GDB PR tdep/8282: MIPS: Wire in `set disassembler-options'
Implement MIPS target support for passing options to the disassembler,
complementing commit 65b48a8140 ("GDB: Add support for the new
set/show disassembler-options commands.").
This includes options that expect an argument, so adjust the generic
code and data structures used so as to handle such options. So as to
give backends syntax flexibility no specific delimiter has been defined
to separate options from their respective arguments, so it has to be
included as the last character of the option name. Completion code
however has not been adjusted and consequently option arguments cannot
be completed at this time.
Also the MIPS target has non-empty defaults for the options, so that ABI
names for the general-purpose registers respect our `set mips abi ...'
setting rather than always being determined from the ELF headers of the
binary file selected. Handle these defaults as implicit options, never
shown to the user and always prepended to the user-specified options, so
that the latters can override the defaults.
The resulting output for the MIPS target is as follows:
(gdb) show disassembler-options
The current disassembler options are ''
The following disassembler options are supported for use with the
'set disassembler-options <option>[,<option>...]' command:
no-aliases Use canonical instruction forms.
msa Recognize MSA instructions.
virt Recognize the virtualization ASE instructions.
xpa Recognize the eXtended Physical Address (XPA) ASE
instructions.
ginv Recognize the Global INValidate (GINV) ASE instructions.
gpr-names=ABI Print GPR names according to specified ABI.
Default: based on binary being disassembled.
fpr-names=ABI Print FPR names according to specified ABI.
Default: numeric.
cp0-names=ARCH Print CP0 register names according to specified architecture.
Default: based on binary being disassembled.
hwr-names=ARCH Print HWR names according to specified architecture.
Default: based on binary being disassembled.
reg-names=ABI Print GPR and FPR names according to specified ABI.
reg-names=ARCH Print CP0 register and HWR names according to specified
architecture.
For the options above, the following values are supported for "ABI":
numeric 32 n32 64
For the options above, the following values are supported for "ARCH":
numeric r3000 r3900 r4000 r4010 vr4100 vr4111 vr4120 r4300 r4400 r4600
r4650 r5000 vr5400 vr5500 r5900 r6000 rm7000 rm9000 r8000 r10000 r12000
r14000 r16000 mips5 mips32 mips32r2 mips32r3 mips32r5 mips32r6 mips64

(gdb)
which corresponds to what `objdump --help' used to print for the MIPS
target, with minor formatting changes, most notably option argument
lists being wrapped, but also the amount of white space separating
options from the respective descriptions. The relevant part the new
code is now also used by `objdump --help', which means these formatting
changes apply to both outputs, except for argument list wrapping, which
is GDB-specific.
This also adds a separating new line between the heading and option
lists where descriptions are provided, hence:
(gdb) set architecture s390:31-bit
(gdb) show disassembler-options
The current disassembler options are ''
The following disassembler options are supported for use with the
'set disassembler-options <option>[,<option>...]' command:
esa Disassemble in ESA architecture mode
zarch Disassemble in z/Architecture mode
insnlength Print unknown instructions according to length from first two bits
(gdb)
but:
(gdb) set architecture powerpc:common
(gdb) show disassembler-options
The current disassembler options are ''
The following disassembler options are supported for use with the
'set disassembler-options <option>[,<option>...]' command:
403, 405, 440, 464, 476, 601, 603, 604, 620, 7400, 7410, 7450, 7455, 750cl,
821, 850, 860, a2, altivec, any, booke, booke32, cell, com, e200z4, e300,
e500, e500mc, e500mc64, e5500, e6500, e500x2, efs, efs2, power4, power5,
power6, power7, power8, power9, ppc, ppc32, 32, ppc64, 64, ppc64bridge,
ppcps, pwr, pwr2, pwr4, pwr5, pwr5x, pwr6, pwr7, pwr8, pwr9, pwrx, raw, spe,
spe2, titan, vle, vsx
(gdb)
Existing affected target backends have been adjusted accordingly.
This has been verified manually with:
(gdb) set architecture arm
(gdb) set architecture powerpc:common
(gdb) set architecture s390:31-bit
to cause no issues with the `show disassembler-options' and `set
disassembler-options' commands. A test case for the MIPS target has
also been provided, covering the default settings with ABI overrides as
well as disassembler option overrides.
