Hi, Andrew
I can understand the requirement of linking with the newer version GCC
to provide the dbase symbol. I'm just trying to understand how EH will
work when some objects have EH with absolute references in the data
section and some have relative references in the text section. I guess
the in
Hi David,
On AIX, mixing objects from different GCC versions should work as long
as the newest GCC is used for linking. I tested a library with some
objects compiled by GCC-4.4 and some objects compiled by a patched
GCC-5.0. Exceptions passed through the mixed objects without issue.
Did you have

Hi David,
As discussed, I have updated the to use SYMBOL-$ syntax for
PC-relative addressing and to use a new symbol, __gcc_unwind_dbase,
rather than overloading __dso_handle.

Move exception tables to read-only memory on AIX.

That comment is very old. I'm not sure what the ori

Hi,
The following patch moves dwarf unwind information from the data
section to the read-only/text section on AIX. This means the memory
for the unwind information can be shared across multiple processes.
The frame tables are still registered through collect2 scanning for
"_GLOBAL_F" symbol name
