# This test is a negative test for the altmacro expression.
# In this test we check the '.noaltmacro' directive.
# We expect that '.altmacro' and '.noaltmacro' will act as a switch on/off directives to the alternate macro mode.
# .noaltmacro returns the format into a regular macro handling.
# The default mode is ".noaltmacro" as first test checks.

# CHECK:  error: unknown token in expression
# CHECK-NEXT: addl $%(1%4), %eax
