| * | m4: fix build for mingw32 hostFlorent Valette2020-10-061-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While building a canadian toolchain for windows host (any target), the build failed for m4 host companion_tool with a recent mingw-w64 (at least 7.0.0). m4 needs stack smashing protection which is not part of mingw-w64 c library and an explicit trigger to link w/ libssp is needed.

* | | glibc: set glibc build system default_cflags emptyHans-Christian Noren Egtvedt2020-10-051-0/+2
|/ / | | | | | | | | | | | | | | | | | | By setting glibc build system default_cflags to be empty before building, we will enforce the build system to only use the crosstool-ng CFLAGS when building glibc. Properly solves the issue identified in #1396. Signed-off-by: Hans-Christian Noren Egtvedt <hegtvedt@cisco.com>

| | | | | | | | | | | | | | picolibc is another bare-metal C library, and so should be mapped to CT_TARGET_SYS just like newlib does. Signed-off-by: Keith Packard <keithp@keithp.com>

* | Enable static libgcc when CT_GDB_NATIVE_STATIC_LIBSTDCXX is setStephanos Ioannidis2020-05-261-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit updates the GDB build script to specify `-static-libgcc` when `CT_GDB_NATIVE_STATIC_LIBSTDCXX` is enabled. Both libgcc and libstdc++ are considered to be part of the "standard libraries," and should be specified by the same flag (the configuration symbol could potentially use a better name and/or further indirection). This also semantically aligns the `CT_GDB_NATIVE_STATIC_LIBSTDCXX` with the equivalent GCC configuration `CT_CC_GCC_STATIC_LIBSTDCXX`, which also enables static linking of both libgcc and libstdc++.

| * | ARC: Support building of multi-lib Glibc toolchainAlexey Brodkin2019-06-141-0/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From GCC's standpoint ARC's multilib items are defined by "mcpu" values which we have quite a few and for all of them might be built optimized cross-toolchain. From Glibc's standpoint multilib is just multi-ABI [1] and so very limited versions are supposed to co-exist (e.g. arc700 & archs). Here we force Glibc to install libraries in GCC's multilib folder to create a universal cross-toolchain that has libs optimized for multiple CPU types. But note we only need to mess with installation paths in case of real multilib, otherwise we keep default "lib/" paths so that GCC finds default (the one and only) libs where it expects them to be. Also here we add a sample which allows to build universal Glibc Linux toolchain for ARC.
