Changelog
picolibc (1.4.6-1) unstable; urgency=medium
* New upstream version
* Install 'ssp' (stack smashing protection) header files. This fixes
compiling with -D_FORTIFY_SOURCE.
* Make getc/ungetc re-entrant. This feature, which is enabled by
default, uses atomic instruction sequences that do not require
OS support.
* Numerous iconv fixes, including enabling testing and switching
external CCS file loading to use stdio. By default, iconv provides
built-in CCS data for all of the supported encodings, which takes
a fairly large amount of read-only memory. Iconv is now always
included in picolibc as it isn't included in applications unless
explicitly referenced by them.
* Add __getauxval stub implementation to make picolibc work with
GCC version 10 compiled for aarch64-linux-gnu.
* Change how integer- and float- only versions of printf and scanf
are selected. Instead of re-defining the symbols using the C
preprocessor, picolibc now re-defines the symbols at link
time. This avoids having applications compiled with a mixture of
modes link in multiple versions of the underlying functions, while
still preserving the smallest possible integer-only
implementation.
* Document how to use picolibc on a native POSIX system for
testing. Check out the [os.md](doc/os.md) file for details.
* Merge current newlib bits in. This includes better fenv support,
for which tests are now included in the picolibc test suite.
