Since we have no insn suffix and it's also not realistic to infer immediate size from the size of other (typically register) operands (like optimize_imm() does), and since we also don't have a template telling us permitted size(s), a new syntax construct is introduced to allow size (and signedness) specification. In the absence of such, the size is inferred from significant bits (which obviously may yield inconsistent results at least for effectively negative values, depending on whether BFD64 is enabled), and only if supplied expressions can be evaluated at parsing time. Being explicit is generally recommended to users. Size specification is permitted at bit granularity, but of course the eventually emitted immediate values will be padded up to 8-, 16-, 32-, or 64-bit fields.
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.
