From-SVN: r85465
2003-06-04builtins.c (dconstpi, dconste): New mathematical constants.Roger Sayle1-0/+6
* builtins.c (dconstpi, dconste): New mathematical constants. (init_builtin_dconsts): New function to initialize dconstpi and dconste. (fold_builtin): Optimize exp(1.0) = e. Evaluate exp(x) at compile time with -ffast-math when x is an integer constant. Optimize tan(0.0) = 0.0. Optimize atan(0.0) = 0.0, atan(1.0) = pi/4 and tan(atan(x)) = x with -ffast-math. * gcc.dg/builtins-2.c: Add tests for tan(atan(x)). * gcc.dg/builtins-3.c: Add tests for tan(0.0) and atan(0.0). * gcc.dg/builtins-7.c: Add tests for tan(atan(x)) == x. * gcc.dg/builtins-17.c: New test case. * gcc.dg/i386-387-4.c: New test case. * gcc.c-torture/execute/ieee/mzero4.c: New test case. From-SVN: r67438
2003-03-31emit-rtl.c (dconstm2, dconsthalf): New real constants.Roger Sayle1-0/+39
* emit-rtl.c (dconstm2, dconsthalf): New real constants. (init_emit_once): Initialize dconstm2 and dconsthalf here. * real.h (dconstm2, dconsthalf): Add prototypes here. * real.c (real_sqrt): Use dconsthalf rather than local copy. * builtins.c (fold_builtin): When optimizing sqrt(exp(x)) as exp(x/2.0) remember to fold the division if possible. Fold sin(0.0) as 0.0, cos(0.0) as 1.0, pow(x,1.0) as x, pow(x,-1.0) as 1.0/x, pow(x,2.0) as x*x, pow(x,-2.0) as 1.0/(x*x) and pow(x,0.5) as sqrt(x). * gcc.dg/builtins-3.c: Add new tests for sin and cos. * gcc.dg/builtins-7.c: New test case. * gcc.dg/builtins-8.c: New test case.
