We've fixed mixed mode jstack for the debuggee running with `-Xcomp` in [JDK-8370176](https://bugs.openjdk.org/browse/JDK-8370176), but it was not enough. We need to handle like unifying `CFrame` and `Frame` in stack unwinding as possible, and need to change how to get caller SP/FP from stack.
This PR works fine on both Linux AMD64 and Linux AArch64. All of `hotspot/jtreg/serviceability/sa` tests have been passed on both platforms. Big thanks to @pchilano for your help! ------------- Commit messages: - 8371194: serviceability/sa/TestJhsdbJstackMixedWithXComp.java failing Changes: https://git.openjdk.org/jdk/pull/28284/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=28284&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8371194 Stats: 230 lines in 10 files changed: 117 ins; 39 del; 74 mod Patch: https://git.openjdk.org/jdk/pull/28284.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/28284/head:pull/28284 PR: https://git.openjdk.org/jdk/pull/28284
