* | Add newlib-nano as companion libKeith Packard2021-01-141-0/+224
|/ | | | | | | This allows building newlib-nano in addition to newlib and picolibc, allowing users to select between C libraries within the same toolchain. Signed-off-by: Keith Packard <keithp@keithp.com>
* picolibc: Build libstdc++ against picolibc if requestedKeith Packard2021-01-111-0/+10
| | | | | | | This uses the gcc support for building libstdc++ using alternate lib header files. Signed-off-by: Keith Packard <keithp@keithp.com>
* gcc: Add support for building libstdc++ with alternate libcKeith Packard2021-01-111-1/+1
| | | | | | | This adds another mode to do_gcc_core_backend that builds libstdc++ against an alternate libc implementation. Signed-off-by: Keith Packard <keithp@keithp.com>
* picolibc: Clean up configuration a bitKeith Packard2021-01-111-1/+2
| | | | | | | | | | | Use LIBC_PICOLIBC_CXA_ATEXIT to keep this name in the same 'namespace' as the other picolibc config names. Enable retargetable locking by default. This allows the few locks in picolibc to be implemented by the execution environment, rather than disabling the locking code. Signed-off-by: Keith Packard <keithp@keithp.com>
* picolibc: Convert to companion libraryKeith Packard2021-01-081-8/+5
| | | | | | | This allows configurations to include picolibc without excluding another C library. Signed-off-by: Keith Packard <keithp@keithp.com>

* | Clarify tree layout of local patches directoryBagas Sanjaya2020-10-131-2/+4
| | | | | | | | | | | | | | | | | | | | | | Currently the help for LOCAL_PATCH_DIR did not specify the tree layout of custom patches directory. This commit adds such explanation. For example, the bundled patches for GCC are placed under packages/gcc/<gcc-version>, thus custom (local) GCC patches should be placed under $LOCAL_PATCH_DIR/gcc/<gcc-version>.
