      [wasm] [asm.js] Track direct function indices and fixup. · cfed56c2
      bradnelson authored 
      Recent changes to the wasm format prevent you from knowing
the function index of a direct call until you know how many
imports you have (the index spaces have been merged).

Asm.js validation can't know this until all callsites have been
visited if you want to avoid materializing the entire AST / parsing twice.
Instead, keep a list of fixups to perform for all direct callsites,
then update these with the imports count added when emitting the module.

      [wasm] cleanup wasm-module.cc · 55478da2
      mtrofin authored 
      - Coalesced all anonymous namespaces into one, and moved it to the
top of the file, to match elsewhere in the v8 codebase.
- Deleted dead code.
- Moved functions that turned out to be local to wasm-module.cc to
the anonymous namespace.

      [wasm] Do a proper HasProperty() check in the memory and table setup. · 7bffaaac
      ahaas authored 
      The WebAssembly spec requires a HasProperty() check for the maximum
property of the descriptor object which is used to set up a
WebAssembly.Memory object or a WebAssembly.Table object.

The original implementation only approximated the HasProperty() check.
It used Get() to get the value of the maximum property of the descriptor
object and compared the resulting value to {undefined}. However, this
approximation is incorrect if the property exists but its value is
{undefined}.

      Enable component builds for fuzzers · 22606f0c
      jgruber authored 
      V8 is collecting a growing amount of fuzzers, all of which take substantial
space on the bots and in chromium build archives. This CL improves that
situation by allowing component (shared library) builds for almost all fuzzers.

The parser fuzzer is handled as an exception since it would require exporting a
large number of additional functions.

A component build results in about a 50-100x improvement in file size for each
fuzzer (~50M-100M to around 1.1M).
