G.5.3 ARM Features
------------------
The 'org.gnu.gdb.arm.core' feature is required for non-M-profile ARM
targets. It should contain registers 'r0' through 'r13', 'sp', 'lr',
'pc', and 'cpsr'.
For M-profile targets (e.g. Cortex-M3), the 'org.gnu.gdb.arm.core'
feature is replaced by 'org.gnu.gdb.arm.m-profile'. It should contain
registers 'r0' through 'r13', 'sp', 'lr', 'pc', and 'xpsr'.
The 'org.gnu.gdb.arm.fpa' feature is optional. If present, it should
contain registers 'f0' through 'f7' and 'fps'.
The 'org.gnu.gdb.xscale.iwmmxt' feature is optional. If present, it
should contain at least registers 'wR0' through 'wR15' and 'wCGR0'
through 'wCGR3'. The 'wCID', 'wCon', 'wCSSF', and 'wCASF' registers are
optional.
The 'org.gnu.gdb.arm.vfp' feature is optional. If present, it should
contain at least registers 'd0' through 'd15'. If they are present,
'd16' through 'd31' should also be included. GDB will synthesize the
single-precision registers from halves of the double-precision
registers.
The 'org.gnu.gdb.arm.neon' feature is optional. It does not need to
contain registers; it instructs GDB to display the VFP double-precision
registers as vectors and to synthesize the quad-precision registers from
pairs of double-precision registers. If this feature is present,
'org.gnu.gdb.arm.vfp' must also be present and include 32
double-precision registers.
