This turns the deoptimization entries from free-floating memory chunks that were not considered part of the heap into true {Code} objects. By marking them as immovable we get the same guarantees without the need for side-stepping heap API methods.

This was originally introduced to reuse large handlers, but now only LdaContextSlot and LdaCurrentContextSlot remain (both roughly 2-300 bytes in size). Since handler reuse complicates lazy (de)serialization and currently doesn't seem to give us significant advantages, let's remove this.

Karl Schimpf authored
Like CSP flag 'unsafe-eval', which communicates if both JS source files and WASM binary files may be compiled, this CL adds a similar flag for the compilation of WASM binary files. That is, a WASM binary file will be compiled only if the new flag is defined, or the flag for 'unsafe-eval' allows it. These flags are implemented as callback functions on the isolate. The callbacks get a (CSP) context, and a string, and returns the corresponding value of the flag. Both callbacks are initialized with the nullptr, and is used to communicate that no CSP policy is defined. This allows this concept to work, independent of it running in Chrome. It also does a small clean up in api.cc to use macro CALLER_SETTERS, instead of explicit code when appropriate.

The Wasm AST-based fuzzer is supposed to create valid modules by construction. This change adds a CHECK to enforce this property. Additionally, this change exposed several cases where we were not generating valid modules before: * Block types did not match up correctly * Memory operations could have invalid alignments * Storing an i64 could generate an i32 argument incorrectly. This CL includes fixes for these issues as well.

Function prologues created slots for callee-saved registers twice on all platforms. This didn't affect JS because it doesn't use callee-save, but would probably have badly broken exceptions raised in Wasm code because Isolate::UnwindAndFindHandler was restoring registers and SP incorrectly. It also broke the in-progress CL for on-stack multiple returns. No tests included with this fix, because currently it is almost impossible to test directly (according to mstarzinger). But it will be tested indirectly via the upcoming multi-return support. Change-Id: If763cafc03de0a912eca48d5e25e8edfc4552b24 Reviewed-on: https://chromium-review.googlesource.com/758374Reviewed-by:

For each single bug, the fuzzer might find many very similar inputs which trigger this bug. All of them are reported as individual bugs currently, which means lots of noise in bug reports and increased workload for the clusterfuzz sheriffs. After this change, all bugs of the same category ("compiles != validates", "interpreter != liftoff", ...) will be grouped together. This requires us to fix them soon after reporting, as they will hide all other bugs of the same category.

There's three common situations in which we need to create JSFunction objects. 1) from the compiler, 2) from tests, and 3) everything else (mostly during bootstrapping). This is an attempt to simplify case 3), which previously relied on several Factory::NewFunction overloads where it was not clear how the semantics of each overload differed. This CL removes all but one overload, and packs arguments into a new NewFunctionArgs helper class. It also removes the hacks around SFI::set_lazy_deserialization_builtin_id by explicitly passing builtin_id into Factory::NewSharedFunctionInfo.
