2.7.4. Hardware Breakpoints

NettetHardware breakpoints allow you to set a breakpoint on instructions residing in nonvolatile memory, such as flash memory. The hardware breakpoint mechanism continuously monitors the processor’s current instruction address. If the instruction address matches the hardware breakpoint address, the JTAG debug module takes control of … NettetLoongArch defines hardware watchpoint functions for instruction fetch and load/store operations, after the software configures hardware watchpoints for instruction fetch and load/store operations.

Nettetif it was able to set a hardware watchpoint. Currently, the awatch and rwatch commands can only set hardware watchpoints, because accesses to data that don’t change the value of the watched expression cannot be detected without examining every instruction as it is being executed, and GDB does not do that currently.
