Update tests to use the new compilation API + related fixes. Esp. get rid of PreCompile in tests, as it's going to be removed. Notes: - The new compilation API doesn't have a separate precompilation phase, so there is no separate way to check for errors except checking the compilation errors. Removed some tests which don't make sense any more. - test-api/Regress31661 didn't make sense as a regression test even before the compilation API changes, because Blink doesn't precompile this short scripts. So detecting this kind of errors (see crbug.com/31661 for more information) cannot rely on precompilation errors. - test-parsing/PreParserStrictOctal has nothing to do with PreParser, and the comment about "forcing preparsing" was just wrong. - test-api/PreCompile was supposed to test that "pre-compilation (aka preparsing) can be called without initializing the whole VM"; that's no longer true, since there's no separate precompilation step in the new compile API. There are other tests (test-parsing/DontRegressPreParserDataSizes) which ensure that we produce cached data. - Updated tests which test preparsing to use PreParser directly (not via the preparsing API). - In the new compilation API, the user doesn't need to deal with ScriptData ever. It's only used internally, and needed in tests that test internal aspects (e.g., modify the cached data before passing it back). - Some tests which used to test preparse + parse now test first time parse + second time parse, and had to be modified to ensure we don't hit the compilation cache.

Change ScriptCompiler::CompileOptions to allow for two 'cache' modes (parser or code) and to be explicit about cache consumption or production (rather than making presence of cached_data imply one or the other.) Also add a --cache flag to d8, to allow testing the functionality. ----------------------------- API change Reason: Currently, V8 supports a 'parser cache' for repeatedly executing the same script. We'd like to add a 2nd mode that would cache code, and would like to let the embedder decide which mode they chose (if any). Note: Previously, the 'use cached data' property was implied by the presence of the cached data itself. (That is, kNoCompileOptions and source->cached_data != NULL.) That is no longer sufficient, since the presence of data is no longer sufficient to determine /which kind/ of data is present. Changes from old behaviour: - If you previously didn't use caching, nothing changes. Example: v8::CompileUnbound(isolate, source, kNoCompileOptions); - If you previously used caching, it worked like this: - 1st run: v8::CompileUnbound(isolate, source, kProduceToCache); Then, source->cached_data would contain the data-to-be cached. This remains the same, except you need to tell V8 which type of data you want. v8::CompileUnbound(isolate, source, kProduceParserCache); - 2nd run: v8::CompileUnbound(isolate, source, kNoCompileOptions); with source->cached_data set to the data you received in the first run. This will now ignore the cached data, and you need to explicitly tell V8 to use it: v8::CompileUnbound(isolate, source, kConsumeParserCache); ----------------------------- BUG= R=marja@chromium.org, yangguo@chromium.org Review URL: https://codereview.chromium.org/389573006 git-svn-id: https://v8.googlecode.com/svn/branches/bleeding_edge@22431 ce2b1a6d-e550-0410-aec6-3dcde31c8c00

Notes: - The new compilation API doesn't have a separate precompilation phase, so there is no separate way to check for errors except checking the compilation errors. Removed some tests which don't make sense any more. - test-api/Regress31661 didn't make sense as a regression test even before the compilation API changes, because Blink doesn't precompile this short scripts. So detecting this kind of errors (see crbug.com/31661 for more information) cannot rely on precompilation errors. - test-parsing/PreParserStrictOctal has nothing to do with PreParser, and the comment about "forcing preparsing" was just wrong. - test-api/PreCompile was supposed to test that "pre-compilation (aka preparsing) can be called without initializing the whole VM"; that's no longer true, since there's no separate precompilation step in the new compile API. There are other tests (test-parsing/DontRegressPreParserDataSizes) which ensure that we produce cached data. - Updated tests which test preparsing to use PreParser directly (not via the preparsing API). - In the new compilation API, the user doesn't need to deal with ScriptData ever. It's only used internally, and needed in tests that test internal aspects (e.g., modify the cached data before passing it back). - Some tests which used to test preparse + parse now test first time parse + second time parse, and had to be modified to ensure we don't hit the compilation cache.

Update tests to use the new compilation API + related fixes. Esp. get rid of PreCompile in tests, as it's going to be removed.
