2020-03-10gdb: Add support for tracking the DWARF line table is-stmt fieldAndrew Burgess1-1/+13
This commit brings support for the DWARF line table is_stmt field to GDB. The is_stmt field is used by the compiler when a single source line is split into multiple assembler instructions, especially if the assembler instructions are interleaved with instruction from other source lines. The compiler will set the is_stmt flag false from some instructions from the source lines, these instructions are not a good place to insert a breakpoint in order to stop at the source line. Instructions which are marked with the is_stmt flag true are a good place to insert a breakpoint for that source line. Currently GDB ignores all instructions for which is_stmt is false. This is fine in a lot of cases, however, there are some cases where this means the debug experience is not as good as it could be. Consider stopping at a random instruction, currently this instruction will be attributed to the last line table entry before this point for which is_stmt was true - as these are the only line table entries that GDB tracks. This can easily be incorrect in code with even a low level of optimisation. With is_stmt tracking in place, when stopping at a random instruction we now attribute the instruction back to the real source line, even when is_stmt is false for that instruction in the line table. When inserting breakpoints we still select line table entries for which is_stmt is true, so the breakpoint placing behaviour should not change. When stepping though code (at the line level, not the instruction level) we will still stop at instruction where is_stmt is true, I think this is more likely to be the desired behaviour. Instruction stepping is, of course, unchanged, stepping one instruction at a time, but we should now report more accurate line table information with each instruction step. The original motivation for this work was a patch posted by Bernd here: https://sourceware.org/ml/gdb-patches/2019-11/msg00792.html As part of that thread it was suggested that many issues would be resolved if GDB supported line table views, this isn't something I've attempted in this patch, though reading the spec, it seems like this would be a useful feature to support in GDB in the future. The spec is here: http://dwarfstd.org/ShowIssue.php?issue=170427.1 And Bernd gives a brief description of the benefits here: https://sourceware.org/ml/gdb-patches/2020-01/msg00147.html With that all said, I think that there is benefit to having proper is_stmt support regardless of whether we have views support, so I think we should consider getting this in first, and then building view support on top of this. The gdb.cp/step-and-next-inline.exp test is based off a test proposed by Bernd Edlinger in this message: https://sourceware.org/ml/gdb-patches/2019-12/msg00842.html gdb/ChangeLog: * buildsym-legacy.c (record_line): Pass extra parameter to record_line. * buildsym.c (buildsym_compunit::record_line): Take an extra parameter, reduce duplication in the line table, and record the is_stmt flag in the line table. * buildsym.h (buildsym_compunit::record_line): Add extra parameter. * disasm.c (do_mixed_source_and_assembly_deprecated): Ignore non-statement lines. * dwarf2/read.c (dwarf_record_line_1): Add extra parameter, pass this to the symtab builder.

2020-03-04Introduce objfile::internTom Tromey1-1/+1
This introduces a string cache on the per-BFD object, replacing the macro and filename caches. Both of these caches just store strings, so this consolidation by itself saves a little memory (about the size of a bcache per objfile). Then this patch switches some allocations on the objfile obstack to use this bcache instead. This saves more space; and turns out to be a bit faster as well. Here are the before and after "maint time" + "maint space" results of "file ./gdb": Command execution time: 4.664021 (cpu), 4.728518 (wall) Space used: 39190528 (+29212672 for this command) Command execution time: 4.216209 (cpu), 4.107023 (wall) Space used: 36667392 (+26689536 for this command) The main interface to the string cache is a new pair of overloaded methods, objfile::intern. gdb/ChangeLog 2020-03-04 Tom Tromey <tom@tromey.com> * symmisc.c (print_symbol_bcache_statistics) (print_objfile_statistics): Update. * symfile.c (allocate_symtab): Use intern. * psymtab.c (partial_symtab::partial_symtab): Use intern. * objfiles.h (struct objfile_per_bfd_storage) <filename_cache, macro_cache>: Remove. <string_cache>: New member.

