Remove trailing whitespace from generated nano.spec file. Signed-off-by: Kumar Gala <kumar.gala@linaro.org>
2021-02-19newlib-nano: Create symlinks for nano-suffixed libsAlexey Brodkin1-0/+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..

2021-01-14newlib-nano: Build libstdc++ against newlib-nano if requestedKeith Packard1-0/+45
This uses the gcc support for building libstdc++ using alternate lib header files. Signed-off-by: Keith Packard <keithp@keithp.com>
2021-01-14Create nano.spec file that sits atop the existing nano buildKeith Packard1-0/+16

2021-01-14Add newlib-nano as companion libKeith Packard1-0/+128
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>
