    • re PR tree-optimization/89437 (incorrect result for sinl (atanl (x))) · 5f054b17 
      Fix PR89437

Fix PR89437. Fix the sinatan-1.c testcase to not run without
a C99 target system.  Use nextafterl for long double initialization.

Fix an issue with sinl (atanl (sqrtl (LDBL_MAX)) returning 0.0
instead of 1.0 by using x < sqrtl (LDBL_MAX) in match.pd.

	PR tree-optimization/89437
	* match.pd: Use lt in sin(atan(x)) and cos(atan(x)) simplifications.

    testsuite/
	PR tree-optimization/89437
	* gcc.dg/sinatan-1.c: Fix testcase.
