#include <machine/asm.h> instead of "DEFS.h"
1997-01-04 03:26:18 +00:00
48030a80ae
Use jCC instead of bCC, as the assembler will then use the (smaller,
...
faster) byte-displacement form of the instruction if the offset will
fit. This happens to be all occurances in this case, so I could have
used bCCs. However, a quick survey of the rest of NetBSD's m68k code
showed that jCC was used in similar cases. I did the same to be
consistant.

memory regions are "potentially overlapping" to a test that determines

improves performance in the average case.

Change instances of LIBC_RCS back to LIBC_SCCS. If we are going to change
...
th LIBC_RCS, the entire source tree should be updated at once.
Remove && !defined(lint) from conditionals around rcs id's. No one is
ever going to pass a *.s file through lint.

Replaced instructions with immediate operands with compatible alternatives
...
saving a few bytes while the cycle count remains the same --- could
actually be faster, depending on the cache, prefetch queue, etc.

First cut; not sure if it's right. Very like it is, because it's
...
the same as the m68k versions..

Provide i386 versions of div and ldiv -- they are simpler than the C versions,
...
since the idiv instruction does the right thing wrt truncating towards zero.

Use "testb %cl,%cl" instead of "cmpb $0,%cl".
...
This saves three cycles per character, and reduces the size of the
function by eight bytes (the loop is unrolled eight times).
Thanks to davidg for pointing this out.

Provide an assembly language version of labs().
...
Since ints and longs are both 32 bits on a i386, we could alias abs()
and labs() together as mycroft did with memmove()/memcpy(), but I'm
waiting on an interpretation ruling to see if it is legal.
