[CIR] Use the modern enum case classes
The `I32EnumAttrCase` family carries an `Attr` half, and an `IntegerAttr`
predicate with it, that a CIR enum has no use for now that the enums derive
from `EnumInfo`. Upstream says of those forms that they "are not needed when
using the newer `EnumCase` form".
Rename all 198 of them to `I32EnumCase`, `I32BitEnumCaseNone`,
`I32BitEnumCaseBit` and `BitEnumCaseGroup`. The group class drops its width
prefix because the modern spelling takes the width from its cases.
NFC, mechanical.
[CIR] Derive lowering attr names from cppClassName, not the def name
CIRLoweringEmitter built its CXX_ABI_ALWAYS_LEGAL_ATTRS entries with
GetOpCppClassName, which splits the TableGen def name at the first
underscore. That works only while every def is named CIR_<CppClassName>Attr.
When one is not, the emitter writes an `isa<>` for a class that does not
exist, and the failure lands as a compile error in generated code.
Attributes carry the authoritative name in cppClassName, which
GenerateAttrToValueVisitor was already reading. Factor that out as
GetAttrCppClassRef and use it for both attribute paths. GetOpCppClassName
stays for operations.
NFC, and checkable. No CIR attribute overrides cppClassName, so the generated
CIRLowering.inc is byte-identical.
[CIR] Drop the redundant suffix from the inline kind mnemonic
inline_kind was the one CIR enum attribute mnemonic still repeating what its
C++ enum class name says. The attribute now spells
`#cir.inline<always_inline>`. The operation argument keeps the name
inline_kind, since that is the accessor name, so the printed form reads
`inline_kind = #cir.inline<always_inline>`.
The enum's summary also becomes "inline kind" rather than the camelCase
"inlineKind", which is what generated docs show now that CIR_InlineKindAttr
no longer overrides it.
25 CHECK lines change across four test files. Nine are in an
aarch64-registered-target test, unsupported in an X86-only build, but the
substitution matches the two CIR tests that do run.
[CIR] Drop dead ceremony around the CIR enum attributes
Five things that no longer earn their place in the CIR enum attribute
machinery.
CIR_CleanupKindAttr carried three. Its cppClassName restated the default
AttrDef already derives. Its skipDefaultBuilders plus hand-written
AttrBuilder existed only to default $value to CleanupKind::All, which no
caller relies on, so the generated builders stayed suppressed for nothing.
And its summary and description restated the name, overriding the enum's own
"cleanup kind" that EnumAttr would otherwise inherit. The isNormal, isEH and
isNormalAndEH helpers stay.
CIR_TLSModelAttr's summary restated its name the same way, so only that goes.
CIR_DefaultValuedEnumParameter has never had a user.
NFC.
[CIR] Move the CIR enums off the legacy EnumAttrInfo hierarchy
MLIR has two enum hierarchies. `EnumAttrInfo` doubles as an `IntegerAttr`
constraint, so every CIR enum had to clear `genSpecializedAttr` to say it did
not want one. `EnumInfo` describes a C++ enum and nothing more.
Derive the CIR bases from `I32Enum`, `I64Enum` and `I32BitEnum`, and widen
`CIR_EnumAttr` to the `EnumInfo` that upstream `EnumAttr` already takes. The
flag no longer exists to clear. `FPClassTestEnum` gets unquoted printing from
`BitEnumBase` rather than overriding `printBitEnumQuoted`, and
`CIR_KnownFuncKind` drops a `parameterPrinter` the generated `operator<<`
now covers, still spelling `#cir.func_identity<"std::find">`.
AMDGPU wraps an `I32Enum` in an `EnumAttr` with this same bracketed format.
Parsing moves to the generated `FieldParser`, whose diagnostic names the
accepted spellings, so two `expected-error` lines change. Generated attribute
code drops 16 KB as 28 inlined parsers collapse into it.
[CIR] Migrate the FPClassTest bit enum and unquote its flags
cir.is_fp_class printed its flags inconsistently. Single-bit values came out
bare, as in `fcSNan`, while group values and combinations came out quoted, as
in `"fcInf"` and `"fcSNan|fcNegInf"`. That comes from I32BitEnumAttr setting
printBitEnumQuoted, which EnumAttr.td keeps only for backwards compatibility.
Clearing the bit and using the `enum` directive selects the separator-aware
parser and printer, so every value now spells unquoted:
cir.is_fp_class %x, fcSNan|fcNegInf : (!cir.float) -> !cir.bool
The enum also drops its specialized IntegerAttr for a CIR_EnumAttr wrapper,
giving it the standalone spelling `#cir.fp_class<fcSNan|fcNegInf>`. This
changes operation syntax, so it updates 37 CHECK lines.
[CIR] Migrate GlobalLinkageKind, CallingConv and SideEffect off IntegerAttr
GlobalLinkageKind, CallingConv and SideEffect generated IntegerAttr
subclasses with no dialect spelling of their own. Each now sets
genSpecializedAttr = 0 and gains a CIR_EnumAttr wrapper, and cir.global wraps
$linkage in `enum()`. GlobalLinkageKind spells `#cir.linkage<internal>`,
dropping both the `global_` prefix and the `_kind` suffix.
cir.func and cir.call print all three by hand, but they stream
stringifyGlobalLinkageKind(getLinkage()) and friends, which take the enum
rather than the attribute, so those sites are unchanged.
Operation syntax is unchanged.
[CIR] Migrate AssumeBundleKind, AtomicFetchKind and AsmFlavor off IntegerAttr
AssumeBundleKind, AtomicFetchKind and AsmFlavor generated IntegerAttr
subclasses with no dialect spelling of their own. Each now sets
genSpecializedAttr = 0 and gains a CIR_EnumAttr wrapper.
Unlike the other CIR operation enums, these three are reached through
hand-written parsers and printers, so they needed checking individually.
cir.atomic.fetch references $binop declaratively and gains an `enum()`
wrapper. The other two need no change, since printAssumeBundle is already
typed on cir::AssumeBundleKindAttr and InlineAsmOp::print streams the enum
rather than the attribute.
Operation syntax is unchanged.
[CIR] Migrate MemOrder and SyncScopeKind off IntegerAttr
MemOrder and SyncScopeKind, the enums the atomic operations share, generated
IntegerAttr subclasses with no dialect spelling of their own.
Both now set genSpecializedAttr = 0 and gain CIR_EnumAttr wrappers, spelling
`#cir.mem_order<seq_cst>` and `#cir.sync_scope<system>`, and the atomic
operations wrap their arguments in `enum()` to keep the bare keyword.
`enum()` works as an optional-group anchor, so the `syncscope` and `atomic`
groups on cir.load and cir.store are unaffected. Operation syntax is
unchanged.
[VPlan][Predicator] Preserve some uniform control flow
Implements "Partial Control-Flow Linearization" by Simon Moll and
Sebastian Hack.
That should allow implementation of an alternative to
https://github.com/llvm/llvm-project/pull/141900 based on this
functionality (see BOSCC in the paper).
[VPlan] Use compact RPOT instead of just RPOT
This is necessary for the future partial linearization change, but I
wanted to commit this bit independently because it changes some tests on
itself and could potentially provide more blend optimization
opportunites (at least I hoped) but that didn't seem to happen.
