            Bug ID: 153463
           Summary: [mips] don't save to a callee saved register too early
    Classification: Unclassified
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Other
                OS: Linux
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: guijemont at igalia.com

If we save $gp to $s4 in pichdr, then in some cases, we were overwriting $s4 before LLInt's pushCalleeSaves() is called (as pichdr is at the very beginning of a function).
