Options for Controlling the C Dialect
Option
C DIALECT CONTROL OPTIONS
Support all (and only) ANSI-standard C programs.
Output to the given filename prototyped declarations for all
functions declared and/or defined in a translation unit,
including those in header files. This option is silently
ignored in any language other than C. Besides
declarations, the file indicates, in comments, the origin of
each declaration (source file and line), whether the
declaration was implicit, prototyped or unprototyped (I, N
for new or O for old, respectively, in the first character after
the line number and the colon), and whether it came from a
declaration or a definition (C or F, respectively, in the
following character). In the case of function definitions, a
K&R-style list of arguments followed by their declarations is
also provided, inside comments, after the declaration.
Assert that compilation takes place in a freestanding
environment. This implies -fno-builtin. A freestanding
environment is one in which the standard library may not
exist, and program startup may not necessarily be at main.
The most obvious example is an OS kernel. This is
equivalent to -fno-hosted.
Do not recognize asm, inline or typeof as a keyword,
so that code can use these words as identifiers. You can
use the keywords
__
-ansi implies -fno-asm.
Don't recognize built-in functions that do not begin with
__
Let the type char be signed, like signed char.
(This is the default.)
These options control whether a bit field is signed or
unsigned, when the declaration does not use either signed
or unsigned. By default, such a bit field is signed, unless
-traditional is used, in which case bit fields are always
unsigned.
Let the type char be unsigned, like unsigned char.
Store strings in the writable data segment and don’t make
them unique.
typeof
builtin_ as prefix.
