Binutils with MCST patches
eae424aef0
This patch series is to allow certain instructions such as the SVE MOVPRFX instruction to apply a constraint/dependency on the instruction at PC+4. This patch starts this off by marking which instructions impose the constraint and which instructions must adhere to the constraint. This is done in a generic way by extending the verifiers. * The constraint F_SCAN indicates that an instruction opens a sequence and imposes a constraint on an instructions following it. The length of the sequence depends on the instruction itself and it handled in the verifier code. * The C_SCAN_MOVPRFX flag is used to indicate which constrain the instruction is checked against. An instruction with both F_SCAN and C_SCAN_MOVPRFX starts a block for the C_SCAN_MOVPRFX instruction, and one with only C_SCAN_MOVPRFX must adhere to a previous block constraint is applicable. The SVE instructions in this list have been marked according to the SVE specification[1].

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.
