* addr2line: Always parse addresses as hex numbers.Mark Wielaard2015-05-271-1/+1
| | | | | | | | We would sometimes interpret input addresses as decimal or octal. That could be confusing and isn't what binutils addr2line does. Be consistent and always treat input addresses as hex. Signed-off-by: Mark Wielaard <[email protected]>
* libdwfl: Introduce dwfl_module_getsym_info and dwfl_module_addrinfo.Mark Wielaard2013-12-201-0/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some arches like ppc64 use function descriptor values instead of function addresses causing matching of names and addresses to fail when using dwfl_module_getsym or dwfl_module_addrsym. Add ebl hook to resolve any function descriptor values found in non-ET_REL modules. The new function dwfl_module_getsym_info doesn't adjust the symbol value in any way, but returns the adjusted and/or resolved address associated with the symbol separately. The new function dwfl_module_addrinfo resolves against both the address associated with the symbol (which could be the function entry address) value and the adjusted st_value. So that it is easy to resolve and match either function descriptors and/or function entry addresses. Since these new functions also return more information they replace the dwfl_module_getsym_elf and dwfl_module_addrsym_elf functions that never made it into a released elfutils version. addr2line and readelf now use the new functions when looking up functions names. addr2line will now also display the section the address was found in when given -x. Extra testcases were added for both addr2line and the dwflsyms testscase. Signed-off-by: Mark Wielaard <[email protected]>

* Enable automake parallel-tests for make check.Mark Wielaard2013-04-271-10/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The parallel-tests option was introduced in automake 1.11 and is the default since automake 1.13. All tests can now be ran in parallel with make check -j. To enable this all tests are ran in their own temporary directory so they don't stomp on each others input or output files. On my machine (4 cores) make check takes ~20 seconds, but now with make check -j8 takes only ~4 seconds. ChangeLog: * configure.ac (AM_INIT_AUTOMAKE): Request parallel-tests. tests/ChangeLog: * Makefile.am (installed_TESTS_ENVIRONMENT): Export environment, remove wrapper. (TESTS_ENVIRONMENT): Likewise. (installed_LOG_COMPILER): New variable defining wrapper. (LOG_COMPILER): Likewise. * run-*.sh: Fixup location of input and output files. * test-subr.sh: Create test_dir, pushd to execute test in. (trap): Remove test_dir. (testfiles): Use abs_srcdir. (installed_testrun): Match on abs_builddir or abs_top_builddir. (self_test_files): Adjust path. Signed-off-by: Mark Wielaard <[email protected]>
