Reason for revert: Failures on greedy RegAlloc, Fuzzer Original issue's description: > Remove register index/code indirection > > Previous to this patch, both the lithium and TurboFan register > allocators tracked allocated registers by "indices", rather than > the register codes used elsewhere in the runtime. This patch > ensures that codes are used everywhere, and in the process cleans > up a bunch of redundant code and adds more structure to how the > set of allocatable registers is defined. > > Some highlights of changes: > > * TurboFan's RegisterConfiguration class moved to V8's top level > so that it can be shared with Crankshaft. > * Various "ToAllocationIndex" and related methods removed. > * Code that can be easily shared between Register classes on > different platforms is now shared. > * The list of allocatable registers on each platform is declared > as a list rather than implicitly via the register index <-> > code mapping. > > Committed: https://crrev.com/80bc6f6e11f79524e3f1ad05579583adfd5f18b2 > Cr-Commit-Position: refs/heads/master@{#30913} TBR=akos.palfi@imgtec.com,bmeurer@chromium.org,jarin@chromium.org,paul.lind@imgtec.com,titzer@chromium.org NOPRESUBMIT=true NOTREECHECKS=true NOTRY=true Review URL: https://codereview.chromium.org/1365073002 Cr-Commit-Position: refs/heads/master@{#30914} |
