[Bug java/31325] gcj support for ARM EABI

Sat Mar 24 19:58:00 GMT 2007

------- Comment #11 from s_j_newbury at yahoo dot co dot uk  2007-03-24 19:58 -------
I have everything built except for libjava/exception.cc which fails as seen
below.

This I believe is due to the lack of an implementation of _Unwind_Backtrace in
the ARM EABI.  What needs to be done to address this?  Can anybody give me any
pointers?  

In http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29206 Daniel Jackobowitz says
"As for ARM, I'm not sure what to do to fix the issue.  ARM old ABI is stuck
with SJLJ.  And the EABI can't implement _Unwind_Backtrace either.  I have been
speaking with someone at ARM about the ABI implications of this, on and off,
but I don't have a lot of hope for it working out without a GNU extension."
