Fix ICE with #line directive (PR c/89410)
PR c/89410 reports various issues with #line directives with very large numbers; one of them is an ICE inside diagnostic-show-locus.c when emitting a diagnostic at line 0xffffffff. The issue is that the arithmetic in layout::calculate_line_spans to determine if two line spans are sufficiently close to consolidate was using the unsigned 32-bit linenum_type, which was overflowing when comparing the line for the expanded location with those of the location range (all on line 0xffffffff), leading to it erroneously adding two spans for the same line, leading to an assertion failure. This patch fixes the ICE by generalizing the use of long long in line-map.h's comparison function for linenum_type into a new linenum_arith_t typedef, and using it here. Doing so uncovered a second problem: the loop to print the lines within the line_span for this case is infinite: looping from 0xfffffff upwards, overflowing to 0, and then never becoming greater than 0xfffffff. The patch fixes this by using linenum_arith_t there also. gcc/ChangeLog: PR c/89410 * diagnostic-show-locus.c (layout::calculate_line_spans): Use linenum_arith_t when determining if two adjacent line spans are close enough to merge.

Less verbose fix-it hints for missing header files (PR 87091)
This patch tweaks maybe_add_include_fixit so that if we're emitting a note
about adding the header file, the note's primary location will be replaced
by that of the fix-it hint, to avoid repeating a location we've already
emitted (or one close to it).
For example, this simplifies:
../x86_64-pc-linux-gnu/libstdc++-v3/include/vector:87:27: error: msg 1
87 | using vector = std::vector<_Tp, polymorphic_allocator<_Tp>>;
| ^~~~~~
../x86_64-pc-linux-gnu/libstdc++-v3/include/vector:87:22: note: msg 2
73 | # include <debug/vector>
+++ |+#include <vector>
74 | #endif
....
87 | using vector = std::vector<_Tp, polymorphic_allocator<_Tp>>;
| ^~~
to:
../x86_64-pc-linux-gnu/libstdc++-v3/include/vector:87:27: error: msg 1
87 | using vector = std::vector<_Tp, polymorphic_allocator<_Tp>>;
| ^~~~~~
../x86_64-pc-linux-gnu/libstdc++-v3/include/vector:74:1: note: msg 2
73 | # include <debug/vector>
+++ |+#include <vector>
74 | #endif
eliminating the repetition of line 87 in the note.
Doing so requires converting show_caret_p to a tri-state, to avoid
meaninglessly printing a caret for the first column in the next line
(and colorizing it):
../x86_64-pc-linux-gnu/libstdc++-v3/include/vector:74:1: note: msg 2
73 | # include <debug/vector>
+++ |+#include <vector>

diagnostics: add labeling of source ranges
This patch adds the ability to label source ranges within a rich_location,
to be printed by diagnostic_show_locus.
For example:
pr69554-1.c:11:18: error: invalid operands to binary + (have 'const char *' and 'const char *')
11 | return (p + 1) + (q + 1);
| ~~~~~~~ ^ ~~~~~~~
| | |
| | const char *
| const char *
The patch implements labels for various type mismatch errors in the C and
C++ frontends, and in -Wformat. I implemented it wherever accurate location
information was guaranteed (there are other places that could benefit, but
we need better location information in those places).
The labels can be disabled via -fno-diagnostics-show-labels.
Similarly:
param-type-mismatch.C: In function 'int test_1(int, int, float)':
param-type-mismatch.C:11:27: error: invalid conversion from 'int' to 'const char*' [-fpermissive]
11 | return callee_1 (first, second, third);
| ^~~~~~
| |
| int
param-type-mismatch.C:7:43: note: initializing argument 2 of 'int callee_1(int, const char*, float)'
7 | extern int callee_1 (int one, const char *two, float three);
| ~~~~~~~~~~~~^~~
where the first "error" describing the bad argument gets a label
describing the type inline (since it's non-obvious from "second").
The "note" describing the type of the param of the callee *doesn't*
get a label, since that information is explicit there in the
source ("const char *two").
The idea is that in any diagnostic where two aspects of the source aren't
in sync it ought to be easier for the user if we directly show them the
mismatching aspects inline (e.g. types).
