Picolibc version 1.8.6

  • Fix some FORTITY_SOURCE issues with tinystdio

  • Add __eh_* symbols to picolibc.ld for LLVM libunwind. Thanks Alex Richardson.

  • Merge in newlib annual release (4.4.0). Some minor updates to aarch64 assembly code formatting (thanks to Sebastian Huber) and a few other fixes.

  • Enable 32-bit SPARC for testing.

  • Fix a bunch of fmemopen bugs and add some tests. Thanks to Alex Richardson.

  • Finish support for targets with unusual float types, mapping target types to 32-, 64-, 80- and 128- bit picolibc code.

  • Add SuperH support, including testing infrastructure. Thanks to Adrian Siekierka for help with this.

  • Improve debugger stack trace in risc-v exception code. Thanks to Alex Richardson.

  • Add an option (-Dfast-bufio=true) for more efficient fread/fwrite implementations when layered atop bufio. Thanks for the suggestion from Zachary Yedidia.

  • Fix cmake usage of FORMAT_ variables (note the lack of a leading underscore).

  • Remove explicit _POSIX_C_SOURCE definition in zephyr/zephr.cmake.

  • Clean up public inline functions to share a common mechanism for using gnu_inline semantics. Fix isblank. This ensures that no static inline declarations exist in public API headers which are required to be external linkage ("real") symbols.

  • Create an alternate ctype implementation that avoids using the ctype array and just does direct value comparisons. This only works when picolibc is limited to ASCII. Applications can select whether they want this behavior at application compilation time without needing to rebuild the C library. Thanks to P. Frost for the suggestion.

  • Unify most fenv implementations to use gnu_inline instead of regular functions to improve performance. x86 was left out because those fenv functions are complicated by the mix of 8087 and modern FPU support.

  • Add a separate FILE for stderr when using POSIX I/O. Split stdin/stdout/stderr into three files to avoid pulling in those which aren't used. Thanks to Zachary Yedidia.
