__ pop(eax); ... __ push(eax); to enable push/pop eliminations. __ push(eax) must happen before RecordWrite because RecordWrite may destroy eax value. To be safe, also moved __ push(r0) on ARM to above RecordWrite. This only affects the case where a context variable is used in a inner scope. Create a tests for it. It fails if __ push(eax) is after RecordWrite. git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@111 ce2b1a6d-e550-0410-aec6-3dcde31c8c00
