The patch <https://sourceware.org/ml/gdb-patches/2014-03/msg00202.html> fixed dw2-ifort-parameter.exp on powerpc64 by adding some labels to get the start and end address of function func. This should also fix the fail on thumb mode, however, this style is quite specific to gcc, and other compiler, such as clang, may not guarantee the order of global asms and functions. The test fails with clang: $ make check RUNTESTFLAGS='dw2-ifort-parameter.exp CC_FOR_TARGET=clang' (gdb) p/x param^M No symbol "param" in current context.^M (gdb) FAIL: gdb.dwarf2/dw2-ifort-parameter.exp: p/x param With this patch applied, dw2-ifort-parameter.exp still passes for gcc on arm thumb mode and popwerpc64, and it also passes for clang on x86_linux. gdb/testsuite: 2014-11-14 Yao Qi <yao@codesourcery.com> * gdb.dwarf2/dw2-ifort-parameter.c: Remove inline asm. (func): Add label func_label. * gdb.dwarf2/dw2-ifort-parameter.exp (Dwarf::assemble): Replace low_pc and high_pc with MACRO_AT_range. Replace name, low_pc and high_pc with MACRO_AT_func. |

README
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.
