funcType represents a function type.
A *Type for each in and out parameter is stored in an array that
directly follows the funcType (and possibly its uncommonType). So
a function type with one method, one input, and one output is:
struct {
funcType
uncommonType
[2]*rtype // [0] is in, [1] is out
}InCountuint16 // top bit is set if last input parameter is ...TypeType // alignment of variable with this type function for comparing objects of this type

IntArgRegBitmap is a bitmap large enough to hold one bit per
integer argument/return register. Get returns whether the i'th bit of the bitmap is set.
nosplit because it's called in extremely sensitive contexts, like
on the reflectcall return path. Set sets the i'th bit of the bitmap to 1.

Bytes*byte Data does pointer arithmetic on n's Bytes, and that arithmetic is asserted to
be safe because the runtime made the call (other packages use DataChecked) DataChecked does pointer arithmetic on n's Bytes, and that arithmetic is asserted to
be safe for the reason in whySafe (which can appear in a backtrace, etc.) HasTag returns true iff there is tag data following this name IsBlank indicates whether n is "_". IsEmbedded returns true iff n is embedded (an anonymous field). IsExported returns "is n exported?" Name returns the tag string for n, or empty if there is none. ReadVarint parses a varint as encoded by encoding/binary.
It returns the number of encoded bytes and the encoded value. Tag returns the tag string for n, or empty if there is none.

Offset is for computing offsets of type data structures at compile/link time;
the target platform may not be the host platform. Its state includes the
current offset, necessary alignment for the sequence of types, and the size
of pointers and alignment of slices, interfaces, and strings (this is for tearing-
resistant access to these types, if/when that is supported). // the required alignmentof the container // the current offset // the size of a pointer in bytes // the alignment of slices (and interfaces and strings) Align returns the offset obtained by aligning offset to a multiple of a.
a must be a power of two. D16 returns the offset obtained by appending a 16-bit field to o. D32 returns the offset obtained by appending a 32-bit field to o. D64 returns the offset obtained by appending a 64-bit field to o. D8 returns the offset obtained by appending an 8-bit field to o. Interface returns the offset obtained by appending an interface field to o. Offset returns the struct-aligned offset (size) of o.
This is at least as large as the current internal offset; it may be larger. D64 returns the offset obtained by appending a pointer field to o.( Offset) PlusUncommon() Offset Slice returns the offset obtained by appending a slice field to o. String returns the offset obtained by appending a string field to o.( Offset) align_(a uint8) Offset plus returns the offset obtained by appending a power-of-2-sized-and-aligned object to o.

RegArgs is a struct that has space for each argument
and return value register on the current architecture.
Assembly code knows the layout of the first two fields
of RegArgs.
RegArgs also contains additional space to hold pointers
when it may not be safe to keep them only in the integer
register space otherwise. // untyped float registers Values in these slots should be precisely the bit-by-bit
representation of how they would appear in a register.
This means that on big endian arches, integer values should
be in the top bits of the slot. Floats are usually just
directly represented, but some architectures treat narrow
width floating point values specially (e.g. they're promoted
first, or they need to be NaN-boxed). // untyped integer registers Ptrs is a space that duplicates Ints but with pointer type,
used to make pointers passed or returned in registers
visible to the GC by making the type unsafe.Pointer. ReturnIsPtr is a bitmap that indicates which registers
contain or will contain pointers on the return path from
a reflectcall. The i'th bit indicates whether the i'th
register contains or will contain a valid Go pointer.(*RegArgs) Dump() IntRegArgAddr returns a pointer inside of r.Ints[reg] that is appropriately
offset for an argument of size argSize.
argSize must be non-zero, fit in a register, and a power-of-two.
This method is a helper for dealing with the endianness of different CPU
architectures, since sub-word-sized arguments in big endian architectures
need to be "aligned" to the upper edge of the register to be interpreted
by the CPU correctly.

