      This commit is the first step towards emitting unwinding information in · 7d073b03
      ssanfilippo authored 
      the .eh_frame format as part of the jitdump generated when
FLAG_perf_prof is enabled. The final goal is allowing precise unwinding
of callchains that include JITted code when profiling V8 using perf.

Unwinding information is stored in the body of code objects after the
code itself, prefixed with its length and aligned to a 8-byte boundary.
A boolean flag in the header signals its presence, resulting in zero
memory overhead when the generation of unwinding info is disabled or
no such information was attached to the code object.

A new jitdump record type (with id 4) is introduced for specifying
optional unwinding information for code load records. The EhFrameHdr
struct is also introduced, together with a constructor to initialise it
from the associated code object.

At this stage no unwinding information is written to the jitdump, but
the infrastructure for doing so is ready in place.

      [Reland] Refactor CpuProfiler. · 04f710ac
      lpy authored 
      Currently CpuProfiler is a subclass of CodeEventListener, it listens code events
from Logger, constructs and stores CodeEventsContainer. This patch is part of
the effort to split the logic of CodeEventListener as ProfilerListener out of
the profiling functionality logic in CpuProfiler. A ProfilerListener will listen
to code events, construct code event to CodeEventsContainer and pass it to code
event handler.

The reason we refactor CpuProfiler is that eventually we want to move
CpuProfiler as part of sampler library and code event listener should stay
inside V8.

Main changes:
1. Refactored CpuProfiler into two parts, the CpuProfiler with profling
functionality and the ProfilerListener listening to code events from Logger.
2. Created CodeEventObserver and made CpuProfiler inherit from it.
ProfilerListener will have a list of observers and call CodeEventHandler once a
code event is created.
3. Moved code entry list from CodeEntry to ProfilerListener.

Minor changes:
1. Moved static code entry as part of CodeEntry.
2. Added ProfilerListener to Logger.

      [builtins] Introduce proper Float64Tan operator. · c87168bc
      bmeurer authored 
      Import base::ieee754::tan() from fdlibm and introduce Float64Tan TurboFan
operator based on that, similar to what we do for Float64Cos and Float64Sin.
Rewrite Math.tan() as TurboFan builtin and use those operators to also
inline Math.tan() into optimized TurboFan functions.

Drive-by-fix: Kill the %_ConstructDouble intrinsics, and provide only
the %ConstructDouble runtime entry for writing tests.

      [turbofan] Retiring Greedy Allocator · 8e1ccba3
      mtrofin authored 
      We were able to achieve our goals for register allocation independent of
the allocation algorithm. Performance data so far is inconclusive re. the
value of the Greedy algorithm, compared to the particular Linear Scan
implementation we're currently using, and the performance measurement
techniques we currently use are too imprecise to help with this matter.

Retiring the algorithm to lower maintenance and evolution cost (e.g. lower
cost of adding aliasing support). Once we improve benchmarking stability,
and establish a suite sensitive enough for codegen improvement studies,
we may revive the algorithm, should the need arise.

      [builtins] Introduce proper base::ieee754::log. · d0c7775d
      bmeurer authored 
      This switches Math.log to use an fdlibm based version of log, imported
as base::ieee754::log, and use that consistently everywhere, i.e. change
the Float64Log TurboFan operators on Intel to use the C++ implementation
as well (same for Crankshaft).
