This patch renames the "error" callback within libcpp
to "diagnostic", and uses the pair of enums in cpplib.h, rather
than passing two different kinds of "int" around.

(c_option_controlling_cpp_diagnostic): ...this, and convert
"reason" from int to enum.

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>
74 | #endif

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:

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).

This commit adds the -fmacro-prefix-map option that allows remapping of file
names in __FILE__, __BASE_FILE__, and __builtin_FILE(), similar to how
-fdebug-prefix-map allows to do the same for debug information.
Additionally, it adds -ffile-prefix-map which can be used to specify both
mappings with a single option (and, should we need to add more -f*-prefix-map
options in the future, those as well).