2020-01-24gdb: Don't reorder line table entries too much when sorting.Andrew Burgess1-24/+16
Don't reorder line table entries for the same address when sorting the line table, maintain the compiler given line order. Usually this will reflect the order in which lines are conceptually encountered at a given address. Consider this example: /* 1 */ volatile int global_var; /* 2 */ int __attribute__ ((noinline)) /* 3 */ bar () /* 4 */ { /* 5 */ return global_var; /* 6 */ } /* 7 */ static inline int __attribute__ ((always_inline)) /* 8 */ foo () /* 9 */ { /* 10 */ return bar (); /* 11 */ } /* 12 */ int /* 13 */ main () /* 14 */ { /* 15 */ global_var = 0; /* 16 */ return foo (); /* 17 */ } GCC 10 currently generates a line table like this (as shown by objdump): CU: ./test.c: File name Line number Starting address test.c 4 0x4004b0 test.c 5 0x4004b0 test.c 6 0x4004b6 test.c 6 0x4004b7 test.c 14 0x4003b0 test.c 15 0x4003b0 test.c 16 0x4003ba test.c 10 0x4003ba test.c 10 0x4003c1 The interesting entries are those for lines 16 and 10 at address 0x4003ba, these represent the call to foo and the inlined body of foo. With the current line table sorting GDB builds the line table like this (as shown by 'maintenance info line-table'): INDEX LINE ADDRESS 0 14 0x00000000004003b0 1 15 0x00000000004003b0 2 10 0x00000000004003ba 3 16 0x00000000004003ba 4 END 0x00000000004003c1 5 4 0x00000000004004b0 6 5 0x00000000004004b0 7 END 0x00000000004004b7 Notice that entries 2 and 3 for lines 10 and 16 are now in a different order to the line table as given by the compiler. With this patch applied the order is now: INDEX LINE ADDRESS 0 14 0x00000000004003b0 1 15 0x00000000004003b0 2 16 0x00000000004003ba 3 10 0x00000000004003ba 4 END 0x00000000004003c1 5 4 0x00000000004004b0 6 5 0x00000000004004b0 7 END 0x00000000004004b7 Notice that entries 2 and 3 are now in their original order again. The consequence of the incorrect ordering is that when stepping through inlined functions GDB will display the wrong line for the inner most frame. Here's a GDB session before this patch is applied: Starting program: /home/andrew/tmp/inline/test Temporary breakpoint 1, main () at test.c:15 15 /* 15 */ global_var = 0; (gdb) step 16 /* 16 */ return foo (); (gdb) step foo () at test.c:16 16 /* 16 */ return foo (); (gdb) step bar () at test.c:5 5 /* 5 */ return global_var; The step from line 15 to 16 was fine, but the next step should have taken us to line 10, instead we are left at line 16. The final step to line 5 is as expected. With this patch applied the session goes better: Starting program: /home/andrew/tmp/inline/test Temporary breakpoint 1, main () at test.c:15 15 /* 15 */ global_var = 0; (gdb) step 16 /* 16 */ return foo (); (gdb) step foo () at test.c:10 10 /* 10 */ return bar (); (gdb) step bar () at test.c:5 5 /* 5 */ return global_var; We now visit the lines as 15, 16, 10, 5 as we would like. The reason for this issue is that the inline frame unwinder is detecting that foo is inlined in main. When we stop at the shared address 0x4003ba the inline frame unwinder first shows us the outer frame, this information is extracted from the DWARF's DW_TAG_inlined_subroutine entries and passed via GDB's block data. When we step again the inlined frame unwinder moves us up the call stack to the inner most frame at which point the frame is displayed as normal, with the location for the address being looked up in the line table. As GDB uses the last line table entry for an address as "the" line to report for that address it is critical that GDB maintain the order of the line table entries. In the first case, by reordering the line table we report the wrong location. I had to make a small adjustment in find_pc_sect_line in order to correctly find the previous line in the line table. In some line tables I was seeing an actual line entry and an end of sequence marker at the same address, before this commit these would reorder to move the end of sequence marker before the line entry (end of sequence has line number 0). Now the end of sequence marker remains in its correct location, and in order to find a previous line we should step backward over any end of sequence markers. As an example, the binary: gdb/testsuite/outputs/gdb.dwarf2/dw2-ranges-func/dw2-ranges-func-lo-cold Has this line table before the patch: INDEX LINE ADDRESS 0 48 0x0000000000400487 1 END 0x000000000040048e 2 52 0x000000000040048e 3 54 0x0000000000400492 4 56 0x0000000000400497 5 END 0x000000000040049a 6 62 0x000000000040049a 7 END 0x00000000004004a1 8 66 0x00000000004004a1 9 68 0x00000000004004a5 10 70 0x00000000004004aa 11 72 0x00000000004004b9 12 END 0x00000000004004bc 13 76 0x00000000004004bc 14 78 0x00000000004004c0 15 80 0x00000000004004c5 16 END 0x00000000004004cc And after this patch: INDEX LINE ADDRESS 0 48 0x0000000000400487 1 52 0x000000000040048e 2 END 0x000000000040048e 3 54 0x0000000000400492 4 56 0x0000000000400497 5 END 0x000000000040049a 6 62 0x000000000040049a 7 66 0x00000000004004a1 8 END 0x00000000004004a1 9 68 0x00000000004004a5 10 70 0x00000000004004aa 11 72 0x00000000004004b9 12 END 0x00000000004004bc 13 76 0x00000000004004bc 14 78 0x00000000004004c0 15 80 0x00000000004004c5 16 END 0x00000000004004cc When calling find_pc_sect_line with the address 0x000000000040048e, in both cases we find entry #3, we then try to find the previous entry, which originally found this entry '2 52 0x000000000040048e', after the patch it finds '2 END 0x000000000040048e', which cases the lookup to fail. By skipping the END marker after this patch we get back to the correct entry, which is now #1: '1 52 0x000000000040048e', and everything works again. gdb/ChangeLog: * buildsym.c (lte_is_less_than): Delete.

