◆ location_hash
| #define location_hash int_hash<location_t, UNKNOWN_LOCATION, BUILTINS_LOCATION> |
Hasher for 'location_t' values satisfying '!RESERVED_LOCATION_P', thus able to use 'UNKNOWN_LOCATION'/'BUILTINS_LOCATION' as spare values for 'Empty'/'Deleted'.
Per PR103157 "'gengtype': 'typedef' causing infinite-recursion code to be
generated", don't use
typedef int_hash<location_t, UNKNOWN_LOCATION, BUILTINS_LOCATION>
location_hash;
here.
It works for a single-use case, but when using a 'struct'-based variant
struct location_hash
: int_hash<location_t, UNKNOWN_LOCATION, BUILTINS_LOCATION> {};
in more than one place, 'gengtype' generates duplicate functions (thus:
"error: redefinition of 'void gt_ggc_mx(location_hash&)'" etc.).
Attempting to mark that one up with GTY options, we run into a 'gengtype'
"parse error: expected '{', have '<'", which probably falls into category
"understanding of C++ is limited", as documented in 'gcc/doc/gty.texi'.
Thus, use a plain ol' '#define':

◆ expand_location_to_spelling_point()

extern |
Expand the source location LOC into a human readable location. If LOC is virtual, it resolves to the expansion location of the relevant macro. If LOC resolves to a builtin location, the file name of the readable location is set to the string "<built-in>".

◆ expansion_point_location()
|
extern |
If LOCATION is a virtual location for a token coming from the expansion of a macro, unwind to the location of the expansion point of the macro.
References ggc_alloc(), line_table, and NULL.
◆ expansion_point_location_if_in_system_header()
|
extern |
If LOCATION is in a system header and if it is a virtual location for a token coming from the expansion of a macro, unwind it to the location of the expansion point of the macro. If the expansion point is also in a system header return the original LOCATION. Otherwise, return the location of the expansion point. This is used for instance when we want to emit diagnostics about a token that may be located in a macro that is itself defined in a system header, for example, for the NULL macro. In such a case, if LOCATION were passed directly to diagnostic functions such as warning_at, the diagnostic would be suppressed (unless -Wsystem-headers).

Referenced by pass_walloca::execute(), gimple_or_expr_nonartificial_location(), gimplify_va_arg_expr(), set_inlining_locations(), tree_inlined_location(), and warn_string_no_nul().
◆ from_macro_definition_at()
|
inline |
Return true if LOCATION is the locus of a token that comes from a macro definition, false otherwise. This differs from from_macro_expansion_at in its treatment of macro arguments, for which this returns false.
References ggc_alloc(), and line_table.
◆ from_macro_expansion_at()
|
inline |
Return true if LOCATION is the locus of a token that comes from a macro expansion, false otherwise.
References ggc_alloc(), and line_table.
◆ get_discriminator_from_loc()

Return the discriminator for LOCUS.
References get_discriminator_from_loc(), and line_table.
Referenced by compute_discriminator(), dump_location(), autofdo::get_combined_location(), get_discriminator_from_loc(), has_discriminator(), lto_output_location_1(), and set_block().

◆ get_source_text_between()
|
extern |
Return a NUL-terminated copy of the source text between two locations, or NULL if the arguments are invalid. The caller is responsible for freeing the return value.
References end(), expand_location_to_spelling_point(), char_span::get_buffer(), ggc_alloc(), char_span::length(), NULL, obstack, char_span::subspan(), and char_span::xstrdup().

◆ has_discriminator()
|
extern |
Return TRUE if LOCUS represents a location with a discriminator.
References get_discriminator_from_loc().
Referenced by assign_discriminators().
◆ in_system_header_at()
|
inline |
Return a positive value if LOCATION is the locus of a token that is located in a system header, O otherwise. It returns 1 if LOCATION is the locus of a token that is located in a system header, and 2 if LOCATION is the locus of a token located in a C system header that therefore needs to be extern "C" protected in C++. Note that this function returns 1 if LOCATION belongs to a token that is part of a macro replacement-list defined in a system header, but expanded in a non-system file.
References ggc_alloc(), and line_table.
Referenced by expansion_point_location_if_in_system_header(), diagnostic_context::get_any_inlining_info(), and set_inlining_locations().
◆ is_location_from_builtin_token()
|
extern |
Test if the location originates from the spelling location of a builtin-tokens. That is, return TRUE if LOC is a (possibly virtual) location of a built-in token that appears in the expansion list of a macro. Please note that this function also works on tokens that result from built-in tokens. For instance, the function would return true if passed a token "4" that is the result of the expansion of the built-in __LINE__ macro.
References BUILTINS_LOCATION, ggc_alloc(), line_table, map, and NULL.
◆ location_compute_display_column()
|
extern |
An expanded_location stores the column in byte units. This function converts that column to display units. That requires reading the associated source line in order to calculate the display width. If that cannot be done for any reason, then returns the byte column as a fallback.

Referenced by lto_location_cache::apply_location_cache(), assign_discriminator(), and assign_discriminators().
◆ make_location() [1/2]
|
extern |
Construct a location with caret at CARET, ranging from START to
FINISH.
For example, consider:
11111111112
12345678901234567890
522
523 return foo + bar;
~~~~^~~~~
524
The location's caret is at the "+", line 523 column 15, but starts
earlier, at the "f" of "foo" at column 11. The finish is at the "r"
of "bar" at column 19.

◆ make_location() [2/2]
|
extern |
Same as above, but taking a source range rather than two locations.

◆ special_fname_builtin()
Returns the translated string referring to the special location.

Referenced by expand_location_1(), and diagnostic_context::get_location_text().
◆ STATIC_ASSERT()
| STATIC_ASSERT | ( | ) |
line-map.cc reserves RESERVED_LOCATION_COUNT to the user. Ensure both UNKNOWN_LOCATION and BUILTINS_LOCATION fit into that.
