Clear FunctionLocalMDs in purgeFunction along with the rest of the
function-specific state.

Fix whitespace.

llvm-svn: 112056

Eliminate an unnecessary cast.

llvm-svn: 112055

Add braces to fix dangling else.

llvm-svn: 111896

Extend function-local metadata to be usable as attachments.

llvm-svn: 111895

When we know we have an MDValue or MDString, call EnumerateMetadata
directly instead of going through EnumerateValue.

llvm-svn: 111894

Simplify this code. NamedMDNode operands are MDNodes.

llvm-svn: 111892

Make NamedMDNode not be a subclass of Value, and simplify the interface
for creating and populating NamedMDNodes.

Fix whitespace.

llvm-svn: 108569

Tidy.

Speedup bitcode writer. Do not walk all values for all functions to emit function local metadata. In one testcase, probably worst case scenario, the 70x speed up is seen.

Add special case bitcode support for DebugLoc. This avoids
having the bitcode writer materialize mdnodes for all the
debug location tuples when writing out the bc file and
stores the information in a more compact form. For example,
the -O0 -g bc file for combine.c in 176.gcc shrinks from
739392 to 512096 bytes.

This concludes my planned short-term debug info work.

Make the side-numbering of instructions used by metadata (which is needed to
keep track of instructions that return void) per-function. This fixes PR5278.

This breaks backwards compatibility with the metadata format. That's okay
because we haven't released the metadata bitcode yet.

Respect operator precedence (and silence a gcc 4.3 warning).

Remove MetadataBase class because it is not adding significant value.

Enumerate function-local metadata (and its types and operands) only during function-incorporation, global metadata continues to be enumerated during creation of ValueEnumerator

NamedMDNode is never used so there is no need to enumerate it here.

Derive NamedMDNode from Value.

Use separate namespace for named metadata.

Allow null to be an element of NamedMDNode. e.g. !llvm.stuff = !{!0, !1, null}
