gdb: arc: remove C++ dependency and disable build with C++

2016-11-15T22:08:15+00:00

gdb arc-2016.09-rc1 is based on upstream 7.12 gdb version where we can still disable C++ build. For more information take a look at: https://sourceware.org/gdb/wiki/cxx-conversion We wanted to build gdb with C++ as it is used as default in 7.12 and is even a mandatory requirement since 2016/09. But unfortunately we missed one runtime failure that C++ build causes and so now we have to disable C++ build. When gdb arc-2016.09-rc1 is built as a C++ application it segfaults at runtime for ARC. We are going to fix the issue in 2017.03 ARC toolchain release. and before this we remove C++ dependency are adding temporary workaround to prevent runtime segfaults. The workaround is to disable building gdb as C++ application via passing --disable-build-with-cxx config option when building gdb for ARC.

package/gdb: disable simulator support for microblaze

2016-11-14T22:48:12+00:00

The gdb simulator seems missing with the Xilinx fork of gdb. Disable it for microblaze since only the Xilinx version of gdb is currently available.

toolchain: Bump ARC tools to arc-2016.09-rc1

2016-11-14T20:40:58+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-rc1. This update contains a lot of important fixes, e.g. it fixes: http://autobuild.buildroot.net/results/4c7/4c77f33c842b37bf28cb931edf1b290e1bf4d93c// http://autobuild.buildroot.net/results/902/902729a0b98675ad803939e3ecdcf230065a6012// and other failures. Other important change is that we also update gdb. Now we are using gdb 7.12. This version of gdb requires C++ toolchain support so we add corresponding dependency to gdb Config.in file. Signed-off-by: Vlad Zakharov [Thomas: - fix dependency on C++ of gdb, it must use BR2_INSTALL_LIBSTDCPP - add comment about the C++ dependency of gdb on ARC.] Signed-off-by: Thomas Petazzoni

toolchain: configs: improve toolchain config readability

2016-10-25T21:31:47+00:00

Add (or move) comment lines in toolchain-related Config.in files to improve readability of the toolchain config section. Source linux-headers/Config.in.host after toolchain-buildroot items. For toolchain-buildroot case, the config file now looks like this: * * Toolchain * * * Toolchain Buildroot Options * * * Kernel Header Options * * * uClibc Options * * * Binutils Options * * * GCC Options * * * Host GDB Options * * * Toolchain Generic Options * Signed-off-by: Petri Gynther Signed-off-by: Thomas Petazzoni

gdb: unbreak host/target install step

2016-10-14T17:32:43+00:00

Commit 12306a81f8edc (gdb: get rid of host-texinfo dependency) tried to append MAKEINFO=true to the host/target make install arguments, but as the default values for these are only added when (host-)autotools-package is evaluated (and only if empty), this effectively drops the default values and we ended up without the 'install' target and nothing got installed. To fix this, specify the full install arguments. Signed-off-by: Peter Korsgaard

gdb: get rid of host-texinfo dependency

2016-10-09T11:55:08+00:00

The host-texinfo dependency in gdb/host-gdb was added because gdb insisted in building info documentation in recent versions, and we want to avoid 'makeinfo' to be present on the build system. However, there is another solution that does not require actually building host-texinfo: instruct the makefiles to use a dummy makeinfo command ('true').

gdb: fix simulator build failures

2016-08-04T22:16:22+00:00

Following reports from me of build failures of the GDB simulator for the Blackfin architecture, Waldemar cooked a patch (0005-fix-sim-compile.patch) that removes the typedef of SIM_CPU, because there was a redefinition of this typedef for Blackfin. This was not causing an issue with recent compilers as redefining the same typedef is valid with recent compilers, but was causing build failures with gcc 4.4.x. However, by removing the common definition of SIM_CPU, this patch broke the build of the GDB simulator on other architectures, which did not had an architecture-specific redefinition of SIM_CPU (unlike Blackfin). The crux of the problem is in a commit from Mike Frysinger, that tries to refactor the SIM_CPU definition into a common one. Except that it leaves a redefinition of it for Blackfin. Removing this second definition however doesn't easily work, due to include ordering issues. The easiest solution is to simply revert the patch from Mike Frysinger. This allows to fix the build for all architectures and all compiler versions.

package/gdb: fix gnulib issue with musl and uClibc toolchains

2016-07-24T19:52:29+00:00

Starting with gdb 7.11, the bundled gnulib want to use rpl_gettimeofday (gettimeofday replacement) due bad guessing when cross-compiling with musl and uClibc toolchains. Instead of patching gnulib configure script to fix the test, use gl_cv_func_gettimeofday_clobber=no to not use rpl_gettimeofday. Thanks to Thomas Petazzoni to suggest this patch.
