如何禁用有关无法确定堆栈大小的 ptxas 警告？
How can I disable the ptxas warning about indeterminable stack size?
在编译CUDA设备代码时，可能会报错（换行以方便阅读）：
ptxas warning : Stack size for entry function '_ZN7kernels11print_stuffIiEEvv'
cannot be statically determined
这可以 several reasons, like dynamic memory allocation or use of recursion, but those don't matter right now. I want to disable the warning, within some function at least. The thing is, I don't know which token to use to do so. It's no use searching this list (following the suggestion here SO 关于禁用特定警告）- 因为这些是 NVCC 的 C/C++ 前端中的警告，而不是汇编器中的警告。
那么我如何禁用此警告？
需要注意的重要一点是，这是一个 汇编程序 警告，因此 none 通常的前端警告抑制选项是相关的。
ptxas 仅支持非常有限的警告控制选项。在 CUDA 9 之前，仅支持以下内容：
--suppress-double-demote-warning (-suppress-double-demote-warning)
Suppress the warning that is otherwise emitted when a double precision instruction
is encountered in PTX that is targeted for an SM version that does not have
double precision support
--disable-warnings (-w)
Inhibit all warning messages.
--warn-on-double-precision-use (-warn-double-usage)
Warning if double(s) are used in an instruction.
--warn-on-local-memory-usage (-warn-lmem-usage)
Warning if local memory is used.
--warn-on-spills (-warn-spills)
Warning if registers are spilled to local memory.
--warning-as-error (-Werror)
Make all warnings into errors.
在你的情况下，唯一的选择是禁止显示所有警告。将 -Xptxas='-w' 添加到任何 nvcc 调用应该可以实现这一点。
CUDA 9 和更新版本添加了另一个选项 ptxas 来抑制您询问的警告：
--suppress-stack-size-warning (-suppress-stack-size-warning)
Suppress the warning that otherwise is printed when stack size cannot be
determined.
在这种情况下，将 -Xptxas='-suppress-stack-size-warning' 添加到任何 nvcc 调用应该消除警告。
