            Bug ID: 218703
           Summary: [JSC][MIPS] Stress tests with '-e' parameters in
                    requireOptions fail with bytecode cache enabled
           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: xan.lopez at gmail.com

Some stress tests have a line like:

//@ requireOptions("-e", "let iterations=1e5") if ["mips"].include?($architecture)

to reduce the number of iterations on MIPS (since its bots are slower).

This causes bugs with the bytecode cache enabled, seemingly because issues with (lack of) double quoting:

stress/generator-cell-with-type.js.bytecode-cache: Could not open file: iterations=1e5
stress/generator-cell-with-type.js.bytecode-cache: Exception: ReferenceError: Can't find variable: let
stress/generator-cell-with-type.js.bytecode-cache: global code@[Command Line]:1:4

This is a blocker to enable bytecode cache support on MIPS.
