Estimated hours taken: 0.1 Branches: main, release tests/hard_coded/float_consistency.m: Change calls to float./ to float.unchecked_quotient. This test case is meant to test compile-time evaluation of builtins. float./ hasn't been builtin for a while. This test case fails with --optimize-constant-propagation. tests/hard_coded/Mercury.options: Enable --optimize-constant-propagation for this test.

% This test case tests that the compiler's constant propagation for

% floating point division produce the same value as that produced

% by doing the division at runtime.

% This is a regression test; versions of the compiler prior to Nov 2002

% failed this test at -O3 and higher.
