thorpej	201e41fc31	* Rename "word" -> 16, and "long" -> 32, as suggested by Ben Harris. * Replace __byte_swap_32_variable() with a C version from Richard Earnshaw that generates nearly identical assembly (and it would be exactly identical with the addition of another peephole to GCC ARM back-end).	2002-08-14 15:08:57 +00:00
thorpej	da5ef20b1a	Byte-swapping optimizations, enabled if compiling with GCC: * Byte-swap 16-bit and 32-bit constants at compile-time. * Inline 16-bit and 32-bit variable byte-swaps. These take 3 and 4 insns, respectively, and inlining saves the minimum 6 cycle penalty to call/return from the byte swap function.	2002-08-13 22:41:36 +00:00

* Rename "word" -> 16, and "long" -> 32, as suggested by Ben Harris.

* Replace __byte_swap_32_variable() with a C version from Richard
  Earnshaw that generates nearly identical assembly (and it would be
  exactly identical with the addition of another peephole to GCC ARM
  back-end).

Byte-swapping optimizations, enabled if compiling with GCC:

* Byte-swap 16-bit and 32-bit constants at compile-time.
* Inline 16-bit and 32-bit variable byte-swaps.  These take 3 and 4
  insns, respectively, and inlining saves the minimum 6 cycle penalty
  to call/return from the byte swap function.

Header files which don't differ between arm32 and arm26 and can thus be

shared.
