Make the error message when we time out waiting for debugserver to reply to the qLaunchSuccess packet less cryptic.

The tablegen'd code does the same thing without this egregious duplication.
In my limited testing everything seems to work, however there can be
differences if the clang and llvm builtin definitions don't match.

This way the generated GCC builtin to LLVM intrinsic converter
actually works.

is a following clause.

The generated code uncovered an invalid prototype for __builtin_mips_shilo, fix it along the way.

Listen to the "--verbose" flag when running "crashlog" and if verbose is enabled, then dump full paths to source files and modules.

Changed much of the output that was coming out with "--verbose" over to use the new "--debug" flag.

Previously this caused a crash, since protocols are not interfaces.

 - recognize C++ new(std::nothrow) friends
 - ignore ExtractElement and ExtractValue instructions in size/offset analysis (all easy cases are probably folded away before we get here)
 - also recognize realloc as noalias

make LazyValueInfo analyze the default case of switch statements (we know that in the default branch the value cannot be any of the switch cases)

for tracking this.

handy. It can be done, but we would have to build a derived-to-base cast
during codegen to compute the correct this pointer.

I will handle covariant returns next.

Nothing in here makes use of the virtuality.

[asan] set a hard limit on the number of instructions instrumented pear each BB. This is (hopefully temporary) workaround for PR13225

[ASan] update cmake rules so that ASan unit tests can include googletest (and, hence, llvm) headers when they are built by fresh Clang

undefined behaviour, and move the diagnostic for '' from an Error into
an ExtWarn in this group. This is important for some users of the preprocessor,
and is necessary for gcc compatibility.

a dedicated helper function. This will enable re-using the same logic
for Clang's lit setup, etc.

llvm-svn: 159333

When both a load/store and its address computation are being vectorized, it can
happen that the address-computation vectorization destroys SCEV's ability
to analyize the relative pointer offsets. As a result (like with the aliasing
analysis info), we need to precompute the necessary information prior to
instruction fusing.

This was found during stress testing (running through the test suite with a very
low required chain length); unfortunately, I don't have a small test case.
