Move to assembly 2006-02-07T17:24:14+00:00 Jack Steiner steiner@sgi.com 2006-02-07T17:24:14+00:00 urn:sha1:dcc1dd2366a7c355fd8b6543c52685b864a2044f Rewrite the SN pio_phys_xxx macros in assembly language. This avoids issues with the Intel icc compiler. Function call overhead is not an issue - the functions reference PIOs and take 100's nsec to complete. In addition, the functions should likely be in assembly language anyway - they reference memory using physical addressing mode. One function executes with psr.ic disabled.
