commit 9eed92a0b47ebc25932ced9b5db86b66b59f7857
Author: Thomas Schwinge <tschwi...@baylibre.com>

GCN, nvptx: Define '_Unwind_DeleteException'
This resolves GCN:
ld: error: undefined symbol: _Unwind_DeleteException
>>> referenced by eh_catch.cc:109
([...]/source-gcc/libstdc++-v3/libsupc++/eh_catch.cc:109)
>>> eh_catch.o:(__cxa_end_catch) in archive
[...]/build-gcc/amdgcn-amdhsa/libstdc++-v3/src/.libs/libstdc++.a
[...]
collect2: error: ld returned 1 exit status
..., and nvptx:
unresolved symbol _Unwind_DeleteException
collect2: error: ld returned 1 exit status
For both GCN, nvptx, this each progresses ~100 'check-gcc-c++',
and ~500 'check-target-libstdc++-v3' test cases:
[-FAIL:-]{+PASS:+} [...] (test for excess errors)
..., with (if applicable, for most of them):
[-UNRESOLVED:-]{+PASS:+} [...] [-compilation failed to produce
executable-]{+execution test+}
..., or just a few 'FAIL: [...] execution test' where these test cases now
FAIL for unrelated reasons, or, if applicable, FAIL due to run-time
'GCC/nvptx: sorry, unimplemented: dynamic stack allocation not supported'.
libgcc/
* config/gcn/unwind-gcn.c (_Unwind_DeleteException): New.
* config/nvptx/unwind-nvptx.c (_Unwind_DeleteException): Likewise.
(cherry picked from commit 815abd68353751d53ed9299e218f8ca1cc108d5f)
