Hi,
I'm trying to modify the NPTL's /pthread_cond_wait.S/ file for i486.
This file contains two sections '.eh_frame' and '.gcc_except_table'.
After some research, I've found that the former obeys more or less the
DWARF2 format (with GNU augmentation) and the is like a Language-
Specific Data Area.
My question is, where can I find the description of the GNU augmentation
for DWARF2 and for the LSDA? I've found a document explaining how LSDA
is used in C++ exception handling, but the format has some differences
(the header section differs, the .uleb128 0 field is not expected, ...).
TIA, hoping that such documentation does exist...
Seb.
