2020-01-26Virtualize "readin" and "compunit_symtab"Tom Tromey1-3/+3
This patch removes the "readin" and "compunit_symtab" members from partial_symtab, replacing them with methods. Then it introduces a new "standard_psymtab" class, which restores these members; and changes the symbol readers to use this intermediate class as the base class of their partial symtab subclasses. The reason for this is to make it possible for a symbol reader to implement an alternate mapping between partial and full symbol tables. This is important in order to be able to share psymtabs across objfiles -- whether a psymtab has been "readin" is objfile-dependent, as are the pointers to the full symbol tables. gdb/ChangeLog 2020-01-26 Tom Tromey <tom@tromey.com> * psymtab.c (partial_map_expand_apply) (psym_find_pc_sect_compunit_symtab, psym_lookup_symbol) (psymtab_to_symtab, psym_find_last_source_symtab, dump_psymtab) (psym_print_stats, psym_expand_symtabs_for_function) (psym_map_symbol_filenames, psym_map_matching_symbols) (psym_expand_symtabs_matching) (partial_symtab::read_dependencies, maintenance_info_psymtabs) (maintenance_check_psymtabs): Use new methods. * psympriv.h (struct partial_symtab) <readin_p, get_compunit_symtab>: New methods. <readin, compunit_symtab>: Remove members.

2020-01-26Introduce partial_symtab::expand_psymtab methodTom Tromey1-0/+1
The symbol readers generally used two functions to expand a partial symtab: an outer function (now the "read_symtab" method), and an inner function, typically named something like "psymtab_to_symtab". This patch changes this second step to be a method on partial_symtab, and updates all the callers. For legacy_psymtab, a new function pointer member is introduced. This patch enables a subsequent cleanup. gdb/ChangeLog 2020-01-26 Tom Tromey <tom@tromey.com> * xcoffread.c (xcoff_psymtab_to_symtab_1): Change argument order. Call expand_psymtab.

2020-01-26Introduce partial_symtab::read_symtab methodTom Tromey1-2/+22
This introduces a new partial_symtab::read_symtab method, and updates the symbol readers to subclass partial_symtab and implement this method. The old read_symtab and read_symtab_private members are removed. In practice, only DWARF and CTF are truly updated to take advantage of the new setup. The other symbol readers are less actively maintained, and so this patch also introduces a "legacy_psymtab", which essentially works the same way as the old partial_symtab. (Note that, without more knowledge of the interaction between these symbol readers, fixing this to remove the new (small) overhead is not trivial, because these readers copy the read_symtab pointer between partial symtabs.) gdb/ChangeLog 2020-01-26 Tom Tromey <tom@tromey.com> * xcoffread.c (this_symtab_psymtab, read_xcoff_symtab) (xcoff_psymtab_to_symtab_1, xcoff_read_symtab) (xcoff_start_psymtab, xcoff_end_psymtab, scan_xcoff_symtab): Use legacy_symtab. * stabsread.h (dbx_end_psymtab): Use legacy_symtab. * psymtab.c (psymtab_to_symtab): Call method.

2020-01-13Dwarf 5: Handle debug_str_offsets and indexed attributes that have base offsets.Ali Tamur1-0/+1
* Process debug_str_offsets section. Handle DW_AT_str_offsets_base attribute and keep the value in dwarf2_cu. * Make addr_base field in dwarf2_cu optional to disambiguate 0 value (absent or present and 0). * During parsing, there is no guarantee that DW_AT_str_offsets_base and DW_AT_rnglists_base fields will be processed before the attributes that need those values for correct computation. So make two passes, on the first one mark the attributes that depend on *_base attributes and process only the others. On the second pass, only process the attributes that are marked on the first pass. * For string attributes, differentiate between addresses that directly point to a string and those that point to an offset in debug_str_offsets section. * There are now two attributes, DW_AT_addr_base and DW_AT_GNU_addr_base to read address offset base. Likewise, there are two attributes, DW_AT_rnglists_base and DW_AT_GNU_ranges_base to read ranges base. Since there is no guarantee which ones the compiler will generate, create helper functions to handle all cases. Tested with CC=/usr/bin/gcc (version 8.3.0) against master branch (also with -gsplit-dwarf and -gdwarf-4 flags) and there was no increase in the set of tests that fails. (gdb still cannot debug a 'hello world' program with DWARF 5, so for the time being, this is all we care about). This is part of an effort to support DWARF-5 in gdb.

