picolibc (1.4.7-1.1) unstable; urgency=medium
* Non-maintainer upload.
* source only upload to enable migration (Closes: #978412)
-- Paul Gevers <elbrus@debian.org> Sun, 27 Dec 2020 07:22:17 +0100
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>.

picolibc (1.4.6-2) unstable; urgency=medium
* Add aarch64-linux-gnu target
-- Keith Packard <keithp@keithp.com> Mon, 03 Aug 2020 14:03:51 -0700
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.
-- Keith Packard <keithp@keithp.com> Mon, 03 Aug 2020 11:47:08 -0700
picolibc (1.4.5-1) unstable; urgency=medium
* Fix section order in picolibc.ld to give applications correct
control over the layout of .preserve, .init and .fini regions.
* Add startup and TLS support for aarch64 and non Cortex-M 32-bit
arm.
-- Keith Packard <keithp@keithp.com> Sun, 28 Jun 2020 15:34:19 -0700
picolibc (1.4.4-1) unstable; urgency=medium
* New upstream 1.4.4
* Fix printf 'g' output when using 'ryu' conversion code
* Add fenv for ARM from newlib
-- Keith Packard <keithp@keithp.com> Wed, 10 Jun 2020 16:06:11 -0700
picolibc (1.4.3-1) unstable; urgency=medium
* New upstream version 1.4.3
* Make fix for CVE 2019-14871 - CVE 2019-14878 in original newlib
stdio code not call 'abort'. Allocation failures are now reported
back to the application.
* Add 'exact' floating point print/scan code to tinystdio. Thanks
to Sreepathi Pai for pointing me at the Ryu code by Ulf
Adams.
* Add regular expression functions from newlib. These were removed
by accident while removing POSIX filesystem-specific code.
* Make tinystdio versions of [efg]cvt functions. This means that the
default tinystdio version of picolibc no longer calls malloc from
these functions.
* More clang-compatibility fixes. (Thanks to Denis Feklushkin)
* Remove stdatomic.h and tgmath.h. (they should not be provide by picolibc)
-- Keith Packard <keithp@keithp.com> Tue, 09 Jun 2020 12:45:58 -0700
picolibc (1.4.2-3) unstable; urgency=medium
* Move lx106 bits back to original location
-- Keith Packard <keithp@keithp.com> Wed, 03 Jun 2020 12:05:15 -0700
picolibc (1.4.2-2) unstable; urgency=medium
* Remove aarch64 support to avoid hitting NEW queue
-- Keith Packard <keithp@keithp.com> Thu, 21 May 2020 11:20:07 -0700
picolibc (1.4.2-1) unstable; urgency=medium
* Clang source compatibility. Clang should now be able to compile
the library.
* Testing on github on push and pull-request. For now, this is
limited to building the library due to a bug in qemu.
* Get newlib stdio working again. You can now usefully use newlib's
stdio. This requires a working malloc and is substantially larger
than tinystdio, but has more accurate floating point input. This
requires POSIX functions including read, write and a few others.
* Fix long double strtold. The working version is only available
when using tinystdio; if using newlib stdio, strtold is simply not
available.
* Improve tinystdio support for C99 printf/scanf additions.
* Check for correct prefix when sysroot-install option is
selected. The value of this option depends on how gcc was
configured, and (alas) meson won't let us set it at runtime, so
instead we complain if the wrong value was given and display the
correct value.
* Sync up with current newlib master
* Add aarch64-linux-gnu support
-- Keith Packard <keithp@keithp.com> Thu, 21 May 2020 08:51:37 -0700

-- Keith Packard <keithp@keithp.com> Sat, 18 Apr 2020 14:56:40 -0700
picolibc (1.4.1-1) unstable; urgency=medium
* ARM TLS corruption fix
* Compilation compatibility fixes
* Add -msave-restore to RISC-V version
-- Keith Packard <keithp@keithp.com> Mon, 09 Mar 2020 12:02:54 -0700
picolibc (1.4-1) unstable; urgency=medium
* Merge upstream license changes from BSD 4-clause to BSD 3-clause
* Add copyright information where missing
* Create debian/copyright file automatically by perusing source files
-- Keith Packard <keithp@keithp.com> Tue, 04 Feb 2020 23:07:07 -0800
picolibc (1.3-1) unstable; urgency=medium
* New upstream release (1.3)
* Add testing
* Add lx106 binary package for xtensa-lx106-elf
* Fix some RISC-V ABI issues
-- Keith Packard <keithp@keithp.com> Tue, 31 Dec 2019 23:44:40 -0800

* New upstream release (1.2.1)
* Switch back to __OBSOLETE_MATH for machines without hw double
* Include realloc and mallinfo in the library
* Use SYS_EXIT on semihost implementations without SYS_EXIT_EXTENDED
-- Keith Packard <keithp@keithp.com> Mon, 02 Dec 2019 20:55:24 -0800
picolibc (1.2-1) unstable; urgency=medium

picolibc (1.1-2) unstable; urgency=medium
* Make install depend on compilers so .specs files work afterwards
-- Keith Packard <keithp@keithp.com> Fri, 15 Nov 2019 17:00:46 -0800
picolibc (1.1-1) unstable; urgency=medium
* Upstream release 1.1
* semihost support
* Posix I/O support on Posix systems
* Merged newlib code
* Hello world example
-- Keith Packard <keithp@keithp.com> Thu, 14 Nov 2019 17:01:13 -0800
picolibc (1.0-1) unstable; urgency=medium
