These can already be visualised in source or on github.

No need to maintain 2 changelogs.
Besides, the actual changelog is behind the one on the website.
Just keep CHANGELOG.md updated and remove the other one.

Add a table for supported compilers and OS-es.
Add badges linked to CI, License and SLEEF paper, Spack package, ...
Update install and build instructions.

Keep toolchain files and rename them.

fix in libm and quad

This is a follow up from #454.

Individual COMMANDS in define_custom_command are not guaranteed to
execute sequentially, meaning that the inline headers may be broken if
doing a parallel build with make. Each command is extracted into its
own custom_command (some are merged, such as subsequent sed calls) so
that CMake can properly make sense of the dependencies and generate
consistent headers in parallel.

* Atomise creation of inline header, alias, dispscalar, simd disp, sleefquad header and build
* Reuse existing atomic inline libm header generation for CUDA

Now that custom_commands are atomic, parallel builds should be
supported with make.

* Use CMake cat instead of shell cat

This requires minimum CMake 3.18, which is not particularly
recent. This provides a better cross-platform way of concatenating
files.

Removes warnings about deprecation of old API for versions of OpenSSL above 3.0.
Needed to amend openssl static link line to avoid a crash in tester3 with old openssl.
Fixes #486.

This is sometimes defined in math.h.

These two functions were added to the MPFR API.
Fixes #458.

* Add support for the RISC-V Vector ISA
- RISC-V V 1.0 with (latest) intrinsics >=0.12.
- Enable bit manip extensions on RISC-V.
- Add RVVM*NOFMA configurations for determinism/bit-reproducibility across all architectures.

* Not supported yet
- DFT, QUAD, and GNUABI.
- Only upcoming versions of gcc (14+) have support for latest intrinsics. Will be supported when available in release version of gcc.

* CI Updates
- Add riscv64 CI on GitHub Actions.
- Add gcc (11 - #483) and llvm (17) builds on all architectures.
- Disable a few failing test variants, tracked in #484 and #485.
- Use same compiler versions across all builds.
- Add sysroot for dependencies.
- Nit: Reorder build-cross targets to group gcc/llvm per-arch together.

* Use variables from GNUInstallDirs everywhere

* Componentize the install rules

* Add headers to the interface include path

* Add install rules for CMake package config

* Associate inline headers to a target

Previously inline_headers was a UTILITY target, which cannot be
installed, so it was renamed to inline_headers_util and a new
inline_headers INTERFACE library target is introduced instead.

This is yet another patch for cleaning up the code.
It mainly removes warning messages generated when compiling gnuabi_compatibility.c.
It unifies the code for detecting availability of vector extensions.
It removes unused variables.
It adds mveclibtest.c that tests if substitution of mveclib with sleefgnuabi works.

This patch adds OpenMP simd pragmas to more scalar functions.
It also adds more testing to check if the functions can be auto-vectorized.

With this patch, libm functions and libquadmath functions can be replaced with sleef functions by defining SLEEF_REPLACE_LIBM_FUNCS and SLEEF_REPLACE_LIBQUADMATH_FUNCS macros before including sleef.h and sleefquad.h, respectively. The replaced libm functions can be automatically vectorized with gcc on x86_64.

This patch adds vector ABI aliases to the vector functions.
It also adds "omp declare simd" pragma to the declaration of scalar functions in sleef.h.
This pragma is only enabled if SLEEF_ENABLE_OMP_SIMD is defined.
By the modifications above, the auto-vectorizer in gcc can convert calls to sleef scalar functions to the corresponding vector functions.

With this patch, the scalar functions implemented in sleefdp.c and sleefsp.c will be included in libsleefscalar.
The functions with the same names in libsleef will be aliases to the dispatcher added in PR #402.
By modifying like this, the scalar functions will run faster on computers with FMA support.

This patch adds a dispatcher to the main library.

This patch drops CI testing at Travis.
Testing for PPC64 and System/390 will be carried out on Jenkins.

This patch cleans up the dispatcher to remove duplicated code.

This patch adds a dispatcher for 128-bit wide vector functions in the quad library.

This patch adds a dispatcher for the scalar functions in the quad library.

With this patch, the inline headers can be generated with MinGW.
This patch also enables CI testing on MinGW build.

This is a combined patch including the following items.

* Define quad-precision constants in the header files
* Add macros for libquadmath compatibility
* Remove unions from helperpurec_scalar.h. Unions are removed from sleefquadinline_cuda.h, as a result.

With this patch, the pure C inline header can be included from CUDA programs along with the CUDA inline header.

This is a combined patch for eliminating most of the warning messages.

This is a combined patch for removing potential problems with the strict aliasing rule.
It also drops long double support for DFT.

With this patch, `-fno-tree-vrp` compiler option is added if the SVE code is compiled with GCC.

This patch adds support and build-only testing for iOS.
ios.toolchain.cmake is required for building, which can be downloaded from at https://github.com/leetal/ios-cmake
