The existing signature is problematic for two reasons: 1. The void* -> V cast is invalid if sizeof(V) < sizeof(void*) 2. It's impossible to distinguish between a returned value of 0 and nullptr, designating failure.

To implement builtin continuations called from the deoptimizer, we need to better support writing builtins declared with javascript binding in Torque. This CL adds fixed number of argument support. So you can declare in Torque, something like: builtin javascript Foo(context: Context, receiver: Object, bar: Object): Object { ... } Formerly, this would give you an error because we only supported javascript bindings with a varargs array.

Instead of passing multiple pointers to input and output, or to two input values, just pass one pointer which holds all inputs and where the output is written. This also reduces the size of generated Turbofan graphs, since only one stack slot is needed and less arguments are passed to the call. It also fixes undefined behaviour, since we were passing a pointer e.g. as {uint64_t*}, but accessed it using {ReadUnalignedValue}. Now we pass an Address, which does not have any alignment constraints.

The memory metric samples memory usage immediately after forcing GC via LowMemoryNotification. This makes the metric sensitive to the unmapper tasks timing. This patch forces eager unmapping in CollectAllAvailableGarbage. It also forces eager unmapping of non-regular chunks at the beginning of Mark-Compact to avoid accumulation of non-regular chunks.

This refactoring is a big step towards separating Turbofan-related code from backend independent code. This will allow us to include way less headers from "src/compiler" at various places. The {WasmCompilationUnit} contained information for Turbofan compilation, and for Liftoff compilation. This CL tears this apart, such that {WasmCompilationUnit} holds backend-independent information, plus a pointer to either {LiftoffCompilationUnit} or {TurbofanWasmCompilationUnit}. These pointers are opaque, so that {function-compiler.h}, defining {WasmCompilationUnit}, does not need to include any Turbofan specific or Liftoff specific headers.

The Cvtqui2ss and Cvtqui2sd methods did overwrite the {src} register and the given {tmp} register. This CL fixes this to avoid the overwrite of the {src} register, and to use the kScratchRegister instead of an explicitly passed tmp register. It also adds u32 -> f32/f64 conversions. All these methods can take either a register or an operand as src. This sometimes saves a mov operation.

Calls to madvise(MADV_FREE_REUSABLE) [when discarding/decommitting memory] should be paired with calls to madvise(MADV_FREE_REUSE) [when reusing/committing memory]. The latter is purely for accounting purposes.

This turns most DCHECKs in the register allocator code into CHECKs, which hopefully will tell us more about the crashes in crbug 831822. This CL will eventually be reverted again.

Previously when we put offsets into the SourcePositionTable, we added the header size of the code object as well. When we pull the positions out of the table (see ProfileGenerator::RecordTickSample) we already account for the header size. This means the offsets in the table should just be the offset of the PC within the actual code, not the offset within the code object, which is what we currently store. Currently this bug is probably not very noticeable, as it causes the reported line numbers to be slightly too low, but still within the same function. For a sampling profiler, we don't have any way to confirm which lines were actually sampled, so we don't notice that the results are wrong. The only way to see this bug is that there are some lines within a function (towards the end of the function) that we will never see ticks inside of, because the offset in the position table is not reachable with valid PC offsets. This CL removes the header size offset from values put into the source position table stored by the profiler.
