* mpfr: Add support of building MPFR for targetYuriy Kolerov2023-05-191-3/+53
| | | | | | | | It's necessary for building native GDB 13+. It depends on MPFR but it hasn't presented in scripts yet for building for target. Signed-off-by: Yuriy Kolerov <ykolerov@synopsys.com>
* newlib: Add missing linker options for nano.specsYuriy Kolerov2023-05-101-1/+1
| | | | | | | | Old options %(newlib_nano_link) for the linker must be passed otherwise linking may fail. E.g., in case of multilib configurations a correct emulation mode may be not passed. Signed-off-by: Yuriy Kolerov <ykolerov@synopsys.com>
* picolibc: Allow default memory layout values to be configuredKeith Packard2023-04-191-0/+4
| | | | | | | | These values are used when constructing the default linker scripts used with picolibc. Setting reasonable defaults allows simple test applications to be compiled without additional configuration. Signed-off-by: Keith Packard <keithp@keithp.com>
* picolibc: Don't disable libstdc++ wchar_t for 1.8.1 or newerKeith Packard2023-04-191-1/+3
| | | | | | | Picolibc 1.8.1 has wchar_t stdio support, so libstdc++ can include it. Signed-off-by: Keith Packard <keithp@keithp.com>
* picolibc: Add configuration to select picolibc as the system libcJoakim Nohlgård2023-03-081-69/+83

* Enable support for building libgccjitMarc Poulhiès2022-12-186-5/+39
| | | | | | | | | | | | | | | | | | | | | libgccjit is still under development and, despite its name, may also be used for ahead-of-time compilation. Documentation can be found on the gcc website: https://gcc.gnu.org/onlinedocs/jit/internals/index.html https://gcc.gnu.org/wiki/JIT With this change it's possible to enable the building of the libgccjit. It's enabled as a language (with --enable-languages=jit) even if not a language frontend at all. The main changes are related to the requirement of having everything host side built as Position Independent Code (PIC) with --enable-host-shared. GCC has the needed logic for building its dependencies (mpc, gmp, mpfr, ...) correctly when built "in-tree", which is not the case with crosstool-ng (see https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=05048fc29f0) Signed-off-by: Marc Poulhiès <dkm@kataplop.net>
* gmp: Set CC_FOR_BUILD and CPP_FOR_BUILDChris Packham2022-05-311-2/+5
| | | | | | | | | When GMP is being "cross" compiled for the same architecture (i.e. build == host) it does not pick the right compiler. Set CC_FOR_BUILD and CPP_FOR_BUILD to override the default compiler. Fixes #1328 Signed-off-by: Chris Packham <judge.packham@gmail.com>
* newlib-nano: Fix include path for CT_NEWLIB_NANO_INSTALL_IN_TARGETStephanos Ioannidis2022-05-121-1/+1
| | | | | | | | | | | | | | | | | | When `CT_NEWLIB_NANO_INSTALL_IN_TARGET=y`, the `nano.specs` file emitted by the newlib-nano build script contains an invalid include path, resulting in the full `newlib.h` being included instead of the nano `newlib.h` by the application. `=/include/newlib-nano` is not a valid path (`=` does not mean anything and that string is taken as an include path as-is) and GCC ignores this include path, resulting in application including the `newlib.h` from `include/` which contains the newlib build configurations for the full newlib. This commit modifies the newlib-nano build script to emit a proper newlib-nano include path relative to the `GCC_EXEC_PREFIX`. Signed-off-by: Stephanos Ioannidis <root@stephanos.io>

This concludes the glorious history of the original uClibc (non-NG) with lots of kludges removed. There was a choice here, whether to call the resulting libc "uClibc" or "uClibc-ng". I opted in favor of giving uClibc-ng the recognition it deserves, although it had some ripple effect in the ct-ng code. Signed-off-by: Alexey Neyman <stilor@att.net>

* gnuprumcu: Bump to v0.6.0Dimitar Dimitrov2021-08-221-5/+4
| | | | | | | | | | | | Changes since v0.5.0: * Add spec files for am64x SoCs. * Require Binutils at least version 2.37. * Require pru-gcc to be installed. * Remove linker scripts. Instead set memory sizes from specs. * Activate --gc-sections linker option by default. * The "--host=pru" configure option must be used instead of "--target=pru.

* newlib-nano: Fix nano.spec based on CT_NEWLIB_NANO_INSTALL_IN_TARGETKumar Gala2021-07-301-1/+28
| | | | | | | | | The spec file was missing replacing various libs like libc, libm, etc with their nano equiv when CT_NEWLIB_NANO_INSTALL_IN_TARGET=y.

* newlib: Add libstdc++ nano-specific CXXFLAGSStephanos Ioannidis2021-06-071-0/+3
| | | | | | | | | | | This commit adds a new config that can be used to specify the target CXXFLAGS specific to the libstdc++ newlib-nano variant. By default, this config is set to specify the `-fno-exceptions` option, which disables C++ exception handling support and greatly reduces the compiled binary size.

| * newlib-nano: Use run-time calculated paths in top-level nano.specsAlexey Brodkin2021-04-161-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In currently generated top-level "nano.specs" we resolve paths during toolchain building and then use those pre-defined full paths once the toolchain got built. That's OK until the toolchain is used right were it was built, otherwise paths used in the top-level "nano.specs" become irrelevant and linker fails to find "nano" libs reverting to non-"nano" libs in the default location.

* | newlib-nano: Add option to copy libs into targetKumar Gala2021-04-151-0/+25
| | | | | | | | | | | | | | | | | | | | | | Add an option that will install a copy of newlib-nano lib*.a file in the target dir but renamed with a nano.a suffix (eg: libc_nano.a) as some default nano.spec files from newlib expect this setup. Additionally the newlib-nano version of newlib.h will get copied to include/newlib-nano/newlib.h. Signed-off-by: Kumar Gala <kumar.gala@linaro.org>

* newlib-nano: Create symlinks for nano-suffixed libsAlexey Brodkin2021-02-191-0/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | If existing board's .specs are used for linking of a user's application, then instead of normally used libs like libc.a & libstdc++.a might be requested their "nano"-suffixed siblings: libc_nano.a, libstdc++_nano etc. That way: ----------------------------->8--------------------------- %rename link_gcc_c_sequence myboard_link_gcc_c_sequence *myboard_libc: %{!specs=nano.specs:-lc} %{specs=nano.specs:-lc_nano} *link_gcc_c_sequence: %(myboard_link_gcc_c_sequence) --start-group %G %(myboard_libc) --end-group ----------------------------->8--------------------------- Our companion newlib-nano libs are all built optimized for size, so we'd like to use them for linking. But given linker will see "-lc_nano -lstdc++_nano" on its command line non-suffixed libs will be ignored. To solve it we create those "_nano"-suffixed libraries as simple symlinks to existing libs..
