This commit is actually an update to make the parser in gdb/stap-probe.c be aware of all the possible prefixes that a probe argument can have. According to the section "Argument Format" in: <https://sourceware.org/systemtap/wiki/UserSpaceProbeImplementation> The bitness of the arguments can be 8, 16, 32 or 64 bits, signed or unsigned. Currently GDB recognizes only 32 and 64-bit arguments. This commit extends this. It also provides a testcase, only for x86_64 systems. gdb/ 2014-05-02 Sergio Durigan Junior <sergiodj@redhat.com> * stap-probe.c (enum stap_arg_bitness): New enums to represent 8 and 16-bit signed and unsigned arguments. Update comment. (stap_parse_probe_arguments): Extend code to handle such arguments. Use warning instead of complaint to notify about unrecognized bitness. gdb/testsuite/ 2014-05-02 Sergio Durigan Junior <sergiodj@redhat.com> * gdb.arch/amd64-stap-optional-prefix.S (main): Add several probes to test for bitness recognition. * gdb.arch/amd64-stap-optional-prefix.exp (test_probe_value_without_reg): New procedure. Add code to test for different kinds of bitness.
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.
