sched_getaffinity (Linux specific) has been available
* in glibc since 2002-08-08 (commit 972e719e8154eec5f543b027e2a08dfa285d55d5)
* in musl since the initial check-in.
gcc may warn here because X86ISD::NodeType is specified as "unsigned",
but ISD::NodeType is a naked C enum (although passed as an "unsigned"
throughout SDAG).
getFauxShuffle attempts to combine INSERT_VECTOR_ELT(TRUNCATE/EXTEND(EXTRACT_VECTOR_ELT(x))) patterns into a target shuffle chain.
PR45604 identified an issue where the scalar was truncated to a size smaller than the destination vector element and then zero extended back, which requires the upper bits to be zero'd which we don't currently do.
To avoid the bug I've added an early out in these truncation cases, a future commit should allow us to handle this by inserting the necessary SM_SentinelZero padding.
Summary: Add a command to dexp that exports index data in chosen format (e.g. YAML).

This is an enhancement to D77895 to avoid another
round-trip from XMM->GPR->XMM. This time we handle
the case of starting/ending with an f64 and casting
to signed i32 as the intermediate value.
It's a bit more involved than I initially assumed
because we need to use target-specific opcodes to
represent the non-standard cast ops.

bitcast (shuf V, MaskC) --> shuf (bitcast V), MaskC'
This is the widen shuffle elements enhancement to D76727.
It builds on the analysis and simplifications in
D77881 and rG6a7e958a423e.
The phase ordering tests show that we can simplify inverse
shuffles across a binop in both directions (widen/narrow or
narrow/widen) now.
There's another potential transform visible in some of the
remaining TODOs - move a bitcasted operand of a shuffle
after the shuffle.

We had partial coverage for some of these patterns, so removing duplicate tests
with the complete set in the new test file.
Reduce X86Subtarget.h/MCCodeEmitter.h/TargetMachine.h includes to forward declarations
Add explicit X86Subtarget.h/TargetMachine.h includes to X86AsmPrinter.cpp/X86MCInstLower.cpp
Remove unused MCSymbol forward declaration
We were only including MachineInstr.h for DebugLoc.h. This exposes an implicit include dependency in BTFDebug.h where I've had to add the MachineInstr.h include.
This makes it easier to extend the merge options in the future and also
reduces the risk of accidentally setting a wrong option.

Update misleading line in conclusions. Although the application to IR
objects is stated earlier, the concluding section contradicts it in
isolation.

Add getBase accessor so that underlying tree can be
manipulated in a similar manner to MachineDominatorTree.

LLJIT::defineAbsolute did not mangle its Name argument, which is inconsistent
with the behavior of other LLJIT methods (e.g. lookup). Since it is currently
unused anyway, this commit replaces it with a generic 'define' convenience
method for adding MaterializationUnits to the main JITDylib. This simplifies
use of the generic absoluteSymbols function (as well as the symbolAlias,
reexports and other functions that generate MaterializationUnits) with LLJIT.
First-order recurrences require special treatment when they are live-out;
such treatment is provided by fixFirstOrderRecurrence(), so they should be
included in AllowedExit set.
(Should probably have been included originally in D16197.)
Fixes PR45526: AllowedExit set is used by prepareToFoldTailByMasking() to
check whether the treatment for live-outs also holds when folding the tail,
which is not (yet) the case for first-order recurrences.
