Dear all, Hi! My name is Abe. I work in a part of Samsung the mission of which is to make Open Source compilers better. It`s a wonderful job.
What I would like to do with V8 -- and have not yet been able to figure out how -- is to have it parse and compile the JS code it receives, *not* execute that code, and profile the compilation time. In other words, to pretend that V8 is a “normal” compiler like GCC`s C compiler, and to profile V8 as such. If I understand correctly, recent V8 releases have 3 compilers: * full-codegen * Crankshaft * TurboFan Have I understood correctly, or is the preceding the result of mentally merging documentation from different V8 releases in a way that doesn`t correspond to the real world? Ideally, I would like to be able to invoke V8 ‘c•f’ times, where ‘c’ is the # of compilers V8 has inside and ‘f’ is the # of JS source files I am processing [my first choice is to use the Octane benchmark suite]. For each invocation, I want the compiler to compile *all *the functions in the code, without actually executing any of it, and to profile the invocation, preferably with somewhat-fine-grained statistics, e.g. with time to parse reported separately from time to compile. I realize that at least *some* of the above is already provided by the profiling-related and tracing-related options to “d8” and friends, but it seems to me that what`s already there [at least in version 4.9.167, which was released on Dec. 7 2015] is not enough to get it all done. As a temporary work-around, I would call it major progress if I could do all of the above with the exception of the “without executing the code” part. I realize that this is a challenge for an implementation of a very dynamic language, especially one in which function definition is not necessarily done statically. Can any of the above be done at all without writing a new C++ program that uses V8 as a library? If so, then how, please?