This removes code that was present from the very first git revisison 7b4ac7e1ed2c4616bce56d1760807798be87ac9e from 1988. It was in the gdb/dbxread.c at the time (and makes more sense for dbx line info format since line numbers are 16-bit entities in that debug format and debugging files with more than 65535 lines would not work anyway) but moved from there to gdb/buildsym.c which is used for dwarf line info as well, and excluding an arbitrary line number does certainly not make sense nowadays.

2019-01-10gdb/23712: Use new multidictionary APIKeith Seitz1-15/+13
This patch builds on the previous by enabling the `new' multidictionary API. A lot of the hunks are simply textual replacements of "dict_" with "mdict_" and similar transformations. A word of warning, even with the use of multidictionaries, the code still does not satisfactorily fix the reported problems with gdb/23712 (or gdb/23010). We still have additional changes to make before that happens. gdb/ChangeLog: PR gdb/23712 PR symtab/23010 * dictionary.h (struct dictionary): Replace declaration with multidictionary. (dict_create_hashed, dict_create_hashed_expandable) (dict_create_linear, dict_create_linear_expandable) (dict_free, dict_add_symbol, dict_add_pending, dict_empty) (dict_iterator_first, dict_iterator_next, dict_iter_match_first) (dict_iter_match_next, dict_size): Rename to "mdict_" versions taking multidictionary argument. [ALL_DICT_SYMBOLS]: Update for multidictionary. * block.h (struct block) <dict>: Change to multidictionary and rename `multidict'. * block.c, buildsym.c, jit.c, mdebugread.c, objfiles.c, symmisc.c: Update all dictionary references to multidictionary.

