The second argument of FromParameterIndex should be the parameter count, including the receiver. Previously it worked by chance, because the code was trying to access the receiver but did not include it in the parameter count, accessing the first argument. This does not work anymore when the arguments are reversed (V8_REVERSE_JSARGS).

Goal is to include coverage of builtin functions into coverage bitmap send to Fuzzilli fuzzer. In order to do this, after each REPRL loop, coverage data of bitmaps are retrieved from JS heap and stored into coverage bitmap. Additionally, there is an option, to print out statistics about how many of edges from builtin functions were turned on by the program inputted into REPRL loop. This commit introduces two flags: --no-fuzzilli-enable-builtins-coverage - when enable-builtins-coverage turned of, builtins coverage will not be exported to fuzzilli --fuzzilli-coverage-statistics - when turned on, d8 prints statistics into covlog.txt file after each loop Change-Id: I8f9cf8dc693b952467b108c6d6bc00134125bc5f Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2263154 Commit-Queue: Peter Ralbovsky <ralbovsky@google.com> Reviewed-by:

Instead of having one method with a big switch, and specializing that method for each single opcode, we now have one proper method per opcode. This makes the code way more readable, and also reduces the compile time of liftoff-compiler.cc significantly. Unfortunately, we cannot use template specializations for this, since GCC does not support specializing the methods within an unspecialized templated class. Hence, we need to have another dispatch per opcode when generating the opcode handler table. I left a comment explaining why we do it this way. The upside of this is that we get nicer method names.

Native context independent code generation should, at the moment, not use any collected feedback. We implement this by returning InsufficientFeedback from the heap broker's ReadFeedbackForX methods if currently compiling nci code. Thus all feedback.IsInsufficient() calls inside the compiler will return true (disabling feedback-based optimizations). FeedbackSource::IsValid() (used in generic lowering) can still return true.

Turbofan now has support for generating generic code in two variants, with and without feedback collection. Currently, feedback is collected only for some load and store operators (historical reasons). This CL enables feedback collection for (almost) all operators by default. The exception in the default TF configuration are call and construct variants (see also https://crrev.com/c/2276042). In NCI mode, all operators collect feedback. Regression have looked acceptable in our benchmarks so far. This is an experiment to see impact on real world. If successful, the non-collecting variants can be removed.
