el_segundo.s

GNU binutils是GNU交叉工具链中的一个源码包

# el_segundo.s
#
# Tests that we generate the right code for v5e instructions.
# This is not a functional test, although it can be linked.
# (The section at the rear is non-Coyanosa stuff for comparison.)
# To verify a compiler, do:
#	<gcc build area>/gcc/as el_segundo.s -o _temp.o
#	<gcc build area>/binutils/objdump -dr _temp.o >! _temp.d
#	diff _temp.d el_segundo.d
