yann@1625: 
yann@1625: Attached is a patch to add __attribute__ ((noinline)) to
yann@1625: call_gmon_start.
yann@1625: 
yann@1625: Without this patch, the sec script that processed initfini.s removes a
yann@1625: part of inlined call_gmon_start, causing undefined label errors.
yann@1625: 
yann@1625: This patch solves the problem by forcing gcc not to inline
yann@1625: call_gmon_start with __attribute__ ((noinline)).
yann@1625: 
yann@1625: Tested by building for arm-none-lixux-gnueabi.  OK to apply?
