* libdw: Correct spelling of DW_LANG_PLI in dwarf.h.Mark Wielaard2016-11-101-0/+4
| | | | | | | | | The name used in the standard and other DWARF implementations for Programming Language One, PL/I, is DW_LANG_PLI (not DW_LANG_PL1). Fix usage in dwarf_aggregate_size. Signed-off-by: Mark Wielaard <mjw@redhat.com>

* config: Use --program-prefix=eu- by default.Mark Wielaard2016-03-021-0/+5
| | | | | | | | | | | | We want eu- as default program prefix if none was given by the user. But if the user explicitly provided --program-prefix="" then pretend it wasn't set at all (NONE). This makes sure all tools will be installed as eu-<program>. We want this default since most tools would normally conflict with the GNU binutils variants that have similar names.

* addr2line: Add --pretty-print option to show all information on one line.Mark Wielaard2015-05-271-0/+1
| | | | | | | | | | | | | | | | | | This adds an option --pretty-print to eu-addr2line to show all information on one line and all inlines on a line of their own. This mimics the same option from binutils addr2line, but without the short option variant -p. Since we already use -p to select the process. Example output: eu-addr2line --pretty-print -s -i -f -C -p$(pidof firefox) 0x00007f368c6f8915 mozilla::ReentrantMonitor::Wait(unsigned int) at ReentrantMonitor.h:92 (inlined by) mozilla::ReentrantMonitorAutoEnter::Wait(unsigned int) at ReentrantMonitor.h:190 A couple of tests were added to check the output matches that of binutils addr2line.

* addr2line: Always parse addresses as hex numbers.Mark Wielaard2015-05-271-0/+3
| | | | | | | | 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 <mjw@redhat.com>
* Publish known-dwarf.hPetr Machata2015-03-311-0/+4
| | | | | | | | | | | | | - Make the macro names properly scoped (DWARF_ALL_KNOWN_* and DWARF_ONE_KNOWN_*). - Simplify the calling convention: don't keep track of the comment associated with the enumerator, always use the non-_DESC DWARF_ONE_KNOWN_* callback. - Install known-dwarf.h alongside libdw.h and others.

* Change calling convention of dwarf_getmacros to allow opcode 0xffPetr Machata2014-12-101-2/+0
| | | | | | | | | We now require callers to pass DWARF_GETMACROS_START to start the iteration. 0 is still accepted, but signals to libdw that the iteration request comes from an old-style caller, and that opcode 0xff should be rejected when iterating .debug_macro, to avoid confusion. Signed-off-by: Petr Machata <pmachata@redhat.com>
* Support .debug_macroPetr Machata2014-11-101-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - This code is based on the following proposal: http://www.dwarfstd.org/ShowIssue.php?issue=110722.1 - dwarf_getmacros serves either of .debug_macinfo or .debug_macro transparently, but if the latter uses opcode 0xff, it bails out with an error. The reason is that in .debug_macro, 0xff is a custom code that can mean anything, while in .debug_macinfo there's fixed semantics associated with 0xff. - dwarf_getmacros_off is a new interface used for requesting iteration through transparently included units. - dwarf_macro_getparamcnt and dwarf_macro_param are new interfaces used for requesting number of parameters of an opcode and individual parameters. dwarf_macro_getsrcfiles is a new interface used for requesting a file part of .debug_line unit associated with macro unit that the opcode comes from. - The existing interfaces dwarf_macro_opcode, dwarf_macro_param1 and dwarf_macro_param2 remain operational for old- as well as new-style Dwarf macro sections, if applicable. - dwarf_getsrclines was made into a light wrapper around a worker function that loads line unit given its offset. The worker also caches loaded units in an offset-keyed search tree, so that we don't end up re-reading units even though they were read in a different domain (e.g. a macro unit request can prime cache for later CU lookup). dwarf_macro_getsrcfiles calls the worker function under covers.