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.
2018-07-20Rename remaining members of buildsym_compunit to start with "m_"Keith Seitz1-48/+48
This renames all the remaining members of buildsym_compunit to start with "m_" to follow the general naming convention. gdb/ChangeLog 2018-07-20 Keith Seitz <keiths@redhat.com> * buildsym.h (struct buildsym_compunit) <m_objfile, m_subfiles, m_main_subfile, m_comp_dir, m_producer, m_debugformat, m_compunit_symtab, m_language>: Add "m_" prefix. Update all uses. * buildsym.c: Update all uses.
2018-07-20Introduce buildsym-legacy.hTom Tromey1-407/+1
This introduces a new header, buildsym-legacy.h, and changes all the symbol readers to use it. The idea is to put the function-based interface, that relies on the buildsym_compunit global, into a separate header. Then when a symbol reader is updated to use the new interface, it can simply not include buildsym-legacy.h, so it's easy to be sure that the new API is used everywhere. gdb/ChangeLog 2018-07-20 Tom Tromey <tom@tromey.com> * xcoffread.c: Include buildsym-legacy.h. * windows-nat.c: Include buildsym-legacy.h. * stabsread.c: Include buildsym-legacy.h. * mdebugread.c: Include buildsym-legacy.h. * buildsym-legacy.h: New file. * buildsym-legacy.c: New file, from buildsym.c. * go32-nat.c: Include buildsym-legacy.h. * dwarf2read.c: Include buildsym-legacy.h. * dbxread.c: Include buildsym-legacy.h. * cp-namespace.c: Include buildsym-legacy.h. * coffread.c: Include buildsym-legacy.h. * buildsym.h: Move some contents to buildsym-legacy.h. * buildsym.c: Include buildsym-legacy.h. Move many functions to buildsym-legacy.c. * Makefile.in (HFILES_NO_SRCDIR): Add buildsym-legacy.h.
2018-07-20Move struct buildsym_compunit to buildsym.hTom Tromey1-344/+69
This moves struct buildsym_compunit to buildsym.h. Now that the members are private, and it no longer affects any global state in buildsym.c, an instance can be used directly for symtab creation. gdb/ChangeLog 2018-07-20 Tom Tromey <tom@tromey.com> * buildsym.h (struct buildsym_compunit): Move from buildsym.c. * buildsym.c (struct buildsym_compunit): Move to buildsym.h. (buildsym_compunit::buildsym_compunit) (buildsym_compunit::~buildsym_compunit) (buildsym_compunit::get_macro_table): Define.
2018-07-20Remove reset_symtab_globalsTom Tromey1-16/+4
This patch arranges for the remaining buildsym global -- buildsym_compunit -- to only be cleared by the wrapper functions, not by methods on struct buildsym_compunit. In the process, reset_symtab_globals is removed. gdb/ChangeLog 2018-07-20 Tom Tromey <tom@tromey.com> * buildsym.c (reset_symtab_globals): Remove. (buildsym_compunit::end_symtab_from_static_block): Update. (buildsym_compunit::augment_type_symtab): Update. (end_symtab_from_static_block): Call free_buildsym_compunit. (augment_type_symtab, end_symtab, end_expandable_symtab): Likewise.
2018-07-20Add many methods to buildsym_compunitTom Tromey1-188/+427
This adds many methods to buildsym_compunit and makes the data members private. Essentially the entire buildsym API is now available as a method on buildsym_compunit. However, standalone functions are still provided, as this is what the sybmol readers actually use. gdb/ChangeLog 2018-07-20 Tom Tromey <tom@tromey.com> * buildsym.c (buildsym_compunit::buildsym_compunit): Do more initialization. (buildsym_compunit): Add new constructor.

Update all users.
2018-07-20Remove parameter from record_pending_blockTom Tromey1-34/+25
This removes a redundant parameter from record_pending_block. It also moves record_pending_block earlier in the file, so that a forward declaration is no longer needed. gdb/ChangeLog 2018-07-20 Tom Tromey <tom@tromey.com> * buildsym.c (record_pending_block): Move earlier. Remove objfile parameter. (finish_block_internal): Update.
2018-07-20Remove EXTERN from buildsym.hTom Tromey1-6/+1
Nothing in buildsym.h relies on the "EXTERN" method of declaration/definition, so remove the traces. gdb/ChangeLog 2018-07-20 Tom Tromey <tom@tromey.com> * buildsym.h (EXTERN): Don't define or undef. * buildsym.c (EXTERN): Don't define.
2018-07-20Remove a TODOTom Tromey1-2/+1
This removes a TODO comment -- the work has been done. gdb/ChangeLog 2018-07-20 Tom Tromey <tom@tromey.com> * buildsym.c: Remove TODO comment.
2018-07-20Remove buildsym_initTom Tromey1-35/+7
Now that buildsym_init does nothing, it can be removed. gdb/ChangeLog 2018-07-20 Tom Tromey <tom@tromey.com> * coffread.c (coff_symtab_read): Update. * xcoffread.c (xcoff_psymtab_to_symtab_1): Update.

