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.

[X86] Add intrinsics for reading and writing to the flags register

LLVM's targets need to know if stack pointer adjustments occur after the
prologue.  This is needed to correctly determine if the red-zone is
appropriate to use or if a frame pointer is required.

Normally, LLVM can figure this out very precisely by reasoning about the
contents of the MachineFunction.  There is an interesting corner case:
inline assembly.

The vast majority of inline assembly which will perform a push or pop is
done so to pair up with pushf or popf as appropriate.  Unfortunately,
this inline assembly doesn't mark the stack pointer as clobbered
because, well, it isn't.  The stack pointer is decremented and then
immediately incremented.  Because of this, LLVM was changed in r256456
to conservatively assume that inline assembly contain a sequence of
stack operations.  This is unfortunate because the vast majority of
inline assembly will not end up manipulating the stack pointer in any
way at all.

Instead, let's provide a more principled solution: an intrinsic.
FWIW, other compilers (MSVC and GCC among them) also provide this
functionality as an intrinsic.

[TableGen] Modify the AsmMatcherEmitter to only apply the table growth from r252440 to the Hexagon target.

This restores the previous behavior of not including the mnemonic in the classes table for every target that starts instruction lines with the mnemonic. Not only did the table size increase by 1 entry, but the class enum increased in size which caused every class in the array to increase in size. It also grew the size of the function that parsers tokens into classes by a substantial amount.

This adds a new HasMnemonicFirst flag to all AsmParsers. It's set to 1 by default and Hexagon target overrides it to 0.

For the X86 target alone this recovers 324KB of size on the llvm-mc executable.

I believe the current state is still a bad design choice for the Hexagon target as it causes most of the parsing to do a linear search through the entire match table to comparing operands against every instruction until it finds one that works. At least for the other targets we do a binary search based on mnemonic over which to do the linear scan.

an sdiv gets wrongly converted to udiv.

[ptr-traits] Implement the base pointer traits using the actual
alignment of the pointee type!

This is the culmination of the ptr-traits work. Now the compiler will
catch me if I try to use a pointer to an empty struct as a key in
a dense map or inside a PointerIntPair or PointerUnion! This is much,
much better than sometimes corrupting data (and other times working
fine) due to insufficient alignment.

It also means that we will be much more diligent about rejecting other
uses of these constructs that aren't safe.

It also means that we can now be more aggressive with the constructs
when we actually have guaranteed higher alignment without specializing
stuff. I'll be going through and cleaning up all the current overrides
of these traits which are no longer necessary.

6 years ago[ptr-traits] Refactor how PointerIntPair does its pointer manipulation
Chandler Carruth [Wed, 30 Dec 2015 03:56:19 +0000 (03:56 +0000)]
[ptr-traits] Refactor how PointerIntPair does its pointer manipulation
to isolate it in a dependent helper class.

Without doing this, we end up requiring all of the pointer traits the
moment you even define a PointerIntPair. That makes them *incredibly*
hard to use, for example you can't use them at all inside a class for
pointers to that class!

This change sinks all the logic into a helper template class that only
needs to be fully instantiated when *using* the PointerIntPair. We still
get compile-time checking, but it is deferred long enough to make
tradition out-of-line method definitions (or just the normal deferred
method body parsing) sufficient to handle cycling references.