As well as type mismatch errors, perhaps labels could also be used for
buffer overflow warnings, for describing the capacity of the destination
buffer vs the size of what's being written:
sprintf (buf, "filename: %s\n", file);
^~~ ~~~~~~~~~~~^~~
| |
capacity: 32 10 + strlen(file) + 2
or somesuch. Another idea might be for macro expansion warnings:
warning: repeated side effects in macro expansion...
x = MIN (p++, q++);
~~~~^~~~~~~~~~
note: ...expanded here as
#define MIN(X,Y) (X<Y?X:Y)
^~~ ~ ~ ~ ~ ~ ~
| | | | | |
| | | | | q++
| | | | p++
| | | q++
| q++ p++
p++
The patch removes some logic from multiline.exp which special-cased
lines ending with a '|' character (thus complicating testing of this
patch). I believe that this was a vestige from experiments I did to
support strippng dg directives from the output; it was present in the
earliest version of multiline.exp I posted:

Fix ICE for missing header fix-it hints with overlarge #line directives (PR c/84852)
PR c/84852 reports an ICE inside diagnostic_show_locus when printing
a diagnostic for a source file with a #line >= 2^31:
#line 7777777777
int foo (void) { return strlen(""); }
where we're attempting to print a fix-it hint at the top of the file
and underline the "strlen" (two "line spans").
The
#line 7777777777
won't fix within the 32-bit linenum_type, and is truncated from
0x1cf977871
to
0xcf977871
i.e. 3482810481 in decimal.
Such a #line is reported by -pedantic and -pedantic-errors, but we
shouldn't ICE.
The ICE is an assertion failure within layout::calculate_line_spans,
where the line spans have not been properly sorted.
The layout_ranges are stored as int, rather than linenum_type,
giving line -812156815 for the error, and line 1 for the fix-it hint.
However, line_span uses linenum_type rather than int.
line_span::comparator compares these values as int, and hence
decides that (linenum_type)3482810481 aka (int)-812156815 is less
than line 1.
This leads to this assertion failing in layout::calculate_line_spans:
1105 gcc_assert (next->m_first_line >= current->m_first_line);
since it isn't the case that 1 >= 3482810481.
The underlying problem is the mix of types for storing line numbers:
in parts of libcpp and diagnostic-show-locus.c we use linenum_type;
in other places (including libcpp's expanded_location) we use int.
I looked at using linenum_type throughout, but doing so turned into
a large patch, so this patch fixes the ICE in a less invasive way
by merely using linenum_type more consistently just within
diagnostic-show-locus.c, and fixing line_span::comparator to properly
handle line numbers (and line number differences) >= 2^31, by using
a new helper function for linenum_type differences, computing the
difference using long long, and using the sign of the difference
(as the difference might not fit in the "int" return type imposed
by qsort).

Reject fix-it hints for various awkward boundary cases (PR c/82050)
PR c/82050 reports a failed assertion deep within diagnostic_show_locus's code for printing fix-it hints. The root cause is a fix-it hint suggesting a textual replacement, where the affected column numbers straddle the LINE_MAP_MAX_COLUMN_NUMBER boundary, so that the start of the range has a column number, but the end of the range doesn't. The fix is to verify that the column numbers are sane when adding fix-it hints to a rich_location, rejecting fix-it hints where they are not. libcpp/ChangeLog: PR c/82050 * include/line-map.h (LINE_MAP_MAX_COLUMN_NUMBER): Move here. * line-map.c (LINE_MAP_MAX_COLUMN_NUMBER): ...from here.

Support fix-it hints that add new lines
Previously fix-it hints couldn't contain newlines. This is
due to the need to print something user-readable for them
within diagnostic-show-locus, and for handling them within
edit-context for printing diffs and regenerating content.
This patch enables limited support for fix-it hints with newlines,
for suggesting adding new lines.
Such a fix-it hint must have exactly one newline character, at the
end of the content. It must be an insertion at the beginning of
a line (so that e.g. fix-its that split a pre-existing line are
still rejected).
They are printed by diagnostic-show-locus with a '+' in the
left-hand margin, like this:
test.c:42:4: note: suggest adding 'break;' here
+ break;
case 'b':
^~~~~~~~~
and the printer injects "spans" if the insertion location is not
near the primary range of the diagnostic e.g.:
test.c:4:2: note: unrecognized 'putchar'; suggest including '<stdio.h>'
test.c:1:1:
+#include <stdio.h>
test.c:4:2:
putchar (ch);
^~~~~~~

Eliminate fixit_hint class hierarchy
The original implementation of fix-it hints (r230674) had an abstract base class "fixit_hint" and three subclasses, representing each of insertions, replacements, and deletions. Having multiple classes for fix-it hints was a nuisance, as it required per-class logic everywhere that the hints were handled. In r239632 I eliminated the deletion subclass in favor of replacement with the empty string (two subclasses are easier than three). This patch eliminates the class hierarchy altogether by implementing insertion in terms of replacement, by representing replacements via a half-open interval (so that for an insertion, start == next location, and we're effectively replacing an empty range at the insertion point with the new string). This greatly simplifies the code for handling fix-it hints; for example it allows removal of a parallel class hierarchy of line_event within edit-context.c. It also improves consolidation of hints: we can now consolidate insertions at the same location, affecting a couple of tests (selftest::test_one_liner_many_fixits and gcc.dg/Wmissing-braces-fixits.c). gcc/ChangeLog: * diagnostic-show-locus.c (layout::get_expanded_location): Rewrite to use new fixit_hint representation, using the "replace" logic.