* libdw: Add dwarf_peel_type. Use it in dwarf_aggregate_size.Mark Wielaard2014-11-051-0/+5
| | | | | | | | | | | | | | | Add new function dwarf_peel_type. Some type annotations in DWARF are specified by modifier tag type wrappers instead of attributes. For type aliases (typedef) and qualifiers (const, volatile, restrict) tags dwarf_peel_type follows the DW_AT_type attributes till it finds a base, user-defined, reference or pointer type DIE. Use this new function in the backends for return type DIEs (replacing the existing dwarf_peel_type there) and in dwarf_aggregate_size so it can provide the sizes for qualified types too. Add a new version and testcase for the new dwarf_aggregate_size functionality. Signed-off-by: Mark Wielaard <mjw@redhat.com>

* libdw: Add new function dwarf_cu_die.Mark Wielaard2014-08-151-1/+1
| | | | | | | | | | Given a Dwarf_Die or Dwarf_Attribute it is often convenient to get at the CU DIE and the CU header information. There is dwarf_diecu but that doesn't provide all information from the header and it doesn't work for attributes. Add a new dwarf_cu_die function that provides all information given a Dwarf_CU, which both Dwarf_Die and Dwarf_Attribute reference. Signed-off-by: Mark Wielaard <mjw@redhat.com>
* libdw: Add new function dwarf_cu_getdwarf.Mark Wielaard2014-08-151-0/+2
| | | | | | | | | | | In both systemtap and libabigail there is a need to get the actual Dwarf underlying an Dwarf_Die or Dwarf_Attribute. Following a DIE reference might end up in an alternate Dwarf since the addition of DWZ multifile forms. Both Dwarf_Die and Dwarf_Attribute already contain a Dwarf_CU handle. Add a function dwarf_cu_getdwarf to retrieve the underlying Dwarf using the Dwarf_CU. Signed-off-by: Mark Wielaard <mjw@redhat.com>
* unstrip: Add --force to force combining files when ELF headers don't match.Mark Wielaard2014-05-271-0/+5
| | | | | | | | | | | | | | Older versions of GNU binutils strip would drop some ELF header flags. Causing the main ELF file and the separate .debug file to have mismatched ELF header fields. Unfortunately some distros are still shipping such files. eu-unstrip doesn't want to recombine such files. Add a more explicit explanation which fields don't match and provide a --force, -F flag to force combining such files anyway (producing a warning). https://bugzilla.redhat.com/show_bug.cgi?id=698005 https://bugzilla.redhat.com/show_bug.cgi?id=806474 Signed-off-by: Mark Wielaard <mjw@redhat.com>

| | | | | | | | New public header elfutils/libdwelf.h for low-level DWARF/ELF helper functions. The new function dwelf_elf_gnu_debuglink returns the name and crc as found in the .gnu_debuglink section of an ELF file. Signed-off-by: Mark Wielaard <mjw@redhat.com>
* stack: Add -i, --inlines. Show inlined call frames using DWARF debuginfo.Mark Wielaard2014-01-271-0/+1
| | | | | | | | | | Using dwarf_getscopes_die we can get all scopes that make up the current subprogram representing an address. Using the call_file/line/column attributes we can also show the source locations of these "inlined" calls. Includes a test that shows that when DWARF debuginfo is available all inlined function call frames and their source location can be shown. Signed-off-by: Mark Wielaard <mjw@redhat.com>

* libdwfl: Add dwfl_getthread_frames.Mark Wielaard2013-12-231-1/+4
| | | | | | | | | | | | | | | | dwfl_getthread_frames is a convenience function for when the user is only interested in one specific thread id of a process. It can be implemented by a simple wrapper function that removes an extra callback layer just to filter on thread id. But it also provides an optimized path to getting access to just one particular Dwfl_Thread of the Dwfl process by providing and (optional) new callback for the state provider. The pid_thread_callbacks now provide an (optional) pid_getthread that doesn't need to travers all threads anymore. Which is implemented for the linux-pid-attach provider. stack now uses this to implement a new '-1' option that shows just one specific thread of a process.

* libdwfl: Introduce dwfl_module_getsym_info and dwfl_module_addrinfo.Mark Wielaard2013-12-201-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <mjw@redhat.com>

Allows users to first search through all global symbols before searching the local symbols in the table like dwfl_module_addrsym and dwfl_module_addrsym_info do as optimization.
