The latter is gone with 'ptxas' of, for example, CUDA 11.5 and later.
Pushed to trunk branch commit 84e90b69fba1cfa2a77942251ddfd0527fb22811
"nvptx: Re-enable "Stack alignment causes use of alloca" test cases", see
attached.

Subject: [PATCH] nvptx: Re-enable "Stack alignment causes use of alloca" test
cases
These generally PASS nowadays, without requiring 'alloca'.
There were two exceptions: 'gcc.dg/torture/stackalign/pr16660-2.c',
'gcc.dg/torture/stackalign/pr16660-3.c', where variants specifying
'-O0' or '-fpic' FAILed with 'ptxas' of, for example, CUDA 10.0 due to:
nvptx-as: ptxas terminated with signal 11 [Segmentation fault], core dumped
That however is gone with 'ptxas' of, for example, CUDA 11.5 and later.
gcc/testsuite/
* gcc.dg/torture/stackalign/global-1.c: Re-enable for nvptx.
* gcc.dg/torture/stackalign/inline-1.c: Likewise.
