Subject: [openrisc] [or1ksim #4] Store instruction function unit in or32.c
Hi,This patch stores the functional unit that the instruction is in in or32.c
rather than setting it in *every* instruction executed, wether it is needed or
not.
I don't know how to clasify the vector instructions so I just used it_unknown.
Whenever they get implemented then they can be corrected. The double precision
floating point instructions I just clasified as it_float, again this can be
corrected when they get implemented. The rotate instructions I clasified as
it_shift. The rest stayed as they were in the origional code.
In l_invalid there was this comment:
/* It would be hard to handle this case for statistics; we skip it
since it should not occur anyway:
IFF (config.cpu.dependstats) current->func_unit = it_unknown; */
The comment is rather misleading as iqueue gets cleared, thus setting
current->func_unit to 0, which just happens to be it_unknown.
ChangeLog:
* Avoid doing a store in *every* instruction executed by storeing the
instruction function unit in or32_opcodes.
nog.
