Subject: [C23 128 bit 0/4] implement the library part of 128 bit support
This does not implement full featured support for 128 bit types or
functions. It only enables the support that is necessary, such that
compilers can claim [u]int128_t types and their functionality.
All 128 types and arithmetic has to be provided by the compilers.
Jens Gustedt (4):
add an emulation for 128 bit arithmetic as needed for C library
support
C23: implement w128 and wf128 support for printf
C23: implement w128 and wf128 for scanf and similar
C23: implement proper support for int128_t and uint128_t
