* gdb.texinfo (Packets): Mention that packets beginning with

letters are reserved once, at the top, instead of actually listing
|

them all and saying "reserved".

@cindex @code{m} packet
|

|
||||
Read @var{length} bytes of memory starting at address @var{addr}.
|
||||
Neither @value{GDBN} nor the stub assume that sized memory transfers are
|
||||
assumed using word aligned accesses. FIXME: @emph{A word aligned memory
|
||||
transfer mechanism is needed.}
|
||||
Note that @var{addr} may not be aligned to any particular boundary.
|
||||
|
||||
The stub need not use any particular size or alignment when gathering
|
||||
data from memory for the response; even if @var{addr} is word-aligned
|
||||
and @var{length} is a multiple of the word size, the stub is free to
|
||||
use byte accesses, or not. For this reason, this packet may not be
|
||||
suitable for accessing memory-mapped I/O devices.

@var{XX@dots{}} is mem contents. Can be fewer bytes than requested if able
|
||||
to read only part of the data. Neither @value{GDBN} nor the stub assume
|

that sized memory transfers are assumed using word aligned
|

accesses. FIXME: @emph{A word aligned memory transfer mechanism is

@item E@var{NN}

@var{NN} is errno
