We can use xorps/xorpd on Intel CPUs to flip the sign bit. Ideally we'd
use a RIP-relative 128-bit constant in the code object, as OCaml/GCC

adamk [Tue, 7 Apr 2015 00:11:48 +0000 (17:11 -0700)]
Reimplement Maps and Sets in JS

Previously, the only optimized code path for Maps and Sets was for String keys.
This was achieved through an implementation of various complex operations
in Hydrogen. This approach was neither scalable nor forward-compatible.

This patch adds the necessary intrinsics to implement Maps and Sets almost entirely
in JS. The added intrinsics are:

  %_FixedArrayGet
  %_FixedArraySet
  %_TheHole
  %_JSCollectionGetTable
  %_StringGetRawHashField

With these additions, as well as a few changes to what's exposed as runtime functions,
most of the C++ code backing Maps and Sets is gone (including both runtime code in
objects.cc and Crankshaft in hydrogen.cc).

Original commit message:
This adds the basics necessary to support float32 operations in TurboFan.
The actual functionality required to detect safe float32 operations will

In detail, this patchset contains the following features:
- Add support for float32 operations to arm, arm64, ia32 and x64
  backends.
- Add float32 machine operators.
- Add support for float32 constants to simplified lowering.
- Handle float32 representation for phis in simplified lowering.

In addition, contains the following (related) cleanups:
- Fix/unify naming of backend instructions.
- Use AVX comparisons when available.
- Extend ArchOpcodeField to 9 bits (required for arm64).
- Refactor some code duplication in instruction selectors.

Fix libdl dependency on Android and remove librt hack.

The libdl library is already included on target builds of Android and needs
to be added to the build command line with a particular order to avoid
undefined references in other libraries. Fix this by only explicitly including
it in host builds and relying on the implicit inclusion on target builds.

Also remove the librt hack which is not longer necessary due to the AOSP build
bot having been removed.

MIPS64: [turbofan] Add backend support for float32 operations.

Port 8dad78cdbd21c2cd02d6e0645313bd4b9983c78e

Original commit message:
This adds the basics necessary to support float32 operations in TurboFan.
The actual functionality required to detect safe float32 operations will
be added based on this later. Therefore this does not affect production
code except for some cleanup/refactoring.

In detail, this patchset contains the following features:
- Add support for float32 operations to arm, arm64, ia32 and x64
  backends.
- Add float32 machine operators.
- Add support for float32 constants to simplified lowering.
- Handle float32 representation for phis in simplified lowering.

In addition, contains the following (related) cleanups:
- Fix/unify naming of backend instructions.
- Use AVX comparisons when available.
- Extend ArchOpcodeField to 9 bits (required for arm64).
- Refactor some code duplication in instruction selectors.

9 years agoARM simulator needs a StackCheck in GetPropertyWithDefinedGetter.
mvstanton [Tue, 31 Mar 2015 10:37:34 +0000 (03:37 -0700)]
ARM simulator needs a StackCheck in GetPropertyWithDefinedGetter.

Because simulators have a seperate JavaScript and C++ stack, and
because they try to avoid calling the runtime StackCheck function
on entry to every function, it can happen in recursive calls that
the C++ stack overflows while the JavaScript stack is okay. The
runtime StackCheck function would catch this, but as an optimization,
generated code only looks at the JavaScript stack pointer to
determine if it should make that runtime call.

can end up repeatedly making no progress (e.g., if it can't finalize a sweep)
