This was deleted in 5b2ab2f6, it seems only the first part of the condition should have been deleted. This changes (from the embedded builtins): movz x9, #0x2 cmp x9, x8 Back to: cmp x8, #0x2 This saves 0.29% in the embedded builtins size for a pointer-compression enabled arm64 build. Also a minor cleanup by removing the commutative boolean parameter and always commuting the FlagsContinuation. For a commutative operation the FlagsContinuation will stay the same.

Forge (Google3) can only run 64-bit executables. As Torque runs as part of the build process, we need a 32-bit "cross-compile" mode when we target 32-bit architectures. Note that this flag won't be needed in Chromium/V8 land, since we build V8 with the same bit width as the target architecture. This CL adds a new runtime flag to torque "-m32". When enabled, the flag forces 32-bit word sizes for various pointer/word sizes. By default, the host system sizes from {src/commons/globals.h} are used.

When we break on function entry, check whether the target function is being called from JS after entering V8 through V8's API. We implement this by keeping track of the stack height when we enter V8 through the API, and compare the caller JS frame's stack height with that.

This is another step towards considering the unoptimized frame size in stack checks within optimized code. With the changes in this CL, we now keep track of the maximal unoptimized frame size of the function that is currently being compiled. An optimized function may inline multiple unoptimized functions, so a single optimized frame can deopt to multiple frames. The real frame size thus differs in different parts of the optimized function. We only care about the maximal frame size, which we calculate conservatively as an over-approximation, and track in InstructionSelector::max_unoptimized_frame_height_ for now. In future work, this value will be passed on to codegen, where it will be applied as an offset to the stack pointer during the stack check. (The motivation behind this is to avoid stack overflows through deopts, caused by size differences between optimized and unoptimized frames.) Note that this offset only ensure that the topmost optimized frame can deopt without overflowing the stack limit. That's fine, because we only deopt optimized frames one at a time. Other (non-topmost) frames are only deoptimized once they are returned to. Drive-by: Print variable and total frame height in --trace-deopt.

The LinkageLocation currently consists of two fields, a bit_field and a machine_type. The existing equality check only checked the equality of the bit_field, which meant that a FP register location and a GP register location could alias. I added a static {IsSameLocation} function which checks that not just the bit_field but also if one of the two locations at least has a subtype of the other. Note that we do not check for type-equality because {CanTailCall} checks, which are the main user of the LinkageLocation equality check, should pass even if the result types are in a sub-typing relationship.

This CL consists of several preparatory steps for slices in Torque. Above all, it introduces a user-defined struct, torque_internal::Slice<T>, that performs bounds checking and returns references to elements in arrays. To enable this, several smaller changes were also made: - Constructors of internal classes such as torque_internal::Reference<T> now require a special 'Unsafe' argument, making it clear that there be dragons. - Struct methods are now declared during finalization. This allows instances of generic structs to have methods referring to the same struct. Previously, methods would be declared before the instance had been fully registered, leading to errors during type resolution. Furthermore, such methods were declared in a temporary namespace, that would then erroneously escape and lead to use-after-free issues. - Instances of TypeArgumentInference were not running in the correct (Torque) scopes, leading to type resolution errors. - The chain of ContextualVariable::Scope for any given ContextualVariable (such as CurrentScope) can now be walked, simplifying debugging.