2018-07-20Move the symbol lists to buildsym_compunitTom Tromey1-42/+65
This moves the global symbol lists into buildsym_compunit, adds accessors, and updates all the users. gdb/ChangeLog 2018-07-20 Tom Tromey <tom@tromey.com> * xcoffread.c (read_xcoff_symtab, process_xcoff_symbol): Update. * stabsread.c (patch_block_stabs, define_symbol, read_type) (read_enum_type, common_block_start, common_block_end) (cleanup_undefined_types_1, finish_global_stabs): Update. * mdebugread.c (psymtab_to_symtab_1): Update. * dwarf2read.c (fixup_go_packaging, read_func_scope) (read_lexical_block_scope, new_symbol): Update. * dbxread.c (process_one_symbol): Update. * coffread.c (coff_symtab_read, process_coff_symbol) (coff_read_enum_type): Update. * buildsym.h (file_symbols, global_symbols, local_symbols): Don't declare.

2018-07-20Remove free_pendingsTom Tromey1-25/+3
buildsym.c currently keeps a free list of "struct pending"s. However, this didn't seem necessary to me, and so this patch removes the free list. gdb/ChangeLog 2018-07-20 Tom Tromey <tom@tromey.com> * buildsym.c (free_pendings): Remove. (add_symbol_to_list, scoped_free_pendings) (finish_block_internal, buildsym_init): Update.
2018-07-20Remove the "listhead" argument from finish_blockTom Tromey1-3/+2
finish_block is only ever called with "&local_symbols" as the "listhead" argument. So, remove this argument. gdb/ChangeLog 2018-07-20 Tom Tromey <tom@tromey.com> * xcoffread.c (read_xcoff_symtab): Update. * dwarf2read.c (read_func_scope, read_lexical_block_scope): Update. * dbxread.c (process_one_symbol): Update. * coffread.c (coff_symtab_read): Update. * buildsym.h (finish_block): Update. * buildsym.c (finish_block): Remove "listhead" argument. (end_symtab_get_static_block): Update.
2018-07-20Move pending_blocks and pending_block_obstack to buildsym_compunitTom Tromey1-50/+34
This moves the pending_blocks and pending_block_obstack into buildsym_compunit. The obstack could perhaps be merged with the addrmap obstack, but I did not do that in this series. gdb/ChangeLog 2018-07-20 Tom Tromey <tom@tromey.com> * buildsym.h (class scoped_free_pendings): Remove constructor. * buildsym.c (struct buildsym_compunit) <free_pending_blocks>: New method. <m_pending_block_obstack, m_pending_blocks>: New members.

2018-07-20Move pending addrmap globals to buildsym_compunitTom Tromey1-37/+26
This moves the pending addrmap-related globals into buildsym_compunit. gdb/ChangeLog 2018-07-20 Tom Tromey <tom@tromey.com> * buildsym.c (struct buildsym_compunit) <m_pending_addrmap, m_pending_addrmap_obstack, m_pending_addrmap_interesting>: New members.

2018-07-20Move the context stack to buildsym_compunitTom Tromey1-39/+51
This moves the context stack globals to be members of buildsym_compunit, changing the type to a std::vector in the process. Because the callers expect the context stack object to be valid after being popped, at Simon's suggestion I've changed pop_context to return the object rather than the pointer. gdb/ChangeLog 2018-07-20 Tom Tromey <tom@tromey.com> * coffread.c (coff_symtab_read): Update. * xcoffread.c (read_xcoff_symtab): Update. * dwarf2read.c (new_symbol): Update.

