the front-end, if any, that something of interest happened.

- The severity of the report: How bad this is.

This patch also adds 2 classes:

will be used to switch to the new diagnostic API for LLVMContext::emitError.
- DiagnosticStackSize: For stack size reporting. Comes as a replacement of the

Quentin Colombet [Mon, 16 Dec 2013 23:22:51 +0000 (23:22 +0000)]
Add warning capabilities in LLVM.

The patch adds a new LLVMContext::diagnose that can be used to communicate to
the front-end, if any, that something of interest happened.
The diagnostics are supported by a new abstraction, the DiagnosticInfo class.
The base class contains the following information:
- The kind of the report: What this is about.
- The severity of the report: How bad this is.

This patch also adds 2 classes:
- DiagnosticInfoInlineAsm: For inline asm reporting. Basically, this diagnostic
will be used to switch to the new diagnostic API for LLVMContext::emitError.
- DiagnosticStackSize: For stack size reporting. Comes as a replacement of the
hard coded warning in PEI.

This patch also features dynamic diagnostic identifiers. In other words plugins
can use this infrastructure for their own diagnostics (for more details, see
getNextAvailablePluginDiagnosticKind).

This patch introduces a new DiagnosticHandlerTy and a new DiagnosticContext in
the LLVMContext that should be set by the front-end to be able to map these
diagnostics in its own system.

[AArch64]Fix the pattern match failure for v1i8/v1i16/v1i32 types.
Currently we have such types as legal vector types. The DAG combiner may generate some DAG nodes having such types but we don't have patterns to match them.
E.g. a load i32 and a bitcast i32 to v1i32 will be combined into a load v1i32:
     bitcast (load i32) to v1i32 -> load v1i32.
So this patch fixes such problems for load/dup instructions.
If v1i8/v1i16/v1i32 are not legal any more, the code in this patch can be deleted. So I also add some FIXME.

[Stackmap] Liveness Analysis Pass

This optional register liveness analysis pass can be enabled with either
-enable-stackmap-liveness, -enable-patchpoint-liveness, or both. The pass
traverses each basic block in a machine function. For each basic block the
instructions are processed in reversed order and if a patchpoint or stackmap
instruction is encountered the current live-out register set is encoded as a
register mask and attached to the instruction.

Later on during stackmap generation the live-out register mask is processed and
also emitted as part of the stackmap.

This information is optional and intended for optimization purposes only. This
will enable a client of the stackmap to reason about the registers it can use
and which registers need to be preserved.
