d3a4d15f5e [assembler] Unify RelocInfo::NONE32 and NONE64
This reloc mode is never encoded, so there is no reason to
differentiate between 32 and 64 bit.
Both are now replaced by RelocInfo::NONE.

7d38ee3011 [iwyu] Do not include frames.h in macro assemblers.
Since frames.h no longer defines basic register types like RegList, it
is no longer necessary to include it in the macro assemblers.

Next step: split out frame-constants.h from frames.h so that it will be
possible to get frame constants without include the stackwalking logic,
which needs objects.h.

2f79e03560 [builtins] Remove Builtins::Name() accessors
Instead of auto-generating the Name() convenience accessor, use a macro to
avoid wasting code space.

  BUILTIN_CODE(isolate, Name)

expands to

  isolate->builtins()->builtin_handle(Builtins::kName);

This reduces the size of libv8.so by 134,752 bytes on a x64 release build.

Later then, in Assembler::GetCode, allocate the heap numbers and patch
the code by replacing the dummies with the actual objects. The
RelocInfos for the embedded objects are already recorded correctly when
emitting the dummies.

3f47c63ded [liveedit] reimplement frame restarting.
Previously, when restarting a frame, we would rewrite all frames
between the debugger activation and the frame to restart to squash
them, and replace the return address with that of a builtin to
leave that rewritten frame, and restart the function by calling it.

We now simply remember the frame to drop to, and upon returning
from the debugger, we check whether to drop the frame, load the
new FP, and restart the function.

479de28c3a Revert of Adding ia32 simd assembler changes. (patchset #2 id:20001 of https://codereview.chromium.org/1991713002/ )
Reason for revert:
Crashes on win32 debug:
https://build.chromium.org/p/client.v8/builders/V8%20Win32%20-%20debug/builds/2305/steps/Check/logs/stdio

Also, would be nice if the test output could be a bit shorter and only print what's necessary to trace a failure. Or split things into more smaller tests. Like that, these logs must be processed, json-encoded/decoded and sent around through the infrastructure.

Some chars in the output make the json encoder unhappy, therefore the infrastructure can't nicely display the failures.

22523f25b1 Extends testb and cmpb/cmpw instruction support in the ia32 assembler.
This is in preparation for a CL that does the equivalent of http://crrev.com/1780193003 for ia32.

1b23079936 [wasm] Int64Lowering of Int64Add on ia32 and arm.
Int64Add is lowered to a new turbofan operator, Int32AddPair. The new
operator takes 4 inputs an generates 2 outputs. The inputs are the low
word of the left input, high word of the left input, the low word of the
right input, and high word of the right input. The ouputs are the low
and high word of the result of the addition.

I implemented I64ShrU and I64ShrS the same as I64Shl in https://codereview.chromium.org/1756863002

ddc626e1cf [wasm] Int64Lowering of I64Shl on ia32.
I64Shl is lowered to a new turbofan operator, WasmWord64Shl. The new
operator takes 3 inputs, the low-word input, the high-word input, and
the shift, and produces 2 output, the low-word output and the high-word
output.

At the moment I implemented the lowering only for ia32, but I think the
CL is already big enough. I will add the other platforms in separate
CLs.

8dad78cdbd [turbofan] Add backend support for float32 operations.
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.

99f8d57f3c [turbofan] Introduce optional Float64Min and Float64Max machine operators.
Basically recognize certain x < y ? x : y constructs and turn that into
Float64Min/Float64Max operations, if the target machine supports that.
On x86 we lower to (v)minsd/(v)maxsd.

4436c2642a [turbofan] Support for %_DoubleHi, %_DoubleLo and %_ConstructDouble.
This adds support for the double bits intrinsics to TurboFan, and is
a first step towards fast Math functions inlined into TurboFan code
or even compiled by themselves with TurboFan.
