GCN, nvptx: Define '_Unwind_RaiseException', '_Unwind_Resume_or_Rethrow'
This resolves GCN:
ld: error: undefined symbol: _Unwind_RaiseException
>>> referenced by eh_throw.cc:93 ([...]/source-gcc/libstdc++-v3/libsupc++/eh_throw.cc:93)
>>> eh_throw.o:(__cxa_throw) in archive /srv/data/tschwinge/amd-instinct2/gcc/build/submit-light-target_gcn/build-gcc/amdgcn-amdhsa/gfx908/libstdc++-v3/src/.libs/libstdc++.a
[...]
collect2: error: ld returned 1 exit status
..., and/or:
ld: error: undefined symbol: _Unwind_Resume_or_Rethrow
>>> referenced by eh_throw.cc:129 ([...]/source-gcc/libstdc++-v3/libsupc++/eh_throw.cc:129)
>>> eh_throw.o:(__cxa_rethrow) in archive /srv/data/tschwinge/amd-instinct2/gcc/build/submit-light-target_gcn/build-gcc/amdgcn-amdhsa/gfx908/libstdc++-v3/src/.libs/libstdc++.a
[...]
collect2: error: ld returned 1 exit status
..., and nvptx:
unresolved symbol _Unwind_RaiseException
collect2: error: ld returned 1 exit status
..., or:
unresolved symbol _Unwind_Resume_or_Rethrow
collect2: error: ld returned 1 exit status
For both GCN, nvptx, this each progresses ~25 'check-gcc-c++',
and ~10 '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 some 'FAIL: [...] execution test' where these test cases now FAIL when
attempting to use these interfaces, or, if applicable, FAIL due to run-time
'GCC/nvptx: sorry, unimplemented: dynamic stack allocation not supported'.
libgcc/
* config/gcn/unwind-gcn.c (_Unwind_RaiseException)
(_Unwind_Resume_or_Rethrow): New.
* config/nvptx/unwind-nvptx.c (_Unwind_RaiseException)
(_Unwind_Resume_or_Rethrow): Likewise.
