Chris Bieneman 6d8e5c9685 [NFC] Make file offsets a regex to handle CRLF
None of these tests are really intended to test the file offset as much
as to test the structure. Making the regex allows this test to work
even if the file is checked out with CRLF line endings.

Nikita Popov 8043beb890 [JSONNodeDumper] Do not print mangled names for local variables (PR49111)
Mangled names are not meaningful for variables with local storage,
and may not be well defined (getting the mangled name for VLA
crashes the mangler). As such, do not include them in the JSON
dump.

This allows running update_cc_test_checks on some OpenMP tests again.

Fixes https://github.com/llvm/llvm-project/issues/49111.

Nikita Popov da007a33c9 [JSONNodeDumper] Regenerate test checks (NFC)
gen_ast_dump_json_test.py adds these lines of whitespace. Precommit
it to avoid spurious diffs in future changes.

David Blaikie aee4925507 Recommit: Compress formatting of array type names (int [4] -> int[4])
Based on post-commit review discussion on
2bd8493847 with Richard Smith.

Other uses of forcing HasEmptyPlaceHolder to false seem OK to me -
they're all around pointer/reference types where the pointer/reference
token will appear at the rightmost side of the left side of the type
name, so they make nested types (eg: the "int" in "int *") behave as
though there is a non-empty placeholder (because the "*" is essentially
the placeholder as far as the "int" is concerned).

This was originally committed in 277623f4d5

Reverted in f9ad1d1c77 due to breakages
outside of clang - lldb seems to have some strange/strong dependence on
"char [N]" versus "char[N]" when printing strings (not due to that name
appearing in DWARF, but probably due to using clang to stringify type
names) that'll need to be addressed, plus a few other odds and ends in
other subprojects (clang-tools-extra, compiler-rt, etc).

David Blaikie f9ad1d1c77 Revert "Compress formatting of array type names (int [4] -> int[4])"
Looks like lldb has some issues with this - somehow it causes lldb to
treat a "char[N]" type as an array of chars (prints them out
individually) but a "char [N]" is printed as a string. (even though the
DWARF doesn't have this string in it - it's something to do with the
string lldb generates for itself using clang)

This reverts commit 277623f4d5.

william woodruff 451d0596d7 [clang] Fix JSON AST output when a filter is used
Without this, the combination of `-ast-dump=json` and `-ast-dump-filter FILTER` produces invalid JSON: the first line is a string that says `Dumping $SOME_DECL_NAME: `.

Matheus Izvekov aef5d8fdc7 [clang] NFC: Rename rvalue to prvalue
This renames the expression value categories from rvalue to prvalue,
keeping nomenclature consistent with C++11 onwards.

C++ has the most complicated taxonomy here, and every other language
only uses a subset of it, so it's less confusing to use the C++ names
consistently, and mentally remap to the C names when working on that
context (prvalue -> rvalue, no xvalues, etc).

Renames:
* VK_RValue -> VK_PRValue
* Expr::isRValue -> Expr::isPRValue
* SK_QualificationConversionRValue -> SK_QualificationConversionPRValue
* JSON AST Dumper Expression nodes value category: "rvalue" -> "prvalue"

Alex Richardson 3c3048c18b Include the mangled name in -ast-dump=json
I am planning to use this feature to make update_cc_test_checks.py less fragile
by obtaining the mangled names directly from -ast-dump=json. Currently,
it uses c-index-test which ignores the -triple=, etc. arguments that are
in the RUN: line and therefore does not generate checks for some targets.

The AST dump tests were updated using the following command:
`python $LLVM_BINDIR/gen_ast_dump_json_test.py --update --source $LLVM_SRC/clang/test/AST/*-json.*`

Aaron Ballman 27c7a9b157 Add more information to JSON AST dumping of source locations.
This adds information about the offset within the source file to the given source location as well as information about the include file a location is from. These pieces of information allow for more efficient post-processing of JSON AST dumps.

Aaron Ballman 4d08f899e3 Dump floating-point values as strings when dumping to JSON.
This fixes a bug where we would have an invalid JSON attribute (e.g., "value": inf). It also increases the precision of the values because they're not represented as approximate doubles with the host architecture's floating-point model.

Aaron Ballman a612e34c14 Augment location information when dumping the AST to JSON.
Rather than create JSON objects for source locations and ranges, we instead stream them out directly. This allows us to elide duplicate information (without JSON field reordering causing an issue) like file names and line numbers, similar to the text dump. This also adds token length information when dumping the source location.
