* config/mips/mips-protos.h (mips_output_conditional_branch): Change interface. (mips_output_order_conditional_branch): Declare. * config/mips/mips.h (MIPS_BRANCH): New macro. * config/mips/mips.c (gen_conditional_branch): Use VOIDmode for the comparison. Use gen_condjump. (mips_output_conditional_branch): Rework interface to take the asm templates for a direct branch and the inverse of a direct branch. (mips_output_order_conditional_branch): New function. (mips_builtin_branch_and_move): New function. (mips_expand_builtin_compare): Use it. Use VOIDmode for the branch condition. Use gen_single_cc as the condition for __builtin_mips_upper_* or __builtin_mips_lower_*. (mips_expand_builtin_bposge): Use mips_builtin_branch_and_move. Use VOIDmode for the branch condition. * config/mips/predicates.md (order_operator): New predicate. * config/mips/mips.md (UNSPEC_SINGLE_CC): New constant. (branch_fp): Rename to... (*branch_fp): ...this. Remove mode from comparison operator. Use new mips_output_conditional_branch interface. (branch_fp_inverted): Rename to... (*branch_fp_inverted): ...this and update as for *branch_fp. (*branch_zero<mode>): Rename to... (*branch_order<mode>): ...this. Remove mode from comparison operator. Use mips_output_order_conditional_branch. Only accept ordered comparisons. (*branch_zero<mode>_inverted): Rename to... (*branch_order<mode>_inverted): ...this and update as for *branch_order<mode>. (*branch_equality<mode>): Accept zero as the second operand to the equality operator. Use the new mips_output_conditional_branch interface. (*branch_equality<mode>_inverted): Likewise. (condjump): New expander. * config/mips/mips-dsp.md (mips_bposge): Remove mode from comparison operator. * config/mips/mips-ps-3d.md (bc1any4t, bc1any4f): Likewise. (bc1any2t, bc1any2f): Likewise. (single_cc): New expander. (*branch_upper_lower, *branch_upper_lower_inverted): New patterns. From-SVN: r111909 |

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.
