This samples module code sizes at GC time instead of during destruction. It hence makes sure that we also receive samples for long-lived modules which would otherwise die with the Isolate and never be finalized. Note that this approach is still biased and just a stop-gap until we have a sampling tick based on actual wall-clock time.

Instead of having a separate liftoff config, which is tested against the default (which currently means tier-up from liftoff to turbofan), just choose reasonable liftoff configs for the existing configs. 'ignition' now implies pure liftoff execution. 'ignition_turbo_opt' always compiles with turbofan. Other configs use the default (tier up).

Remove the function identifier field from SharedFunctionInfo. This field would store one of a) the function's inferred name, b) the "builtin function id", or c) debug info. We remove these in turn: a) The function's inferred name is available on the ScopeInfo, so like the start/end position we read it off either the ScopeInfo (for compiled functions) or the UncompiledData (for uncompiled functions). As a side-effect, now both UncompiledData and its subclass, UncompiledDataWithPreparsedScope, contain a pointer field. To keep BodyDescriptors manageable, we introduce a SubclassBodyDescriptor which effectively appends two BodyDescriptors together. b) The builtin function id is < 255, so we can steal a byte from expected no. of properies (also <255) and store these together. Eventually we want to get rid of this field and use the builtin ID, but this is pending JS builtin removal. As a side-effect, BuiltinFunctionId becomes an enum class (for better storage size guarantees). c) The debug info can hang off anything (since it stores the field it replaces), so we can attach it to the script field instead. This saves a word on compiled function (uncompiled functions unfortunately still have to store it in UncompiledData).

Leszek Swirski authored
Instead of looking up functions by their function literal id (which can be slow now that function id involves a linear search for compiled functions), we key the lookup by the function's start position. This means that the script+literal id swapping to find equivalent unchanged functions during constant pool patching no longer works -- we could replace it by fixing up the start position of the redundant new function, but instead we just build up a side-table mapping (new) start positions to function literal ids, and use that function literal id to find the old function in the script's SFI list.

Andreas Haas authored
The WebAssembly spec is not fully deterministic: the sign bit of NaN can be arbitrary. This sign bit can be observed by several WebAssembly opcodes. In the testcase the sign bit of NaN makes the difference between terminating code and an infinite loop. In the libfuzzer fuzzer we have to prevent infinite loops ourselves. At the moment we do this by only execute generated code of WebAssembly modules for which the interpretation of the code ends in a limited number of steps. With the non-determinism described above we cannot guarantee the absence of infinite loops with this method. Therefore we stop now to execute generated code of WebAssembly modules for which we observe possible non-determinism in the interpreter.

At the May 2018 TC39 meeting, they decided to rename Atomics.wake to Atomics.notify. This change adds Atomics.notify as an alias, but does not remove Atomics.wake, which will be removed later. This allows for embedders to use either name to prevent breaking tests. When the tests are switched over, we can remove Atomics.wake.

Leszek Swirski authored
For a script '()=>42', the anonymous arrow function has both start and end position the same as the script function itself. This causes issues when sorting the SourcePositionEvents of the function, in two ways: * If the start positions are the same, we should order by *furthest* end position to ensure the stack is in the right order * If both start and end are the same, we need to order by function literal id to make sure that start order and end order are inversed. Also, MapLiterals assumes that start+end position uniquely identifies a function, which is false in this case, so we process the top-level script function separately in MapLiterals.
