|scope_snapshot_| might not have been cleared if there was a parser error between setting the snapshot and consuming it. Explicitly clear it at the end of parsing for that case. Otherwise Scope::Snapshot's destructor will possibly write into the already freed zone.

Swaps around the checks in CompileLazy to ensure we always enter the runtime to lazy compile if a function's SFI is uncompiled. This is necessary with bytecode flushing since the function may have an optimized code marker in the feedback vector, even if the bytecode has been flushed, and we don't want to try to optimize this flushed function.

This CL marks v8::Isolate::GetEnteredContext as deprecated in favor of replacing it with GetEnteredOrMicrotaskContext. Blink no longer uses it, and Node.js does not use this too. GetEnteredOrMicrotaskContext() is relevant for all known cases over GetEnteredContext(), and it costs 2% of a benchmark score to maintain the entered contexts under the nestable microtask context. https://crrev.com/c/1322290 is a context for the bencmark and nestable microtask contexts.

This makes changes to the generic code in Liftoff to support f32 values on the arm32 port, but does not implement any handling of them in practice.

This reduces wasm's ABI on Arm to only using the even-numbered float registers in anticipation of Liftoff supporting f32 values on the arm32 port. This is due to Liftoff assuming a one-to-one mapping between double and float registers. The ABI must be restricted in order to allow Liftoff compiled and Turbofan compiled functions to call each other. Turbofan continues to use all float registers internally however.

This reverts commit d5f4a33e. Reason for revert: Seems to cause a no snapshot build failure - https://ci.chromium.org/p/v8/builders/luci.v8.ci/V8%20Linux%20-%20nosnap%20-%20debug/21967 Original change's description: > [cpu-profiler] Fix stack iterability for fast C calls with no exit frame > > Before fast C calls, store the current FP and PC on the isolate. When > iterating frames in SafeStackFrameIterator, check if these fields are > set and start iterating at the calling frame's FP instead of the current > FP, which will be in C++ code. We need to do this because c_entry_fp is > not set on the Isolate for Fast-C-Calls because we don't build an exit > frame. > > This change makes stack samples that occur within 'Fast-C-Calls' > iterable, meaning we can properly attribute ticks within the JS caller. > > Fast-C-Calls can't call back into JS code, so we can only ever have one > such call on the stack at a time, allowing us to store the FP on the > isolate rather than the stack. > > TBR=v8-mips-ports@googlegroups.com > > Bug: v8:8464, v8:7202 > Change-Id: I7bf39eba779dad34754d5759d741c421b362a406 > Reviewed-on: https://chromium-review.googlesource.com/c/1340241 > Commit-Queue: Peter Marshall <petermarshall@chromium.org> > Reviewed-by: Jakob Gruber <jgruber@chromium.org> > Reviewed-by: Martyn Capewell <martyn.capewell@arm.com> > Reviewed-by: Alexei Filippov <alph@chromium.org> > Cr-Commit-Position: refs/heads/master@{#57896} TBR=alph@chromium.org,jgruber@chromium.org,petermarshall@chromium.org,martyn.capewell@arm.com,v8-arm-ports@googlegroups.com,v8-mips-ports@googlegroups.com,ibogosavljevic@wavecomp.com Change-Id: I85f846e57b6fa845e7770c616435cebffdb2a245 No-Presubmit: true No-Tree-Checks: true No-Try: true Bug: v8:8464, v8:7202 Reviewed-on: https://chromium-review.googlesource.com/c/1352302Reviewed-by:
