* [Driver] Actually report errors during parsing instead of stopping when ↵Benjamin Kramer2017-06-301-0/+11
| | | | | | | | | | | | | | there's an error somewhere. This is a more principled version of r303756. That change was both very brittle about the state of the Diags object going into the driver and also broke tooling in funny ways. In particular it prevented tools from capturing diagnostics properly and made the compilation database logic fail to provide arguments to the tool, falling back to scanning directories for JSON files. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@306822 91177308-0d34-0410-b5e6-96231b3b80d8
* Driver must return non-zero code on errors in command lineSerge Pavlov2017-05-241-5/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [Driver] Add unit tests for Distro detectionMichal Gorny2016-11-282-0/+306
| | | | | | | | | | | | | Add a set of unit tests for the distro detection code. The tests use an in-memory virtual filesystems resembling release files for various distributions supported. All release files are provided (not only the ones directly used) in order to guarantee that one of the rules will not mistakenly recognize the distribution incorrectly due to the additional files (e.g. Ubuntu as Debian).

* [Driver] Set the default driver mode based on the executable.Zachary Turner2016-08-121-0/+25
| | | | | | | | | | | | | | | | | | Currently, if --driver-mode is not passed at all, it will default to GCC style driver. This is never an issue for clang because it manually constructs a --driver-mode option and passes it. However, we should still try to do as good as we can even if no --driver-mode is passed. LibTooling, for example, does not pass a --driver-mode option and while it could, it seems like we should still fallback to the best possible default we can. This is one of two steps necessary to get clang-tidy working on Windows.

The proposal to remove autoconf on 1/26 was discussed on the llvm-dev thread here: http://lists.llvm.org/pipermail/llvm-dev/2016-January/093875.html "This is the way [autoconf] ends Not with a bang but a whimper." -T.S.

* Minor fix in ToolChainTest.cpp to allow user defined GCC toolchain.Samuel Antao2015-10-271-4/+4
| | | | | | | | | If the user configured clang with a custom GCC toolchain that will take precedence on what the ToolChainTest.cpp expects to evaluate. This is fixed here by passing --gcc-toolchain= to the driver, in order to override any user defined GCC toolchain. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@251459 91177308-0d34-0410-b5e6-96231b3b80d8
