Duncan Sands 514db117bd Some reassociate optimizations create new instructions, which they insert just
before the expression root.  Any existing operators that are changed to use one
of them needs to be moved between it and the expression root, and recursively
for the operators using that one.  When I rewrote RewriteExprTree I accidentally
inverted the logic, resulting in the compacting going down from operators to
operands rather than up from operands to the operators using them, oops.  Fix
this, resolving PR12963.

we're not using it.

Chandler Carruth aa324c9078 Clean up the 'check' CMake build rule a bit, notable renaming it to
'check-llvm'.

Don't worry! 'check' still works! =] To rationalize the names of targets
used to run tests, the vague plan is the following:

make check-llvm  # run LLVM reg/unit tests  (currently 'check')
make check-clang # run Clang reg/unit tests (currently 'clang-test')
make check-rt    # run CompilerRT reg/unit tests
make check-asan  # run ASan reg/unit tests (subset of -rt)
make check-tsan  # run TSan reg/unit tests (subset of -rt)
make check-all   # run as much of the above as is available

The last one respects what projects are checked out and built for
a given tree. Personally, I would like to eventually make 'check' be an
alias for 'check-all'. For now however, it is an alias for 'check-llvm',
and thus no behavior has changed.

While this patch and my plan only really apply to CMake, I think it
might be good to similarly rationalize the naming scheme for the Make
builds.

Chandler Carruth 9aaf156f30 Add support for building the ASan instrumentation unit tests with the
just-built Clang binary, and linking them against the just-built ASan
runtime.

This is *very* brittle. I expect it will require tweaking, and I've
pro-actively disabled it on non-Unix builds and on cross-builds.

It is also currently missing dependency edges on GoogleTest header files
and a few other corner cases, but those can be fixed. This is the major
milestone of a mini-bootstrap-like build of the unittest.

Timur Iskhodzhanov 29161d9886 Add a few (currently failing) tests for the PR13207 (template mangling in the presence of back references).
I've added an extra FileCheck pass for that with an extra "CURRENT" prefix.
I've carefully chosed the CURRENT/CORRECT prefixes so they
a) are self-descriptive
b) have the same length so the mangling between the current and the correct version is obvious

Feel free to ask me to change the prefixes if you know a better alternative.

appropriate debugging printing routine based on the type of the debug
information.

Evan Cheng 319be53a1f Remove a instcombine transform that (no longer?) makes sense:
// C - zext(bool) -> bool ? C - 1 : C
    if (ZExtInst *ZI = dyn_cast<ZExtInst>(Op1))
      if (ZI->getSrcTy()->isIntegerTy(1))
        return SelectInst::Create(ZI->getOperand(0), SubOne(C), C);

This ends up forming sext i1 instructions that codegen to terrible code. e.g.
int blah(_Bool x, _Bool y) {
  return (x - y) + 1;
}
=>
        movzbl  %dil, %eax
        movzbl  %sil, %ecx
        shll    $31, %ecx
        sarl    $31, %ecx
        leal    1(%rax,%rcx), %eax
        ret


Without the rule, llvm now generates:
        movzbl  %sil, %ecx
        movzbl  %dil, %eax
        incl    %eax
        subl    %ecx, %eax
        ret

It also helps with ARM (and pretty much any target that doesn't have a sext i1 :-).

The transformation was done as part of Eli's r75531. He has given the ok to
remove it.

Benjamin Kramer efe4028693 Implement getHostCPUName for ARM/linux. This will be used to implement -march=native in clang.
The cpuid registers are only available in privileged mode so we don't have
an OS-independent way of implementing this. ARM doesn't provide a list of
processor IDs so the list is somewhat incomplete.

Tim Northover e5629966df Teach TableGen to put chains on more instructions
When generating selection tables for Pat instances, TableGen relied on

correct code can be generated even if Pattern is unset.

Richard Trieu 9184423984 Add template type diffing to Clang. This feature will provide a better
comparison between two templated types when they both appear in a diagnostic.
Type elision will remove indentical template arguments, which can be disabled
with -fno-elide-type.  Cyan highlighting is applied to the differing types.

For more formatting, -fdiagnostic-show-template-tree will output the template
type as an indented text tree, with differences appearing inline. Template
tree works with or without type elision.
