Error reading LLVM-gcc debug info

[Kevin Tew]

zero gives gives an error message it can't open the following file.
/home/tewk/srcs/llvm-gcc/install/bin/../lib/gcc/i686-pc-linux-gnu/
4.0.1/include//home/tewk/srcs/manta/StandAlone/manta.cc:195s

Which of course should be two paths.
/home/tewk/srcs/llvm-gcc/install/bin/../lib/gcc/i686-pc-linux-gnu/
4.0.1/include/
/home/tewk/srcs/manta/StandAlone/manta.cc:195

The executable was created using llvm-gcc, but gdb is able to read the
debug info just fine.

Ideas?

Can you please tell me what distro and ZeroBUGS build are you experiencing this problem with?

Thank you,

Kevin,

I reproduced the problem with llvm-gcc4.0.2 on a Ubuntu desktop.

Interestingly enough, this behavior is a combination of two bugs: first one in the llvm-gcc compiler  (the DW_AT_comp_dir attribute of compilation units in the .debug section seems to be incorrect, as verified with the dwarfdump and readelf utilities) and the second: an "optimization" in computing the source file name that I pushed out with the latest build of Zero.

Good news is I do have a workaround and I will start pushing new builds out (hopefully this coming weekend).

Thank you kindly for bringing up this issue.

Best regards,
   Cristian
