pahole doesn't understand the new DWARF 4 .debug_types section.
I'm using the F15 GCC, but really any recent-enough GCC will do.
I compile this:
struct s
{
int x;
int y : 5;
int z;
};
struct s i;
int main()
{
}
Like so:
gcc -gdwarf-4 -g -o d d.c
Running pahole gives an error:
$ pahole --class_name=s ./d
tag__recode_dwarf_type: couldn't find 0x1d type for 0x51 (variable)!
It would be nice to have support for this feature in dwarves, as
.debug_types can greatly reduce the size of the debuginfo in the final
executable.
