2018-08-09diagnostics: add line numbers to source (PR other/84889)David Malcolm1-0/+1
This patch adds a left margin to the lines of source (and annotations) printed by diagnostic_show_locus, so that e.g. rather than: test.c: In function 'test': test.c:12:15: error: 'struct foo' has no member named 'm_bar'; did you mean 'bar'? return ptr->m_bar; ^~~~~ bar we print: test.c: In function 'test': test.c:12:15: error: 'struct foo' has no member named 'm_bar'; did you mean 'bar'? 12 | return ptr->m_bar; | ^~~~~ | bar Similarly, for a multiline case (in C++ this time), this: bad-binary-ops.C: In function 'int test_2()': bad-binary-ops.C:26:4: error: no match for 'operator+' (operand types are 's' and 't') return (some_function () ~~~~~~~~~~~~~~~~ + some_other_function ()); ^~~~~~~~~~~~~~~~~~~~~~~~ becomes: bad-binary-ops.C: In function 'int test_2()': bad-binary-ops.C:26:4: error: no match for 'operator+' (operand types are 's' and 't') 25 | return (some_function () | ~~~~~~~~~~~~~~~~ 26 | + some_other_function ()); | ^~~~~~~~~~~~~~~~~~~~~~~~ I believe this slightly improves the readability of the output, in that it: - distinguishes between the user's source code vs the annotation lines that we're adding (the underlinings and fix-it hints here) - shows the line numbers in another place (potentially helpful for multiline diagnostics, where the user can see the line numbers directly, rather than have to figure them out relative to the caret: in the 2nd example, note how the diagnostic is reported at line 26, but the first line printed is actually line 25) I'm not sure that this is the precise format we want to go with [1], but I think it's an improvement over the status quo, and we're in stage 1 of gcc 9, so there's plenty of time to shake out issues. I've turned it on by default; it can be disabled via -fno-diagnostics-show-line-numbers (it's also turned off in the testsuite, to avoid breaking numerous existing test cases). [1] Some possible variants: - maybe just "LL|" rather than "LL | " - maybe ':' rather than '|' - maybe we should have some leading indentation, to better split up the diagnostics visually via the left-hand column - etc gcc/ChangeLog: PR other/84889 * common.opt (fdiagnostics-show-line-numbers): New option. * diagnostic-show-locus.c (class layout): Add fields "m_show_line_numbers_p" and "m_linenum_width"; (num_digits): New function.

2018-06-01DWARF5: Don't generate DW_AT_loclists_base for split compile unit DIEs.Mark Wielaard1-3/+9
The loclists_base attribute is used to point to the beginning of the loclists index of a DWARF5 loclists table when using DW_FORM_loclistsx. For split compile units the base is not given by the attribute, but is either the first (and only) index in the .debug_loclists.dwo section, or (when placed in a .dwp file) given by the DW_SECT_LOCLISTS row in the .debug_cu_index section. The loclists_base attribute is only valid for the full (or skeleton) compile unit DIE in the main (relocatable) object. But GCC only ever generates a loclists table index for the .debug_loclists section put into the split DWARF .dwo file. For split compile unit DIEs it is confusing (and not according to spec) to also have a DW_AT_loclists_base attribute (which might be wrong, since its relocatable offset won't actually be relocated). gcc/ChangeLog * dwarf2out.c (dwarf2out_finish): Remove generation of DW_AT_loclists_base.

