| //! containing an atomic snapshot at the point of this function’s return. This |
| //! function does not modify any registers. |
| //! |
| //! \param[out] cpu_context The structure to store the context in. |

| //! \note On x86_64, the value for `%%rdi` will be populated with the address of |
| //! this function’s argument, as mandated by the ABI. If the value of |
| //! `%%rdi` prior to calling this function is needed, it must be obtained |
| //! separately prior to calling this function. For example: |
| //! \code |
| //! uint64_t rdi; |
| //! asm("movq %%rdi, %0" : "=m"(rdi)); |
| //! \endcode |
