Oops. The argument reduction routine doesn't like negative numbers, so make dd-%sin, dd-%cos, dd-%tan handle that.
Implement accurate arg reduction for the trig functions sin, cos, tan, using __kernel_rem_pio2. Use the accurate reduction in dd-%sin, dd-%cos, dd-%tan. The original version were renamed dd-%%sin, dd-%%cos, dd-%%tan because we still need them to evaluate the functions for small args. This also has the side effect that we don't signal overflow for moderately large args (~1w50) anymore.
Oops. Use 0d0 instead of 0w0 when creating a double-double-float in dd-cssqs.
compiler/float-tran.lisp: o Change the following functions to be maybe-inline instead of inline so we don't inline them by default unless the user says so by specifying (SPACE 0): ADD-DD, MUL-DD-D, MUL-DD, ADD-DD-D, SQR-DD, DIV-DD, DIV-DD-D, SQRT-DD code/irrat-dd.lisp: o Set (SPACE 0) for these functions so we inline the operations. (Should we really inline all of these?)
This large checkin merges the double-double float support to HEAD. The merge is from the tag "double-double-irrat-end". The double-double branch is now obsolete. The code should build without double-double support (tested on sparc) as well as build with double-double support (tested also on sparc).
file irrat-dd.lisp was initially added on branch double-double-array-branch.
