The jump optimization maybe run Turbofan pipeline twice for each TF/CS builtins, and relies on the fact that the number of j/jmp instruction generated is always the same. This CL introduces a verification process to ensure that instruction sequence and virtual registers are always the same in two stages, before the final code generation phase.

This CL moves the remaining runtime DataView getters to Torque, namely DataViewGetBigInt64/BigUint64, and removes the associated runtime code that is now unneeded. All of the DataView getters are now implemented in Torque, which brings a nice performance improvement over the former C++ builtin code.

For kUpdateEntry and kRemoveEntry, the ArrayBuffer is no longer present on the current page. These are the two most common cases; kKeepEntry is only used for aborted old-page evacuation candidates. Currently we pay the cost of removing the entry from the array_buffers_ map, even though the page itself will be cleared (for new space) or only aborted evacuation candidates will be kept on the page (for old space).

jgruber authored
The stack check instruction sequence is pattern-matched in instruction-selector-{ia32,x64}.cc and replaced with its own specialized opcode, for which we later generate an efficient stack check in a single instruction. But this pattern matching has never worked for CSA-generated code. The matcher expected LoadStackPointer in the right operand and the external reference load in the left operand. CSA generated exactly vice-versa. This CL does a few things; it 1. reverts the recent change to load the limit from smi roots: Revert "[csa] Load the stack limit from smi roots" This reverts commit 507c29c9. 2. tweaks the CSA instruction sequence to output what the matcher expects. 3. refactors stack check matching into a new StackCheckMatcher class. 4. typifies CSA::PerformStackCheck as a drive-by.
