Summary: modify SWF9Writer to pass smaller chunks of javascript to script
compiler

Overview:
For swf10 compiles, instead of building one large javascript string
and passing it to the script compiler, this sends each chunk of script
that is passed to a persistent instance of the script compiler.
Calls to CompilationEnvironemnt.compileScript (hence to SWF9Writer.addScript)
are sent down to a new "compileBlock" method in sc.Compiler.
Details:
This implements a new subclass of sc.Compiler, sc.SWF10Compiler.
Instead of a monolithic call to sc.Compiler.compile(), a SWF10 compile
is initialized with a call to
sc.SWF10Compiler.startSWF10App()
then blocks of script are compiled via calls to compileBlock()
and the finalization is done with a call to finishSWF10App(). This
creates any needed interstitials and global var declarations, as well
as the main app boilerplate.
The flex compiler is then called.
+ SWF9Generator has some things refactored into new methods:
makeInterstitials()
writeGlobalTUnitsToAS3()
writeMainTranslationUnit()
callFlexCompiler()
- a persistent pointer to a script parser and to the "main translation unit" is
kept around so that
it can be reused for each call to compileBlock().
- the "classes" table, which kept a copy of all class defs in order to create
interstitials,
is now called "classConstructors", and only keeps a copy of the AST subtree
that is the class
constructor. The tree is diked out of it's parent using the deepCopy method.
Tests:
smokecheck, lzpix, test/snippets/import-class-and-view.lzx
A compile of the customer app now requires about 200-400 MB less of memory.
The app can be compiled in non-debug mode with 640MB max heap (down from 800MB)
In backtrace mode, it requires 1000MB max heap (down from 1400MB).
