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.

binutils: fix .init/.fini literals moving in xtensa gas

2016-02-18T14:07:43+00:00

Despite the documentation and the comment in xtensa_move_literals, in the presence of --text-section-literals and --auto-litpools literals are moved from the separate literal sections into .init and .fini, because the check in the xtensa_move_literals is incorrect. This fixes build errors seen with projects that have .init/.fini and use text-section-literals.

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.

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: fix building perf on ARC

2015-10-17T14:16:53+00:00

It turned out one of the previous fixes (required to build Linux kernel) ------------------>8------------------- ARC Binutils: https://github.com/foss-for-synopsys-dwc-arc-processors/binutils-gdb/commit/a65b844aed9153789356e098984452df2f5d9058 Buildroot: http://git.buildroot.net/buildroot/commit/?id=2d4e2e238a0ea9395152ae71d882d79b1f35094c ------------------>8------------------- broke building of some other software packages. In particular perf built for ARCv2 had corrupted .plt entries that lead to immediate crash on perf execution. That's an example of normal .plt entries: ------------------>8------------------- < 1-st PLT entry >: 12c24: 30 27 8c 7f 0d 00 74 95 ld r12,[pcl,0x000d9574] 12c2c: 21 20 00 03 j.d [r12] 12c30: 0a 24 c0 1f mov r12,pcl < 2-nd PLT entry >: 12c34: 30 27 8c 7f 0d 00 68 95 ld r12,[pcl,0x000d9568] 12c3c: 21 20 00 03 j.d [r12] 12c40: 0a 24 c0 1f mov r12,pcl ------------------>8------------------- Note right after jump in its delay-slot r12 gets set with current value of program counter. This is required for the first symbol resolution, see implementation of _dl_linux_resolve here: http://git.uclibc.org/uClibc/tree/ldso/ldso/arc/resolve.S#n46 And that's what we got in .plt after mentioned fixes: ------------------>8------------------- < 1-st PLT entry>: 13384: 30 27 8c 7f 0f 00 84 75 ld r12,[pcl,0x000f7584] 1338c: 21 20 00 03 j.d [r12] < 2-nd PLT entry>: 13390: 30 27 8c 7f 0f 00 78 75 ld r12,[pcl,0x000f7578] 13398: 21 20 00 03 j.d [r12] ------------------>8------------------- Note r12 setup is missing. That happened because linker thought the size of PLT entry is 12 bytes (which is exactly the size of PLT entry for ARCv1, read ARC750/770) while for ARCv2 PLT entry is 16-bytes long. And erroneously trailing 4 bytes were truncated. Current commit fixes this misbehavior and PLT gets generated properly again. Now we have a fix for that issue, see https://github.com/foss-for-synopsys-dwc-arc-processors/binutils-gdb/commit/5df50c61083165455aae5504c5c3566fa5ccebb1 This fix is in arc-2.23-dev branch and will be a part of the next release of ARC tools, so then this patch must be removed from buildroot.

binutils: backport auto-litpools xtensa gas option

2015-10-04T16:27:27+00:00

Auto-litpools is the automated version of text-section-literals: literal pool candidate frags are planted every N frags and during relaxation they are turned into actual literal pools where literals are moved to become reachable for their first reference by L32R instruction.
