21.6 gdb/mi Data manipulation
This section describ es the gdb/mi commands that manipulate data: examine memory
and registers, evaluate expressions, etc.
The -data-disassemble command
Synopsis
-data-disassemble
[ -s start-addr -e end-addr ]
| [ -f filename -l linenum [ -n lines ] ]
-- mode
Where:
‘start-addr ’
is the beginning address (or $pc)
‘end-addr ’
is the end address
‘filename ’
is the name of the file to disassemble
‘linenum ’ is the line number to disassemble around
‘lines ’ is the the number of disassembly lines to be produced. If it is -1, the whole
function will be disassembled, in case no end-addr is spec ified. If end-addr is
specified as a non-zero value, and lines is lower than the number of disassembly
lines b etween start-addr and end-addr, only lines lines are displayed; if lines
is higher than the number of lines between start-addr and end-addr, only the
lines up to end-addr are displayed.
‘mode ’ is either 0 (meaning only disassembly) or 1 (meaning mixed source and disas-
sembly).