2019-11-27Remove some unnecessary backslashesTom Tromey1-2/+2
I found a couple of unnecessary backslashes in gdb. This removes them. Offhand, I wonder whether this abstract_to_concrete thing could be done some other way? This seems possibly expensive. Anyway, tested by rebuilding. I'm going to check this in as obvious. gdb/ChangeLog 2019-11-27 Tom Tromey <tromey@adacore.com> * dwarf2read.h (struct dwarf2_per_objfile): Remove unnecessary backslashes. * cp-support.c: Remove unnecessary backslashes.

2019-10-15gdb: Remove use of VEC from dwarf2read.cAndrew Burgess1-5/+39
This removes a use of VEC from GDB, from dwarf2read.c. This removal is not very clean, and would probably benefit from additional refactoring in the future. The problem here is that the VEC is contained within struct dwarf2_per_cu_data, which is treated as POD in dwarf2read.c. As such it is actually a VEC pointer. When converting this to a std::vector in an ideal world we would not use a std::vector pointer, and use the std::vector directly. Sadly, to do that would require some rewriting in dwarf2read.c - my concern would be introducing bugs during this rewrite. If we move to a std::vector pointer then we need to take care to handle the case where the pointer is null. The old VEC library would handle null for us, making the VEC interface very clean. With std::vector we need to handle the null pointer case ourselves. The achieve this then I've added a small number of function that wrap up access to the std::vector, hopefully hiding the null pointer management. The final ugliness with this conversion is that, ideally, when wrapping a data member behind an interface I would make the data member private, however, treating the structure as POD once again prevents this, so we are left with the data member being public, but access (ideally) being through the published interface functions. There should be no user visible changes after this commit. gdb/ChangeLog: * gdb/dwarf2read.c (dwarf2_per_objfile::~dwarf2_per_objfile): Update for new std::vector based implementation.

2019-10-02Handle copy relocationsTom Tromey1-2/+8
In ELF, if a data symbol is defined in a shared library and used by the main program, it will be subject to a "copy relocation". In this scenario, the main program has a copy of the symbol in question, and a relocation that tells ld.so to copy the data from the shared library. Then the symbol in the main program is used to satisfy all references. This patch changes gdb to handle this scenario. Data symbols coming from ELF shared libraries get a special flag that indicates that the symbol's address may be subject to copy relocation. I looked briefly into handling copy relocations by looking at the actual relocations in the main program, but this seemed difficult to do with BFD. Note that no caching is done here. Perhaps this could be changed if need be; I wanted to avoid possible problems with either objfile lifetimes and changes, or conflicts with the long-term (vapor-ware) objfile splitting project. gdb/ChangeLog 2019-10-02 Tom Tromey <tromey@adacore.com> * symmisc.c (dump_msymbols): Don't use MSYMBOL_VALUE_ADDRESS. * ada-lang.c (lesseq_defined_than): Handle LOC_STATIC. * dwarf2read.c (dwarf2_per_objfile): Add can_copy parameter.

2019-07-09Rename common to gdbsupportTom Tromey1-1/+1
This is the next patch in the ongoing series to move gdbsever to the top level. This patch just renames the "common" directory. The idea is to do this move in two parts: first rename the directory (this patch), then move the directory to the top. This approach makes the patches a bit more tractable. I chose the name "gdbsupport" for the directory. However, as this patch was largely written by sed, we could pick a new name without too much difficulty.