Implement ~line_maps ()
line_maps instances such as the global line_table are GC-managed, but the htab within location_adhoc_data_map.htab is not GC-managed. Previously this was deleted manually by a call to location_adhoc_data_fini within toplev::main. However, on adding a call to forcibly_ggc_collect after the selftests, all of the htabs for the various line_tables created during the selftests start showing up as leaks in "make selftest-valgrind", e.g.: 13,536 (1,344 direct, 12,192 indirect) bytes in 12 blocks are definitely lost in loss record 1,065 of 1,086 at 0x4A081D4: calloc (in /usr/lib64/valgrind/vgpreload_memcheck-amd64-linux.so) by 0x16DB3B0: xcalloc (xmalloc.c:163) by 0x16D8D34: htab_create_typed_alloc (hashtab.c:358) by 0x16D8DBD: htab_create_alloc (hashtab.c:286) by 0x16A2CCC: linemap_init(line_maps*, unsigned int) (line-map.c:353) by 0x1685605: selftest::line_table_test::line_table_test(selftest::line_table_case const&) (input.c:1624) by 0x167D09C: selftest::test_applying_fixits_modernize_named_init(selftest::line_table_case const&) (edit-context.c:1430) by 0x1686827: selftest::for_each_line_table_case(void (*)(selftest::line_table_case const&)) (input.c:3227) by 0x167F067: selftest::edit_context_c_tests() (edit-context.c:1658) by 0x1616E67: selftest::run_tests() (selftest-run-tests.c:71) by 0xC0DB25: toplev::run_self_tests() (toplev.c:2076) by 0x618EB4: toplev::main(int, char**) (toplev.c:2153) This patch removes the manual one-time cleanup in favor of adding a destructor to class line_maps, which cleans up the non-GC-managed htab.

fix-it hints: insert_before vs insert_after
The API for adding "insert text" fix-it hints was unclear about exactly where the text should be inserted relative to the given insertion point. This patch clarifies things by renaming the pertinent methods from richloc.add_fixit_insert to richloc.add_fixit_insert_before and adding: richloc.add_fixit_insert_after The latter allows us to consolidate some failure-handling into class rich_location, rather than having to have every such diagnostic check for it.

diagnostic-show-locus.c: handle fixits on lines outside the regular ranges
The diagnostic_show_locus implementation determines the set of line spans that need printing based on the ranges within the rich_location (in layout::calculate_line_spans). Currently this doesn't take into account fix-it hints, and hence we fail to print fix-it hints that are on lines outside of those ranges. This patch updates the implementation to take fix-it hints into account when calculating the pertinent line spans, so that such fix-it hints do get printed. It also adds some validation, to ensure that we don't attempt to print fix-its hints affecting a different source file. gcc/ChangeLog: * diagnostic-show-locus.c (class layout): Add field m_fixit_hints.

Remove arbitrary limits from rich_location
This patch eliminates the hard-coded limits within rich_location (up to 3 ranges, up to 2 fixits). The common case is still handled by embedding the values inside rich_location - it only uses dynamic allocation if these limits are exceeded, so creation of rich_location instances on the stack should still be fast.

rich_location: add convenience overloads for adding fix-it hints
Adding a fix-it hint to a diagnostic usually follows one of these patterns: (a) an insertion fix-its, with the insertion at the primary caret location (b) a removals/replacements, affecting the range of the primary location (other cases are possible, e.g. multiple fix-its, and affecting other locations, but these are the common ones) Given these common cases, this patch adds overloads of the rich_location methods for adding fix-it hints, so that the location information can be omitted if it matches that of the primary location within the rich_location. Similarly when adding "remove" and "replace" fix-it hints to a diagnostic, it's tedious to have to extract the source_range from a location_t (aka source_location). To make this more convenient, this patch adds overload of the rich_location::add_fixit_remove/replace methods, accepting a source_location directly. The patch updates the various in-tree users of fix-it hints to use the new simpler API where appropriate. I didn't touch the case where there are multiple fix-its in one rich_location, as it seems better to be more explicit about locations for this case (adding a pair of parens in warn_logical_not_parentheses). The above makes the gcc_rich_location::add_fixit_misspelled_id overload taking a const char * rather redundant, so I eliminated it. gcc/c/ChangeLog: * c-decl.c (implicit_decl_warning): Use add_fixit_replace rather than add_fixit_misspelled_id.

