[PATCH 1/7] C-SKY: Add fpuv3 instructions and CK860 arch

gcc/ChangeLog: * config/csky/constraints.md ("W"): New constriant for mem operand with base reg, index register. ("Q"): Renamed and modified "csky_valid_fpuv2_mem_operand" to "csky_valid_mem_constraint_operand" to deal with both "Q" and "W" constraint.

[PATCH 5/7] C-SKY: Add insn "ldbs".

gcc/ChangeLog: config/csky/csky.md (cskyv2_sextend_ldbs): New insn. --- gcc/config/csky/csky.md | 10 ++ 1 file changed, 10 insertions(+) diff --git a/gcc/config/csky/csky.md b/gcc/config/csky/csky.md index 62875bf..ce9c252 100644 --- a/gcc/config/csky/csky.md +++ b/gcc/config/cs

[PATCH 3/7] C-SKY: Bug fix for bad setting of TARGET_DSP and TARGET_DIV.

gcc/ChangeLog: * config/csky/csky.c (csky_option_override): Init csky_arch_isa_features[] advanced, so TARGET_DSP and TARGET_DIV can be set well. --- gcc/config/csky/csky.c | 24 1 file changed, 12 insertions(+), 12 deletions(-) diff --git a/gcc/

[PATCH 6/7] C-SKY: Cases for csky fpuv3 instructions.

gcc/testsuite/ChangeLog: * gcc/testsuite/gcc.target/csky/fpuv3/fpuv3.exp: New. * gcc/testsuite/gcc.target/csky/fpuv3/fpv3_div.c: New. * gcc/testsuite/gcc.target/csky/fpuv3/fpv3_fadd.c: New. * gcc/testsuite/gcc.target/csky/fpuv3/fpv3_fdtos.c: New. * gcc/tests

[PATCH 4/7] C-SKY: Separate FRAME_POINTER_REGNUM into FRAME_POINTER_REGNUM and HARD_FRAME_POINTER_REGNUM.

gcc/ChangeLog: * config/csky/csky.h (FRAME_POINTER_REGNUM): Use HARD_FRAME_POINTER_REGNUM and FRAME_POINTER_REGNUM instead of the signle definition. The signle definition may not work well at simplify_subreg_regno(). (ELIMINABLE_REGS): Add for HARD_FRAME_POI

[PATCH 2/7] C-SKY: Delete LO_REGS and HI_REGS, use HILO_REGS instead.

gcc/ChangeLog: * config/csky/constraints.md ("l", "h"): Delete. * config/csky/csky.h (reg_class, REG_CLASS_NAMES, REG_CLASS_CONTENTS): Delete LO_REGS and HI_REGS. * config/csky/csky.c (regno_reg_classm, csky_secondary_reload, csky_register_move_cost):

[PATCH] C-SKY: Add fpuv3 instructions and CK860 arch
