2022-02-10	Update lincense to MIT OR Apache-2.0 WITH LLVM-exception	Szabolcs Nagy
	The outgoing license was MIT only. The new dual license allows using the code under Apache-2.0 WITH LLVM-exception license too.
2021-02-17	Update copyright years	Szabolcs Nagy
	Scripted copyright year updates based on git committer date.
2020-11-13	math: add scalar erf	Pierre 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.
2020-11-05	math: Fix copyright header in erff.tst	Szabolcs Nagy
	This was incorrect in the previous commit.
2020-10-29	math: 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.
2019-07-22	Reorganize the directory layout	Szabolcs Nagy
	To allow subprojects other than math, the build system and directory layout is changed: all math related code, tools and tests are under the math directory now, new subprojects should be similarly self- contained. The top level Makefile design is still kept, but the subproject build directories provide their own Dir.mk with the build rules for the subproject. The user interface of config.mk is kept for now, in the future subproject specific flags and make variables may be added for finer grained control.
