Hi all,
Is there a way to control how clang/LLVM outputs DWARF call frame information? In particular, is there a way to specify that the calculation of the the canonical frame address (CFA) should always use the stack pointer instead of the frame pointer? Specifying “-fomit-frame-pointer” seems to force this behavior on x86-64, but it doesn’t have the same effect for AArch64 (in fact, it looks like this optimization is not fully implemented on AArch64).
