A debug packet whose contents are <data>
|
|
|
|
|
is encapsulated for transmission in the form:
|
|
|
|
|
|
|
|
|
|
$ <data> # CSUM1 CSUM2
|
|
|
|
|
|
|
|
|
|
<data> must be ASCII alphanumeric and cannot include characters
|
1994-03-30 05:50:23 +02:00
|
|
|
|
'$' or '#'. If <data> starts with two characters followed by
|
|
|
|
|
':', then the existing stubs interpret this as a sequence number.
|
1993-06-25 21:44:18 +02:00
|
|
|
|
|
|
|
|
|
CSUM1 and CSUM2 are ascii hex representation of an 8-bit
|
|
|
|
|
checksum of <data>, the most significant nibble is sent first.
|
|
|
|
|
the hex digits 0-9,a-f are used.
|
|
|
|
|
|
|
|
|
|
Receiver responds with:
|
|
|
|
|

+ - if CSUM is correct and ready for next packet
|
|
|
|
|
- - if CSUM is incorrect
|
|
|
|
|
|
|
|
|
|
<data> is as follows:
|
1991-03-28 17:26:26 +01:00

All values are encoded in ascii hex digits.

* Makefile.in (TAGS): Use variables directly, rather than using
find, to locate TM_FILE, XM_FILE, and NAT_FILE. This is faster
and means that these filenames no longer need be unique across all
the config/* directories.
* configure.in: Put the config/*/ into TM_FILE, etc.
* m68k-stub.c (computeSignal): Return SIGFPE, not SIGURG, for chk
and trapv exceptions.
* target.h (struct section_table), objfiles.h (struct obj_section):
Change name of field sec_ptr to the_bfd_section. More mnemonic
and avoids the (sort of, for the ptx compiler) name clash with
the name of the typedef.
* exec.c, xcoffexec.c, sparc-tdep.c, rs6000-nat.c, osfsolib.c,
solib.c, irix5-nat.c, objfiles.c, remote.c: Change users.
* utils.c: Include readline.h.
* Makefile.in (utils.o): Add dependency.
* remote.c (getpkt): Add support for run-length encoding.

* Makefile.in (TAGS): Use variables directly, rather than using
find, to locate TM_FILE, XM_FILE, and NAT_FILE. This is faster
and means that these filenames no longer need be unique across all
the config/* directories.
* configure.in: Put the config/*/ into TM_FILE, etc.
* m68k-stub.c (computeSignal): Return SIGFPE, not SIGURG, for chk
and trapv exceptions.
* target.h (struct section_table), objfiles.h (struct obj_section):
Change name of field sec_ptr to the_bfd_section. More mnemonic
and avoids the (sort of, for the ptx compiler) name clash with
the name of the typedef.
* exec.c, xcoffexec.c, sparc-tdep.c, rs6000-nat.c, osfsolib.c,
solib.c, irix5-nat.c, objfiles.c, remote.c: Change users.
* utils.c: Include readline.h.
* Makefile.in (utils.o): Add dependency.
* remote.c (getpkt): Add support for run-length encoding.

* Makefile.in (TAGS): Use variables directly, rather than using
find, to locate TM_FILE, XM_FILE, and NAT_FILE. This is faster
and means that these filenames no longer need be unique across all
the config/* directories.
* configure.in: Put the config/*/ into TM_FILE, etc.
* m68k-stub.c (computeSignal): Return SIGFPE, not SIGURG, for chk
and trapv exceptions.
* target.h (struct section_table), objfiles.h (struct obj_section):
Change name of field sec_ptr to the_bfd_section. More mnemonic
and avoids the (sort of, for the ptx compiler) name clash with
the name of the typedef.
* exec.c, xcoffexec.c, sparc-tdep.c, rs6000-nat.c, osfsolib.c,
solib.c, irix5-nat.c, objfiles.c, remote.c: Change users.
* utils.c: Include readline.h.
* Makefile.in (utils.o): Add dependency.
* remote.c (getpkt): Add support for run-length encoding.
