Reviewers: fschneider,
Message:
A later change will change all the CodeGenerator:: binary operation
implementations to take an AST BinaryOperation node, rather than passing
all the
information as separate parameters.
Description:
Add static analysis to AST expressions that records whether a negative zero
will
be treated identically to a positive zero in the expression's context. Use
this
flag to avoid some tests in inlined smi code.
