(Clang part of the patch is D15832).

When clang runs an external tool, e.g. a linker, it may create a command line that exceeds the length limit.

Clang uses the llvm::sys::argumentsFitWithinSystemLimits function to check if command line length fits the OS

limitation. There are two problems in this function that may cause exceeding of the limit:

1. It ignores the length of the program path in its calculations. On the other hand, clang adds the program

path to the command line when it runs the program.

2. It assumes no space character is inserted after the last argument, which is not true for Windows. The flattenArgs function adds the trailing space for *each* argument. The result of this is that the terminating NULL character is not counted and may be placed beyond the length limit if the command line is exactly 32768 characters long. The WinAPI's CreateProcess does not find the NULL character and fails.

The reason we can remove the predicates is that when MUBUF instructions
are legal, the instruction selector will prefer selecting those over
FLAT instructions because MUBUF patterns have a higher complexity score.
So, in this case having patterns for FLAT instructions will have no effect.

This change also simplifies the process for forcing global address space
loads to use FLAT instructions, since we no only have to disable the

[MemoryBuiltins] Remove isOperatorNewLike by consolidating non-null inference handling

This patch removes the isOperatorNewLike predicate since it was only being used to establish a non-null return value and we have attributes specifically for that purpose with generic handling. To keep approximate the same behaviour for existing frontends, I added the various operator new like (i.e. instances of operator new) to InferFunctionAttrs. It's not really clear to me why this isn't handled in Clang, but I didn't want to break existing code and any subtle assumptions it might have.

Once this patch is in, I'm going to start separating the isAllocLike family of predicates. These appear to be being used for a mixture of things which should be more clearly separated and documented. Today, they're being used to indicate (at least) aliasing facts, CSE-ability, and default values from an allocation site.

Joseph Tremoulet [Mon, 4 Jan 2016 16:16:01 +0000 (16:16 +0000)]
[WinEH] Update CoreCLR EH state numbering

Fix the CLR state numbering to generate correct tables, and update the lit
test to verify them.

The CLR numbering assigns one state number to each catchpad and

It also computes two tree-like relations over states:
 1) Each state has a "HandlerParentState", which is the state of the next
    outer handler enclosing this state's handler (same as nearest ancestor
    per the ParentPad linkage on EH pads, but skipping over catchswitches).
 2) Each state has a "TryParentState", which:
    a) for a catchpad that's not the last handler on its catchswitch, is
       the state of the next catchpad on that catchswitch.
    b) for all other pads, is the state of the pad whose try region is the
       next outer try region enclosing this state's try region.  The "try
       regions are not present as such in the IR, but will be inferred
       based on the placement of invokes and pads which reach each other
       by exceptional exits.

Catchswitches do not get their own states, but each gets mapped to the
state of its first catchpad.

Table generation requires each state's "unwind dest" state to have a lower
state number than the given state.

Since HandlerParentState can be computed as a function of a pad's
ParentPad, and TryParentState can be computed as a function of its unwind
dest and the TryParentStates of its children, the CLR state numbering
algorithm first computes HandlerParentState in a top-down pass, then
computes TryParentState in a bottom-up pass.

Also reword some comments/names in the CLR EH table generation to make the
distinction between the different kinds of "parent" clear.

AMDGPU: Avoid assertions after SGPR spilling failed

The comment explains it: emitError does not necessarily exit the compilation
process, and then using NoRegister leads to assertions later on.
This generates incorrect code, of course, but the user should know to not use
the result when an error has been emitted.

It would be nice to have a test-case for this inside the LLVM repository,
but llc exits on error. shader-db tests trigger the underlying issue at least
on Tonga.
