the last compiler built for the previous flavour is used for the next,
for example the Debug clang compiler was being used for the initial build
of the Release LLVM.  Flavors should be independent of each other.  This
especially matters if the compiler built for the previous flavour doesn't
actually work!

Add test case for analyzer crash reported in <rdar://problem/10308201> (which is already fixed in mainline).

llvm-svn: 142606

AsmParser. This patch adds validation for target data layout strings upon
construction of TargetData objects. An attempt to construct a TargetData object
from a malformed string will trigger an assertion.

causing one of the unit tests to infinitely loop, which resulted in the 
buildbots stalling.

Parameterize the iteration count used when running benchmarks, instead of hard-coded inside the test case.
Add a '-y count' option to the test driver for this purpose.  An example:

 $  ./dotest.py -v -y 25 +b -p TestDisassembly.py

shadows a template parameter. Complain about the shadowing (or not,
under -fms-extensions), but don't invalidate the declaration. Merely
forget about the template parameter declaration.

actually just has an extraneous 'template<>' header, strip off the
'template<>' header and treat it as a normal friend tag. Fixes PR10660

compiler warnings.

llvm-svn: 142573

Refactor code from inlining and globalopt that checks whether a function definition is unused, and enhance it so it can tell that functions which are only used by a blockaddress are in fact dead.  This probably doesn't happen much on most code, but the Linux kernel's _THIS_IP_ can trigger this issue with blockaddress.  (GlobalDCE can also handle the given tescase, but we only run that at -O3.)  Found while looking at PR11180.

bring the debugger to the desired state.

This patch makes BenchBase inherit from TestBase, instead of Base (which is a parent class of
TestBase).  This is so that we can also enjoy the Pythonic way of bringing the lldb debugger
to a desired state before running the benchmark and collect statistics.

llvm-svn: 142562

std::string and modified all places that used the std::string it returned
to use the "const char *".

Also modified the expression parser to not crash when a function type fails
to copy into the expression AST context.