Package-Level Functions (total 19, in which 14 are exported)
CommonOffset returns the Offset to the data after the common portion of type data structures.
CommonSize returns sizeof(Type) for a compilation target with a given ptrSize
FuncPCABI0 returns the entry PC of the function f, which must be a
direct reference of a function defined as ABI0. Otherwise it is a
compile-time error.
Implemented as a compile intrinsic.
FuncPCABIInternal returns the entry PC of the function f. If f is a
direct reference of a function, it must be defined as ABIInternal.
Otherwise it is a compile-time error. If f is not a direct reference
of a defined function, it assumes that f is a func value. Otherwise
the behavior is undefined.
Implemented as a compile intrinsic.
IMethodSize returns sizeof(IMethod) for a compilation target with a given ptrSize
InitializedOffset returns a new Offset with specified offset, alignment, pointer size, and slice alignment.
KindOff returns the offset of Type.Kind_ for a compilation target with a given ptrSize
NewOffset returns a new Offset with offset 0 and alignment 1.
PtrBytes returns the offset of Type.PtrBytes for a compilation target with a given ptrSize
SizeOff returns the offset of Type.Size_ for a compilation target with a given ptrSize
StructFieldSize returns sizeof(StructField) for a compilation target with a given ptrSize
TFlagOff returns the offset of Type.TFlag for a compilation target with a given ptrSize
UncommonSize returns sizeof(UncommonType). This currently does not depend on ptrSize.
This exported function is in an internal package, so it may change to depend on ptrSize in the future.
addChecked returns p+x.
The whySafe string is ignored, so that the function still inlines
as efficiently as p+x, but all call sites should use the string to
record why the addition is safe, which is to say why the addition
does not cause x to advance to the very end of p's allocation
and therefore point incorrectly at the next block in memory.
Package-Level Constants (total 91, all are exported)
ArgsSizeUnknown is set in Func.argsize to mark all functions
whose argument size is unknown (C vararg functions, and
assembly code without an explicit specification).
This value is generated by the compiler, assembler, or linker.

FuncFlagAsm indicates that a function was implemented in assembly.
FuncFlagSPWrite indicates a function that writes an arbitrary value to SP
(any write other than adding or subtracting a constant amount).
The traceback routines cannot encode such changes into the
pcsp tables, so the function traceback cannot safely unwind past
SPWrite functions. Stopping at an SPWrite function is considered
to be an incomplete unwinding of the stack. In certain contexts
(in particular garbage collector stack scans) that is a fatal error.
FuncFlagTopFrame indicates a function that appears at the top of its stack.
The traceback routine stop at such a function and consider that a
successful, complete traversal of the stack.
Examples of TopFrame functions include goexit, which appears
at the top of a user goroutine stack, and mstart, which appears
at the top of a system goroutine stack.
Functions that need frames <= StackBig can assume that neither
SP-framesize nor stackGuard-StackSmall will underflow, and thus use a
more efficient check. In order to ensure this, StackBig must be <= the
size of the unmapped space at zero.
StackNosplitBase is the base maximum number of bytes that a chain of
NOSPLIT functions can use.
This value must be multiplied by the stack guard multiplier, so do not
use it directly. See runtime/stack.go:stackNosplit and
cmd/internal/objabi/stack.go:StackNosplit.
After a stack split check the SP is allowed to be StackSmall bytes below
the stack guard.
Functions that need frames <= StackSmall can perform the stack check
using a single comparison directly between the stack guard and the SP
because we ensure that StackSmall bytes of stack space are available
beyond the stack guard.
TFlagExtraStar means the name in the str field has an
extraneous '*' prefix. This is because for most types T in
a program, the type *T also exists and reusing the str data
saves binary size.
TFlagNamed means the type has a name.
TFlagRegularMemory means that equal and hash functions can treat
this type as a single region of t.size bytes.
TFlagUncommon means that there is a data with a type, UncommonType,
just beyond the shared-per-type common data. That is, the data
for struct types will store their UncommonType at one offset, the
data for interface types will store their UncommonType at a different
offset. UncommonType is always accessed via a pointer that is computed
using trust-us-we-are-the-implementors pointer arithmetic.
For example, if t.Kind() == Struct and t.tflag&TFlagUncommon != 0,
then t has UncommonType data and it can be accessed as:
type structTypeUncommon struct {
structType
u UncommonType
}
u := &(*structTypeUncommon)(unsafe.Pointer(t)).u
UnsafePointRestart1(2) apply on a sequence of instructions, within
which if an async preemption happens, we should back off the PC
to the start of the sequence when resuming.
We need two so we can distinguish the start/end of the sequence
in case that two sequences are next to each other.

Like UnsafePointRestart1, but back to function entry if async preempted.