2018-07-16Move the using directives to buildsym_compunitTom Tromey1-12/+41
This moves the globals local_using_directives and global_using_directives to be members of buildsym_compunit, and adds the necessary accessors. gdb/ChangeLog 2018-07-16 Tom Tromey <tom@tromey.com> * dwarf2read.c (using_directives, read_func_scope) (read_lexical_block_scope): Update. * cp-namespace.c (cp_scan_for_anonymous_namespaces): Update. * buildsym.h (local_using_directives, global_using_directives): Don't declare.

(get_local_using_directives, set_local_using_directives) (get_global_using_directives): New functions. (buildsym_init): Update.
2018-07-16Make free_pending_blocks staticTom Tromey1-2/+9
free_pending_blocks can be static because scoped_free_pendings (et al) arrange for it to be NULL in the "steady state". This removes a couple of unnecessary calls to free_pending_blocks and changes it to be static. gdb/ChangeLog 2018-07-16 Tom Tromey <tom@tromey.com> * xcoffread.c (xcoff_initial_scan): Don't call free_pending_blocks. * dbxread.c (dbx_symfile_read): Don't call free_pending_blocks. * buildsym.h (class scoped_free_pendings): Add constructor. (free_pending_blocks): Don't declare. * buildsym.c (scoped_free_pendings::scoped_free_pendings): New. (free_pending_blocks): Now static.
2018-07-16Move the subfile stack to buildsym_compunitTom Tromey1-26/+13
This moves the global subfile_stack to be a member of buildsym_compunit. It also change this to be a std::vector, which simplifies the code. gdb/ChangeLog 2018-07-16 Tom Tromey <tom@tromey.com> * buildsym.h (push_subfile, pop_subfile): Update declarations. * buildsym.c (struct buildsym_compunit) <m_subfile_stack>: New member. (struct subfile_stack): Remove. (subfile_stack): Remove. (push_subfile, pop_subfile, buildsym_init): Update.
2018-07-16Use gdb_assert in two places in buildsym.cTom Tromey1-10/+2
This changes buildsym.c to use gdb_assert rather than internal_error in a couple of spots. gdb/ChangeLog 2018-07-16 Tom Tromey <tom@tromey.com> * buildsym.c (push_subfile): Use gdb_assert. (pop_subfile): Use gdb_assert.
2018-07-16Remove merge_symbol_listsTom Tromey1-27/+0
I discovered that merge_symbol_lists is unused, so this removes it. gdb/ChangeLog 2018-07-16 Tom Tromey <tom@tromey.com> * buildsym.h (merge_symbol_lists): Remove. * buildsym.c (merge_symbol_lists): Remove.
2018-07-16Remove buildsym_new_initTom Tromey1-11/+1
buildsym_new_init is just an alias for buildsym_init. This removes it. In the long run buildsym_init will also go away; this patch just helps make things a bit clearer in the meantime. gdb/ChangeLog 2018-07-16 Tom Tromey <tom@tromey.com> * xcoffread.c (xcoff_new_init): Update. * mipsread.c (mipscoff_new_init): Update. * mdebugread.c (mdebug_build_psymtabs): Update. * elfread.c (elf_new_init): Update. * dbxread.c (dbx_new_init, coffstab_build_psymtabs) (elfstab_build_psymtabs, stabsect_build_psymtabs): Update. * buildsym.h (buildsym_new_init): Don't declare. * buildsym.c (buildsym_new_init): Remove.
2018-07-16Move within_function to stabsreadTom Tromey1-1/+0
The global within_function is only used by a few symbol readers. This patch moves the global out of buildsym and into stabsread, which seemed like a better fit. It also arranges for the existing readers to clear the global at the appropriate time. gdb/ChangeLog 2018-07-16 Tom Tromey <tom@tromey.com> * stabsread.h (within_function): Move from buildsym.h. * stabsread.c (start_stabs): Clear within_function. * coffread.c (coff_start_symtab): Clear within_function. * buildsym.h (within_function): Move to stabsread.h. * buildsym.c (prepare_for_building): Update.
2018-07-16Move some code from buildsym to stabsreadTom Tromey1-10/+0
A few things that currently reside in buildsym.c turn out to be specific to the stabs reader. This patch moves these from buildsym.[ch] to stabsread.[ch]. gdb/ChangeLog 2018-07-16 Tom Tromey <tom@tromey.com> * stabsread.h (HASHSIZE, hashname, symnum, next_symbol_text) (next_symbol_text_func): Move from buildsym.h. * stabsread.c (hashname): Move from buildsym.c. * buildsym.h (HASHSIZE, symnum, next_symbol_text) (next_symbol_text_func, hashname): Move to stabsread.h. * buildsym.c: Don't include bcache.h (hashname): Move to stasbread.c.
2018-07-16Make context_stack_size static in buildsym.cTom Tromey1-0/+4
context_stack_size is declared in buildsym.h, but only used in buildsym.c. This makes it static in buildsym.c. gdb/ChangeLog 2018-07-16 Tom Tromey <tom@tromey.com> * buildsym.h (context_stack_size): Don't declare. * buildsym.c (context_stack_size): New global.
2018-07-16Move last_source_start_addr to buildsym_compunitTom Tromey1-12/+36
This moves the global last_source_start_addr into buildsym_compunit, adding some accessors as well. gdb/ChangeLog 2018-07-16 Tom Tromey <tom@tromey.com> * xcoffread.c (aix_process_linenos, complete_symtab): Update. * dbxread.c (read_ofile_symtab): Update. * coffread.c (coff_start_symtab, coff_end_symtab): Update. * buildsym.h (last_source_start_addr): Remove.

