            Bug ID: 249648
           Summary: Air should use more ARMv7 registers
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: angelos at igalia.com

Currently, MacroAssemblerARMv7 reserves 2 scratch registers for use in certain cases of code generation. If Air can be taught to avoid generating long offsets, we can reclaim one register for use in the register allocator.
