gh-108562: Fix compiler warnings for libmpdec (#114751) 
If awailable, enable -fstrict-overflow for libmpdec. Also
shut off false positive warnings (-Warray-bounds).

The later was backported from mpdecimal-4.0.0.

gh-77532: Minor tweaks to allow compiling with PlatformToolset=ClangCL on Windows (GH-101352) 
To use this, ensure that clang support was selected in Visual Studio Installer, then set the PlatformToolset environment variable to "ClangCL" and build as normal from the command line.
It remains unsupported, but at least is possible now for experimentation.

bpo-40878: xlc cannot handle C99 extern inline. (GH-21887) 
This applies to the default "extc99" mode.  Python does not compile with "stdc99".

bpo-41302: Fix build with system libmpdec (GH-21481) 
Move definition of UNUSED from modified headers of libmpdec to
_decimal.c itself. This makes the vendored source closer to the
standalone library and fixes build with --with-system-libmpdec.

Tested to build fine with either system libmpdec or the vendored one.

bpo-35059, libmpdec: Add missing EXTINLINE in mpdecimal.h (GH-10128) 
Declare functions with EXTINLINE:

* mpd_del()
* mpd_uint_zero()
* mpd_qresize()
* mpd_qresize_zero()
* mpd_minalloc()

These functions are implemented with "inline" or "ALWAYS_INLINE", but
declared without inline which cause linker error on Visual Studio in
Debug mode when using /Ob1.

Stefan Krah 45059eb1d0 1) Prepare libmpdec for the 2.4.0 release. None of the following changes affects 
_decimal:

      o Make all "mpd_t to C integer" conversion functions available in both the
        64-bit and the 32-bit versions.

      o Make all mixed mpd_t/C integer arithmetic functions available in the
        32-bit version.

      o Better handling of __STDC_LIMIT_MACROS for C++ users.

      o Add struct tags (at the request of C++ users).

2) Check for libmpdec.so.2 if --with-system-libmpdec is used.

Stefan Krah f21587e3a8 mpd_qpowmod(): calculate result with zero-exponent for compatibility with

 2012-08-23 15:05:29 +02:00
Stefan Krah 2fd502f6a1 1) Use _mpd_basedivmod() regardless of the length of the dividend. This is 
required for a corner case in dec_hash() in the following commit and also
   usually faster. dec_hash() needs some extra precision above MPD_MAX_PREC,
   and _mpd_base_ndivmod() is not audited for that.

2) Use _mpd_basemul() if the length of the smaller operand is less than
   or equal to 256. While this is technically an optimization, it is
   required for *testing* corner cases in dec_hash() in reasonable time.

Stefan Krah 5431e30853 After 79d2eb29c755 it is no longer necessary to zero the output array: 
None of the _mpd_shortadd() or _mpd_shortmul() functions read uninitialized
values. Previously zeroing was required since _mpd_real_size() was called
on the output array.

Stefan Krah c35a8e5c98 Proactive reliability fix for broken FPUs: The base conversion functions 
use log10() to calculate the size of the output array. The current code
has been tested on x86/amd64 (and to a lesser extent on qemu-mips qemu-sparc)
and produces sufficiently large values for all inputs tested so far (coefficient
sizes of 10**18 - 1 are hard to test exhaustively).

The new code does not rely on the correctness of log10() and resizes
the output arrays if the allocated space is insufficient.
