Function Documentation
◆ assume_reg_exist()
|
static |
Some registers are optional (e.g.
"misa"). For such registers it is first assumed they exist (via "assume_reg_exist()"), then the read is attempted (via the usual "riscv_reg_get()") and if the read fails, the register is marked as non-existing (via "riscv_reg_impl_set_exist()").

This function assumes target's DM to be initialized (target is able to access DMs registers, execute program buffer, etc.)
This file describes additional register cache interface available to the RISC-V Debug Specification v0.13+ targets.
