update testcase to make sure we generate debug info for walrus
by adding a non-trivial constructor and verify that we don't
emit an ODR signature for the type.

This makes LLVM emit the same signature regardless of host and target endianess.

There doesn't appear to be any reason to put this variable on the heap.
I'm suspicious of the LexicalScope above that we stuff in a map and then
delete afterward, but I'm just trying to get the valgrind bot clean.

type units.

Initially this support is used in the computation of an ODR checker
for C++. For now we're attaching it to the DIE, but in the future
it will be attached to the type unit.

This also starts breaking out types into the separation for type
units, but without actually splitting the DIEs.

In preparation for hashing the DIEs this adds a DIEString type
that contains a StringRef with the string contained at the label.

Change the informal convention of DBG_VALUE machine instructions so that
we can express a register-indirect address with an offset of 0.
The old convention was that a DBG_VALUE is a register-indirect value if
the offset (operand 1) is nonzero. The new convention is that a DBG_VALUE
is register-indirect if the first operand is a register and the second
operand is an immediate. For plain register values the combination reg,
reg is used. MachineInstrBuilder::BuildMI knows how to build the new
DBG_VALUES.

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

Since the pool indexes are necessarily sequential and contiguous, just

Introduce some typedefs for DenseMaps containing SmallVectors so the vector size doesn't have to repeated when creating iterators for the DenseMap.

llvm-svn: 185508

Use SmallVectorImpl& instead of SmallVector& to avoid needlessly respecifying the small vector size.

Use SmallVectorImpl::iterator/const_iterator instead of SmallVector to avoid specifying the vector size.

[DebugInfo] Hold generic MCExpr in AddrPool

This changes the AddrPool infrastructure to enable it to hold
generic MCExpr expressions, not just MCSymbolRefExpr.

This is in preparation for supporting debug info for TLS variables
on PowerPC, where we need to describe the variable location using
a more complex expression than just MCSymbolRefExpr.

[DebugInfo] Introduce DIEExpr variant of DIEValue to hold MCExpr values

This partially reverts r185202 and restores DIELabel to hold plain
MCSymbol references.  Instead, we add a new subclass DIEExpr of
DIEValue that can hold generic MCExpr references.

This is in preparation for supporting debug info for TLS variables
on PowerPC, where we need to describe the variable location using
a more complex expression than just MCSymbolRefExpr.

This is dead code since PIC16 was removed in 2010. The result was an odd mix,
where some parts would carefully pass it along and others would assert it was
zero (most of the object streamer for example).

This is a precursor to adding debug info support for TLS which requires
non-default relocations applied to TLS symbols.
