Previously:
fmov d0, #2
would give an error:
Operand 2 should be an integer register
whereas the user probably just forgot to add the ".0" to make:
fmov d0, #2.0
This patch reports an invalid floating point constant unless the
operand is obviously a register.
The FPIMM8 handling is only relevant for SVE. Without it:
fmov z0, z1
would try to parse z1 as an integer immediate zero (the res2 path),
whereas it's more likely that the user forgot the predicate. This is
tested by the final patch.

* config/tc-aarch64.c (parse_aarch64_imm_float): Report a specific
low-severity error for registers.
(parse_operands): Report an invalid floating point constant for
if parsing an FPIMM8 fails, and if no better error has been
recorded.
* testsuite/gas/aarch64/diagnostic.s,
testsuite/gas/aarch64/diagnostic.l: Add tests for integer operands
to FMOV.
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.
