This adds initial compile command support to the RISC-V port. This fixes about 228 testsuite failures on a riscv64-linux machine. We need to get the triplet right which is normally riscv64 or riscv32 instead of the default riscv. Also, we need to get the compiler options right, since we don't accept the default -m64 and -mcmodel=large options, so we need to construct -march and -mabi options which are correct for the target. We currently don't have info about all extensions used by the target, so this may need to be adjusted later. For now, I'm assuming that we have all extensions required by the linux platform spec. gdb/ * riscv-tdep.c (riscv_gcc_target_options): New. (riscv_gnu_triplet_regexp): New. (riscv_gdbarch_init): Call set_gdbarch_gcc_triplet_options and set_gdbarch_gnu_triplet_regexp. Change-Id: I315ce8de7789ddf7bdd3b532f917519464941294
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.
