toolchain: Bump ARC tools to arc-2016.09-eng010

2016-08-31T07:32:29+00:00

As described at: 4520524ba055706236db9f00dd79f1b2e2e87fde this commit continues a series of updates of ARC tools. This time we're updating tools to arc-2016.09-eng010. This engenering build contains different fixes done to TLS and PIE features. Appropriate custom patches are removed as they have been added to eng010. We still keep GDB as it is of arc-2016.03 release because there're some issues we'd like to resolve before releasing it to wider audience. So again note this is next engineering builds of arc-2016.09 series and it might have all kinds of breakages, please don't use it for production builds.

gcc: fix conditional move constraint on ARC

2016-08-26T13:37:17+00:00

The patch solves one of the ARC internal compiler issues.

bfin: fix issues with internal toolchain, re-enable C++ support

2016-08-20T09:47:46+00:00

The three patches allow to compile applications using TLS emulation from libgcc or C++ applications. The patches 892-libgcc-mkmap-symver-support-skip_underscore.patch and 893-libgcc-config-bfin-use-the-generic-linker-version-in.patch fixes how libgcc is generated, by making the necessary libgcc symbols declared "GLOBAL", and therefore visible outside of libgcc. This fixes a large number of undefined reference issues (for either C++ applications or applications using TLS emulation). This was reported as gcc PR74748. The patch 894-libgcc-fix-DWARF-compilation-with-FDPIC-targets.patch allows to build DWARF in FDPIC mode. This patch replaces the older 892-disable-dwarf-bfin.patch, as instead of disabling DWARF support, it fixes it. This was reported as gcc PR68468. In order to get C++ working without unresolved symbols, we also need to disable symbol versioning (--disable-symvers). This is a remaining issue in gcc which will be investigated at a later point. Since this commit fixes C++ support in Blackfin, it re-enables the selection of C++ support for this architecture.

toolchain: Bump ARC tools to arc-2016.09-eng008

2016-08-11T13:07:06+00:00

As described at: 4520524ba055706236db9f00dd79f1b2e2e87fde this commit continues a series of updates of ARC tools. This time we're updating tools to arc-2016.09-eng008. Main updates were made for gcc. It was switched to GCC 6 and to OSABI v4. Besides this patch fixes buildroot ARC failures connected to "crtbeginT.o" object file missing. This issue lead to two main errors: 1) "crtbeginT.o: No such file or directory", e. g. bootutils-1.0.0. No comments are required here I hope. 2) Errors like "compiler cannot create executables", e.g.: a) host-gcc-final-arc-2016.09-eng007 static build, b) aespipe-2.4c. That was caused because the test to determine if compiler is able to create executables was failing due to missing "crtbeginT.o" file. We still keep GDB as it is of arc-2016.03 release because there're some issues we'd like to resolve before releasing it to wider audience. So again note this is next engineering builds of arc-2016.09 series and it might have all kinds of breakages, please don't use it for production builds.

gcc: disable C++ support for Blackfin

2016-08-10T12:54:47+00:00

As discussed with Waldemar, the C++ support for Blackfin is currently broken, and we don't have a fix in sight for the 2016.08 release. Therefore, this commit disables C++ support entirely on the Blackfin architecture in the internal toolchain backend. This will avoid a significant number of Blackfin build failures, that occur when building C++ packages. Signed-off-by: Thomas Petazzoni

gcc: bump 4.9 series to 4.9.4

2016-08-04T20:45:48+00:00

Two patches are removed, as they have been upstreamed: - 130-fix_build_with_gcc-6.patch (svn commit 233721, Git commit 8c3fa311caa86f61b4e28d1563d1110b44340fb2) - 920-libgcc-remove-unistd-header.patch (svn commit 226092, Git commit e940d7953f06af11d09229a29ecbcc1ba25b378d) All other patches have simply been refreshed, with no manual edit needed. A build+runtime test has been done with an ARM, Cortex-A8, EABIhf, musl configuration, booted under Qemu. Signed-off-by: Thomas Petazzoni

toolchain: Bump ARC tools to arc-2016.09-eng007 and enable PIE

2016-08-01T20:59:31+00:00

As described at: 4520524ba055706236db9f00dd79f1b2e2e87fde this commit continues a series of updates of ARC tools. This time we're updating tools to arc-2016.09-eng007 tag plus a couple of fixes on top of it that will all make its way in the next engineering build. We hope this patch will cure most buildroot ARC failures as it contains important fixes: 1) PIE fix. We have added PIE support to ARC toolchain at last. So that should prevent breakage of many packages. As ARC now supports PIE we remove ARC from BR2_TOOLCHAIN_SUPPORTS_PIE exclusion in toolchain/Config.in file. 2) Assembler fix. This patch also have changes that fixes frequent assembler failures, e.g.: http://autobuild.buildroot.net/results/543/5430b902d900943a34c1888e7e410bd5df367bc2// We still keep GDB as it is of arc-2016.03 release because there're some issues we'd like to resolve before releasing it to wider audience. So again note this is next engineering builds of arc-2016.09 series and it might have all kinds of breakages, please don't use it for production builds.

toolchain: Bump ARC tools to arc-2016.09-eng006

2016-07-12T21:59:11+00:00

As described at: 4520524ba055706236db9f00dd79f1b2e2e87fde this commit continues a series of updates of ARC tools. This engineering build fixes the kernel dwarf stack unwinder feature for ARC targets. We still keep GDB as it is of arc-2016.03 release because there're some issues we'd like to resolve before releasing it to wider audience. So again note this is next engineering builds of arc-2016.09 series and it might have all kinds of breakages, please don't use it for production builds.
