Summary: Remove some unreachable code (-Wunreachable-code)
Product: WebKit
Version: 528+ (Nightly build)
Platform: Unspecified
OS/Version: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: WebCore Misc.
AssignedTo: webkit-unassigned at lists.webkit.org
ReportedBy: joepeck at webkit.org

Remove some straightforward cases of unreachable code. I believe these are all break statements that have a return, goto, or another break immediately preceding them.
It may not be possible to enable -Wunreachable-code by default. There are many places where we have code after CRASH() / NO_RETURN functions, return values after switches that return for all possible values, code that compiles differently on 32/64bit that statically eliminate branches (if sizeof(...)), debug only code enabled/disabled by static booleans that are false, and more. I did file some bugs on real cases of unreachable code that this caught; nothing significant.
