Last change on this file since 344 was 123, checked in by zap, 23 years ago

Started the work for re-designing the EMX C runtime library to not require
EMX.DLL. The new design is projected to be as follows:

  • all emx syscalls are replaced with the routines from the old sys.lib library which is now compilable in both a.out and OMF formats.
  • the sys.a library should be made replaceable and selectable by some gcc switch (e.g. -msyslib=emx would link with emx.a instead of sys.a which would give almost full backward compatibility with emx).
  • All C functions names were renamed to not contain the starting underscore (e.g. fopen and not _fopen). The underscored aliases will be added later with the c_alias library (which will be generated automatically from all public symbols of libc; any exported symbol that do not start with an underscore will be given an underscored alias unless such a symbol is already defined).

Also a lot of updates to the building system. It is now much faster (thanks
to Knut's suggestion of using ash's builtin echo).
Also re-wrote thunk1.asm and thunk2.asm to GAS format; this removes the need
for MASM and makes it possible to use 16-bit functions in a.out programs
without the need for EMX.DLL.
Also made a lot of small changes I don't remember now.
  • Property cvs2svn:cvs-rev set to 1.3
  • Property svn:eol-style set to native
  • Property svn:executable set to *
