* [3.9] bpo-41100: Support macOS 11 and Apple Silicon (GH-22855) (GH-23295)Ronald Oussoren2020-11-221-0/+3
| | | | | | | | | | | | | | | | | | | | * [3.9] bpo-41100: Support macOS 11 and Apple Silicon (GH-22855) Co-authored-by: Lawrence D’Anna <lawrence_danna@apple.com> * Add support for macOS 11 and Apple Silicon (aka arm64) As a side effect of this work use the system copy of libffi on macOS, and remove the vendored copy * Support building on recent versions of macOS while deploying to older versions This allows building installers on macOS 11 while still supporting macOS 10.9.. (cherry picked from commit 41761933c1c30bb6003b65eef1ba23a83db4eae4) Co-authored-by: Ronald Oussoren <ronaldoussoren@mac.com> * Back port of changes to _decimal to support arm64 * temp_dir is in test.support in 3.9
* bpo-40878: xlc cannot handle C99 extern inline. (GH-21891)Miss Islington (bot)2020-08-151-1/+1
| | | | | | | This applies to the default "extc99" mode. Python does not compile with "stdc99". (cherry picked from commit 40e700ad042089120456cc2ee79b8ca69479416b) Authored-by: Stefan Krah <skrah@bytereef.org>
* bpo-41302: Fix build with system libmpdec (GH-21481)Miss Islington (bot)2020-07-151-6/+0
| | | | | | | | | | 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. (cherry picked from commit 015efdbef7454a522e88cd79ba2b4cd77a5fb2a2) Co-authored-by: Felix Yan <felixonmars@archlinux.org>

* bpo-35059, libmpdec: Add missing EXTINLINE in mpdecimal.h (GH-10128)Victor Stinner2018-10-261-5/+5
| | | | | | | | | | | | | 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.

* Fix C++ header usage. This __STDC_LIMIT_MACROS scheme can still be subvertedStefan Krah2013-12-141-9/+11

* mpd_qpowmod(): calculate result with zero-exponent for compatibility withStefan Krah2012-08-231-15/+17
| | | | decimal.py. The hack to remove the ideal exponent is no longer required.
* 1) Use _mpd_basedivmod() regardless of the length of the dividend. This isStefan Krah2012-08-221-6/+9
| | | | | | | | | | 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.

* Issue #7652: Clean up _mpd_qinvroot() and mark it LIBMPDEC_ONLY. Use theStefan Krah2012-07-121-135/+140
| | | | algorithm from decimal.py for mpd_qsqrt().
* After 79d2eb29c755 it is no longer necessary to zero the output array:Stefan Krah2012-06-301-4/+4
| | | | | | 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.
* Proactive reliability fix for broken FPUs: The base conversion functionsStefan Krah2012-06-304-180/+389
| | | | | | | | | | 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.

* Many cleanups of redundant code in mpd_qrem_near():Stefan Krah2012-06-201-23/+15
| | | | | | | | | | | | | | | | | | 1) _mpd_qdivmod() uses the context precision only in two places, and the new code should be exactly equivalent to the previous code. 2) Remove misleading comment. 3) The quotient *is* an integer with exponent 0, so calling mpd_qtrunc() is pointless. 4) Replace two instances of identical code by a single one. 5) Use _mpd_cmp_abs() instead of mpd_cmp_total_mag(): the operands are not special. 6) Don't clear MPD_Rounded in the status (with the current code it should not be set within the function).
* Add comments to the power functions, in particular to _mpd_qpow_real().Stefan Krah2012-06-181-5/+34

* 1) State the relative errors of the power functions for integer exponents.Stefan Krah2012-06-161-2/+18
| | | | | | | | | | | | | | | 2) _mpd_qpow_mpd(): Abort the loop for all specials, not only infinity. 3) _mpd_qpow_mpd(): Make the function more general and distinguish between zero clamping and folding down the exponent. The latter case is currently handled by setting context->clamp to 0 before calling the function. 4) _mpd_qpow_int(): Add one to the work precision in case of a negative exponent. This is to get the same relative error (0.1 * 10**-prec) for both positive and negative exponents. The previous relative error for negative exponents was (0.2 * 10**-prec). Both errors are _before_ the final rounding to the context precision.
