Re: request u provide me a solution in my linear assembly.

Started by Jeff Brower ●December 5, 2002
Mohammed Samdani-

Just a quick glance, so I might be off-base:

-how do you know a5 and a6 are not loaded?
what/where debug are you looking at?

-try 4*nop after mvk 0x700,sum1, to
make sure stw is not in pipeline

-initialize CodStat.HpfPdl also, prior to
branch() call -- make sure you're really
seeing what you think

-to verify: are you sure b14 has base
address for .bss section? you might want
to double-check

hi, thanks

nop are not required in linear assembly, but still i
tried giving nops it did not work

i also initialized the CodStat.HpfPdl, yes and b14 has
the address of bss. but i was not geting the results

hi,

I think it should be:
sth sum,*+b14(_CodStat)
mvk 0x700,sum1
stw sum1,*+b14(_CodStat+2)
LDH *+b14(_CodStat),a5
LDW *+b14(_CodStat+2),a6
Thus you get a5 = sum; a6 = sum1; i.e., HpfZdl = sum and HpfPdl = sum1; does
this you want?

With your code: HpfZd1 = sum; HpfPd1 = sum1 << 16;
