Similarly, there are some sigcontextinfo.h macros that are used nowhere in glibc - ADVANCE_STACK_FRAME and FIRST_FRAME_POINTER were used in the old debug/backtrace.c, while SIGCONTEXT_EXTRA_ARGS, GET_FRAME, GET_STACK and CALL_SIGHANDLER were unused even before the removal of that old implementation (beyond uses of SIGCONTEXT_EXTRA_ARGS in definitions of CALL_SIGHANDLER). This patch removes all the unused frame.h headers and definitions of those macros. Tested with build-many-glibcs.py. 2018-03-21 Joseph Myers * sysdeps/generic/frame.h: Remove file. * sysdeps/arm/frame.h: Likewise. * sysdeps/hppa/frame.h: Likewise. * sysdeps/generic/sigcontextinfo.h (SIGCONTEXT_EXTRA_ARGS): Remove macro.
