Detailed Description

QQmlJSTypePropagator is the initial pass that performs the type inference and annotates every register in use at any instruction with the possible types it may hold. This includes information on how and in what scope the values are retrieved. These annotations may be used by further compile passes for refinement or code generation.

As far as type propagation is involved, StoreNameSloppy and StoreNameStrict are completely the same StoreNameStrict is rejecting a few writes (where the variable was not defined before) that would work in a sloppy context in JS, but the compiler would always reject this. And for type propagation, this does not matter at all. nameIndex is the index in the string table corresponding to the name which we are storing

mergeRegister()

void QQmlJSTypePropagator::mergeRegister ( int index, const VirtualRegister & a, const VirtualRegister & b )

protected

Merges the types of two variations of the register at \index When the code branches and merges, the same register can carry one of multiple types. For example:

let a if (something) a = 12 else a = "stringstring" console.log(a)

At the point where we log the value we need a type that can hold both, the number and the string because we don't know which branch was taken before. mergeRegister chooses a type that can hold both variants.

Since the type propagator can run multiple passes over the same code (for loops with back jumps), we need to reproduce previous resolutions of the merge where they still fit. To that effect, we check m_prevStateAnnotations here.
