| | | | | | | | | | | This was accidentally removed in r260506, even though we only support non-allocatable global register variables. The general (allocatable) case is explicitly not supported.

* Driver: Remove support for -fobjc-gc*Duncan P. N. Exon Smith2016-12-071-10/+0
| | | | | | | | | | | | As a first step toward removing Objective-C garbage collection from Clang, remove support from the driver. I'm hoping this will flush out any expected bots/configurations/whatever that might rely on it. I've left the options behind temporarily in -cc1 to keep tests passing. I'll kill them off entirely in a follow up when I've had a chance to update/delete the rest of Clang. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@288872 91177308-0d34-0410-b5e6-96231b3b80d8

* Extend CompilationDatabase by a field for the output filenameJoerg Sonnenberger2016-12-011-0/+3
| | | | | | | | | | | | | | | In bigger projects like an Operating System, the same source code is often compiled in slightly different ways. This could be the difference between PIC and non-PIC code for static vs dynamic libraries, it could also be the difference between size optimised versions of tools for ramdisk images. At the moment, the compilation database has no way to distinguish such cases. As first step, add a field in the JSON format for it and process it accordingly.

* [analyzer] Minor fixes and improvements to debug.ExprInspectionArtem Dergachev2016-11-301-0/+39
| | | | | | | | | | | | | | | | | | | - Fix the bug with transition handling in ExprInspectionChecker's checkDeadSymbols implementation. - Test this bug by adding a new function clang_analyzer_numTimesReached() to catch number of passes through the code, which should be handy for testing against unintended state splits. - Add two more functions should help debugging issues quickly without running the debugger or dumping exploded graphs - clang_analyzer_dump() which dump()s an SVal argument to a warning message, and clang_analyzer_printState(), which dump()s the current program state to stderr.

* [Driver] Make -print-libgcc-file-name print compiler-rt lib when usedMichal Gorny2016-10-101-1/+2
| | | | | | | | | | | | | | | | | | | | Make the -print-libgcc-file-name option print an appropriate compiler runtime library, that is libgcc.a if gcc runtime is used and an appropriate compiler-rt library if that runtime is used. The main use for this is to allow linking executables built with -nodefaultlibs (e.g. to avoid linking to the standard C++ library) to the compiler runtime library, e.g. using: clang++ ... -nodefaultlibs $(clang++ ... -print-libgcc-file-name) in which case currently a program built like this linked to the gcc runtime unconditionally. The patch fixes it to use compiler-rt libraries instead when compiler-rt is the active runtime.
