From: "Edgar E. Iglesias" <edgar.igles...@amd.com> On the way towards Xen safety certification we're evaluating the use of tools to collect code-coverage/profiling information from execution traces. Some tools rely on ELF symbols for code being declared with type FUNC and having a symbol size.
We currently annotate some symbols but not all. Also, there seems to be different ways to do the annotation. This series now converts all the .S files under xen/arm/arm64 to use the macros from xen/linkage.h and also adds missing code symbol annotations for global symbols. There are still some local labels that are left unmodified. Best regards, Edgar ChangeLog: v3 -> v4: * Add newline between FUNC_LOCAL and PRINT_ID. * Use LABEL instead of GLOBAL in bpi.S. * Changed .global -> LABEL in entry.S (dropped Stefanos RB tag). v2 -> v3: * Convert and add annotations for all of xen/arm/arm64. * Fix commit message for entry.S. v1 -> v2: * Drop RFC. * Squash into a single patch to avoid confusion.
