function trace back and address to line number conversion
Hi,
I am new to AIX and I am developing a small tool for our product which helps debug memory leaks etc.

Q1)Is there a way in which i can get a function trace back as to the call (lets say malloc() )has been made in which file--> in which function.

I tried using the

#pragma options ( i might be making a mistake in the sub options for tbtable would need guidance here too)
and

-qtbtable=full

which says that a full stack trace would be appended as a text file at the end of the object file that we create if we create the obj file using the -g option.

But I dont seem to see any stack trace at the end of the obj file.
Can someone tell me what possibly could be my mistake? or suggest a better way of getting a stack trace


now using __builtin_return_address() i can get the code address from where the fucntion call ( malloc() ) has been made.

Q2)Is there any function which will help me find the line number of the function call ( malloc() ).

On HP UX we have addr2line() function which does this thing... on AIX i dont have an idea which function does it.

Thank you very much in advance.
Regards

ovs-parse-leaks

ovs-parse-leaks(8)						Open vSwitch Manual						ovs-parse-leaks(8)

NAME

       ovs-parse-leaks - parses OVS leak checker log files

SYNOPSIS

       ovs-parse-leaks [binary] < log

DESCRIPTION

       Many  Open  vSwitch  daemons  accept a --check-leaks option that writes information about memory allocation and deallocation to a log file.
       ovs-parse-leaks parses log files produced by this option and prints a summary of the results.  The most interesting part of the output is a
       list of memory blocks that were allocated but not freed, which Open vSwitch developers can use to find and fix memory leaks.

       The  log  file must be supplied on standard input.  The binary that produced the output should be supplied as the sole non-option argument.
       For best results, the binary should have debug symbols.

OPTIONS

       --help Prints a usage message and exits.

BUGS

       The output can be hard to interpret, especially for a daemon that does not exit in normal operation.  Using  ovs-appctl(8)  to  invoke  the
       exit command that some Open vSwitch daemons support sometimes helps with this.

       ovs-parse-leaks	usually  incorrectly  reports one or more ``bad frees of not-allocated address'' errors at the beginning of output.  These
       reflect frees of data that were allocated before the leak checker was turned on during program initialization.
