2021-06-07gcc: Allow setting custom target CXXFLAGSStephanos Ioannidis1-3/+26
This commit adds two additional arguments (`cxxflags_for_target` and `extra_cxxflags_for_target`) for the gcc backend build function that can be used to specify custom target CXXFLAGS. By default, the target CXXFLAGS is set to the target CFLAGS. When `cxxflags_for_target` is specified however, it overrides that behaviour and allows setting different target CXXFLAGS from the target CFLAGS. The `extra_cxxflags_for_target` argument can be used to specify the extra target CXXFLAGS to be appended to the target CXXFLAGS. This is useful when it is necessary to append CXX-specific flags to the existing CFLAGS to be used as the target CXXFLAGS. A useful application of this is building full and nano versions of libstdc++ with different target CXXFLAGS as necessitated by `nano.specs`. Signed-off-by: Stephanos Ioannidis <root@stephanos.io>
2021-06-07gcc: Assume '-O2' by default for building gcc target librariesStephanos Ioannidis1-3/+11
The gcc target libraries (e.g. libstdc++) are currently built without any optimisation flag when `CT_CC_GCC_ENABLE_TARGET_OPTSPACE` is not enabled and default to `-O0` unless user explicitly specifies an optimisation flag. This commit updates the gcc build script to assume `-O2` for building target libraries unless user provides a different optimisation flag. Note also that this is the default behaviour for gcc when C[XX]FLAGS_FOR_TARGET is not overridden. Signed-off-by: Stephanos Ioannidis <root@stephanos.io>

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.

2017-09-03Super-H multilib toolchain fixesAlexey Neyman1-1/+1
1. On SuperH, configuring GCC with explicit variant of the CPU (like "sh4") limits the default set of multilibs to just that CPU and requires --with-multilib-list to change. Allow for "unspecified" variant, so that we can defer to GCC to determine the list. 2. Support toolchains with both endiannesses at the same time. 3. Add a SuperH/newlib sample 4. Add more flags processing for uClibc Signed-off-by: Alexey Neyman <stilor@att.net>

2015-04-07Only create ${CT_TARGET}-cc${ext} symlink if ${CT_TARGET}-gcc existsJohannes Pfau1-2/+6
Without this canadion cross builds create invalid symlinks: When the code in do_cc_core_backend is called there is no ${CT_TARGET}-gcc in the install directory. Therefore ext is empty and we create a link to ${CT_TARGET}-gcc. The final compiler step then installs ${CT_TARGET}-gcc.exe and creates a working ${CT_TARGET}-cc.exe symlink but we still keep the invalid link as well.

2014-12-09gcc and gdb: fix fetching linaro builds (part two)Bryan Hundven1-1/+1
It's not my day. linaro_version is a filter. If it is not a linaro toolchain, it will just be CT_{CC,GDB}_VERSION. If it is a linaro toolchain, CT_{CC,GDB}_VERSION will be prefixed with 'linaro-' and will not match linaro_version, as linaro_version will just have the part after 'linaro-'.

2014-05-10cc/gcc: allow CC_EXTRA_CONFIG_ARRAY on baremetalCody Schafer1-1/+5
The final bare-metal compiler is built using the core backend. Currently the core uses the CC_CORE_EXTRA_CONFIG_ARRAY variable. While this works as supposed to, this can leave the user puzzled in the menuconfig, since all he can see is the core options, not the final options. Only show the core options if any of the core passes are needed, and use the final options in the core-backend if we're issuing the bare-metal compiler.

2014-01-04cc/gcc: diable libsanitizer without NPTLYann E. MORIN"1-0/+3
gcc-4.8 comes with a new library to sanitise memory access: - heap-, stack-, and global-buffer overflow, use-after-free - data-races between threads This library requires some _np parts of the API, which are not implemented in the (old) LinuxThreads, which is still available in uClibc. Since NPTL requires a i486 or above, i386 are stuck with using LT, which precludes building the libsanitizer. Disable libsanitizer, a bit like libatomic is. Signed-off-by: "Yann E.
