2023-01-24pl/math: Fix a copyright notice for consistencySzabolcs Nagy

Scripted copyright year updates based on git committer date.
2023-01-24string: Improve SVE memcpyWilco Dijkstra
Improve SVE memcpy by copying 2 vectors. This avoids a check on vector length and improves performance of random memcpy.
2023-01-23pl/math: Reduce order of single-precision tan polynomialJoe Ramsay
For both vector and scalar routines we reduce the order from 6 to 5. For vector routines, this requires reducing RangeVal as for large values the tan polynomial is not quite accurate enough. However the cotan polynomial is used in the inaccurate region in the scalar routine, so this does not need to change. Accuracy of scalar routine is unchanged. Accuracy in both vector routines is now 3.45 ULP, with the same worst-case.
2023-01-19pl/math: Add vector/Neon tanJoe Ramsay
New routine uses a similar technique to the single-precision Neon routine, but with an extra reduction to pi/8 using the double-angle formula. It is accurate to 3.5 ULP.
2023-01-10string: Compile memcpy-sve.S for aarch64 if compiler supports itJake Weinstein
This is a partial revert of b7e368fb. If SVE assembly is guarded by __ARM_FEATURE_SVE, it cannot build when SVE is not enabled by the build system. This is ok on AOR, but because Android (bionic) uses ifuncs to select the appropriate assembly at runtime, these need to compile regardless of if the target actually supports the instructions. Check for AArch64 and GCC >= 8 or Clang >= 5 so that SVE is not used on compilers that do not support it. This condition will always be true on future builds of Android for AArch64.
2023-01-10string: Optimize strcpyWilco Dijkstra
Optimize strcpy main loop - large strings are ~22% faster.
2023-01-10string: Improve strrchr-mteWilco Dijkstra
Use shrn for narrowing the mask which simplifies code. Unroll the strchr search loop which improves performance on large strings.
2023-01-09pl/math: Fix benchmark entries for SVE bivariate functionsPierre Blanchard
Variant was wrongly set in structures used to benchmark SVE functions. Before this change only half of the lanes were set as expected. Also reformat for ease of reading.
2023-01-06pl/math: Update copyright yearsJoe Ramsay
All files in pl/math updated to 2023.
2023-01-05Rewrite two abs masks as literalsJoe Ramsay
These were technically undefined behaviour - they have been rewritten without the shift so that their type is unsigned int by default.
2023-01-05pl/math: Add vector/Neon acoshJoe Ramsay
New routine is based on a vector implementation from log1p, which has been reused (with some modification for improved accuracy close to 0) from Neon atanh. Accurate to 3.5 ULP.
2023-01-05pl/math: Add vector/Neon acoshfJoe Ramsay
New routine uses inlined log1pf helper, and is accurate to 3.1 ULP (2.8 ULP if fp exceptions are enabled).
2023-01-05pl/math: Add scalar & vector/Neon tanhJoe Ramsay
New routines use the same algorithm, reliant on a modified version of expm1, and are accurate to 3 ULP.
2022-12-30pl/math: Add vector/SVE log2Pierre Blanchard
The new SVE implementation is a direct port of Neon log2, and is accurate to 2.58 ULPs. Update error threshold and comments for Neon log2 too, new approximate argmax but same threshold.
2022-12-30pl/math: Add vector/SVE log2fPierre Blanchard
New SVE routine is an SVE port of the Neon algorithm and is accurate to 2.48 ULPs.
2022-12-22pl/math: Add scalar & vector/Neon atanhJoe Ramsay
New routines are both based on existing log1p routines. Scalar is accurate to 3 ULP, Neon to 3.5 ULP. Both set fp exceptions correctly regardless of build config.
2022-12-22pl/math: Add scalar atan and set fenv in Neon atanJoe Ramsay
The simplest way to set fenv in Neon atan is by using a scalar fallback for under/overflow cases, however this routine did not have a scalar counterpart so we add a new one, based on the same algorithm and polynomial as the vector variants, and accurate to 2.5 ULP. This is now used as the fallback for all lanes, when any lane of the Neon input is special.
