This patch cleans up the decoding functions using booleans when they can decode two instructions. The boolean argument is used to know which of the two instructions was decoded. The instructions affected are BR/BLR, B/BL, CBZ/CBNZ and TBZ/TBNZ. These arguments would be named after a named bit in the instruction encoding, this patch renames them to 'is_XXX'. Furthermore, the 'unsigned' type would be used to describe a boolean while aarch64_decode_cb would use 'int' (see the 'is64' argument). This patch makes all booleans be 'int' and decoded bitfields be 'unsigned'. gdb/ChangeLog: * aarch64-tdep.c (decode_b): Rename link argument to is_bl. Change its type to int *. (decode_br): Rename link argument to is_blr. Change its type to int *. (decode_cb): Rename op argument to is_cbnz. Change its type to int *. (decode_tb): Rename op argument to is_tbnz. Change its type to int *. Set is_tbnz to either 1 or 0. (aarch64_analyze_prologue): Change type of is_link to int. Add new variables is_cbnz and is_tbnz. Adjust call to aarch64_decode_cb and aarch64_decode_tb.
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.
