Author: sginsberg Date: Tue Aug 4 13:22:50 2009 New Revision: 42378 URL: http://svn.reactos.org/svn/reactos?rev=42378&view=rev Log: - Remove asm-optimized versions of RtlRandom and RtlUniform -- there is *no* reason to use hand-optimized assembly for simple routines like these -- let the compiler do its job, please. Also, we compiled random.c *and* random_asm.S, meaning we duplicated the functions -- the compiler didn't detect this and silently used the C versions. - Don't forward RtlRandomEx to RtlRandom in ntdll -- RtlRandomEx should use a different algorithm (but is simply a copy of RtlRandom right now). - Revert RtlUniform back to the "slow" version -- let the compiler do its job instead of obfuscating code for a miniscule speed gain.
