Bug 156941 – Renaming SpecInt32, SpecInt52, MachineInt to SpecInt32Only, SpecInt52Only, AnyInt.

• Component: JavaScriptCore
• Status: RESOLVED FIXED

[Mark Lam]

While looking at https://bugs.webkit.org/show_bug.cgi?id=153431, it was decided that SpecInt32Only, SpecInt52Only, and AnyInt would be better names for SpecInt32, SpecInt52, and MachineInt.  Let's do a bulk rename.

It's a shame that this is called AnyInt while we have:

> Source/JavaScriptCore/bytecode/SpeculatedType.h:72
>  static const SpeculatedType SpecInt52AsDouble      = 1u << 24; // It's definitely an Int52 and it's inside a double.

Under the new nomenclature, this should be called SpecAnyIntAsDouble.

> Source/JavaScriptCore/bytecode/SpeculatedType.h:73
> +static const SpeculatedType SpecInteger            = SpecAnyInt | SpecInt52AsDouble; // It's definitely some kind of integer.

And this.

I think this is why the other one was called MachineInt.  Looking at the code, it seems that SpecInteger is used only in one place.  We could just remove SpecInteger and replace its one use with "SpecAnyInt | SpecAnyIntAsDouble"
