<!--
|
||||
This file determines the disassembler options sent to the GNU external disassembler.
|
||||
You can see which options are available for all architectures in the objdump man page.
|
||||
Given a version of objdump compiled for a specific architecture, you can see what options
|
||||
are available with "objdump -i -m"
|
||||
|
||||
The options for ARM are:
|
||||
"reg-names-std" (the default)
|
||||
"reg-names-apcs"
|
||||
"reg-names-raw"
|
||||
"reg-names-apcs"
|
||||
"reg-names-special-apcs"
|
||||
"force-thumb" (force thumb disassembly)
|
||||
"no-force-thumb" (force arm disassembly)
|
||||
(see the objdump manpage for the precise details about the different register
|
||||
naming options)
|
||||
|
||||
"optstring" is the string of options, and "display_prefix" is an optional prefix prepended to the
|
||||
external disassembly field. In this file, "A: " is prepended to ARM disassembly, and
|
||||
"T: " is prepended to Thumb disassembly.
|
||||
|
||||
To send multiple options, concatenate them into a CSV list. For example, "no-force-thumb,reg-names-raw"
|
||||
is a valid optstring. You can also have a "global" element whose "optstring" attribute is
|
||||
always sent to the GNU disassembler.
|
||||
|
||||
If there is not a context register defined, the global optstring is sent by itself (see x86-16.gdis for
|
||||
an example). If there is a context register defined, the global optstring is prepended to the
|
||||
optstring determined by a context register value.
|
||||
|
||||
This file must be listed in the .ldefs file for the processor, e.g.
|
||||
<external_name tool="gdis.disassembler.options.file" name="ARM.gdis"/>
|
||||
