Subject: [musl] [C23 128 bit 0/4] implement the library part of 128 bit support
Date: Wed, 31 May 2023 16:15:46 +0200	[thread overview]
Message-ID: <cover.1685536608.git.Jens.Gustedt@inria.fr> (raw)

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
