instantiated from corresponding templated definition. This behavior does

declaration of the friend `f` is created when the containing template
`X` is instantiated, but it does not have a body as per 14.5.4p4
because `f` is not odr-used.

[GlobalISel][AArch64] Adding -disable-gisel-legality-check CL option

Currently it's impossible to test InstructionSelect pass with MIR which
is considered illegal by the Legalizer in Assert builds. In early stages
of porting an existing backend from SelectionDAG ISel to GlobalISel,
however, we would have very basic CallLowering, Legalizer, and
RegBankSelect implementations, but rather functional Instruction Select
with quite a few patterns selectable due to the semi-automatic porting
process borrowing them from SelectionDAG ISel.

As we are trying to define legality as a property of being selectable by
the instruction selector, it would be nice to be able to easily check
what the selector can do in its current state w/o the legality check
provided by the Legalizer getting in the way.

It also seems beneficial to have a regression testing set up that would
not allow the selector to silently regress in its support of the MIR not
supported yet by the previous passes in the GlobalISel pipeline.

This commit adds -disable-gisel-legality-check command line option to
llc that disables those legality checks in RegBankSelect and
InstructionSelect passes.

It also adds quite a few MIR test cases for AArch64's Instruction
Selector. Every one of them would fail on the legality check at the
moment, but will select just fine if the check is disabled. Every test
MachineFunction is intended to exercise a specific selection rule and

number, ID, and index of its GIM_Try opcode in TableGen'erated

[X86] Make sure we don't combine (fneg (fma X, Y, Z)) to a target specific node when there are no FMA instructions.

This would cause a 'cannot select' error at isel when we should have emitted a lib call and an xor.

Fixes PR36553.

[NVPTX] Lower loads from global constants using ld.global.nc (aka LDG).

Summary:
After D43914, loads from global variables in addrspace(1) happen with
ld.global.  But since they're constants, even better would be to use
ld.global.nc, aka ldg.

6 years ago[NVPTX] Use addrspacecast instead of target-specific intrinsics in NVPTXGenericToNVVM.

[NVPTX] Use addrspacecast instead of target-specific intrinsics in NVPTXGenericToNVVM.

Summary:
NVPTXGenericToNVVM was using target-specific intrinsics to do address
space casts.  Using the addrspacecast instruction is (a lot) simpler.
But it also has the advantage of being understandable to other passes.
In particular, InferAddrSpaces is able to understand these address space
casts and remove them in most cases.
