5 * GDB updated to 7.10 You may find more info on fixes and improvements in that release at: https://github.com/foss-for-synopsys-dwc-arc-processors/toolchain/releases/tag/arc-2015.12-rc1 Signed-off-by: Alexey Brodkin Cc: Thomas Petazzoni Cc: Peter Korsgaard Cc: arc-buildroot@synopsys.com Signed-off-by: Thomas Petazzoni

binutils: remove unnecessary host-texinfo dependency

2015-09-20T12:57:02+00:00

host-texinfo dependency was only necessary when building the git version of binutils, however, this upstream commit allows binutils to build without makeinfo (a binary provided by host-texinfo)... https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=commit;h=bba33ab1e0f7d2ebd8f8435f92ed12e2a3c558a4 ...so we can safely remove the host-texinfo dependency.

ARC: update tools to arc-2015.06 release

2015-07-18T09:13:31+00:00

I'm happy to update GNU tools for ARC cores to the most recent arc-2015.06 release. This release brings following major improvements: * GCC: source update to v4.8.4 * GCC: C ABI compatibility between MetaWare and GNU toolchains * uClibc: support for thread local storage and Native Pthread Library (NPTL) * GDB: updated to version 7.9.1 Also a lot of fixes and improvements has been done, please refer to https://github.com/foss-for-synopsys-dwc-arc-processors/toolchain/releases/tag/arc-2015.06 for more details.

binutils: use binutils 2.24 by default on the target

2015-07-13T15:32:36+00:00

When binutils is not built for the host, binutils.mk decides of the version to be used when building binutils for the target. We're still using the old 2.22 binutils version, but it's time to bump up to 2.24, which we already use as the default version for the host.

binutils: update to the latest ARC version by default

2015-06-30T10:36:34+00:00

Following commit 36555b4c8dce27822ecbbed58798f887ad452b18 ("ARC: switch to RC1 of upcoming arc-2015.06 tools"), the binutils package only contains the hash information for the 2015.06-rc1 ARC version of binutils (which is in fact no hash). However, when an external toolchain is used, and binutils is built for the target, it's still the old 2014.11 binutils version that gets used in binutils.mk, causing a build failure because there is no hash available for this version. This commit fixes that by using 2015.06-rc1 as the default binutils version on ARC, which is used when no host-binutils has been built.

binutils: fix target binutils on ARC

2015-03-15T15:58:17+00:00

When an external toolchain is used on ARC, BR2_BINUTILS_VERSION is undefined, so we use binutils 2.22, which doesn't support ARC and anyway isn't available from the ARC download location. So, let's defined a default ARC binutils version in binutils.mk. Fixes: http://autobuild.buildroot.org/results/52a/52abadacd7aab2d5c11d094937f28198bf220662/ Signed-off-by: Thomas Petazzoni

toolchain: add link-time-optimization support

2015-03-07T14:01:53+00:00

Add a new option BR2_GCC_ENABLE_LTO that builds gcc and binutils with LTO support. Individual packages still have to enable LTO explicitly by passing '-flto' to GCC, which passes it on to the linker. This option does not add that flag globally. Some packages detect if the compiler supports LTO and enable the flag if it does. To support LTO, ar and ranlib must be called with an argument which triggers the usage of the LTO plugin. Since GCC doesn't call these tools itself, it instead provides wrappers for ar and ranlib that pass the LTO arguments. This way existing Makefiles don't need to be changed for LTO support. However, these wrappers are called -gcc-ar which matches the pattern to link to the buildroot wrapper in the external toolchain logic. So the external toolchain logic is updated to provide the correct symlink. [Thomas: - Add a separate BR2_BINUTILS_ENABLE_LTO option to enable LTO support in binutils. This is a blind option, selected by BR2_GCC_ENABLE_LTO. It just avoids having binutils.mk poke directly into gcc Config.in options. - Remove the check on the AVR32 special gcc version, which we don't support anymore. - Adapt the help text of the LTO Config.in option to no longer mention "Since version 4.5", since we only support gcc >= 4.5 in Buildroot anyway. - Fix typo in toolchain-external.mk comment.] Signed-off-by: Peter Kümmel Signed-off-by: Thomas Petazzoni
