- /* tccdefs.h
- Nothing is defined before this file except target machine, target os
- and the few things related to option settings in tccpp.c:tcc_predefs().
- This file is either included at runtime as is, or converted and
- included as C-strings at compile-time (depending on CONFIG_TCC_PREDEFS).
- Note that line indent matters:
- - in lines starting at column 1, platform macros are replaced by
- corresponding TCC target compile-time macros. See conftest.c for
- the list of platform macros supported in lines starting at column 1.
- - only lines indented >= 4 are actually included into the executable,
- check tccdefs_.h.
