+/*!
+
+Tests the extent to which frame pointers can be controlled by the CLI.
+The behavior of our frame pointer options, at present, is an irreversible ratchet, where
+a "weaker" option that allows omitting frame pointers may be overridden by the target demanding
+that all code (or all non-leaf code, more often) must be compiled with frame pointers.
+This was discussed on 2025-05-22 in the T-compiler meeting and accepted as an intentional change,
+ratifying the prior decisions by compiler contributors and reviewers as correct,
+though it was also acknowledged that the flag allows somewhat confusing inputs.
+
+We find aarch64-apple-darwin useful because of its icy-clear policy regarding frame pointers,
+e.g. <https://developer.apple.com/documentation/xcode/writing-arm64-code-for-apple-platforms> says:
+
+* The frame pointer register (x29) must always address a valid frame record. Some functions —
+  such as leaf functions or tail calls — may opt not to create an entry in this list.
+  As a result, stack traces are always meaningful, even without debug information.
+
+Many Rust fn, if externally visible, may be expected to follow target ABI by tools or asm code!
+This can make it a problem to generate ABI-incorrect code, which may mean "with frame pointers".
+For this and other reasons, `-Cforce-frame-pointers=off` cannot override the target definition.
+This can cause some confusion because it is "reverse polarity" relative to C compilers, which have
+commands like `-fomit-frame-pointer`, `-fomit-leaf-frame-pointer`, or `-fno-omit-frame-pointer`!
+
+Specific cases where platforms or tools rely on frame pointers for sound or correct unwinding:
