2021-02-12string: add __mtag_tag_zero_regionSzabolcs Nagy
Add optimized __mtag_tag_zero_region(dst, len) operation to AOR. It tags the memory according to the tag of the dst pointer then memsets it to 0 and returns dst. It requires MTE support. The memory remains untagged if tagging is not enabled for it. The dst must be 16 bytes aligned and len must be a multiple of 16. Similar to __mtag_tag_region, but uses the zeroing instructions.

2021-01-08string: Assembly code cleanupWilco Dijkstra
Cleanup spurious .text and .arch. Use ENTRY rather than ENTRY_ALIGN.
2021-01-04string/test: Fix strrchr '\0' error reportRichard Henderson
The error report was copied from the seekchar test above, and needs adjustment to match the gating IF.
2021-01-04string: Reduce alignment in strncmpRichard Henderson
There were nops before the beginning of the function to place the main loop on a 64-byte boundary, but the addition of BTI and instructions for ILP32 has corrupted that. As per review, drop 64-byte alignment entirely, and use the default 16-byte alignment from ENTRY.
2021-01-04string: Replace explicit nops with alignmentRichard Henderson
These nops were placed to align code to 16-byte boundaries, but then the addition of BTI and ILP32 has corrupted that.
2021-01-04string: Fix strnlen return valueRichard Henderson
The comment on the eos-not-found path says that it is returning the max string length, but it actually uses the current string length. This results in returned values larger than the expected value.

2020-11-16v20.11 releaseSzabolcs Nagy
* New math routines * Scalar erff and erf using fma.
2020-11-13math: fix spurious underflow in erff and erfSzabolcs Nagy
The code relied on the final x + c*x to be done via an fma, otherwise the intermediate c*x could underflow for tiny (almost subnormal) x. Use explicit fmaf like elsewhere (this code is not expected to be fast when fma is not inlined, but at least it should be correct).
2020-11-13math: fix erf tests in directed rounding modesSzabolcs Nagy
erf has larger than 1 ULP errors in directed rounding modes, increase the error threshold to 1.4 ULP in the test script.
2020-11-13math: add scalar erfPierre Blanchard
Only tested in round-to-nearest mode. The expected worst case error is 1.01 ULP near x=1.25. Benchmarked over random x in [-6,6] and can increase performance by > 2x (> 3.5x for throughput) on big ooo cores compared to the implementation in glibc 2.28. Includes data for erfc too, but this patch only adds erf.
2020-11-05networking: Fix the copyright notice in chksum.cSzabolcs Nagy
Make the formatting consistent with other copyright notices. (This helps me doing automatic license header checks.)
2020-11-05math: Fix copyright header in erff.tstSzabolcs Nagy
This was incorrect in the previous commit.

2020-10-29math: add scalar erff.Pierre Blanchard
In round-to-nearest mode the maximum error is 1.09 ULP. Compared to glibc-2.28 erff: throughput is about 2.2x better, latency is about 1.5x better on some AArch64 cores (on random input in [-4,4]). There are further optimization and quality improvement opportunities.
