| H A D | sb_scd.h | diff 203509 Fri Feb 05 01:26:09 MST 2010 neel Reimplement all functions to access the system control unit in C. The only reason we need to have the sb_load64() and sb_store64() functions in assembly is to cheat the compiler and generate the 'ld' and 'sd' instructions which it otherwise will not do when compiling for a 32-bit architecture. There are some 64-bit registers in the SCD unit that must be accessed using 64-bit load and store instructions. |
