about class LOC_COMPUTED_ARG

[ankit thukral]

hi all,    
    this is about the address class of the symbols
(arguments or local symbols) which is LOC_COMPUTED.for
this class , the value of the symbol is calculated by
calling some function called locexpr_read_variable()
which is stored in as a function pointer as against
the class LOC_BASEREG in which the location of the
symbols is calculated using the "base register +
offset" approach. 
while debugging a process,i noticed that the argument
of some function had the address class LOC_BASEREG_ARG
while the same had LOC_COMPUTED_ARG in an older
version and newer version of GDB respectively.can
anyone tell me the reason for this shift i noticed? is
the class LOC_BASEREG_ARG becoming deprecated or is it
sort of buggy?
  


thanks in advance,
ankit.
