2020-12-23libgmp: Fix cross-canadian build for macOSAlexey Brodkin1-0/+9
Currently when building cross-canadian toolchain for macOS the folowing error happens when GCC is configured: |ld: illegal text-relocation to '___gmp_binvert_limb_table' in |... /.build/... /buildtools/complibs-host/lib/libgmp.a(mp_minv_tab.o) from '___gmpn_divexact_1' in |... /.build/... /buildtools/complibs-host/lib/libgmp.a(dive_1.o) |collect2: error: ld returned 1 exit status Apparently this might be solved with GMP configured with "--with-pic", even though we're talking about static library here.

2020-12-23gcc: Make it aware of Newlib nano IO featureAlexey Brodkin1-0/+5
Even though GCC as a compiler has nothing to do with a C library being used it still makes sense to know about Newlib's compact implementation of IO functions: * For targets like MSP430 which require to have such a tuned Newlib if "-mtiny-printf" is passed to the GCC's command-line [1] * For correct compilation of the following GCC's own DejaGnu tests [2]: - gcc/testsuite/gcc.c-torture/execute/920501-8.c - gcc/testsuite/gcc.c-torture/execute/930513-1.c - gcc/testsuite/gcc.dg/torture/builtin-sprintf.c - gcc/testsuite/gcc.c-torture/execute/ieee/920810-1.x [1] https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=02afb6a9321fbfb435452636cedc2cd43f0c4fd2 [2] https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=571bbd0d48d5872eacbd0b681fce6e1ae754520b So we add that missing cross-dependency now.

2020-10-14binutils: Disable glob for better portabilityAlexey Brodkin1-0/+4
Since glibc 2.27 glob interface was changed [1] and so "glob" & "glob64" symbols require glibc 2.27+. For us that means if we build Binutils on a machine with glibc 2.27+ produced binaries won't be any longer usable on machines with older glibc. As an example [2]: build on Ubuntu 18.04 (with glibc 2.27) and try to run on CentOS 7.x (with glibc 2.17), you'll see this: ---------------------->8------------------- ldd ld ld: /lib64/libc.so.6: version `GLIBC_2.27' not found (required by ld) ---------------------->8------------------- Now given glob is not really used by Binutils itself (only needed by GDB) and we build Binutils & GDB separately let's make at least Binutils more portable. In theory we may even try to do the same hack for GDB forcing it to use imported glob implementation. But since GDB is now built strictly by C++ compiler we'll get waaay to many incompatibilities due to multiple changes of C++ ABI in between GCC 7.5 of Ubuntu 18.04 and GCC 4.8.5 of CentOS 7.x, so there's no point to even try.

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.

2020-10-05glibc: set glibc build system default_cflags emptyHans-Christian Noren Egtvedt1-0/+2

2020-05-26Enable static libgcc when CT_GDB_NATIVE_STATIC_LIBSTDCXX is setStephanos Ioannidis1-0/+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++.

2019-06-14ARC: Support building of multi-lib Glibc toolchainAlexey Brodkin1-0/+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.
