      [wasm] Remove WasmCompilationData · 1a5df8eb
      Ben L. Titzer authored 
      The WasmCompilationData was a struct that served as an input/output
mechanism for communicating with the code generator. In particular,
it contained a flag for enabling runtime exception for WASM in the code
generator and it also gathered the protected instruction info from
the code generator to be communicated to the WasmCodeManager.

This CL inlines the exception support flag into OptimizedCompilationInfo
and the protected instruction information into the code generator,
along the lines of other flags and data structures created by the
code generator.

      Move CompilationDependencies into compiler. · cf87e94c
      Georg Neis authored 
      - Move the CompilationDependencies member of OptimizedCompilationInfo
  to Turbofan's PipelineData (and thus into the compiler namespace).
- Move compilation-dependencies.{cc,h} to the compiler directory.

      Replace array index masking with the poisoning approach. · f53dfd93
      Jaroslav Sevcik authored 
      The idea is to mark all the branches and loads participating in array
bounds checks, and let them contribute-to/use the poisoning register.
In the code, the marks for array indexing operations now contain
"Critical" in their name. By default (--untrusted-code-mitigations),
we only instrument the "critical" operations with poisoning.

With that in place, we also remove the array masking approach based
on arithmetic.

Since we do not propagate the poison through function calls,
we introduce a node for poisoning an index that is passed through
function call - the typical example is the bounds-checked index
that is passed to the CharCodeAt builtin.

Most of the code in this CL is threads through the three levels of
protection (safe, critical, unsafe) for loads, branches and flags.

      [turbofan] unify interpreter and JIT speculation poisoning · 1ef6c437
      Tobias Tebbi authored 
      This CL changes the poisoning in the interpreter to use the
infrastructure used in the JIT.

This does not change the original flag semantics:

--branch-load-poisoning enables JIT mitigations as before.

--untrusted-code-mitigation enables the interpreter mitigations
  (now realized using the compiler back-end), but does not enable
  the back-end based mitigations for the Javascript JIT. So in effect
  --untrusted-code-mitigation makes the CSA pipeline for bytecode handlers
  use the same mechanics (including changed register allocation) that
  --branch-load-poisoning enables for the JIT.

      [turbofan] Masking/poisoning in codegen (optimized code, x64) · 8f489e73
      Mike Stanton authored 
      This introduces masking of loads with speculation bit during code generation.
At the moment, this is done only for x64 optimized code, under the
--branch-load-poisoning flag.

Overview of changes:
- new register configuration configuration with one register reserved for
  the speculation poison/mask (kSpeculationPoisonRegister).
- in codegen, we introduce an update to the poison register at the starts
  of all successors of branches (and deopts) that are marked as safety
  branches (deopts).
- in memory optimizer, we lower all field and element loads to PoisonedLoads.
- poisoned loads are then masked in codegen with the poison register.
  * only integer loads are masked at the moment.

      [Ignition] [TurboFan] Generate speculation poison in code generator. · a021b6c4
      Ross McIlroy authored 
      Moves generation of speculation poison to be based on the PC target vs the
actual PC being executed. The speculation poison is generated in the prologue
of the generated code if CompilationInfo::kGenerateSpeculationPoison is set.
The result is stored in a known register, which can then be read using the
SpeculationPoison machine node.

Currently we need to ensure the SpeculationPoison node is scheduled right after
the code prologue so that the poison register doesn't get clobbered. This is
currently not verified, however it's only use is in RawMachineAssembler where
it is manually scheduled early.

The Ignition bytecode handlers are updated to use this speculation poison
rather than one generated by comparing the target bytecode.

      [wasm] JIT using WasmCodeManager · d4c8393c
      Mircea Trofin authored 
      This is the first step towards wasm code sharing. This CL moves wasm
code generation outside the JavaScript GC heap using the previously -
introduced WasmCodeManager (all this, behind the --wasm-jit-to-native
flag).

See design document: go/wasm-on-native-heap-stage-1

This CL doesn't change other wasm architectural invariants. We still
have per-Isolate wasm code generation, and per-wasm module instance
code specialization.
