Add missing parenthesis such that all and not only the very first attribute
is checked.

Testing this piece of code is not possible with an LLVM-IR test file, as the
LLVM-IR parser has a similar check such that the wrong IR does not even arrive
at the verifier.

No functionality change. It should suffice to check the type of a debug info
metadata, instead of calling Verify.

No functionality change. Remove handling for the null case.

ConstantFold: Check that truncating the other side is safe under a sext when trying to remove a sext from a compare.

Fixes PR16462.

It should suffice to check the type of a debug info metadata, instead of
calling Verify. For cases where we know the type of a DI metadata, use
assert.

The Builtin attribute is an attribute that can be placed on function call site that signal that even though a function is declared as being a builtin,

Representing enumerators by int64 instead of uint64 for now. At some

DebugInfo: When asm printing include a '[def]' tag for tag decls that are definitions (& rename the 'fwd' tag to 'decl' for clarity)

This change is version locked with a change in Clang, so expect some
transient buildbot fallout.

Turns out all the references were in llvm and not in clang.

This pass was assuming that if hasAddressTaken() returns false for a
function, the function's only uses are call sites.  That's not true
because there can be references by BlockAddresses too.

Fix the pass to handle this case.  Fix
BlockAddress::replaceUsesOfWithOnConstant() to allow a function's type
to be changed by RAUW'ing the function with a bitcast of the recreated
function.

Patch by Mark Seaborn.

The effect of llvm.used is to introduce an invisible reference, so this seems
a reasonable restriction. It will be used to provide an easy ordering of
the entries in llvm.used.

Other than recognizing the attribute, the patch does little else.
It changes the branch probability analyzer so that edges into
blocks postdominated by a cold function are given low weight.

Added analysis and code generation tests.  Added documentation for the
new attribute.

- move AsmWriter.h from public headers into lib
- marked all AssemblyWriter functions as non-virtual; no need to override them
- DebugIR now "plugs into" AssemblyWriter with an AssemblyAnnotationWriter helper
- exposed flags to control hiding of a) debug metadata b) debug intrinsic calls

There were bits & pieces of code lying around that may've given the
impression that debug info metadata supported the possibility that a
subprogram's type could be specified by a non-subroutine type describing
the return type of a void function. This support was incomplete &
unnecessary. Asserts & API have been changed to make the desired usage
more clear.

This resolves the last of the PR14606 failures in the GDB 7.5 test
suite by implementing an optional name field for
DW_TAG_imported_modules/DIImportedEntities and using that to implement
C++ namespace aliases (eg: "namespace X = Y;").

This is expanding Ben's original heuristic for short basic blocks to
also work for longer basic blocks and huge use lists.

Scan the basic block and the use list in parallel, terminating the
search when the shorter list ends. In almost all cases, either the basic
block or the use list is short, and the function returns quickly.

In one crazy test case with very long use chains, CodeGenPrepare runs
400x faster. When compiling ARMDisassembler.cpp it is 5x faster.

This is only tested for global variables at the moment (& includes tests
for the unnamed parameter case, since apparently this entire function
was completely untested previously)

- requires existing debug information to be present
- fixes up file name and line number information in metadata
- emits a "<orig_filename>-debug.ll" succinct IR file (without !dbg metadata
  or debug intrinsics) that can be read by a debugger
- initialize pass in opt tool to enable the "-debug-ir" flag
- lit tests to follow

llvm-svn: 181467

- made all functions virtual so that subclasses can specialize them
- add printInstructionLine so that subclasses can choose whether or not to
  print the newline character (without having to implement printBasicBlock()
- added a second constructor to AssemblyWriter that does not require a
  SlotTracker, as required in order to keep the SlotTracker helper class outside
  AsmWriter.h and buried in the implementation.

DIBuilder::createImportedDeclaration isn't fully plumbed through (note,
lacking in AsmPrinter/DwarfDebug support) but this seemed like a
sufficiently useful division of code to make the subsequent patch(es)
easier to follow.
