This gdbserver implementation supports ARC ABI v3 and v4 (older ARC ABI versions are not supported by other modern GNU tools or Linux itself). Gdbserver supports inspection of ARC HS registers R30, R58 and R59 - feature that has been added to Linux 4.12. Whether gdbserver build will actually support this feature depends on the version of Linux headers used to build the server. v2 [1]: - Use "this->read_memory ()" instead of "the_target->read_memory ()". - Remove the unnecessary "arch-arc.o:" target from the "Makefile.in". - Got rid of "ntohs()" function and added lots of comments about endianness. - Clarify why "pc" value is read from and saved to different fields in user regs struct. - In function "is_reg_name_available_p()", use a range-based iterator to loop over the registers. - Removed mentioning of issue number that was not related to sourceware. - A few typo's fixed.

README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
