* [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.

| | | | | | | | | | | | | | | | | | | | | | | Restore the `-gz` option to the driver with some minor tweaks to handle the additional case for `-Wa,--compress-debug-sections`. This intends to make the compression of the debug information controllable from the driver. The following is the behaviour: -gz enable compression (ambiguous for format, will default to zlib-gnu) -gz=none disable compression -gz=zlib-gnu enable compression (deprecated GNU style zlib compression) -gz=zlib enable compression (zlib based compression) Although -Wa,-compress-debug-sections works, it should be discouraged when using the driver to invoke the assembler. However, we permit the assembler to accept the GNU as style argument --compress-debug-sections to maintain compatibility. Note, -gz/-gz= does *NOT* imply -g. That is, you need to additionally specific -g for debug information to be generated. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@306115 91177308-0d34-0410-b5e6-96231b3b80d8

* Driver: add support for `-gz` and `-gz=`Saleem Abdulrasool2017-06-111-3/+16
| | | | | | | | | | | | | | | | | These options control the behaviour of the compression of debug info sections on ELF targets. Our behaviour slightly diverges from the behaviour of GCC. `-gz` maps to the `-compress-debug-sections` rather than `-compress-debug-sections=zlib` or `-compress-debug-sections=zlib-gnu`. This small divergence allows us to be compatible across versions of binutils (=zlib support was introduced in 2.26, while earlier versions only support =zlib-gnu). This also allows users to not have to worry about the version of the assembler they may be using if they are not using the IAS. Previously, users would have had to go through the internal option `-compress-debug-sectionss` and pass that through to the assembler, which is no longer needed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@305165 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | A suspended translation unit uses significantly less memory but on the other side does not support any other calls than clang_reparseTranslationUnit to resume it or clang_disposeTranslationUnit to dispose it completely. This helps IDEs to reduce the memory footprint. The data that is freed by a call to clang_suspendTranslationUnit will be re-generated on the next (re)parse anyway. Used with a preamble, this allows pretty fast resumption of the translation unit for further use (compared to disposal of the translation unit and a parse from scratch).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is recommit of r302775, reverted in r302777 due to a fail in clang-tidy. Original mesage is below. Now if clang driver is given wrong arguments, in some cases it continues execution and returns zero code. This change fixes this behavior. The fix revealed some errors in clang test set. File test/Driver/gfortran.f90 added in r118203 checks forwarding gfortran flags to GCC. Now driver reports error on this file, because the option -working-directory implemented in clang differs from the option with the same name implemented in gfortran, in clang the option requires argument, in gfortran does not. In the file test/Driver/arm-darwin-builtin.c clang is called with options -fbuiltin-strcat and -fbuiltin-strcpy. These option were removed in r191435 and now clang reports error on this test. File arm-default-build-attributes.s uses option -verify, which is not supported by driver, it is cc1 option. Similarly, the file split-debug.h uses options -fmodules-embed-all-files and -fmodule-format=obj, which are not supported by driver. Other revealed errors are mainly mistypes.

* [ASTImporter] Improve handling of incomplete typesSean Callanan2017-05-131-2/+44
| | | | | | | | | | | | | | | | | | | | | | ASTImporter has some bugs when it's importing types that themselves come from an ExternalASTSource. This is exposed particularly in the behavior when comparing complete TagDecls with forward declarations. This patch does several things: - Adds a test case making sure that conflicting forward-declarations are resolved correctly; - Extends the clang-import-test harness to test two-level importing, so that we make sure we complete types when necessary; and - Fixes a few bugs I found this way. Failure to complete types was one; however, I also discovered that complete RecordDecls aren't properly added to the redecls chain for existing forward declarations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@302975 91177308-0d34-0410-b5e6-96231b3b80d8

* Driver must return non-zero code on errors in command lineSerge Pavlov2017-05-111-27/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now if clang driver is given wrong arguments, in some cases it continues execution and returns zero code. This change fixes this behavior. The fix revealed some errors in clang test set. File test/Driver/gfortran.f90 added in r118203 checks forwarding gfortran flags to GCC. Now driver reports error on this file, because the option -working-directory implemented in clang differs from the option with the same name implemented in gfortran, in clang the option requires argument, in gfortran does not. In the file test/Driver/arm-darwin-builtin.c clang is called with options -fbuiltin-strcat and -fbuiltin-strcpy. These option were removed in r191435 and now clang reports error on this test. File arm-default-build-attributes.s uses option -verify, which is not supported by driver, it is cc1 option. Similarly, the file split-debug.h uses options -fmodules-embed-all-files and -fmodule-format=obj, which are not supported by driver. Other revealed errors are mainly mistypes.
