* libdw: Try both the relative and absolute paths when finding a .dwo file.Mark Wielaard2018-06-014-47/+92
| | | | | | | | We would give up if one of them failed. With this fixed a self-test with make check succeeds when building elfutils itself with CFLAGS set to "-gdwarf-4 -gdwarf-split -O2". Signed-off-by: Mark Wielaard <[email protected]>
* readelf: Fix .debug_types printing with implicit section_info.Mark Wielaard2018-06-015-6/+149
| | | | | | | | | | | | | Commit 314e9d7d "readelf: Handle .debug_info first if any other debug section needs it" disabled section_info printing if it was already handled. But section_types was an alias for section_info. So unless section_info was explicitly printed, .debug_types wasn't. Make section_types its own thing to print .debug_types and make section_info imply section_types. Add a testcase to make sure .debug_types is now printed.

* readelf: Deal with combined normal and split dwarf DebugFission .debug_loc.Mark Wielaard2018-06-018-3/+359
| | | | | | | | | | | | | Normal and split dwarf from GNU DebugFission look the same, but should be treated competely separtely. When having a file with both skeletons and real compile units only note the secoffsets into the real .debug_loc in readelf. Otherwise or known_locslistptr will get confused. Add a testfile that combines an normal -gdwarf-4 object with a -gsplit-dwarf object. libdw already got this right, but add a run-varlocs.sh test to make sure.

* tests: Split self_test_files into an exe, lib and obj list.Mark Wielaard2018-06-014-6/+53
| | | | | | | | | | Introduce testrun_on_self_exe and testrun_on_self_lib. Some tests cannot handle (unrelocated) ET_REL object files. run-get-units-split.sh and run-unit-info.sh only handle executables and shared libraries. This allows running the whole testsuite on an elfutils build done with CFLAGS="-gdwarf-4 -gsplit-dwarf -O2". Signed-off-by: Mark Wielaard <[email protected]>

* libdw: Handle split Dwarf Dies in dwarf_die_addr_die.Mark Wielaard2018-05-3110-2/+133
| | | | | | | | | | | | | | | | | | | dwarf_die_addr_die can be used to turn an Dwarf_Die addr back into a full Dwarf_Die, just given the original Dwarf debug handle. This now also works for Dwarf_Dies which originated from a split Dwarf. Whenever a split Dwarf_CU is found the Dwarf it originated from is registered with the Dwarf that the skeleton Dwarf_CU came from. All registered split Dwarfs are then searched by dwarf_die_addr_die if the addr didn't match the main Dwarf or the alt Dwarf. One limitation in this implementation is that only DIEs that come from the main .debug_info in the .dwo are supported. Theoretically there could also be DIEs in an .debug_type or from other/multiple (comdat) sections. New tests are added for dwarf-4, dwarf-5, split-dwarf-4, split-dwarf-5 and version 4 and 5 dwo files. Signed-off-by: Mark Wielaard <[email protected]>
* readelf, libdw: Add GNU DebugFission .debug_loc support.Mark Wielaard2018-05-318-7/+382
| | | | | | | | | | GNU DebugFission .debug_loc location lists uses the .debug_loc section in the split dwarf .dwo file. The encoding is a mix of old style DWARF .debug_loc and new style .debug_loclists. Add two testcases for the readelf and libdw decoders. Signed-off-by: Mark Wielaard <[email protected]>
* readelf: Fix regression with multiple files and implicit debug_info reading.Mark Wielaard2018-05-314-2/+60
| | | | | | | | | | | | | | Commit 314e9d7d "readelf: Handle .debug_info first if any other debug section needs it" introduced a regression when handling multiple files. The implicit and explicit printing of debuginfo weren't reset and so the second file would not show (or scan) the .debug_info section when needed. Fix by resetting the implicit and explicit section printing flags. Add a testcase that prints the .debug_loc section for two files and check that the CUs are resolved.

* libdw: Fix memory corruption in libdw_find_split_unit.Mark Wielaard2018-05-307-9/+56
| | | | | | | | | | | Found by valgrind when trying to match a split unit from a .dwo file that doesn't contain the split unit (as first) match. We would close the split Dwarf too early, before we had inspected all units in it. Add a testcase that simulates this. Which failed (at least under valgrind as run by make distcheck) before the fix.