FAIL: gdb.dwarf2/varval.exp: print varval2 ... with boards readnow/cc-with-gdb-index/cc-with-debug-names, as well as if gdb is build with -fsanitize=address -lasan. The problem is that the abstract_to_concrete map in which we track the association of abstract to concrete DIEs (for DW_OP_GNU_variable_value support) has type std::unordered_map<die_info_ptr, std::vector<die_info_ptr>>, and the die_info_ptrs that we register in the map may be invalid by the time that we start to lookup DIEs in the map. Fix this by using the sect_offset instead to identify the DIEs in the map.

2019-06-16Write index for dwz -m fileSimon Marchi1-0/+38
PR 24445 ("dwz multifile index not written to index cache") exposed the fact that we are not doing things right when we generate an index for an object file that has is linked to a dwz file. The same happens whether the index is generated with the intent of populating the index cache or using the save gdb-index command. The problem can be observed when running these tests with the cc-with-dwz-m board: FAIL: gdb.base/index-cache.exp: test_cache_enabled_hit: check index-cache stats FAIL: gdb.dwarf2/gdb-index.exp: index used FAIL: gdb.dwarf2/gdb-index.exp: index used after symbol reloading When generating the index for such file and inspecting the CU list of the resulting index (with readelf --debug-dump=gdb_index), we can see something like: CU table: [ 0] 0x0 - 0xb9 [ 1] 0x0 - 0x44 This is supposed to be a sorted list of the ranges of all CUs in the file this index represents, so already having some overlap is a red flag. It turns out that we save the ranges of CUs coming from both the main file and the dwz file in the same index. After digging a little bit, it became quite obvious that the index in the main file should only list the CUs present in the main file, and a separate index should be generated for the dwz file, listing the CUs present in that file. First, that's what happens if you run dwz on a file that already has a GDB index embedded. Second, dwarf2read.c has code to read an index from a dwz file. The index in the dwz file is actually required to be present, if the main file has an index. So this patch changes write_psymtabs_to_index to generate an index for the dwz file, if present. That index only contains a CU list, just like what the dwz tool does when processing a file that already contains an index. Some notes about the implementation: - The file management (creating a temp file, make sure it's close/removed on error - in the right order) is a bit heavy in write_psymtabs_to_index, and I needed to add a third file. I factored this pattern in a separate class, index_wip_file. - It became a bit tedious to keep the call to assert_file_size in write_psymtabs_to_index, write_gdbindex would have had to return two sizes. Instead, I moved the calls to assert_file_size where the file is written. The downside is that we lose the filename at this point, but it was only used for the very improbable case of ftell failing, so I think it's not a problem. - The actual writing of the index file is factored out to write_gdbindex_1, so it can be re-used for both index files. - While the "save gdb-index" command will now write two .gdb-index files, this patch does not update the gdb-add-index.sh script, this will come in a later patch. gdb/ChangeLog: YYYY-MM-DD Simon Marchi <simon.marchi@efficios.com> PR gdb/24445 * dwarf-index-write.h (write_psymtabs_to_index): Add dwz_basename parameter. * dwarf-index-write.c (write_gdbindex): Move file writing to write_gdbindex_1.

