The fpfs function is using strtof to convert a string to floating point
value, but the type may be a double. Using strtof in that case won't
provide enough precision, so switch to using strtod. When the type is a
float, the double will be down-converted to the correct value.
C++17ification!
- Filesystem interaction now uses std::filesystem::path.
- Usage of const char*, std::string have been changed to
std::string_view where appropriate.
- Usage of printf-style functions changed to use fmt.
With GCC and clang, __m128 is not a struct, so there are no struct members
to access the individual items in the vector.
Use standard load/store function and some hackery to workaround this
limitation.
Lots of bugs/rough edges/etc - issues will be filed.
Old-style debugging still works (just use --emit_source_annotations to get
the helpful movs back and --break_on_instruction will still fire).
