Compiles a particular permutation, based on a precompiled unified AST.

Parameters:

logger - the logger to use

compilerContext - shared read only compiler state

unifiedAst - of stitched together per-type ASTs

permutation - the permutation to compile

Returns:

the output JavaScript

Throws:

UnableToCompleteException - if an error other than OutOfMemoryError occurs

Performs a precompilation, returning a unified AST.

Parameters:

logger - the logger to use

compilerContext - shared read only compiler state

rpo - the RebindPermutationOracle

declEntryPts - the set of entry classes declared in a GWT module; these will be automatically rebound

additionalRootTypes - additional classes that should serve as code roots; will not be rebound; may be null

singlePermutation - if true, do not pre-optimize the resulting AST or allow serialization of the result

precompilationMetrics - if not null, gather diagnostic information from this build for a report.

Returns:

the unified AST used to drive permutation compiles

Throws:

UnableToCompleteException - if an error other than OutOfMemoryError occurs
