* [analyzer] Add annotation attribute to trust retain count implementationDevin Coughlin2017-07-192-5/+86
| | | | | | | | | | | | | | | | | Add support to the retain-count checker for an annotation indicating that a function's implementation should be trusted by the retain count checker. Functions with these attributes will not be inlined and the arguments will be treating as escaping. Adding this annotation avoids spurious diagnostics when the implementation of a reference counting operation is visible but the analyzer can't reason precisely about the ref count.

* [scan-build-py] Patch to fix "-analyzer-config" optionPetr Hosek2017-07-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | I noticed that when I use "-analyze-config" option in scan-build-py, it behaves differently from original perl based scan-build. For example, command: $ scan-build -analyzer-config ipa=basic-inlining make Will work without any issues on perl version of scan-build. But on scan-build-py it will throw an error message "error reading 'ipa=basic-inlining'". After debugging, it turns out that the scan-build-py does not put "-analyzer-config" flag in front of the analyzer config flags (in this case is the "ipa=basic-inlining") in the final clang command line. This patch fixes this issue.

* clang-format: [JS] Correctly format JavaScript imports with long module pathsMartin Probst2017-07-183-1/+29
| | | | | | | | | | | | | | | | | | | | | | | Currently the `UnwrappedLineParser` fails to correctly unwrap JavaScript imports where the module path is not on the same line as the `from` keyword. For example: import {A} from 'some/path/longer/than/column/limit/module.js';``` This causes issues when in the middle a list of imports because the formatter thinks it has reached the end of the imports, and therefore will not sort any imports lower in the list. The formatter will, however, split the `from` keyword and the module path if the path exceeds the column limit, which triggers the issue the next time the file is formatted.

* [Basic] Detect Git submodule version in CMakeBrian Gesiak2017-07-171-1/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: When searching for Git version control information, libBasic's CMake checks for the path '.git/logs/HEAD'. However, when LLVM is included as a Git submodule, this path does not exist. Instead, it contains a '.git' file with the following: ``` gitdir: ../../.git/modules/external/llvm ``` Where '../..' is the relative path to the root repository that contains the LLVM Git submodule. Because of this discrepancy, `clang --version` does not output source control information if built from a Git submodule. To fix, check whether '.git' is a directory or a file. If it's a directory, simply use the '.git/logs/HEAD' path. If it's a file, read it and check for the tell-tale sign of a Git submodule: the text "gitdir:". If it exists, follow that path and use the 'logs/HEAD' at that location instead. This allows not only the correct revision information to be retrieved, but also uses a file that will change with each source control revision. Test Plan: 1. Before applying this change, build Clang as a Git submodule in a repository that places it in external/clang, and confirm no revision information is output when `clang --version` is invoked (just "clang 5.0.0" is output, no Git hashes). 2. Apply these changes and build Clang as a Git repository nested under llvm/tools/clang, and confirm that `clang --version` displays correct version information. 3. Apply these changes and build Clang as a Git submodule using the structure described in (1), and confirm version control information is output as in (2).
