ARMulator Reference

RDICycles

Models that have declared a statistics counter by trapping

RDIRequestCyclesDesc

must also respond to

RDICycles

by calling

ARMul_AddCounterValue()

(see General purpose functions on page 4-41)

for each counter in turn, in the same order as they were declared.

The above RDI info calls have already been dealt with by ARMulator, and are passed

for information only, or so that models can add information to the reply. Models must

always respond to these messages with

RDIError_UnimplementedMessage

, so that the

message is passed on even if the model has responded.

Install the handler using:

int ARMulif_InstallUnkRDIInfoHandler(RDI_ModuleDesc *mdesc,

RDI_InfoProc *func, void *handle)

Remove the handler using:

int ARMulif_RemoveUnkRDIInfoHandler(RDI_ModuleDesc *mdesc,

RDI_InfoProc *func, void *handle)

Example

The

semihost.c

model supplied with ARMulator uses the

UnkRDIInfoUpcall()

to interact

with the debugger:

RDIErrorP

returns errors raised by the program running under ARMulator to

the debugger.

RDISet_Cmdline

finds the command line set for the program by the debugger.

RDIVector_Catch

intercepts the hardware vectors.
