toolchain: add variadic MI thunk support flag

2019-02-04T20:53:20+00:00

GCC uses thunk functions to adjust the 'this' pointer when calling C++ member functions in classes derived with multiple inheritance. Generation of thunk functions requires support from the compiler back end. In the absence of that support target-independent code in the C++ front end is used to generate thunk functions, but it does not support vararg functions. Support for this feature is currently missing in or1k and xtensa toolchains. Add hidden option BR2_TOOLCHAIN_SUPPORTS_VARIADIC_MI_THUNK that indicates presence of this feature in the toolchain. Add dependency to packages that require this feature to be built. Fixes: http://autobuild.buildroot.net/results/c9e660c764edbd7cf0ae54ab0f0f412464721446/ http://autobuild.buildroot.net/results/9a3bf4b411c418ea78d59e35d23ba865dd453890/ Signed-off-by: Max Filippov Signed-off-by: Thomas Petazzoni

Introduce the variable BR2_TOOLCHAIN_HAS_UCONTEXT

2019-02-04T10:00:01+00:00

It is set when the platform exposes the struct ucontext_t. This avoids duplication of logic inside each package requiring the use of that type. Signed-off-by: Patrick Havelange Signed-off-by: Peter Korsgaard

toolchain-external: update Arm AArch64 toolchain 8.2-2018.11

2019-01-04T11:45:17+00:00

>From [1]: * All GCC 8.2 features. For details on GCC 8 release series. * Linaro specific pre-processor macros to ensure that this is a continuation from the Linaro releases. * Spectre v1 mitigation backport from upstream FSF trunk include the revisions. This is an initial backport of those mitigations in the GNU toolchain and should be regarded as support for prototyping and early access only. Moreover, while the backports include support for the other architectures, they are included for completeness and all issues regarding these patches must be taken up upstream in the https://gcc.gnu.org/bugzilla by reproducing the same with upstream FSF trunk. Arm is interested in feedback regarding these workarounds for Spectre v1. A description of the mitigation has been published on LWN.net. See "Release Note": [1] https://developer.arm.com/open-source/gnu-toolchain/gnu-a/downloads# Tested with qemu_aarch64_virt_defconfig. Signed-off-by: Romain Naour Signed-off-by: Peter Korsgaard
