[RFC v5 09/10] tests/tcg/multiarch: Add nativecall.c test |
Date: |
Fri, 25 Aug 2023 18:45:25 +0800 |
Introduce a new test for native calls to ensure their functionality.
The process involves cross-compiling the test cases, building them
as dynamically linked binaries, and running these binaries which
necessitates the addition of the appropriate interpreter prefix.
