* config/mips/mips.h (ISA_HAS_EXTS): New macro. * config/mips/mips.md (*ashr_trunc<mode>): Name the pattern combining an arithmetic right shift by more than 31 and a trunction. Don't match for out-of-range shift amounts. Set attribute mode to <MODE>. (*lshr32_trunc<mode>): Name the pattern combining a logical right shift by 32 and and a truncation. Set attribute mode to <MODE>. (*<optab>_trunc<mode>_exts): New pattern for truncated right shifts by less than 32. (extv): Change predicate on first operand to accept registers. Change predicate of the other operands from immediate_operand to const_int_operand. Expand exts when source is a register. (extzv): Change predicate of the constant operands from immediate_operand to const_int_operand. (extzv<mode>): Change predicate of the constant operands from immediate_operand to const_int_operand and no constraint. Also remove mode. (*extzv_trunc<mode>_exts): New pattern. testsuite/ * gcc.target/mips/truncate-2.c: New test. * gcc.target/mips/octeon-exts-1.c: New test. * gcc.target/mips/octeon-exts-2.c: New test. * gcc.target/mips/octeon-exts-3.c: New test. * gcc.target/mips/octeon-exts-4.c: New test.

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.
