[wasm] Store trap handler index as int · 444ee7bd

Clemens Hammacher authored Apr 30, 2019

The index is an {int} initially. We then store it as {intptr_t}, and
the accessor returns it as {size_t}.
This CL consolidates everything to {int}, fixes naming of
{HasTrapHandlerIndex} and defines the simple accessors inline.

PPC/s390: Reland "[ptr-compr] New RelocInfo for compressed pointers." · 2054c4a1

Milad Farazmand authored May 01, 2019

Original Commit Message:

    Original Commit Message:

        Failure addressed by not exposing the new test to the jitless environment.
        (jgruber@ on TBR).

        New enum RelocInfo::COMPRESSED_EMBEDDED_OBJECT created to support
        compressed pointers in generated code. Enum name EMBEDDED_OBJECT
        changed to FULL_EMBEDDED_OBJECT.

        RelocInfo::[set_]target_object() abstract away the difference between
        FULL_EMBEDDED_OBJECT and COMPRESSED_EMBEDDED_OBJECT.

        Compressed embedded objects can only be created at this time on
        x64 with pointer compression turned on. Arm64 constant pools don't
        support compressed objects at this time.

PPC/s390: [cleanup] Use Vector::begin instead of Vector::start · 3335d813

Milad Farazmand authored Apr 30, 2019

Port 08756826

Original Commit Message:

    Port 4b0f9c85

    Original Commit Message:

        Our {Vector} template provides both {start} and {begin} methods. They
        return exactly the same value. Since the {begin} method is needed for
        iteration, and is also what standard containers provide, this CL
        switches all uses of the {start} method to use {begin} instead.

        Patchset 1 was auto-generated by using this clang AST matcher:
            callExpr(
                callee(
                  cxxMethodDecl(
                    hasName("start"),
                    ofClass(hasName("v8::internal::Vector")))
                ),
                argumentCountIs(0))

        Patchset 2 was created by running clang-format. Patchset 3 then
        removes the now unused {Vector::start} method.

[wasm] Store and pass compilation units by value · 7dbdb055

Clemens Hammacher authored Apr 30, 2019

Wasm compilation units got smaller and smaller with recent refactorings
(https://crrev.com/c/1587386, https://crrev.com/c/1587387,
https://crrev.com/c/1587388, plus previous CLs).
They now only store a function index and the requested compilation
tier. Hence there is no reason any more to heap-allocate them.
This CL changes the compilation unit queues and interfaces to store and
pass compilation units by value. Methods that could return an empty
{unique_ptr} before are now returning a {base::Optional}.

    New enum RelocInfo::COMPRESSED_EMBEDDED_OBJECT created to support
    compressed pointers in generated code. Enum name EMBEDDED_OBJECT
    changed to FULL_EMBEDDED_OBJECT.

    RelocInfo::[set_]target_object() abstract away the difference between
    FULL_EMBEDDED_OBJECT and COMPRESSED_EMBEDDED_OBJECT.

    Compressed embedded objects can only be created at this time on
    x64 with pointer compression turned on. Arm64 constant pools don't
    support compressed objects at this time.

[arm] Fix relative code target relocation · 397f53ed

Jakob Gruber authored Apr 24, 2019

Relative code targets are emitted as pc-relative jumps. The
relocation delta must be subtracted (not added) from the branch
offset.

Before GC:

        |-------- branch offset --->|
 [host code object]                 [target code object]

After GC:

 |- delta ->|      |- new offset -->|
            [host code object]      [target code object]

This CL refactors WasmTableObject::Grow to make it usable for the
table.grow instruction of WebAssembly.

The refactored version of WasmTableObject::Grow does additionally:
* Check if growing is possible
* Grow the FixedArray backing store of the table and initialize the new
  fields.
* Calculate the return value of WasmTableObject::Grow.
