Description Andrew Cagney 2007-11-07 21:01:07 UTC

(fhpd) plocation argv
[0.0]

Address 0xffffffffbfc9cd04 - 4 byte(s)

Comment 1 Teresa Thomas 2007-11-12 20:34:31 UTC

Bug reproducible only for arguments to main so far (32 bit). Does not sign
extend plocation on arguments to non-main methods, and declared variables.

(fhpd) plocation argc
[0.0]

Address 0xffffffffbfdf5560 - 4 byte(s)
(fhpd) plocation a   // where a is argument to a non main function.
[0.0]

Address 0xbfceb420 - 4 byte(s)
(fhpd) plocation static_int_address 
[0.0]

Address 0x804988c - 4 byte(s)
