◆ error()

void error ( const char * format,
... )
extern
A hard error: the code is definitely ill-formed, and an object file
will not be produced.   
Print an error message - we keep going but the output is unusable.

◆ fatal()

◆ internal_error()

void internal_error ( const char * format,
... )
extern
An internal consistency check has failed.  We make no attempt to
continue.   
Similar, but say we got an internal error.

◆ trim_filename()

const char * trim_filename ( const char * name)
extern
Given a partial pathname as input, return another pathname that
shares no directory elements with the pathname of __FILE__.  This
is used by fancy_abort() to print `internal compiler error in expr.cc'
instead of `internal compiler error in ../../GCC/gcc/expr.cc'.   
Given a partial pathname as input, return another pathname that
shares no directory elements with the pathname of __FILE__.  This
is used by fancy_abort() to print `Internal compiler error in expr.cc'
instead of `Internal compiler error in ../../GCC/gcc/expr.cc'.  This
version is meant to be used for the gen* programs and therefor need not
handle subdirectories.

◆ warning()

void warning ( const char * format,

warning, error, and fatal.  These definitions are suitable for use
in the generator programs; eventually we would like to use them in
cc1 too, but that's a longer term project.

N.B. We cannot presently use ATTRIBUTE_PRINTF with these functions,
because they can be extended with additional format specifiers which
GCC does not know about.   
Print a warning message - output produced, but there may be problems.
