Hi, I am seeing the fail below on aarch64-linux with gcc 4.9.2, break main Breakpoint 1 at 0x4006e8: file binutils-gdb/gdb/testsuite/gdb.base/annota1.c, line 14.^M (gdb) FAIL: gdb.base/annota1.exp: breakpoint main the test expects the breakpoint is set on line 15. Let us look at the main function, 12 int 13 main (void) 14 { 15 int my_array[3] = { 1, 2, 3 }; /* break main */ 16 17 value = 7; 18 19 #ifdef SIGUSR1 20 signal (SIGUSR1, handle_USR1); 21 #endif (gdb) disassemble main Dump of assembler code for function main: 0x00000000004006e0 <+0>: stp x29, x30, [sp,#-48]! 0x00000000004006e4 <+4>: mov x29, sp 0x00000000004006e8 <+8>: adrp x0, 0x411000 <signal@got.plt> 0x00000000004006ec <+12>: add x0, x0, #0x40 the breakpoint is set on the right address after skipping prologue, but 0x00000000004006e8 is mapped to the line 14, as shown below, (gdb) maintenance info line-table objfile: /home/yao.qi/source/build-aarch64/gdb/testsuite/outputs/gdb.base/annota1/annota1 ((struct objfile *) 0x2b0e1850) compunit_symtab: ((struct compunit_symtab *) 0x2b0ded50) symtab: /home/yao.qi/source/binutils-gdb/gdb/testsuite/gdb.base/annota1.c ((struct symtab *) 0x2b0dedd0) linetable: ((struct linetable *) 0x2b12c8b0): INDEX LINE ADDRESS 0 7 0x00000000004006d0 1 8 0x00000000004006d8 2 14 0x00000000004006e0 3 14 0x00000000004006e8 4 15 0x00000000004006fc so GDB does nothing wrong. Program hits breakpoint on either line 14 or line 15 is right to me. With anther gcc (4.9.3), the line-table looks correct, and no test fail. Instead of setting breakpoint on main and assuming the line is what we get from the source, we can set breakpoint on that line. On the other hand, the test prints the values of the array and check, so we need to set breakpoint on the line setting the values of array and "next", rather than setting the breakpoint on main. gdb/testsuite: 2016-04-22 Yao Qi <yao.qi@linaro.org> * gdb.base/annota1.exp: Set breakpoint on line $main_line. * gdb.base/annota3.exp: Likewise. |

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.
