With gcc-8, we have the following FAILs, which are not there for gcc-7: ... FAIL: gdb.reverse/solib-precsave.exp: reverse-step into solib function one FAIL: gdb.reverse/solib-precsave.exp: reverse-step within solib function one FAIL: gdb.reverse/solib-precsave.exp: reverse-step back to main one FAIL: gdb.reverse/solib-precsave.exp: reverse-step into solib function two FAIL: gdb.reverse/solib-precsave.exp: reverse-step within solib function two FAIL: gdb.reverse/solib-precsave.exp: reverse-step back to main two FAIL: gdb.reverse/solib-precsave.exp: run until end part two FAIL: gdb.reverse/solib-precsave.exp: reverse-next over solib function one FAIL: gdb.reverse/solib-reverse.exp: reverse-step into solib function one FAIL: gdb.reverse/solib-reverse.exp: reverse-step within solib function one FAIL: gdb.reverse/solib-reverse.exp: reverse-step back to main one FAIL: gdb.reverse/solib-reverse.exp: reverse-step into solib function two FAIL: gdb.reverse/solib-reverse.exp: reverse-step within solib function two FAIL: gdb.reverse/solib-reverse.exp: reverse-step back to main two FAIL: gdb.reverse/solib-reverse.exp: run until end part two FAIL: gdb.reverse/solib-reverse.exp: reverse-next over solib function one ... Looking at the first FAIL for gdb.reverse/solib-precsave.exp, we have: ... (gdb) PASS: reverse-next first shr1 reverse-next^M 40 b[0] = 6; b[1] = 9; /* generic statement, end part two */^M (gdb) PASS: reverse-next generic reverse-step^M -shr2 (x=17) at gdb.reverse/shr2.c:23^M -23 }^M -(gdb) PASS: reverse-step into solib function one +38 b[1] = shr2(17); /* middle part two */^M +(gdb) FAIL: reverse-step into solib function one ... There's a difference in line number info for line 38, where for gcc-7 we have: ... Line number Starting address View Stmt 38 0x4005c6 x ... and for gcc-8: ... 38 0x4005c1 x 38 0x4005cb x ... which explains why we don't step directly into "solib function one". Fix this by recognizing the extra "recommended breakpoint location" and issuing an additional reverse-next/step. Tested on x86_64-linux. gdb/testsuite/ChangeLog: 2020-07-21 Tom de Vries <tdevries@suse.de> * gdb.reverse/solib-precsave.exp: Handle additional "recommended breakpoint locations". * gdb.reverse/solib-reverse.exp: Same. |

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.
