2003-02-15 Roger Sayle <roger@eyesopen.com> * config/i386/i386.c (x86_ext_80387_constants): Use 80387 insns to load mathematical constants on K6, Athlon, Pentium 4 and PPro. (ext_80387_constants_table): Global table of 80387 special constants guarded by ext_80387_constants_init flag when not initialized. (init_ext_80387_constants): New function to initialize this table. (standard_80387_constant_p): Extend to recognize extra 80387 constants, in XFmode, on processors where this is a win. (standard_80387_constant_opcode): New function to return the opcode associated with standard_80387_constant_p. (standard_80387_constant_rtx): New function to return the XFmode CONST_DOUBLE associated with standard_80387_constant_p. (ix86_rtx_costs): Give the new constants the same cost as 1.0. * config/i386/i386-protos.h (standard_80387_constant_opcode): Prototype here. (standard_80387_constant_rtx): Likewise. * config/i386/i386.md (*movsf1, *movsf1_nointerunit, *movdf_nointeger, *movdf_integer, *movxf_nointeger, *movtf_nointeger, *movxf_integer, *movtf_integer): Simplify using new standard_80387_constant_opcode. * gcc.dg/i386-387-3.c: New test case.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs.html for how to report bugs usefully.