2018-07-16Move pending_macros to buildsym_compunitTom Tromey1-28/+27
This moves the pending_macros global into buildsym_compunit. gdb/ChangeLog 2018-07-16 Tom Tromey <tom@tromey.com> * buildsym.c (~buildsym_compunit): Free the macro table. (struct buildsym_compunit) <get_macro_table, release_macros>: New methods. <m_pending_macros>: New member. (pending_macros): Remove.

2018-07-16Add assert in prepare_for_buildingTom Tromey1-0/+1
This adds an assertion in prepare_for_building. This was useful for verifying whether some subsequent changes were valid. gdb/ChangeLog 2018-07-16 Tom Tromey <tom@tromey.com> * buildsym.c (prepare_for_building): Add assert.
2018-07-16Change buildsym_compunit::comp_dir to be a unique_xmalloc_ptrTom Tromey1-6/+5
This change buildsym_compunit::comp_dir to be a unique_xmalloc_ptr. This is just a small cleanup to remove some manual memory management. gdb/ChangeLog 2018-07-16 Tom Tromey <tom@tromey.com> * buildsym.c (~buildsym_compunit): Update. (struct buildsym_compunit) <comp_unit>: Now a unique_xmalloc_ptr. (start_subfile, patch_subfile_names) (end_symtab_with_blockvector): Update.
2018-07-16Use new and delete for buildsym_compunitTom Tromey1-50/+41
This changes buildsym_compunit to use new and delete. gdb/ChangeLog 2018-07-16 Tom Tromey <tom@tromey.com> * buildsym.c (struct buildsym_compunit): Add constructor, destructor, initializers. (start_buildsym_compunit): Remove. (free_buildsym_compunit): Use "delete". (start_symtab, restart_symtab): Use "new".
2018-05-23Remove symfile_complaintsTom Tromey1-17/+10
The complaint system seems to allow for multiple different complaint topics. However, in practice only symfile_complaints has ever been defined. Seeing that complaints.c dates to 1992, and that no new complaints have been added in the intervening years, I think it is reasonable to admit that complaints are specifically related to debuginfo reading. This patch removes symfile_complaints and updates all the callers.