Allow the use of ad-hoc locations for fix-it hints
Currently the fix-it validator rejects ad-hoc locations. Fix this by calling get_pure_location on the input locations to add_fixit_insert/replace.

Add validation and consolidation of fix-it hints
The first aspect of this patch is to add some checking of fix-it hints.
The idea is to put this checking within the rich_location machinery,
rather than requiring every diagnostic to implement it for itself.
The fixits within a rich_location are "atomic": all must be valid for
any to be applicable.
We reject any fixits involving locations above
LINE_MAP_MAX_LOCATION_WITH_COLS.
There's no guarantee that it's sane to modify a macro, so we reject
any fix-its that touch them.
For example, note the attempt to provide a fix-it for the definition
of the macro FIELD:
spellcheck-fields-2.c: In function ‘test_macro’:
spellcheck-fields-2.c:26:15: error: ‘union u’ has no member named ‘colour’; did you mean ‘color’?
#define FIELD colour
^
color
spellcheck-fields-2.c:27:15: note: in expansion of macro ‘FIELD’
return ptr->FIELD;
^~~~~
After this patch, the fixit is not displayed:
spellcheck-fields-2.c: In function ‘test_macro’:
spellcheck-fields-2.c:26:15: error: ‘union u’ has no member named ‘colour’; did you mean ‘color’?
#define FIELD colour
^
spellcheck-fields-2.c:27:15: note: in expansion of macro ‘FIELD’
return ptr->FIELD;
^~~~~
We might want some way for a diagnostic to opt-in to fix-its that
affect macros, but for now it's simplest to reject them.
The other aspect of this patch is fix-it consolidation: in some cases
neighboring fix-its can be merged. For example, in a diagnostic to
modernize old-style struct initializers from:
struct s example = {
- foo: 1,
+ .foo = 1,
};
one approach would be to replace the "foo" with ".foo" and the ":"
with " =". This would give two "replace" fix-its:
foo: 1,
--- FIXIT 1
.foo
- FIXIT 2
=
This patch allows them to be consolidated into a single "replace" fix-it:
foo: 1,
----
.foo =

Reimplement removal fix-it hints in terms of replace
This patch eliminates class fixit_remove, reimplementing
rich_location::add_fixit_remove in terms of replacement with the
empty string. Deleting the removal subclass simplifies
fixit-handling code, as we only have two concrete fixit_hint
subclasses to deal with, rather than three.
The patch also fixes some problems in diagnostic-show-locus.c for
situations where a replacement fix-it has a different range to the
range of the diagnostic, by unifying the drawing of the two kinds of
fixits. For example, this:
foo = bar.field;
^
m_field
becomes:
foo = bar.field;
^

input.c: add lexing selftests and a test matrix for line_table states
This patch adds explicit testing of lexing a source file, generalizing this (and the test of ordinary line maps) over a 2-dimensional test matrix covering: (1) line_table->default_range_bits: some frontends use a non-zero value and others use zero (2) the fallback modes within line-map.c: there are various threshold values for source_location/location_t beyond line-map.c changes behavior (disabling of the range-packing optimization, disabling of column-tracking). We exercise these by starting the line_table at interesting values at or near these thresholds.

PR c++/70105: prevent nonsensical underline spew for macro expansions
diagnostic_show_locus can sometimes do the wrong thing when handling expressions built up from macros. PR c++/70105 (currently marked as a P3 regression) has an example of a diagnostic where over 500 lines of irrelevant source are printed, and underlined, giving >1000 lines of useless spew to stderr. This patch adds extra sanitization to diagnostic-show-locus.c, so that we only attempt to print underlines and secondary locations if such locations are "sufficiently sane" relative to the primary location of a diagnostic. This "sufficiently sane" condition is implemented by a new helper function compatible_locations_p, which requires such locations to have the same macro expansion hierarchy as the primary location, using linemap_macro_map_loc_unwind_toward_spelling, effectively mimicing the expansion performed by LRK_SPELLING_LOCATION. This may be too strong a condition, but it effectively fixes PR c++/70105, without removing any underlines in my testing. Successfully bootstrapped®rtested in combination with the previous patch on x86_64-pc-linux-gnu; adds 15 new PASS results to g++.sum and 4 new PASS results to gcc.sum. gcc/ChangeLog: PR c/68473 PR c++/70105 * diagnostic-show-locus.c (compatible_locations_p): New function.
