Hi all,
I just started using the MIPS port of V8. So far I'm using the 'shell'
program to run JS code. Everything works fine unless the '--debug-
code' switch is enabled. With the switch, an "unexpected declaration
in current context" error error pops out (the full message text is
below).
A brief evaluation revealed that it only happens when a nested JS
function accesses a variable that is defined in the enclosing function
body. For instance, when the nested function SetupArray.getFunction()
accesses the SetupArray.specialFunctions variable, in src/array.js.
I do realize that the MIPS port is out of the official scope, but the
full-codegen part (which pops out the error) is very similar in all V8
ports. So could someone point out what the reason could be? What
should be checked fist?
Thanks.
