Reason for revert: Breaks nosnap, needs investigation Original issue's description: > [builtins] Unify the various versions of [[Call]] with a Call builtin. > > The new Call and CallFunction builtins supersede the current > CallFunctionStub (and CallIC magic) and will be the single bottleneck > for all calling, including the currently special Function.prototype.call > and Function.prototype.apply builtins, which had handwritten (and > not fully compliant) versions of CallFunctionStub, and also the > CallIC(s), which where also slightly different. > > This also reduces the overhead for API function calls, which is still > unnecessary high, but let's do that step-by-step. > > This also fixes a bunch of cases where the implicit ToObject for > sloppy receivers was done in the wrong context (in the caller > context instead of the callee context), which basically meant > that we allowed cross context access to %ObjectPrototype%. > > MIPS and MIPS64 ports contributed by akos.palfi@imgtec.com. > > R=mstarzinger@chromium.org, jarin@chromium.org, mvstanton@chromium.org > CQ_INCLUDE_TRYBOTS=tryserver.v8:v8_linux_layout_dbg > BUG=v8:4413 > LOG=n > > Committed: https://crrev.com/ef268a83be4dead004047c25b702319ea4be7277 > Cr-Commit-Position: refs/heads/master@{#30627} TBR=rmcilroy@chromium.org,jarin@chromium.org,mstarzinger@chromium.org,mvstanton@chromium.org NOPRESUBMIT=true NOTREECHECKS=true NOTRY=true BUG=v8:4413 Review URL: https://codereview.chromium.org/1328963004 Cr-Commit-Position: refs/heads/master@{#30628} |
