CI through Github Actions

4

in #257 it was proposed a next step was to do CI through Github Actions. I propose we do a single build with MSVC, then build the libraries, then build...

Investigate slow compiles

2

three files in the suite compile especially slowly: sqlite3.c ilstream.cpp ilunstream.cpp investigate why

Optimize register usage in loops

2

when for-range is used for example on vectors, the resulting code generation is somewhat awful. Loop handling for tight loops would work better if the reference optimizations were optimized away...

add filesystem header back into libcxx

1

add filesystem header into libcxx as part of the C++17 update

improve stack frame generation

2

clang modifies the push/pop model for function call stack frames to instead allocate the maximum stack frame needed for all function calls within a function body, then never do push/pops...

autoconfig work

15

get the latest versions of libgmp and libmpfr; run the libgmp tests; use an occ-generated version of libgmp (and possibly other libraries) when running libcob and libmpfr...

Research whether anything can be done about EXE size.

8

the OCC compiled binaries are significantly larger than binaries compiled by other compilers. This *may* be because the linker doesn't do a good job of filtering unused virtual sections. Research...

Support C++20

3

Support the C++20 extensions to c++.

Function alignment optimization

1

on x86, aligning functions on 16-byte boundaries can improve the speed. Make this a speed improvement.

Optimizer - optimize branches for branch prediction

8

minimize branches and generally ease the way for branch prediction in the later pentiums to result in faster code...
