I don't know of any docs. Docs would be nice.
Here is the comment from gcc/dwarf2out.c:
/* Augmentation:
z Indicates that a uleb128 is present to size the
augmentation section.
L Indicates the encoding (and thus presence) of
an LSDA pointer in the FDE augmentation.
R Indicates a non-default pointer encoding for
FDE code pointers.
P Indicates the presence of an encoding + language
personality routine in the CIE augmentation. */
gcc before 3.0 used a different scheme, which you can probably ignore.
In that scheme the augmentations were exactly the three bytes "eh\0".
Thanks.
I've been asked to write a description for the PowerPC ABI.
I'll reverse-engineer the table unless I can find something
more descriptive than the comments in gcc or gdb.
