--- Comment #8 from Thomas Schwinge <tschwinge at gcc dot gnu.org> ---
With current GCC, for nvptx offloading, '-O0', we get for the "Reproducer"
(attached, also #c2):
reproducer.cpp:18:1: error: alias definitions not supported in this
configuration
18 | vector<sz>::vector(int const& init_val) {
| ^
nvptx mkoffload: fatal error:
build-gcc/gcc/x86_64-pc-linux-gnu-accel-nvptx-none-gcc returned 1 exit status
[...]
With either optimizations enabled, or '-O0' with additional
'-foffload-options=nvptx-none="-mptx=6.3 -malias"', compilation succeeds, and
we get the expected:
$ ./a.out
8
Therefore, this issue should (soon...) get resolved via PR105018 "[nvptx] Need
better alias support", and I'll make sure to include your test case, thanks!
