I see two fails in async.exp on arm-none-eabi target: nexti&^M (gdb) 0x000001ba 14 x = 5; x = 5;^M completed.^M FAIL: gdb.base/async.exp: nexti& finish&^M Run till exit from #0 0x000001ba in foo () at /scratch/yqi/arm-none-eabi-lite/src/gdb-trunk/gdb/testsuite/gdb.base/async.c:14^M (gdb) 0x000001e6 in main () at /scratch/yqi/arm-none-eabi-lite/src/gdb-trunk/gdb/testsuite/gdb.base/async.c:32^M 32 y = foo ();^M Value returned is $1 = 8^M completed.^M FAIL: gdb.base/async.exp: finish& The corresponding test is "test_background "nexti&" "" ".*y = 3.*"", and it assumes that GDB "nexti" into the next source line. It is wrong on arm. After "nexti", it still stops at the same source line, and it fails. When gdb does "finish", if the PC is in the middle of a source line, the PC address is printed too. See stack.c:print_frame, if (opts.addressprint) if (!sal.symtab || frame_show_address (frame, sal) || print_what == LOC_AND_ADDRESS) { annotate_frame_address (); if (pc_p) ui_out_field_core_addr (uiout, "addr", gdbarch, pc); else ui_out_field_string (uiout, "addr", "<unavailable>"); annotate_frame_address_end (); ui_out_text (uiout, " in "); } frame_show_address checks whether PC is the middle of a source line. Since after "nexti", the inferior stops at the middle of a source line, when we do "finish" the PC address is displayed. In sum, GDB works well, but test case needs update. This patch is to add a statement at the same line to make sure "nexti" doesn't go to the new line, match the next instruction address in the output and match the hex address the output of "finish". gdb/testsuite: 2014-06-06 Yao Qi <yao@codesourcery.com> * gdb.base/async.c (foo): Add one statement. * gdb.base/async.exp: Get the next instruction address and match the output of "nexti" by instruction address. Match the hex address in the output of "finish". |

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.
