Add a simple type-safe bit-mangling pointer union class.  This allows

  ///    Z = P.get<double*>();  // does not compile.
  ///    P = (float*)0;

Replace the PointerLikeTypeTraits::getNumLowBitsAvailable
function with a new NumLowBitsAvailable enum, which makes the
value available as an integer constant expression.

Add PointerLikeTypeTraits specializations for Instruction* and
Use** since they are only guaranteed 4-byte aligned.

Enhance PointerIntPair to know about (and enforce) the alignment
specified by PointerLikeTypeTraits.  This should allow things
like PointerIntPair<PointerIntPair<void*, 1,bool>, 1, bool>
because the inner one knows that 2 low bits are free.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@67930 91177308-0d34-0410-b5e6-96231b3b80d8

Optimize some 64-bit multiplication by constants into two lea's or one lea + shl since imulq is slow (latency 5). e.g.
x * 40

shlq    $3, %rdi
leaq    (%rdi,%rdi,4), %rax

This has the added benefit of allowing more multiply to be folded into addressing mode. e.g.
a * 24 + b
=>
leaq    (%rdi,%rdi,2), %rax
leaq    (%rsi,%rax,8), %rax

no need for eh info

fix warning in -asserts mode.

fix some warnings in release-asserts mode.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@67738 91177308-0d34-0410-b5e6-96231b3b80d8

fix an apparently real bug exposed by a warning in -asserts mode.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@67737 91177308-0d34-0410-b5e6-96231b3b80d8

fix warning in -asserts build.

Add testcase for r67728.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@67729 91177308-0d34-0410-b5e6-96231b3b80d8

Match this pattern so that we can generate simpler code:

  %a = ...
  %b = and i32 %a, 2
  %c = srl i32 %b, 1
  %d = br i32 %c,

into

  %a = ...
  %b = and %a, 2
  %c = X86ISD::CMP %b, 0
  %d = X86ISD::BRCOND %c ...

This applies only when the AND constant value has one bit set and the SRL
constant is equal to the log2 of the AND constant. The back-end is smart enough
to convert the result into a TEST/JMP sequence.

Skip debug info one more place.  (This one gets
called from llc, not opt, but it's an IR level
optimization nevertheless.)

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@67724 91177308-0d34-0410-b5e6-96231b3b80d8

Before deleting a basic block, give other loop passes a chance cleanup analysis values, related to the instructions in the basic block.

Modify getRegisterValueType() to allow for a register being in mutliple
register classes. Before, MVT::Other would be returned anytime a reg was
in multiple register classes. Now, MVT::Other is only returned if the types
for those register classes differ.

Add a test case for PR3779: when to promote the function return value.

Revert 67132. This is breaking some objective-c apps.
Also fixes SDISel so it *does not* force promote return value if the function is not marked signext / zeroext.

One more test.

When optimizing with debug info, don't keep the
stoppoint nodes around until Legalize; doing this
imposed an ordering on a sequence of loads that
came from different lines, interfering with scheduling.

Add __builtin___memcpy_chk tests.

These tests pass on linux.

Add a __builtin_object_size test.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@67688 91177308-0d34-0410-b5e6-96231b3b80d8

Fix a bug in our autoupgrade support: in an argument list to a function
call, we should treat "i64 zext" as the start of a constant expr, but
"i64 0 zext" as an argument with an obsolete attribute on it (this form
is already tested by test/Assembler/2007-07-30-AutoUpgradeZextSext.ll).

Make the autoupgrade logic more discerning to avoid treating "i64 zext"
as an old-style attribute, causing us to reject a valid constant expr.
This fixes PR3876.

Do not ignore DW_TAG_class_type!

CodeGen still defaults to non-verbose asm, but llc now overrides it and default to verbose.

Don't print global names twice with -asm-verbose.
