     4 Attached is a patch to add __attribute__ ((noinline)) to
     5 call_gmon_start.
     6 
     7 Without this patch, the sec script that processed initfini.s removes a
     8 part of inlined call_gmon_start, causing undefined label errors.
     9 
    10 This patch solves the problem by forcing gcc not to inline
    11 call_gmon_start with __attribute__ ((noinline)).
    12 
    13 Tested by building for arm-none-lixux-gnueabi.  OK to apply?
