[ Using $build for /home/vries/gdb_versions/devel/build to make things a bit more readable. ] When using make check// to run test-case gdb.dwarf2/fission-base.exp: ... ( cd $build/gdb; make check//unix RUNTESTFLAGS="fission-base.exp" ) ... we run into: ... (gdb) file \ $build/gdb/testsuite.unix/outputs/gdb.dwarf2/fission-base/fission-base^M Reading symbols from \ $build/gdb/testsuite.unix/outputs/gdb.dwarf2/fission-base/fission-base...^M warning: Could not find DWO CU \ $build/gdb/testsuite.1/outputs/gdb.dwarf2/fission-base/fission-base.dwo \ (0x807060504030201) referenced by CU at offset 0xc7 [in module \ $build/gdb/testsuite.unix/outputs/gdb.dwarf2/fission-base/fission-base]^M ... The problem is that the executable refers to the dwo file using path name $build/gdb/testsuite.1/outputs/gdb.dwarf2/fission-base/fission-base.dwo, while the actual dwo file is at $build/gdb/testsuite.unix/outputs/gdb.dwarf2/fission-base/fission-base.dwo. This is caused by this trick in fission-base.S: ... #define XSTR(s) STR(s) #define STR(s) #s ... .asciz XSTR(DWO) # DW_AT_GNU_dwo_name ... and: ... $ echo | gcc -E -dD - | grep "define unix" ... I used this trick to avoid doing additional_flags=-DDWO=\"$dwo\", since I was concerned that there could be quoting issues. However, I've found other uses of this pattern, f.i. in gdb/testsuite/gdb.base/corefile-buildid.exp: ... additional_flags=-DSHLIB_NAME=\"$dlopen_lib\"] ... So, fix this by: - using additional_flags=-DDWO=\"$dwo\" and - using plain DWO instead of XSTR(DWO) Likewise in other gdb.dwarf2/fission*.exp test-cases. Tested on x86_64-linux, using make check//unix. gdb/testsuite/ChangeLog: 2021-09-01 Tom de Vries <tdevries@suse.de> PR testsuite/28298 * gdb.dwarf2/fission-base.S: Use DWO instead of XSTR(DWO). * gdb.dwarf2/fission-loclists-pie.S: Same. * gdb.dwarf2/fission-loclists.S: Same. * gdb.dwarf2/fission-reread.S: Same. * gdb.dwarf2/fission-base.exp: Use additional_flags=-DDWO=\"$dwo\". * gdb.dwarf2/fission-loclists-pie.exp: Same. * gdb.dwarf2/fission-loclists.exp: Same. * gdb.dwarf2/fission-reread.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.
