Justin Bogner ad560c4c11 CMake: Enable -Werror for the -fno-function-sections check 
If the -fno-function-sections flag isn't recognized, the compiler
emits a warning. This isn't enough to cause the check to fail, so we
enable -Werror as well.

Alexander Potapenko 2e7dc60ee3 [ASan] Replace the call to "vname" with "WRAP(vname)" in FORMAT_INTERCEPTOR_IMPL 
It's incorrect to call the function by its name in the interceptor, because that means WRAP(vname) on Linux and REAL(vname) on OSX.

This patch fixes asan/lit_tests/TestCases/printf-3.c on Mac.

Dmitry Vyukov 8aaa44c43d tsan: relax check for errno spoiling more 
We do not detect errno spoiling for SIGTERM,
because some SIGTERM handlers do spoil errno but reraise SIGTERM,
tsan reports false positive in such case.
It's difficult to properly detect this situation (reraise),
because in async signal processing case (when handler is called directly
from rtl_generic_sighandler) we have not yet received the reraised
signal; and it looks too fragile to intercept all ways to reraise a signal.

Some build environments are missing the required headers.

introduced READWRITE ioctl type.

Renato Golin 66e2b70e59 Enable compilation of RT on ARM 
Adding the ARM RT sources to the CMake files, and enabling some
sanitizers to also build on ARM. This is far from supported or
production quality, but enabling it to build will get us errors
that we can actually fix.

Having said that, the Compiler-RT and the Asan libraries are
know to work on some variations of ARM.

Alexander Potapenko 789e3e1b7c [ASan] Move the SIGSEGV/SIGBUS handling to sanitizer_common 
This change is a part of refactoring intended to have common signal handling behavior in all tools.
This particular CL moves InstallSignalHandlers() into sanitizer_common (making it InstallDeadlySignalHandlers()), but doesn't enable default signal handlers for any tool other than ASan.

implement the sigaction() functionality on Linux.
