Description M R Swami Reddy 2009-03-23 12:39:56 UTC 
With -g -O2 option, crx-elf-gcc generates wrong line numbers and function names.
==
/tmp/ccrrZsJf.o: In function `090312 (experimental)':
/home10/swami/test.c:5: undefined reference to `_f1'
collect2: ld returned 1 exit status
===

Expected output could be:
===
/tmp/ccEJcFRs.o: In function `main':
/home10/swami/test.c:6: undefined reference to `_f1'
collect2: ld returned 1 exit status
----


testcase: "test.c"
====

int f = 1;
extern int f1 ();

main () {
   f1();
}

This is a binutils issue.  The error is reported with the location of the
calling function, not the call.
