This makes the {code_size_estimate} computation explicit in the caller, and removes one of the two {NewNativeModule} constructors. It turns out that the calculation is totally off in the streaming calculation phase, since no function bodies have been parsed yet. So all {WasmFunction::code} fields are still empty, and we compute an estimate that is way too low. This CL prepares the actual fix for that (by computing a better estimate at specific call sites).

In the presence of default arguments, the body of the function gets wrapped into another block. This caused our trailing-range-after-return optimization to not apply, because the wrapper block had no source range assigned. This CL correctly assignes a source range to that block, which allows already present code to handle it correctly. Note that this is not a real coverage bug; we've just been reporting whitespace as uncovered. We're fixing it for consistency.

Lack of size information can cause debugging and observability tools to misbehave or to fail. We can see the size for all builtins is zero with objdump: $ objdump -t d8 | grep Builtins_ArgumentsAdaptorTrampoline 0000000001084a00 l F .text 0000000000000000 Builtins_ArgumentsAdaptorTrampoline ^ Size is zero Tools like bpftrace rely on the function size to guarantee a tracepoint is added within function boundaries. Without size information, those tools can't guarantee a tracepoint will be added safely. Add .size directive for each builtin function, as described in https://sourceware.org/binutils/docs-2.24/as/Size.html#Size, to fix this issue. We can see with objdump that the size is properly set: $ objdump -t d8 | grep Builtins_ArgumentsAdaptorTrampoline 00000000010bf820 l F .text 0000000000000140 Builtins_ArgumentsAdaptorTrampoline R=bmeurer@chromium.org, hpayer@chromium.org, verwaest@chromium.org, yangguo@chromium.org Change-Id: I4cd2b0a12b629498dd9d7465cc1002dda37028c7 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1898807 Commit-Queue: Jakob Gruber <jgruber@chromium.org> Reviewed-by:Benedikt Meurer <bmeurer@chromium.org> Reviewed-by:

Introduce new operator LoadTransform that holds a LoadTransformInfo param, which describes the kind of load (normal, unaligned, protected), and a transformation (splat or extend, signed or unsigned). We have a new method that a full decoder needs to implement, LoadTransform, which resuses the existing LoadType we have, but also takes a LoadTransform, to distinguish between splats and extends at the decoder level. This implements 4 out of the 10 suggested load splat/extend operations (to keep the cl smaller), and is also missing interpreter support (will be added in the future).
