Split out libplatform into a separate libary · ca16bb7a

jochen@chromium.org authored Jul 03, 2014

Also remove the "use default platform" compile flag. Instead, the embedder
has to provide the platform.

Change all binaries to use the default platfrom from libplatform.

Unless --job-based-sweeping is passed, nothing uses the platform yet, so
nothing will break for embedders (yet).

Revert "Remove special ExecutableAccessorInfo handling based on flag" · a1dd1a26

verwaest@chromium.org authored Jul 02, 2014

Temporarily reverting until we figure out how to handle the API cases that use accessors to lazily compute values.
dataAttributeGetterCustom in V8MessageEventCustom (at least) overwrites itself with the computed value using ForceSet. We can either force such clients to first use ForceDelete before caching, use some other caching mechanism; or provide an API for lazily computed properties.
