[Markus Deuling <deuling@de.ibm.com>]

[-- Attachment #1: Type: text/plain, Size: 399 bytes --]

Hi,

this patch replaces and removes DEPRECATED_STREQN. Testsuite showed no regressions.

Is this ok to commit ? 


ChangeLog:

	* jv-exp.y (yylex): Replace DEPRECATED_STREQN with the appropriate
	function calls.
	* m2-exp.y (yylex): Likewise.
	* objc-exp.y (yylex): Likewise.

	* defs.h (DEPRECATED_STREQN): Remove.

-   While old code can continue to refer to these macros, new code is
-   probably better off using strcmp() directly vis: ``strcmp() == 0''

-   This is because modern compilers can directly inline strcmp()

-   call overhead by pre-testing the first characters
-   (``*X==*Y?...:0'') - redundant.
-
-   ``Even if [...] testing the first character does have a modest
-   performance improvement, I'd rather that whenever a performance
-   issue is found that we spend the effort on algorithmic
-   optimizations than micro-optimizing.'' J.T. */

-   making untested changes, the remaining references were deprecated