This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files.
2018-09-05[gdb/exp] Handle DW_OP_GNU_variable_value refs to abstract diesTom de Vries1-0/+8
Consider a vla variable 'a' in function f1: ... <2><1a7>: Abbrev Number: 11 (DW_TAG_variable) <1a8> DW_AT_description : a <1aa> DW_AT_abstract_origin: <0x311> ... with abstract origin 'a': ... <2><311>: Abbrev Number: 3 (DW_TAG_variable) <312> DW_AT_name : a <317> DW_AT_type : <0x325> ... and inherited abstract vla type: ... <1><325>: Abbrev Number: 9 (DW_TAG_array_type) <326> DW_AT_type : <0x33a> <2><32e>: Abbrev Number: 10 (DW_TAG_subrange_type) <32f> DW_AT_type : <0x2ea> <333> DW_AT_upper_bound : 5 byte block: fd 1b 3 0 0 (DW_OP_GNU_variable_value: <0x31b>) ... where the upper bound refers to this artificial variable D.1922 without location attribute: ... <2><31b>: Abbrev Number: 8 (DW_TAG_variable) <31c> DW_AT_description : (indirect string, offset: 0x39a): D.1922 <320> DW_AT_type : <0x2ea> <324> DW_AT_artificial : 1 ... Currently, when we execute "p sizeof (a)" in f1, the upper bound is calculated by evaluating the DW_OP_GNU_variable_value expression referring to D.1922, but since that die doesn't have a location attribute, we get: ... value has been optimized out ... However, there's also artificial variable D.4283 that is sibling of vla variable 'a', has artificial variable D.1922 as abstract origin, and has a location attribute: ... <2><1ae>: Abbrev Number: 12 (DW_TAG_variable) <1af> DW_AT_description : (indirect string, offset: 0x1f8): D.4283 <1b3> DW_AT_abstract_origin: <0x31b> <1b7> DW_AT_location : 11 byte block: 75 1 8 20 24 8 20 26 31 1c 9f (DW_OP_breg5 (rdi):1; DW_OP_const1u: 32; DW_OP_shl; DW_OP_const1u: 32; DW_OP_shra; DW_OP_lit1; DW_OP_minus; DW_OP_stack_value) ... The intended behaviour for DW_OP_GNU_variable_value is to find a die that refers to D.1922 as abstract origin, has a location attribute and is 'in scope', so the expected behaviour is: ... $1 = 6 ... The 'in scope' concept can be thought of as variable D.1922 having name attribute "D.1922", and variable D.4283 inheriting that attribute, resulting in D.4283 being declared with name "D.1922" alongside vla a in f1, and when we lookup "DW_OP_GNU_variable_value D.1922", it should work as if we try to find the value of a variable named "D.1922" on the gdb command line using "p D.1922", and we should return the value of D.4283. This patch fixes the case described above, by: - adding a field abstract_to_concrete to struct dwarf2_per_objfile, - using that field to keep track of which concrete dies are instances of an abstract die, and - using that information when getting the value DW_OP_GNU_variable_value.

2018-08-07Add DWARF index cacheSimon Marchi1-0/+5
New in v3: - Remove things related to the dwarf-5 format. - Fix compilation on mingw (scoped_mmap.c). GDB can generate indexes for DWARF debug information, which, when integrated in the original binary, can speed up loading object files. This can be done using the gdb-add-index script or directly by the linker itself. However, not many people know about this. And even among those who do, because it requires additional steps, I don't know a lot of people who actually go through that trouble. To help make using the DWARF index more transparent, this patch introduces a DWARF index cache. When enabled, loading an index-less binary in GDB will automatically save an index file in ~/.cache/gdb. When loading that same object file again, the index file will be looked up and used to load the DWARF index. You therefore get the benefit of the DWARF index without having to do additional manual steps or modifying your build system. When an index section is already present in the file, GDB will prefer that one over looking up the cache. When doing my edit-compile-debug cycle, I often debug multiple times the same build, so the cache helps reducing the load time of the debug sessions after the first one. - The saved index file is exactly the same as the output of the "save gdb-index" command. It is therefore the exact same content that would be found in the .gdb_index or .debug_names section. We just leave it as a standalone file instead of merging it in the binary. - The cache is just a directory with files named after the object file's build-id. It is not possible to save/load the index for an object file without build-id in the cache. - The cache uses the gdb index format. The problem with the dwarf-5 format is that we can generate an addendum to the .debug_str section that you're supposed to integrate to the original binary. This complicates a little bit loading the data from the cached index files, so I would leave this for later. - The size taken up by ~/.cache/gdb is not limited. I was thinking we could add configurable limit (like ccache does), but that would come after. Also, maybe a command to flush the cache. - The cache is disabled by default. I think once it's been out there and tested for a while, it could be turned on by default, so that everybody can enjoy it. - The code was made to follow the XDG specification: if the XDG_CACHE_HOME environment variable, it is used, otherwise it falls back to ~/.cache/gdb. It is possible to change it using "set index-cache directory". On other OSes than GNU/Linux, ~/.cache may not be the best place to put such data. On macOS it should probably default to ~/Library/Caches/... On Windows, %LocalAppData%/... I don't intend to do this part, but further patches are welcome. - I think that we need to be careful that multiple instances of GDB don't interfere with each other (not far fetched at all if you run GDB in some automated script) and the cache is always coherent (either the file is not found, or it is found and entirely valid). Writing the file directly to its final location seems like a recipe for failure. One GDB could read a file in the index while it is being written by another GDB. To mitigate this, I made write_psymtabs_to_index write to temporary files and rename them once it's done. Two GDB instances writing the index for the same file should not step on each other's toes (the last file to be renamed will stay). A GDB looking up a file will only see a complete file or no file. Also, if GDB crashes while generating the index file, it will leave a work-in-progress file, but it won't be picked up by other instances looking up in the cache. gdb/ChangeLog: * common/pathstuff.h (get_standard_cache_dir): New. * common/pathstuff.c (get_standard_cache_dir): New. * build-id.h (build_id_to_string): New. * dwarf-index-common.h (INDEX4_SUFFIX, INDEX5_SUFFIX, DEBUG_STR_SUFFIX): Move to here. * dwarf-index-write.c (INDEX4_SUFFIX, INDEX5_SUFFIX, DEBUG_STR_SUFFIX): Move from there.

