* config/i386/i386.md (*fpatanxf3_i387, fpatan_extend<mode>xf3_i387): New insn patterns. (atan2sf3_1, atan2df3_1, atan2xf3_1): Remove insn patterns. (atan2xf3): Directly generate RTL pattern. (atan2<mode>3): Rename from atan2sf3 and atan2df3 and macroize insn patterns using X87MODEF12 mode macro. Use fpatan_extend<mode>xf3_i387 and truncate result to requested mode. Use SSE_FLOAT_MODE_P to disable patterns for SSE math. (atan<mode>2): Rename from atansf2 and atandf2 and macroize insn patterns using X87MODEF12 mode macro. Use fpatan_extend<mode>xf3_i387 and truncate result to requested mode. Use SSE_FLOAT_MODE_P to disable patterns for SSE math. From-SVN: r120950
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*.