2018-04-28DWARF: Add .debug_addr table header for dwarf_version >= 5.Mark Wielaard1-1/+24
GNU DebugFission didn't add table headers for the .debug_addr tables, but DWARF5 does. The table header makes it possible for a DWARF consumer to parse the address tables without having to index all .debug_info CUs first. We can keep using the .debug_addr section label as is, because the DW_AT_[GNU_]addr_base attribute points at the actual address index, which starts right after the table header. So the label is generated at the correct location whether the header is added first or not. Add DW_AT_addr_base instead of DW_AT_GNU_addr_base to the skeleton CU DIE for DWARF5. gcc/ChangeLog * dwarf2out.c (dwarf2out_finish): Add .debug_addr table header for dwarf_version >= 5. (dwarf_AT): Handle DW_AT_addr_base. (add_top_level_skeleton_die_attrs): Use dwarf_AT for DW_AT_addr_base. From-SVN: r259743
2018-04-25DWARF sort longer dirs before shorter ones in directory table.Mark Wielaard1-4/+7
When gcc dwarf2out generates the .debug_line table itself (for example when generating one for a split DWARF .dwo) it uses natural sorting for the directory table. Shorter directory paths come before longer directory paths with the same prefix. This causes the files in the line table to pick the shorter dir. Creating slightly ineffecient line tables because the longer directory paths will never be used. Fix this by changing file_info_cmp () to pick longer directory prefixes before shorter ones. We still sort files (the compilation unit) without any directory path before all entries with a directory path, so they will still use dir entry 0 (the working directory). A hello.c program would get the following dir and line table before: Directory table: /opt/local/install/gcc/lib/gcc/x86_64-pc-linux-gnu/8.0.1/include /usr/include /usr/include/bits File name table: Entry Dir Time Size Name 1 0 0 0 hello.c 2 1 0 0 stddef.h 3 2 0 0 bits/types.h 4 2 0 0 libio.h 5 2 0 0 stdio.h 6 2 0 0 bits/sys_errlist.h Note that the last directory table entry is never used. After this patch it looks as follows: Directory table: /opt/local/install/gcc/lib/gcc/x86_64-pc-linux-gnu/8.0.1/include /usr/include/bits /usr/include File name table: Entry Dir Time Size Name 1 0 0 0 hello.c 2 1 0 0 stddef.h 3 2 0 0 types.h 4 3 0 0 libio.h 5 3 0 0 stdio.h 6 2 0 0 sys_errlist.h Which is similar to what gas would output. gcc/ChangeLog: * dwarf2out.c (file_info_cmp): Sort longer dir prefixes before shorter ones.

2018-03-10[IEPM] [PR debug/84620] use constant form for DW_AT_GNU_entry_viewAlexandre Oliva1-6/+96
When outputting entry views in symbolic mode, we used to use a lbl_id, but that outputs the view as an addr, perhaps even in an indirect one, which is all excessive and undesirable for a small assembler-computed constant. Introduce a new value class for symbolic views, so that we can output the labels as constant data, using as narrow forms as possible, but wide enough for any symbolic views output in the compilation. We don't know exactly where the assembler will reset views, but we count the symbolic views since known reset points and use that as an upper bound for view numbers. Ideally, we'd use uleb128, but then the compiler would have to defer .debug_info offset computation to the assembler. I'm not going there for now, so a symbolic uleb128 assembler constant in an attribute is not something GCC can deal with ATM. for gcc/ChangeLog PR debug/84620 * dwarf2out.h (dw_val_class): Add dw_val_class_symview.

2018-03-08[LVU] reset view at function entry, omit views at line zeroAlexandre Oliva1-20/+69
Location views might be associated with locations that lack line number information (line number zero), but since we omit .loc directives that would have been issued with line number zero, we also omit the symbolic view numbers that would have been issued at such points. Resetting views at function entry points address some of these issues, and alleviate the huge chains of symbolic views that have burdened assemblers since we disabled -ginternal-reset-location-views by default, but other problems of undefined views remain when it's not the whole function that lacks line number info, just parts of it. So, when we encounter a request to output a view that may have been referenced, but we decide to omit the .loc because the line is zero, we will now omit the view as well, i.e., we will internally regard that view as zero-numbered. for gcc/ChangeLog PR debug/84404 PR debug/84408 * dwarf2out.c (struct dw_line_info_table): Update comments for view == -1.

2018-02-09[LVU] Introduce location viewsAlexandre Oliva1-68/+632
This patch introduces an option to enable the generation of location views along with location lists. The exact format depends on the DWARF version: it can be a separate attribute (DW_AT_GNU_locviews) or (DW_LLE_view_pair) entries in DWARF5+ loclists. Line number tables are also affected. If the assembler is found, at compiler build time, to support .loc views, we use them and assembler-computed view labels, otherwise we output compiler-generated line number programs with conservatively-computed view labels. In either case, we output view information next to line number changes when verbose assembly output is requested. This patch requires an LVU patch that modifies the exported API of final_scan_insn. It also expects the entire SFN patchset to be installed first, although SFN is not a requirement for LVU. for include/ChangeLog * dwarf2.def (DW_AT_GNU_locviews): New. * dwarf2.h (enum dwarf_location_list_entry_type): Add DW_LLE_GNU_view_pair.
