gdb: fix kconfig dependency handling with !BR_TOOLCHAIN_BUILDROOT

2011-11-24T13:26:52+00:00

Newer versions of GDB need pthread debugging support if threads are enabled, which is always the case for glibc but is a configure option for uClibc. We have solved this for internal toolchains by selecting the BR2_PTHREAD_DEBUG option from the GDB selection if needed, but as this option isn't available when ctng/external toolchains are used, mconf prints ugly warnings and the build may fail if an external uClibc toolchain without pthread debugging support is used. Fix it by introducing 2 more hidden config options: - BR2_TOOLCHAIN_HAS_THREADS_DEBUG - BR2_TOOLCHAIN_HAS_THREADS_DEBUG_IF_NEEDED The first tells us if the toolchain HAS pthreads debugging support, and is checked by check_uclibc_feature in helper.mk for external uClibc based toolchains. The second tells us if the toolchain is ABLE TO provide pthreads debugging support if threads are enabled, either because it's an internal toolchain where we can force enable it or an external glibc/eglibc toolchain or uClibc with the option enabled. Crosstool-ng forcibly enables this support, so those will always work. The preconfigured uClibc-based toolchains we have also all enable it. Finally, show a comment if this isn't the case so the (external toolchain) user knows why. This is placed outside the choice option, as menuconfig has a bug where it doesn't show choice selections which only contain comments. Signed-off-by: Peter Korsgaard

toolchain: Add the possibility to have a mcpu option with wrapper

toolchain: Correct test for external tools symlink creation

2011-11-02T10:46:07+00:00

When the external tools chain is installed in a path that match one of the first case test, all symlink are created to the external wrapper. The proposed solution is to test only the base name not the full path. Signed-off-by: Stany MARCEL Reviewed-by: "Yann E. MORIN" Signed-off-by: Peter Korsgaard

external-toolchain: Slightly optimize toolchain extraction

2011-10-10T07:46:36+00:00

Some CodeSourcery toolchains contain a huge number of locales that are not useful, even though they account for 70-80% of the total toolchain size. By skipping the extraction of those useless locales, we make the toolchain extraction process slightly faster, and also make the output directory size a lot smaller (host/opt/ is 213 MB instead of 1.5 GB with a 2010.09 ARM CodeSourcery toolchain).

ext-toolchain: Take into account Mentor Graphics acquisition of CodeSoucery

2011-10-09T19:36:22+00:00

Now that CodeSourcery has been bought by Mentor Graphics, the toolchains are named "Sourcery CodeBench". We rename the config short description and adjust the help text, but we keep the option name in order not to break existing configurations. Signed-off-by: Thomas Petazzoni Acked-by: "Yann E.
