New Features in Version A.03.55
HP aC++ version A.03.55 supports the following new features:
• -notrigraph Option
• NO_SIDE_EFFECTS Pragma
-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.
