The flag should not be set after an exception is thrown in a runtime function. The unwinder still runs after the destructor, and should take care of setting the flag depending on the catching frame.

Follow-up from https://crrev.com/c/2649147/.

This change adds a new abstract type Lazy<T> which can be used to interoperate with CSA code that uses LazyNode. This new type has special code-generation rules because its generated type is not TNode<...> but std::function<TNode<...>()>. Torque code can do nothing with this type except pass it around, but passing it to the CSA function RunLazy is an easy way to execute the std::function and get back a normal value. Torque code can also create Lazy<T> values using the intrinsic function %MakeLazy, which takes the name of a macro as its first parameter, followed by arguments to that macro which will be passed when the LazyNode is evaluated. We use the macro's name because the language doesn't support taking references to macros, and implementing such a feature would be complicated.

Mike Stanton authored
When making inlining decisions, we are interested in CodeRef::inlined_bytecode_size(). Previously, we gated a check of this value on predicate JSFunctionRef::HasAttachedOptimizedCode(), but we removed this predicate because it only recorded a value seen at serialization time. Now, we look at attached CodeRefs "live," which means we might discover that the code is now optimized, where it wasn't at serialization time. This affects the inlining decision. This CL adds an additional check before returning a non-zero inlined_bytecode_size that the code object hasn't (already) been deoptimized. It's logical to do this, because the inlined_bytecode_size is actually a stale value at this point.

This avoids having to check both flags in two places, and prevents people from trying to enable WebAssembly in lite mode (which would currently build, but you still would not get Wasm support). The downside is that the default value shown by `gn args --list` now sais `""` instead of `true`.

Georg Neis authored
AbstractBytecodeArray was introduced in order to let the bytecode array accessor work on either a Handle<BytecodeArray> or a serialized BytecodeArrayRef. We have since implemented direct heap access for bytecode arrays, so we can now remove the abstraction again. Note that this means that as far as bytecode iteration is concerned we no longer access the bytecode array through the BytecodeArrayRef. I will remove the obsolete methods from that class in a follow-up CL. The downside is the loss of this explicit interface. The upside is simplicity and less code. We can justify the downside with the fact that the bytecode array data is immutable and thus the Ref indirection less meaningful than in other cases.

If two call instructions were generated right after each other, the source position table could get populated with two entries for the same PC (triggered by the follow-up CL: https://crrev.com/c/2697359). This CL fixes that by slightly changing the carry-over of source positions from nodes to instructions. The call node which has a source position attached generates two instructions: 18: gap () ([rax|R|tp] = v16(-); [rbx|R|t] = v17(-);) [rax|R|t] = ArchCallWasmFunction [immediate:4] #-1 [rax|R|tp] [rbx|R|t] [immediate:5] 19: gap () () ArchJmp [immediate:6] Those are then reversed, and the source position is attached to the first one (the ArchJmp). After reversing it again later, the source position will be set to the pc *after* the call instruction, which in the example happened to be just another call instruction which already had a source position, resulting in this code: [...] 0x388ee467d426 66 e875feffff call 0x388ee467d2a0 ;; wasm stub: WasmThrow 0x388ee467d42b 6b e850feffff call 0x388ee467d280 ;; wasm stub: WasmStackGuard [...] Source positions: pc offset position 6b 5 6b 0 By attaching the source position to the *last* instruction (after reversing), we ensure that it will be generated for an instruction *before* the call, or the call itself if this is the first instruction emitted for that node.

Load lanes require that dst == src1 when AVX is not supported, add that constraint to the instruction selector. For Liftoff, we change the macro defintions of Movlps and Movhps to do the move if dst != src1.

This reverts commit 0818d138. Reason for revert: Rolling back to previous greedy slot allocator. tbr=ahaas@chromium.org Original change's description: > [compiler][wasm] Fix Wasm linkage > > - Fixes a problem when constructing Wasm CallDescriptors, where the > allocation tries to treat parameters and returns as if they are in the > same frame. This doesn't work when slots may be aligned in their > frame. Instead, allocate parameters and returns separately and offset > return slots by the number of parameter slots. > - Adds argument slot padding in the CallDescriptor lowering case, to > prepare for when 32 bit targets align stack frames and require > padding. > - Adds a regression test. > > Bug: chromium:1174500 > Change-Id: I60d96a94b171a0d27ff61cbab35623976b0c6da8 > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2683024 > Commit-Queue: Bill Budge <bbudge@chromium.org> > Reviewed-by: Andreas Haas <ahaas@chromium.org> > Cr-Commit-Position: refs/heads/master@{#72588} Bug: chromium:1174500 Change-Id: I1d1c389acde43bd56e6d2a27e1a3eb8ea4d6073c Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2713206 Bot-Commit: Rubber Stamper <rubber-stamper@appspot.gserviceaccount.com> Reviewed-by:
