Since our expression parser needs to locate areas of memory that are not in use when you have a process that can't JIT code, like core file debugging, the core file process plug-ins should be able to override the Process::GetMemoryRegionInfo(...) function.

In order to make this happen, I have added permissions to sections so that we can know what the permissions are for a given section, and modified both core file plug-ins to override Process::GetMemoryRegionInfo() and answer things correctly.

The out-of-tree build needs to read LLVM_TOOLS_INSTALL_DIR out of TOOLS_BINARY_DIR because LLVM_TOOLS_INSTALL_DIR is used by AddLLVM.cmake

So we can match sizeof expressions more accurately than with UnexposedExpr

MSVC doesn't allow std::atomic<>s in a union since they don't have trivial
copy constructor. Replacing them with e.g. std::atomic_int works, but that
breaks the GCC build on Linux, because then calls to e.g. std::atomic_load_explicit
fail, as they expect a real std::atomic<> pointer.

Fixing this with an #ifdef to unbreak the build for now.

Patch by David Binderman!

This reapplies commit r271930, r271915, r271923.  They hit a bug in
Thumb which is fixed in r272258 now.

The original message:

The code layout that TailMerging (inside BranchFolding) works on is not the
final layout optimized based on the branch probability. Generally, after
BlockPlacement, many new merging opportunities emerge.

This patch calls Tail Merging after MBP and calls MBP again if Tail Merging
merges anything.

This enables use of the 'S' constraint for inline ASM operands on
SystemZ, which allows for a memory reference with a signed 20-bit
immediate displacement. This patch includes corresponding documentation
and test case updates.

I've changed the 'T' constraint to match the new behavior for 'S', as
'T' also uses a long displacement (though index constraints are still
not implemented). I also changed 'm' to match the behavior for 'S' as
this will allow for a wider range of displacements for 'm', though
correct me if that's not the right decision.

Summary:
we want to exclude friend declaration, but the `DeclContext` of a
friend function declaration is not the class in which it is declared, so we need
to explicitly check if the parent is a `friendDecl`.

ReplaceTailWithBranchTo assumed that if an instruction is predicated, it must be part of an IT block. This is not correct for conditional branches.

No testcase as this was triggered by the reverted patch r272017 - test coverage will occur when that patch is re-reverted and there is no known way to trigger this in the meantime.

This is made possible by removing an assert in llc that assumed
MIRParser::parseLLVMModule would exit on error. MIRParser's documentation states
that it returns null if a parsing error occurs, so there's no reason to assert.
We can instead just fall through to where the check for a module is performed
and exit if it is null.

This commit is part of the clean-up after r269655.

[AVX512] Fix shuffle decode printing for several instructions with write masks. There are still more bugs here with UNPCK and PALIGN for sure. But these were the easiest ones to fix.

llvm-svn: 272252

If an immediate is only used in an AND node, it is possible that the immediate can be more optimally materialized when negated. If this is the case, we can negate the immediate and use a BIC instead;

  int i(int a) {
    return a & 0xfffffeec;
  }

Used to produce:
    ldr r1, [CONSTPOOL]
    ands r0, r1
  CONSTPOOL: 0xfffffeec

And now produces:
    movs    r1, #255
    adds    r1, #20  ; Less costly immediate generation
    bics    r0, r1

It is possible for a field and a class to have the same name.  In such
cases, performing lookup for the field might return a result set with
more than one entry.  An overzealous assertion fired, causing us to
crash instead of using the non-class lookup result.

This fixes PR28060.
