|
Tracing can also be enabled and disabled from within a target program
|
|
using the `l.nop 8' and `l.nop 9' opcodes to enable and disable tracing
|
|
respectively.
|
|
|
|
By default tracing will show the virtual address of each instruction
|
|
traced. This may be controlled by two options, `--trace-physical' to
|
|
show the physical address and/or `--trace-virtual' to show the virtual
|
|
address. If neither is specified, the virtual address is shown.
|
|
|
|
Note: Either or both flags may be specified without `--trace', to
|
|
indicate how addresses should be shown if subsequently enabled by a
|
|
`SIGUSER1' signal or `l.nop 8' opcode.
