# This script verifies expression folding.
|
|
# It compiles a source file with '-fdebug-dump-symbols' and looks for
|
|
# parameter declarations to check they have been folded as expected.
|
|
# To check folding of an expression EXPR, the fortran program passed to this script
|
|
# must contain the following:
|
|
# logical, parameter :: test_x = <compare EXPR to expected value>
|
|
# This script will test that all parameter with a name starting with "test_" have
|
|
# been folded to .true.
|
|
# For instance, acos folding can be tested with:
|
|
#
|
|
# real(4), parameter :: res_acos = acos(0.5_4)
|
|
# real(4), parameter :: exp_acos = 1.047
|
|
# logical, parameter :: test_acos = abs(res_acos - exp_acos).LE.(0.001_4)
|
|
#
|
|
# There are two kinds of failure:
|
|
# - test_x is folded to .false.. This means the expression was folded
|
|
# but the value is not as expected.
|
|
# - test_x is not folded (it is neither .true. nor .false.). This means the
|
|
# compiler could not fold the expression.
