#1 Debug Information

[Christoph Schwarz]

Reading debug information might need revision for all environments. Make sure that debug information is read properly (to check if debug information is read, use: valgrind --trace-symtab=yes \<program>).

This task includes:

• document supported debug formats
• coregrind/m_debuginfo/readdwarf.c : find reason for having Windows-specific 'if (blklen == 0) return;' in ML_(read_debuginfo_dwarf3) or remove it
• coregrind/m_debuginfo/readstabs.c : find reason for having Windows-specific code; check if struct nlist is valid for 64 bit
• coregrind/m_debuginfo/storage.c : find reason for having Windows-specific 'if ( loc->size <= 0 ) return;' in addLoc() or remove it
