Xiangling Liao 6ef801aa6b [AIX] Static init frontend recovery and backend support
On the frontend side, this patch recovers AIX static init implementation to
use the linkage type and function names Clang chooses for sinit related function.

On the backend side, this patch sets correct linkage and function names on aliases
created for sinit/sterm functions.

Eduardo Caldas 8abb5fb68f [SyntaxTree] Use simplified grammar rule for `NestedNameSpecifier` grammar nodes
This is our grammar rule for nested-name-specifiers:
globalbal-specifier:
  /*empty*/
simple-template-specifier:
  template_opt simple-template-id
name-specifier:
  global-specifier
  decltype-specifier
  identifier
  simple-template-specifier
nested-name-specifier:
  list(name-specifier, ::, non-empty, terminated)

It is a relaxed version of C++ [expr.prim.id] and quite simpler to map to our API.

TODO: refine name specifiers, `simple-template-name-specifier` and
decltype-name-specifier` are token soup for now.

Mitchell Balan 7ad60f6452 [clang-format] fix BreakBeforeBraces.MultiLine with for each macros
Summary:
The MultiLine option in BreakBeforeBraces was only handling standard
control statement, leading to invalid indentation with for each macros:

Previous behavior:

/* invalid: brace should be on the same line */
Q_FOREACH(int a; list)
{
    foo();
}

/* valid */
Q_FOREACH(int longVariable;
          list)
{
    foo();
}

To fix this, simply add the TT_ForEachMacro kind in the list of
recognized control statements for the multiline option.

This is a fix for https://bugs.llvm.org/show_bug.cgi?id=44632

[clang] Add -fno-delayed-template-parsing to the added unit tests in DeclPrinterTest.cpp 2020-08-05 14:13:05 +01:00
Bruno Ricci f7a039de7a
[clang][NFC] DeclPrinter: use NamedDecl::getDeclName instead of NamedDecl::printName to print the name of enumerations, namespaces and template parameters.
NamedDecl::printName will print the pretty-printed name of the entity, which
is not what we want here (we should print "enum { e };" instead of "enum
(unnamed enum at input.cc:1:5) { e };").

For now only DecompositionDecl and MDGuidDecl have an overloaded printName so
this does not result in any functional change, but this change is needed since
I will be adding overloads to better handle unnamed entities in diagnostics.

[clang][Tooling] Fix addTargetAndModeForProgramName to use correct flag names
The logic was using incorrect flag versions. For example:
- `-target=` can't be a prefix, it must be `--target=`.
- `--driver-mode` can't appear on its own, value must be attached to it.

While fixing those, also changes the append logic to make use of new
`--target=X` format instead of the legacy `-target X` version.

In addition to that makes use of the OPTTable instead of hardcoded strings to
make sure helper also gets updated if clang's options are modified.

Logan Smith a52aea0ba6 Use INTERFACE_COMPILE_OPTIONS to disable -Wsuggest-override for any target that links to gtest
This cleans up several CMakeLists.txt's where -Wno-suggest-override was manually specified. These test targets now inherit this flag from the gtest target.

Some unittests CMakeLists.txt's, in particular Flang and LLDB, are not touched by this patch. Flang manually adds the gtest sources itself in some configurations, rather than linking to LLVM's gtest target, so this fix would be insufficient to cover those cases. Similarly, LLDB has subdirectories that manually add the gtest headers to their include path without linking to the gtest target, so those subdirectories still need -Wno-suggest-override to be manually specified to compile without warnings.

Logan Smith 77e0e9e17d Reapply "Try enabling -Wsuggest-override again, using add_compile_options instead of add_compile_definitions for disabling it in unittests/ directories."
add_compile_options is more sensitive to its location in the file than add_definitions--it only takes effect for sources that are added after it. This updated patch ensures that the add_compile_options is done before adding any source files that depend on it.

Using add_definitions caused the flag to be passed to rc.exe on Windows and thus broke Windows builds.

Summary:

This is very expensive operation with a lot of `llvm::sys::fs::equivalent()` calls in some cases.

This patch disables file symlinks for performance reasons.

Example scenario without this patch:
- compile_commands.json generated at clangd build (contains ~3000 files).
- it tooks more than 1 second to get compile command for newly created file in the root folder of LLVM project.
- we wait for 1 second every time when clangd requests compile command for this file (at file change).

Dmitry Polukhin 9e7fddbd36 [yaml][clang-tidy] Fix multiline YAML serialization
Summary:
New line duplication logic introduced in https://reviews.llvm.org/D63482
has two issues: (1) there is no logic that removes duplicate newlines
when clang-apply-replacment reads YAML and (2) in general such logic
should be applied to all strings and should happen on string
serialization level instead in YAML parser.

This diff changes multiline strings quotation from single quote `'` to
double `"`. It solves problems with internal newlines because now they are
escaped. Also double quotation solves the problem with leading whitespace after
newline. In case of single quotation YAML parsers should remove leading
whitespace according to specification. In case of double quotation these
leading are internal space and they are preserved. There is no way to
instruct YAML parsers to preserve leading whitespaces after newline so
double quotation is the only viable option that solves all problems at
once.