* readelf: Handle .debug_str_offsets.Mark Wielaard2018-05-305-3/+440
| | | | | | | | | | | | | | | | The .debug_str_offsets tables are indirect string offsets into the .debug_str section. For DWARF5 they can be in both the main, skeleton and split dwarf (.dwo) files. For DWARF4 with the GNU DebugFission extension the tables will not have an header and they will only be in the split DWARF (.dwo) file, never in the main (skeleton) file. For DWARF5 the (non-split) unit DIE will have a DW_AT_str_offsets_base attribute pointing at the actual index (after the header). The split unit will never have this attribute (and use the table at offset zero). Signed-off-by: Mark Wielaard <[email protected]>
* readelf handle .debug_addr section.Mark Wielaard2018-05-306-4/+431
| | | | | | | | | | Add debug-dump=addr which will show the .debug_addr section tables. The only tricky bit is the fact that GNU DebugFission, a DWARF4 extension, didn't produce unit table headers. So if we see a mixed DWARF4/5 .debug_addr table we have to reconstruct the table length from the CU DIE DW_AT_[GNU_]_addr_base offsets. Signed-off-by: Mark Wielaard <[email protected]>
* libdw: Handle .debug_loclists in dwarf_getlocation.Mark Wielaard2018-05-3013-25/+539
| | | | | | | | | | | | | Handle all new DW_LLE opcodes in .debug_loclists in dwarf_getlocation. __libdw_read_begin_end_pair_inc now also handles a default location (which is simply the range [0,-1]). Since expression blocks can now also come from the .debug_loclists section add a new fake_loclists_cu necessary for checking bounds while parsing expression blocks. Adapt varlocs test to handle debug-only files. Test testfileranges5.debug and testfilesplitranges5.debug with it. Signed-off-by: Mark Wielaard <[email protected]>
* readelf: Handle .debug_loclists.Mark Wielaard2018-05-2911-22/+1191
| | | | | | | | | The new DWARF5 .debug_loclists sections are like .debug_rnglists, but plus locations. For Split Dwarf GCC generates the .debug_loclists fully in the split .dwo file. Any references to addresses need to be resolved through the skeleton .debug_addr section. Signed-off-by: Mark Wielaard <[email protected]>
* libdwfl: Allow partial relocations also for debug files.Mark Wielaard2018-05-292-1/+6
| | | | | | | | | | | | | | __libdwfl_relocate is called for get_dwarf and get_elf. We allow not all relocations to be resolved for Elf files, but required all relocations (in the debug sections) to be fully resoled in Dwarf files. This used to mostly work out with .o ET_REL files when the main Elf was gotten before the Dwarf. But with .dwo files, we (readelf) might open the .o file just for the (skeleton) Dwarf. In this case it could happen not all relocations in the debug sections could be resolved (.debug_info and .debug_addr might contain referenes to undefined symbols). So allow partial relocations also for debug files. Signed-off-by: Mark Wielaard <[email protected]>
* readelf: Find skeleton units when inspecting split .dwo (--dwarf-skeleton).Mark Wielaard2018-05-285-43/+288
| | | | | | | | | | | | | | | | | | | To get the right context (especially addresses) when looking at a .dwo file we really need the skeleton file. If we can find it (simply replace .dwo with .o) then use that to get to the split DWARF units so that libdw sets up all relevant information to resolve. Also adds a --dwarf-skeleton option so the user can explicitly give a skeleton file to use (for example when all .o files are linked and removed already). Unfortunately this might not work if libdw cannot get from the skeleton file to the .dwo file (because they have been moved around). In that case eu-readelf "cheats", it will link up the libdw datastructures so that the skeleton and split DWARF units are setup correctly anyway. This does introduce a problem when trying to cleanup the Dwarf handle ownership graph. So we will deliberately leak memory by not closing the underlying Dwfl in that case.

| | | | | | | | | | dwarf_highpc can use any address FORM, not just DW_FORM_addr. Just try whether the address can be resolved as address. Always set error when attribute couldn't be found or resolved. When calculating the base address for a CU don't try to second guess the error code, just treat an error the same as the attribute not being there. Signed-off-by: Mark Wielaard <[email protected]>
* libdw: Support DW_OP_addrx/constx and split DWARF addrx/constx support.Mark Wielaard2018-05-2519-41/+523
| | | | | | | | | | | | | | | | | | | DW_OP_addrx/constx and GNU DebugFission DW_OP_GNU_addr/const_index take as argument an index into the .debug_addr section for the associated CU. This index gets resolved through dwarf_getlocation_attr. A new fake addr CU is created per Dwarf for use with this new attribute. For split DWARF files, the IDX_debug_addr gets replaced with the skeleton section and the addr base is resolved immediately when constructing the split DWARF CU. Move __libdw_cu_addr_base to libdwP.h to share with eu-readelf. Also make it possible to resolve addrx[1234]/GNU_addr_index also as constant indexes to (also) show when displaying these attributes in eu-readelf. A new varlocs tests is added to test the resolving for both the DWARF4 and DWARF5 DW_OP variants. And now that addrx forms are resolved in split DWARF files add the new DIEs with "single ranges" (those DIEs that have a lowpc/highpc attribute pair) to run-all-dwarf-ranges.sh.

