Justin Lebar 5a7df9c130 Call TargetMachine::addEarlyAsPossiblePasses from BackendUtil.
Summary:
As of D18614, TargetMachine exposes a hook to add a set of passes that should
be run as early as possible.  Invoke this hook from clang when setting up the
pass manager.

Chris Bieneman 31046054a8 [CMake] On Darwin bootstrap LTO builds set DYLD_LIBRARY_PATH instead of using llvm-ar
llvm-ar isn't really supported for Darwin, instead the host tools will load libLTO, so we can use the just-built libLTO.

This actually makes Darwin bootstrap builds a little faster because you don't need to build llvm-ar before starting the next stage.

Adrian Prantl 9bc3c4f373 Module debugging: Fix the DWO filename for PCH in a relative path.
PCH in a relative location had a redundant relative path on the DWO
filename and the DW_AT_compilation_dir.
This patch fixes this and adds testcases for PCH in the same directory,
in a relative, and an absolute location.

Summary:
I have exposed the following function through libclang and the clang.cindex python bindings:

clang_CXXConstructor_isConvertingConstructor,
clang_CXXConstructor_isCopyConstructor,
clang_CXXConstructor_isDefaultConstructor,
clang_CXXConstructor_isMoveConstructor,
clang_CXXMethod_isDefaulted

I need (some of) these methods for a C++ code model I am building in Python to drive a code generator.

Vassil Vassilev a4d7d783d0 [modules] Fix Decl's Used invariant.
The Decl::isUsed has a value for every decl. In non-module builds it is very
difficult (but possible) to break this invariant but when we walk up the redecl
chain we find the neccessary information.

When deserializing the decls from a module it is much more difficult to update
correctly this invariant. The patch centralizes the information whether a decl
is used in the canonical decl marking the entire entity as being used.

Fixes https://llvm.org/bugs/show_bug.cgi?id=27401

Patch by Cristina Cristescu and me.

Thanks to Richard Smith who helped to debug and understand the issue!

Nico Weber 197e5cfe34 Try to get at_file_missing.c passing after LLVM r267556.
r267556 made backslashes escape the next character
unconditionally in rsp files.  This test echos a path into
a rsp file, and paths contain backslashes on Windows. Since
it's not important for this test to get the filename from
the rsp file, just pass it regularly.

Samuel Antao 9092700683 [OpenMP] Improve mappable expressions Sema.
Summary:
This patch adds logic to save the components of mappable expressions in the clause that uses it, so that they don't have to be recomputed during codegen. Given that the mappable components are (will be) used in several clauses a new geneneric implementation `OMPMappableExprListClause` is used that extends the existing `OMPVarListClause`.

This patch does not add new tests. The goal is to preserve the existing functionality while storing more info in the clauses.

Nico Weber 47bf505775 driver: Add a `--rsp-quoting` flag to pick response file quoting.
Currently, clang-cl always uses Windows style for unquoting, and clang always
uses POSIX style for unquoting.

With this flag, it's possible to change these defaults.

In general, response file quoting should match the shell the response file is
used in.  On Windows, it's possible to run clang-cl in a bash shell, or clang in
cmd.exe, so a flag for overriding the default behavior is natural there.

On non-Windows, Windows quoting probably never makes sense (except maybe in
Wine), but having clang-cl behave differently based on the host OS seems
strange too.  So require that people who want to use posix-style response
files with clang-cl on non-Windows pass --rsp-quoting=posix.

Adrian Prantl 05fefa4a85 Module Debugging: Fix the condition for determining whether a template
instantiation is in a module.

This patch fixes the condition for determining whether the debug info for a
template instantiation will exist in an imported clang module by:

- checking whether the ClassTemplateSpecializationDecl is complete and
- checking that the instantiation was in a module by looking at the first field.

I also added a negative check to make sure that a typedef to a forward-declared
template (with the definition outside of the module) is handled correctly.

Alexey Bataev 7292c29bb5 [OPENMP 4.5] Codegen for 'taskloop' directive.
The taskloop construct specifies that the iterations of one or more associated loops will be executed in parallel using OpenMP tasks. The iterations are distributed across tasks created by the construct and scheduled to be executed.
The next code will be generated for the taskloop directive:
    #pragma omp taskloop num_tasks(N) lastprivate(j)
        for( i=0; i<N*GRAIN*STRIDE-1; i+=STRIDE ) {
          int th = omp_get_thread_num();
          #pragma omp atomic
            counter++;
          #pragma omp atomic
            th_counter[th]++;
          j = i;
    }

Generated code:
task = __kmpc_omp_task_alloc(NULL,gtid,1,sizeof(struct
task),sizeof(struct shar),&task_entry);
psh = task->shareds;
psh->pth_counter = &th_counter;
psh->pcounter = &counter;
psh->pj = &j;
task->lb = 0;
task->ub = N*GRAIN*STRIDE-2;
task->st = STRIDE;
