Hi,
Could a gate keeper please review the attached patch to fix bug #944.
This fix solves a problem in debugging the open64 generated binaries. Currently
if we compile a file which is in different directory than the working
directory, it cannot be debugged.
$pwd
/tmp
$opencc -g test_dir/t1.c
$gdb a.out
(gdb) b main
(gdb) run
Breakpoint 1, main () at t1.c:6
6 t1.c: No such file or directory.
in t1.c
We don't generate the path information for ".file" directives in the generated
assembly and due to this directory table entries are not not created correctly.
This patch generates the ".file" directives similar to gcc and fixes the
problem.
Regards,
Shivaram
