-notrigraph Option |
 |
This option inhibits the processing of trigraphs. The -notrigraph option, in previous versions, caused the legacy preprocessor
to be invoked, which ignored trigraphs. These trigraphs were still
interpreted by the compiler in the preprocessed source.
In this version, the -notrigraph option does not invoke the legacy preprocessor and also suppresses
the trigraphs from being interpreted.
This option is not recommended. The proper portable solution
is to quote the "?" as "\?".
NO_SIDE_EFFECTS Pragma |
|
This pragma states that functionname and all the functions that functionname calls will not modify any of a program’s local
or global variables. This pragma provides additional information
to the optimizer which results in more efficient code.
Syntax:
#pragma NO_SIDE_EFFECTS functionname,..., functionnameN
Example:
#pragma NO_SIDE_EFFECTS foo
// where foo is name of a function. |