* libdw: Add new dwarf_cu_info function.Mark Wielaard2018-05-249-5/+542
| | | | | | | | | | | | | This allows getting a (split) subdie lazily, only when needed. All arguments to dwarf_get_units are optional. When not given then unit DIE and sub DIE are not looked up. This new function allows them to be looked up when not immediately retrieved with dwarf_get_units, or for a Dwarf_CU gotten through some other way.

* libdw: Initialize ranges_base, add invalid DWARF test and fix expected output.Mark Wielaard2018-05-246-4/+29
| | | | | | | | We never initialized the CU ranges_base, which meant we didn't actually calculate it correctly. This caused bad ranges on some DIEs. The expected output in the testcase was wrong. We also crashed on invalid dwarf. Signed-off-by: Mark Wielaard <[email protected]>
* libdw: Handle GNU DebugFission split ranges.Mark Wielaard2018-05-2313-26/+281
| | | | | | | | | | | | | | | | | GNU DebugFission split dwarf handles DW_FORM_sec_offset specially for attributes that point to ranges. The .debug_ranges section is not in the .dwo file, but in the main/skeleton object file. The sec_offset is not relocated (in the ELF file), but is an offset against the skeleton DIE DW_AT_GNU_ranges_base attribute. dwarf_formudata is changed so it still looks like a normal offset ptr into the .debug_ranges section. dwarf_ranges is adapted to look for the .debug_ranges in the main object file. dwarf_highpc and dwarf_lowpc now handle the highpc and lowpc attributes being inherited for the split unit DIE from the skeleton. A new testcase is added to iterate over all ranges in a split GNU DebugFission file. Signed-off-by: Mark Wielaard <[email protected]>
* libdw: Handle split dwarf debuglines.Mark Wielaard2018-05-226-9/+148
| | | | | | | | | | | Split DWARF .dwo files do contain a .debug_line section, but only with the file table, there is no actual line program. Also split DWARF CU DIEs don't have a DW_AT_stmt_list attribute. To get at the file (and dir) table for a split unit DIE take just the files from the .debug_line section (at offset zero). To get the full line table use the skeleton DIE (which does have a DW_AT_stmt_list). Signed-off-by: Mark Wielaard <[email protected]>
* libdw: Cache ELF directory early. Explicitly set it in dwfl.Mark Wielaard2018-05-2011-45/+112
| | | | | | | | | | | The logic that finds alt files and dwo files relies on having an open file descriptor. But after all needed ELF data has been read the underlying Elf file descriptor can be closed. libdwfl in particular closes file descriptor fairly aggressively. So capture the directory early on. And make dwfl set it if it has recorded it. Which it will do now before closing a file descriptor for the main Dwfl_Module file. Signed-off-by: Mark Wielaard <[email protected]>

* libdw: dwarf_get_units find split units from .dwo.Mark Wielaard2018-05-1918-9/+374
| | | | | | | | | | | | For a skeleton DIE dwarf_get_units should provide the split DIE as subdie. This implements that by trying to find the (named) .dwo file and finding the matching CU in it. The .dwo file is search relative to the current DWARF or using the comp_dir of the skeleton DIE. Also fixes a small issue with str_offsets_base_off which is tested in the new testcase (by getting the name of the split CU DIE). Signed-off-by: Mark Wielaard <[email protected]>

* libdw: Fix crashing on illegal/zero Dwarf_Die.Mark Wielaard2018-05-157-5/+167
| | | | | | | | | | | In some cases we create an illegal Dwarf_Die by clearing all fields. The idea is that dwarf_tag () on such a Dwarf_Die will return DW_TAG_invalid, to indicate that the Dwarf_Die is unusable (and other functions will also return errors).

* libdw: Handle DWARF5 line tables in dwarf_getsrclines.Mark Wielaard2018-05-1110-104/+646
| | | | | | | | | | | | | | | | | | | | | | | | | | | In DWARF5 the actual line number table format doesn't change, except for not allowing DW_LNE_define_file (but we still just accept it). The changes are the header having new fields for address and segment selector sizes, and new formats for the directory and file names tables. The directory and file name tables are much more flexible in DWARF5, but we only interpret the actual names and file/dir index relationships, skipping/ignoring any other information. There also is no new interface yet to get at the new directory and file properties. There is some small confusion about the file name table indexing. Older DWARF versions explicitly called the first file name table 1. DWARF5 implies the first index is 0 (but for file attributes, zero means not associated with a file). We get away with that by having an actual zero index for older DWARF versions (the null_fill). It looks like gcc gets around it by explicitly duplicating the first (0) and second (1) file name entry in the table. This can also be seen in the new testcase. The patch looks big because of moving a few initializations around and because the code that is different for older/newer DWARF got moved under if statements. But the original old DWARF code path didn't really change. Signed-off-by: Mark Wielaard <[email protected]>
