Help with GCC (port-vax/44155)
GCC has some code for DWARF2 stack unwinding on VAX but it's neither
correct, nor complete, so C++ exceptions currently don't work on VAX
I did some initial investigation, but my gcc fu is not enough to fix
it completely. Details in port-vax/44155, but the summary is:
. fix FRAME_POINTER_CFA_OFFSET
. provide "eh_return" instruction pattern
(the asm code to be emited is in the PR)
. what are compatibility implications of introducing
DWARF2 column for saved PSW?
If we can fix exceptions, than I guess someone can setup ATF runs
with Anita (http://www.gson.org/netbsd/anita/) but using SIMH instead
of QEMU (as we already do for i386, amd64 and sparc).
