Compilation filter
This CL introduces a static compilation filter mechanism intended
to allow us to reduce compilation time and space requirements until
we have a profiling mechanism in place.
It supports 5 modes of filtering:
o interpret-only (compile nothing)
o deferred-compilation (compile only those methods believe to be
compute-intensive)
o space (optimized for space)
o balanced (best return on space investment)
o speed (compile everything)
A future CL will allow the default filtering mode to be set
via system property. For now, you can pass it in via command
line as follows:
dalvikvm -compiler-filter:[interpret-only|defer-compilation|
space|balanced|speed]
or dex2oat --runtime-arg -compiler-filter:[one of the above modes]
Creating a file named art/SMALL_ART will force the filter
default to interpret-only. Later on we'll move this capability
to a persistent system property.
or modify kDefaultCompilerFilter in runtime.h
It also changes the compiler driver to allow the compilers to
decline to compile a method by return NULL.
