Description robert longhausen 2002-09-05 15:11:46 UTC

zlib-1.1.4 (and other versions) comes with assembly routines in the contrib
directory.  These are much faster than the default C code.  The ebuild doesn't
use these routines.

1.  Determine current system type (ie i386, i586, i686, or other)
2.  If we are building for a system type with assembly routine, copy the match.S
file from the contrib/asm* directory to the main directory
3.  configure with "-DASMV" added to the CFLAGS (for both shared and static)
4.  for static, "make OBJA=match.o"
5.  for shared, add "$(OBJA)" to "$(SHAREDLIB).$(VER): $(OBJS)" and to the next
line (lines 82 and 83), then "make OBJA=match.o"

I am guessing there is a reason why this is not done by default ?
Stability/whatnot issues?

The assembly stuff are not maintained, and I do not comfortable to add them.
