Jingyue Wu 3203818bf7 [NVPTX] noop when kernel pointers are already global
Summary:
Some front ends make kernel pointers global already. In that case,
handlePointerParams does nothing.

Marek Olsak cfbdba2d0b AMDGPU: really don't commute REV opcodes if the target variant doesn't exist
If pseudoToMCOpcode failed, we would return the original opcode, so operands
would be swapped, but the instruction would remain the same.
It resulted in LSHLREV a, b ---> LSHLREV b, a.

This fixes Glamor text rendering and
piglit/arb_sample_shading-builtin-gl-sample-mask on VI.

Toma Tabacu 7bc44dcb0c [mips] [IAS] Fix parsing of memory offset expressions with parenthesis depth >1.
Summary:
In an expression such as "(((a+b)+c)+d)", parseParenExpression() would only parse the "a+b)+c", which would result in an error later on in the parser.
This means that we can only parse one level of inner parentheses.

In order to fix this, I added a new function called parseParenExprOfDepth(), which parses a specified number of trailing parenthesis expressions
(except for the outermost parenthesis), and changed MipsAsmParser to use it in parseMemOffset instead of parseParenExpression().

This avoids the need of using a magic value for the size, which had a few

Justin Bogner aa315fbb4c Hexagon: Paper over the undefined behaviour introduced by r238692
This stops shifting a 32-bit value by such absurd amounts as 96 and
120. We do this by dropping a call to the function that was doing this
entirely, which rather surprisingly doesn't break *any* tests.

I've also added an assert in the misbehaving function to prove that
it's no longer being called with completely invalid arguments.

This change looks pretty bogus and we should probably be reverting
r238692 instead, but this is hard to do with the number of follow ups
that have happened since. It can't be any worse than the undefined
behaviour that was happening before though.

This comes up under ubsan becauseRxSBGOperands is sometimes created

code should probably look into whether that's expected, as a 64 bit
mask may or may not be appropriate for such types.

Whereas vbroadcasti128 is more like:
    (v4i64 shuffle (v2i64 load), <0,1,0,1>)

This problem doesn't exist for vbroadcastf128, which kept matching
the intrinsic after r231182.  We should perhaps re-introduce the
intrinsic here as well, but that's a separate issue still being
discussed.

While there, add some proper vbroadcastf128 tests.  We don't currently
match those, like for loading vbroadcastsd/ss on AVX (the reg-reg
broadcasts where added in AVX2).
