Description:
picolibc-aarch64-linux-gnu - Smaller embedded C library for 64-bit ARM development
picolibc-arm-none-eabi - Smaller embedded C library for ARM development
picolibc-riscv64-unknown-elf - Smaller embedded C library for RISC-V development
picolibc-xtensa-lx106-elf - Smaller embedded C library for ESP8266 development
Changes:
picolibc (1.4.7-1) unstable; urgency=medium
.
* New upstream version
.
* Fix numerous libm exception and errno bugs. The math functions are
all now verified to match the C19 and Posix standards in this
area.
.
* Change behavior of 'gamma' function to match glibc which returns
lgamma for this function. Applications should not use this
function, they should pick either lgamma or tgamma as appropriate.
.
* Fix fma/fmaf on arm and RISC-V so that the machine-specific
versions are used when the hardware has support. Also fix the math
library to only use fma/fmaf when it is supported by the hardware.
.
* Fix numerous nano-malloc bugs, especially with unusual parameters.
.
* Change nano-malloc to always clear returned memory.
.
* Improve nano-realloc to perform better in various ways, including
merging adjacent free blocks and expanding the heap.
.
* Add malloc tests, both a basic functional test and a stress test.
.
* Improve build portability to Windows. Picolibc should now build
using mingw.
.
* Use hardware TLS register on ARM when available.
.
* Support clang compiler. Thanks to Denis Feklushkin
<denis.feklushkin@gmail.com> and Joakim Nohlgård
<joakim@nohlgard.se>.
.
* Avoid implicit float/double conversions. Check this by having
clang builds use -Wdouble-promotion -Werror=double-promotion flags
.
* Have portable code check for machine-specific overrides by
matching filenames. This avoids building libraries with duplicate
symbols and retains compatibility with newlib (which uses a
different mechanism for this effect).
.
* Patches to support building with CompCert
(http://compcert.inria.fr/), a formally verified compiler. Thanks
to Sebastian Meyer <meyer@absint.com>.