2022-12-22pl/math: Fix fp exceptions in Neon sinhf and sinhJoe Ramsay
Both routines previously relied on the vector expm1(f) routine exposed by the library, which depended on WANT_SIMD_EXCEPT for its fenv behaviour, however both routines were expected to always trigger fp exceptions correctly. To remedy this, both routines now use an inlined helper for expm1 (reused from vector tanhf in the case of sinhf), and special-case small input as well as large when WANT_SIMD_EXCEPT is enabled.
2022-12-20Correct exit code from runulp.shJoe Ramsay
The pipe prevented FAILs and PASSs being counted properly - the while read loop has been rewritten without a pipe, as it was prior to the changes here. fenv checking is temporarily disabled in Neon sinh and sinhf, as they do not get it right. This will be re-enabled once they have been fixed.
2022-12-20pl/math: Update ULP threshold for SVE erfPierre Blanchard
Updated comment and test threshold.
2022-12-20pl/math: Add scalar atanf and set fenv in Neon atanfJoe Ramsay
The simplest way to set fenv in Neon atanf is by using a scalar fallback to under/overflow cases, however this routine did not have a scalar counterpart so we add a new one, based on the same algorithm and polynomial as the vector variants, and accurate to 2.9 ULP. This is now used as the fallback for all lanes, when any lane of the Neon input is special.
2022-12-20pl/math: Add scalar & vector/Neon cbrtJoe Ramsay
New routines use the same algorithm, with simplified argument reduction and recombination in the vector variant. Both are accurate to 2 ULP.
2022-12-19pl/math: Update ULP threshold for Neon asinhJoe Ramsay
New max observed - updated filenames, comments and runulp threshold.
2022-12-19pl/math: Replace WANT_ERRNO with WANT_SIMD_EXCEPT for Neon fenvJoe Ramsay
We were previously misusing the WANT_ERRNO build flag. This is now replaced everywhere appropriate with WANT_SIMD_EXCEPT. A small number of vector routines get fp exceptions right with no modification - the tests have been updated to track this.
2022-12-19pl/math: Improve vector/Neon log2fPierre Blanchard
A new implementation based on the same approach as Neon logf, that is accurate to 2.48 ULPs. Flags set correctly regardless of WANT_ERRNO.
2022-12-15pl/math: Move test intervals to routine source filesJoe Ramsay
To conclude the work on simplifying the runulp.sh script, a new macro has been introduced to specify the intervals in which a routine should be tested in the routine source. This is eventually consumed by runulp.sh.
2022-12-15pl/math: Move fenv expectations out of runulp.shJoe Ramsay
Introduces a new macro, similar to how ULP thresholds are now handled, that emits a list of routines which are expected to correctly trigger fenv exceptions, to be consumed by runulp.sh. All scalar routines are expected to do so. A small number of Neon routines are also expected to, dependent on WANT_ERRNO.
2022-12-15pl/math: Move ULP limits to routine source filesJoe Ramsay
Introduces a new set of macros and Make rules for mechanically generating a list of ULP limits for each routine, to be consumed by runulp.sh. This removes the need to maintain long lists of thresholds in runulp.sh.
2022-12-15pl/math: Auto-generate mathbench and ulp headersJoe Ramsay
Instead of maintaining three separate lists of routines, which are cumbersome and prone to merge conflicts, we provide a new macro, PL_SIG, which by some preprocessor machinery outputs the lists in the required format (macro formats have been changed very slightly to make the generation simpler). Only routines with simple signatures are handled - binary functions still need mathbench wrappers defined manually. As well, routines with non-standard references (i.e. powi/powk) still need entries and wrappers manually defined.

2022-12-09pl/math: Add polynomial helpersJoe Ramsay
Add macros for simplifying polynomial evaluation using either Horner, pairwise Horner or Estrin. Several routines have been modified to use the new helpers. Readability is improved slightly, and we expect that this will make prototyping new routines simpler.
