      [wasm] Move wasm-macro-gen.h to test/common/wasm · fc6d4a1f
      Clemens Hammacher authored 
      This header file is only used from tests.
Also, move the LoadStoreOpcodeOf method (only used in tests) from
wasm-opcodes.h to wasm-macro-gen.h.

      [wasm] Reuse LEB encoding logic in module builder · 4531c865
      Clemens Hammacher authored 
      Instead of using the WASM_I32V_* macros (and other) from
wasm-macro-gen.h, use the appropriate methods to encode LEB integers.
This also saves some spaces for the wasm bytecode generated from asm.js.

Specifically, this CL
1) renames EmitVarInt to EmitI32V and EmitVarUint to EmitU32V (on
   WasmFunctionBuilder).
2) introduces more methods on the WasmFunctionBuilder to emit i64v,
   u64v, f32, and f64 values.
3) uses the ZoneBuffer instead of a plain ZoneVector<char> in the
   WasmFunctionBuilder to build the body of the function.
4) introduces more helper functions on the ZoneBuffer to encode i64v,
   u64v, f32 and f64 values.

      [asm.js] Refactor parser identifier memory management. · c2abd807
      Michael Starzinger authored 
      This unifies the memory management of identifier strings passed between
the scanner, parser and module builder. The following scheme is used:
 - The scanner does not create copies of identifier strings itself, it
   exposes a reference to the current identifier. This reference becomes
   invalid as soon as the scanner advanced.
 - The parser preserves a single copy of each identifier that is stored
   in any data structure. That copy is allocated in the zone, lifetime
   is coupled to that of the zone.
 - The module builder can use all such identifiers by reference, as long
   as its lifetime is also coupled to the same zone.

Note that the module builder still creates redundant copies for some
identifiers (in order to maintain backwards compatibility with the old
AST-based parser). This can be fixed once the "old validator" has been
removed.

      [asm.js] Test and fix "|0" annotation of calls. · f0946038
      Michael Starzinger authored 
      This fixes the validation of "|0" annotations of call sites that are
used to indicate a "signed" return type of functions. We use lookahead
during call validation and request deferred validation as part of the
actual OR-expression. Special care has to be taken to get precedence
levels of all involved operators right.
