Display Breakpoints
Format of the Code Breakpoint Display
Debug displays TNS and native code breakpoints in this form:
TNS code breakpoint:
Native code breakpoint:
[@ | >] code-segment, addr-16 INS: instr SEG:memory-seg
[PIN: { <pin-num> | ALL }
]
INS: mnemonic-instr
[ condition ]
[ trace ]
[ command-string ]
[^--] N: addr-32 INS: instr-32
INS: mnemonic-instr-32
[ condition ]
[ trace ]
[ command-string ]
> (greater-than sign) denotes a memory-exact point, for
accelerated programs only.
@ (commercial at sign) denotes a register-exact point, for
accelerated programs only.
code-segment defines the TNS code segment where the breakpoint is set.
Segments are:
UC.segment-num ! in user code space
UL.segment-num ! in user library space
SC.segment-num ! in system code space (privileged only)
SL.segment-num ! in system library space (privileged only)
Characters appearing in the display before UC, UL, SC, or SL
indicate that the breakpoint is set on corresponding TNS and
RISC instructions as follows:
addr-16 is the 16-bit word address where the breakpoint is set. This
address is within the specified code segment.
instr is the octal value of the instruction at the address defined by
code-segment, addr-16. This value is the value of the
instruction at the time the breakpoint was set. While the
breakpoint is set, the content of code-segment, addr-16 is a
BPT (TNS) instruction (000451).
SEG is the segment in memory where the breakpoint is set.
memory-seg the memory segment.
