Anna Zaks 136e9f466e [asan][docs] Fix the documentation to use clang++ for the C++ example
After Darwin has been updated not to link in stdc++ on Darwin this actually
started to break.

Michael Kuperstein 94b25ecdc0 Bring back note about not supporting global register variables.
This was accidentally removed in r260506, even though we only support
non-allocatable global register variables. The general (allocatable) case
is explicitly not supported.

Duncan P. N. Exon Smith c9073fa806 Driver: Remove support for -fobjc-gc*
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.

Joerg Sonnenberger 399aea300f Extend CompilationDatabase by a field for the output filename
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.

Artem Dergachev 30ed5467a4 [analyzer] Minor fixes and improvements to debug.ExprInspection
- 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.

Bruno Cardoso Lopes ed84df008f [Modules] Add 'no_undeclared_includes' module map attribute
The 'no_undeclared_includes' attribute should be used in a module to
tell that only non-modular headers and headers from used modules are
accepted.

The main motivation behind this is to prevent dep cycles between system
libraries (such as darwin) and libc++.

Michal Gorny 7cfe480122 [Driver] Make -print-libgcc-file-name print compiler-rt lib when used
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.
