[ixp1200] Question about Transactor

[xtan at mail]

I do want to instruct the compiler to generate a specific register
instead of random allocation, or I want the compiler keep the variable
name after the compilation. Coz, I wanna exploit these variables in the
transactor command window:
Ex. dep f0.reg.XXXX_0 = XXXXX

And currently I haven't encountered the problem you mentioned yet. Have
you try the 2.01a patch provided by Intel?

Sincerely yours,
Zhangxi Tan

Do you mean to instruct the compiler to use a specific register for a
variable ?

For example "use @a34 to store fsm_state" ??

No this is not possible.
All allocations are done by the compiler.
This is true even for assembly code thath is
embedded in a microC source file.

You can only instruct the compiler that you want a specific variable
to be placed in a register. Which ever register the compiler wants.

I remember some cases where eventhough I had used the __declspec(gp_reg)
for a variable, the compiler kept on mapping it to the scratch with no
complains/error messages. If you encounter this problem too, then
mosto probably it'll be another compiler bug.
