Add intel_ocl_bicc calling convention as a function attribute to clang. The calling convention is already implemented in LLVM.

[sanitizer] increase the maximum size class of the fast allocator. This should save quite a bit of memory in tsan/msan (and later in asan). This also puts more stress on the large allocator. Add a couple of checks

(the old code won't work with new allocator)

the body of a functions. The problem was that hasBody looks at the entire chain
and causes problems to -fvisibility-inlines-hidden if the cache was not
invalidated.

Original message:

Cache visibility of decls.

This unifies the linkage and visibility caching. I first implemented this when
working on pr13844, but the previous fixes removed the performance advantage of
this one.
This is still a step in the right direction for making linkage and visibility
cheap to use.

llvm-svn: 171053

[asan] properly define ASAN_LOW_MEMORY. Due to a mistake it has been always true causing redzone and quarantine sizes to be smaller than it was some time before (and out of sync with the documentation). Also make one test less greedy

These are now generally used for all diagnostics from the backend, not just
for inline assembly, so this drops the "InlineAsm" from the names.  No
functional change.  (I've left aliases for the old names but only for long
enough to let me switch over clang to use the new ones.)

llvm-svn: 171047

"check-all" can be executed with 0 status, "check-all does nothing, no tools built."

LLVM_EXTERNAL_CLANG_BUILD=OFF LLVM_BUILD_TOOLS=OFF can reproduce this.
Oscar Fuentes reported this. Thank you.

This affords us to use std::string's allocation routines and use the destructor
for the memory management. Switching to that also means that we can use
operator==(const std::string&, const char *) to perform the string comparison
rather than resorting to libc functionality (i.e. strcmp).

When the backend is used from clang, it should produce proper diagnostics
instead of just printing messages to errs(). Other clients may also want to
register their own error handlers with the LLVMContext, and the same handler
should work for warnings in the same way as the existing emitError methods.

llvm-svn: 171041

Now we really pass -Wcovered-switch-default if the compiler supports it.

Apply all formatting changes that clang-format would apply to its own source
code. All choices seem to improve readability (or at least not make it worse).
No functional changes.

llvm-svn: 171039

This prevents formattings like this (assuming "parameter" doesn't fit the line):
  bool f = someFunction() && someFunctionWithParam(
      parameter) && someOtherFunction();

Here, "parameter" - the start of line 2 - has a parenthesis level of 2, but
there are subsequent tokens ("&&" and "someOtherFunction") with a lower level.
This is bad for readability as "parameter" hides "someOtherFunction". With this
patch, this changes to:
  bool f = someFunction() &&
           someFunctionWithParam(parameter) &&
           someOtherFunction();

(this breaks RPM packages)

This changes:
  int Result = a +  // force break
      b;
  return Result +  // force break
      5;

To:
  int Result = a +  // force break
               b;
  return Result +  // force break
         5;

[sanitizer] rework the size class map in the sanitizer allocator: make the differences between size classes more uniform.

to prevent assertion failures on code like "write(-1, ...)"

This fixes llvm.org/pr14686.

We used to add too many spaces for different versions of overloaded operator
function declarations/definitions. This patch changes, e.g.

  operator *() {}
  operator >() {}
  operator () () {}

to

  operator*() {}
  operator>() {}
  operator()() {}

llvm-svn: 171028

Removed "static" from "__jit_debug_descriptor" because "static" adds C++ mangling prefix to this symbol.

Some x86 instructions can load/store one of the operands to memory. On SSE, this memory needs to be aligned.
When these instructions are encoded in VEX (on AVX) there is no such requirement. This changes the folding
tables and removes the alignment restrictions from VEX-encoded instructions.
