The powerpc optimization to provide a fast stacktrace requires some ad-hoc code to handle Linux signal frames and the change is fragile once the kernel decides to slight change its execution sequence [1]. The generic implementation work as-is and it should be future proof since the kernel provides the expected CFI directives in vDSO shared page. Checked on powerpc-linux-gnu, powerpc64le-linux-gnu, and powerpc64-linux-gnu. [1] https://sourceware.org/pipermail/libc-alpha/2021-January/122027.html |