2018-07-26gdb: Add switch to disable DWARF stack unwindersAndrew Burgess1-0/+4
Add a maintenance command to disable the DWARF stack unwinders. Normal users would not need this feature, but it is useful to allow extended testing of fallback stack unwinding strategies, for example, prologue scanners. This is a partial implementation of the idea discussed in pr gdb/8434, which talks about a generic ability to disable any frame unwinder. Being able to arbitrarily disable any frame unwinder would be a more complex patch, and I was unsure how useful such a feature would really be, however, I can see (and have) a real need to disable DWARF unwinders. That's why this patch only targets that specific set of unwinders. If in the future we find ourselves adding more switches to disable different unwinders, then we should probably move to a more generic solution, and remove this patch. gdb/ChangeLog: * dwarf2-frame-tailcall.c (tailcall_frame_sniffer): Exit early if DWARF unwinders are disabled. * dwarf2-frame.c: Add dwarf2read.h include.

2018-03-27Move DWARF index-related things to a separate fileSimon Marchi1-0/+375
I want to add a DWARF index-related feature (automatically produce index files when loading objfiles in GDB), but I don't want to add many hundred lines to the already too big dwarf2read.c. I thought it would be a logical split to move everything related to the DWARF index to its own file. I first tried to move everything that reads and writes DWARF indices to a separate file, but found that the "read" part is a little bit entangled with the rest of dwarf2read.c, so the line is hard to draw about where to split. The write part is quite isolated though, so I moved this part to a new file, dwarf-index-write.c. Some things are necessary to both reading and writing indices, so I placed them in dwarf-index-common.{c,h}. The idea would be to have a dwarf-index-read.c eventually that would use it too (for now that code is still in dwarf2read.c). This required moving some things to a new dwarf2read.h header, so they can be read by the code that writes the index. The patch is big in number of lines, but it's all existing code being moved around. The only changes are that some functions are not static anymore, a declaration is added in a .h file, and therefore the comment is moved there. I built-tested it with a little and big endian target. This patch is also available on the users/simark/split-dwarf2read branch. gdb/ChangeLog: * Makefile.in (COMMON_SFILES): Add dwarf-index-common.c and dwarf-index-write.c (HFILES_NO_SRCDIR): Add dwarf-index-common.h and dwarf2read.h. * dwarf-index-common.c: New file. * dwarf-index-common.h: New file. * dwarf-index-write.c: New file. * dwarf2read.c: Include dwarf2read.h and dwarf-index-common.h.
