bfd/ * elf32-arm.c (elf32_arm_size_stubs): Use PLT address as destination for defined dynamic symbols when deciding whether to insert a stub or not. (allocate_dynrelocs): Make sure functions are not marked as Thumb when actually accessed through a PLT, even when generating a shared lib. ld/testsuite: * ld-arm/farcall-mixed-app.s: Add new references to check more modes switching. * ld-arm/farcall-mixed-lib1.s: Likewise. * ld-arm/farcall-mixed-app-v5.d: Update expected result. * farcall-mixed-app.d: Likewise. * ld-arm/farcall-mixed-lib.d: Likewise.
