Both `sizeOf` and `AllocatorAlloc.call` use the new type as bound.
This prevents runtime errors on trying to call these two static
methods with unsized native types. All tests testing for these runtime
errors have been deleted.
The `NativeTypes` implementing `SizedNativeType` are as follows:
* The native integer types, `Float`, and `Double`.
* `AbiSpecificInteger` and it's subtypes.
* `Struct` and `Union` and their subtypes. The
The `NativeTypes` not implementing `SizedNativeType` are as follows:
* `Void` has no size.
* `Opaque` and subtypes have unknown size.
* `Handle` is considered opaque. Cannot be used as field in compounds.
* `Array` does not carry a size in its type. Can be used as fields in
compounds with an annotation specifying the size.
* `NativeFunction` is considered opaque. Would have variable size.
* `VarArgs` is only a marker in function signatures.
`Struct`s and `Union`s can have only `SizedNativeType`s and `Array`s
as fields. Documentation for these is in flux in another CL, so we
should update it there.
This CL also replaces a bunch of `extends NativeType` with
`implements` clauses and made `NativeType` itself `abstract`.

This CL introduces `VarArgs` to `NativeFunction` signatures. The
`VarArgs` type takes a single type argument. This type argument is a
subtype of `NativeType` if there is a single variadic argument, and a
record with native types if there are multiple variadic arguments.
For example:
`NativeFunction<Void Function(Pointer<Char>, VarArgs<(Int32,Int32)>)>`
for calling refering to a `printf` binding with two `int32_t` arguments
passed as variadic arguments.
The logic of the native calling conventions are detailed in
https://dart-review.googlesource.com/c/sdk/+/278342.
Here we explain how this influences the FFI pipeline.
First, now that `VarArgs` is part of signatures, we have to unwrap
that when with the C types in the CFE transform and checking (analyzer
is in a separate CL), and also in the marshaller when looking up the
C type of arguments.
Second, we have to deal with `BothNativeLocations`. On windows x64,
floating point arguments must be passed both in FPU _and_ CPU
registers. For FFI calls, we solve this in the argument moves by just
copying to both locations. For FFI callbacks, we just take the FPU
register location (which avoids an extra bitcast).
Third, on System-V, we have to pass an upper bound of the number of
XMM registers used in AL. This means we instead RAX, we use R13 for the
target address. For variadic calls, we always pass 8 in AL as the valid
upper bound. We could consider passing the actual number of XMM
registers used.
We keep using RAX as default register for the function address on non-
variadic calls, because changing to R13 (the first free) register
creates more spilling in leaf calls. R13 is callee-saved while RAX is
not, so using R13 instead of RAX causes us to have to spill the value
from RAX on leaf calls.
Fourth, on both x64 and RISC-V, we pass floats in integer locations.
`EmitNativeMove` has been modified to deal with this, so that we do not
have to insert more `BitCastInstr`s.
The tests are generated by a test generator: `tests/ffi/generator/`.
The formatter doesn't support records yet, so the tests are not properly
formatted.

We're adding these types to `dart:ffi` rather than `package:ffi` so that
they can be used with `FfiNative`s.

* short

* int

even if all current target platforms agree on the size.

Implements a backend targeting RV32GC and RV64GC, based on Linux standardizing around GC. The assembler is written to make it easy to disable usage of C, but because the sizes of some instruction sequences are compile-time constants, an additional build configuration would need to be defined to make use of it.
The assembler and disassembler cover every RV32/64GC instruction. The simulator covers all instructions except accessing CSRs and the floating point state accessible through such, include accrued exceptions and dynamic rounding mode.
Quirks:
- RISC-V is a compare-and-branch architecture, but some existing "architecture-independent" parts of the Dart compiler assume a condition code architecture. To avoid rewriting these parts, we use a peephole in the assembler to map to compare-and-branch. See Assembler::BranchIf. Luckily nothing depended on taking multiple branches on the same condition code set.
- There are no hardware overflow checks, so we must use Hacker's Delight style software checks. Often these are very cheap: if the sign of one operand is known, a single branch is needed.
- The ranges of RISC-V branches and jumps are such that we use 3 levels of generation for forward branches, instead of the 2 levels of near and far branches used on ARM[64]. Nearly all code is handled by the first two levels with 20-bits of range, with enormous regex matchers triggering the third level that uses aupic+jalr to get 32-bits of range.
- For PC-relative calls in AOT, we always generate auipc+jalr pairs with 32-bits of range, so we never generate trampolines.
- Only a subset of registers are available in some compressed instructions, so we assign the most popular uses to these registers. In particular, THR, TMP[2], CODE and PP. This has the effect of assigning CODE and PP to volatile registers in the C calling convention, whereas they are assigned preserved registers on the other architectures. As on ARM64, PP is untagged; this is so short indices can be accessed with a compressed instruction.
- There are no push or pop instructions, so combining pushes and pops is preferred so we can update SP once.
- The C calling convention has a strongly aligned stack, but unlike on ARM64 we don't need to use an alternate stack pointer. The author ensured language was added to the RISC-V psABI making the OS responsible for realigning the stack pointer for signal handlers, allowing Dart to leave the stack pointer misaligned from the C calling convention's point of view until a foreign call.
- We don't bother with the link register tracking done on ARM[64]. Instead we make use of an alternate link register to avoid inline spilling in the write barrier.
Unimplemented:
- non-trivial FFI cases
- Compressed pointers - No intention to implement.
- Unboxed SIMD - We might make use of the V extension registers when the V extension is ratified.
- BigInt intrinsics

This CL adds the `Bool` `NativeType` with support for loading/storing
from `Pointer<Bool>`, `Array<Bool>`, and `Struct` and `Union` fields,
and support for passing booleans through FFI calls and callbacks.
The assumption is that `bool` is always treated as `uint8_t` in the
native ABIs. Including: (1) whether there can be garbage in the upper
bytes in CPU registers, (2) stack alignment, and (3) alignment in
compounds.
The conversion from `bool` to `uint8_t` is implemented as follows:
- bool to int: `value ? 1 : 0`
- int to bool: `value != 0`
The conversion is implemented in Dart in patch files for memory loads
and stores (pointer, array, and struct fields) and kernel_to_il for
FFI call and callback arguments and return value.

Move the nnbd core libraries from sdk_nnbd to sdk, and updates
references in build files and elsewhere accordingly.

This includes support for calling Dart_PropagateError in native code
when doing FFI calls, and catching uncaught exceptions with Dart_IsError
when doing FFI callbacks.
The support for Dart_PropagateError adds a catch entry to the FFI
trampoline, which prevents inlining these trampolines in AOT. This
regresses the FfiCall benchmarks by 1-2% in AOT.
In addition, Dart_PropagateError requires maintaining a bit whether we
entered native/VM code from generated code through FFI or not. That way
we can do the proper transition on the exception path. When entering
generated code, we store this bit on the stack, right after the entry
frame.

This is practically a copy of the change in
https://dart-review.googlesource.com/c/sdk/+/118040 but applied to the non-nnbd
sdk.
Even though there is no intent to run the non-nnbd sdk with the non-nullable
experiment, we need to add this annotation because of how we
intend to gradually start testing NNBD. The libraries.json under
sdk_nnbd is allowed to point to libraries under the non-nnbd sdk in order to
temporarily build without errors until all patch files are migrated and all CFE
issues are addressed.

NativeFunction was not handled despite being concrete. We can just make it (and Void) abstract
because they cannot appear directly as the type of native field, only as a type argument.
