Craig Topper [Mon, 4 Jan 2016 03:05:14 +0000 (03:05 +0000)]
[TableGen] Fix a bug that caused the wrong name for a record built from a multiclass containing a defm called NAME that references another multiclass that contains a defm that uses NAME concatenated with other strings.

It would end up doing the concatenations from the second multiclass twice. This occured because SetValue detected a self assignment when trying to set the value of NAME to a VarInit called NAME. NAME is special here and it will get cleaned up later. So add a flag to suppress the self assignment check for this case.

Strangely the self-assignment error was returning false indicating it wasn't an error, but it wasn't doing the right thing. So this also changes it to report an error.

This fixes the names of some AVX512 FMA instructions that showed this double expansion.

[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.

expect '4' to be a portable or reliable pointer of this form. The only
reason this ever worked is because the PointerIntPair that this actually
gets used with has an artificially *low* presumed alignment that allowed
it to work. When the alignment of PointerIntPair is derived from the
actual type's alignment, the asserts start firing on this pointer. I'm
amazed we never managed to do anything that triggered the alignment
sanitizer with it, as this is just flat out UB.

If folks dislike this approach to providing a sentinel fragment address,
there are a myriad of other alternatives, suggestions welcome. But this
one has the distinct advantage of not requiring the friend dance of
