            Bug ID: 243888
           Summary: Air support in Armv7 will not use advanced SIMD FP
                    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: jgriego at igalia.com

Although there are advanced SIMD extensions to ARMv7 that add an extra 16 floating point registers--these can't be used as f32 operands and so we can't let Air use them without adjusting Air to have some idea about multiple classes of register within the FP bank--on currently supported architectures, any FP register is as good as any other for any operation.

Only relevant after https://bugs.webkit.org/show_bug.cgi?id=241009 is resolved.
