Hello All:Please find the patch for the optimized usage of fint instruction changes. No regression is seen in the deja GNU tests. commit ed4dc0b96bf43c200cacad97f73a98ab7048e51b Author: Ajit Kumar Agarwal <ajitkum@xhdspdgnu.(none)> Date: Wed Feb 25 15:36:29 2015 +0530 [Patch,microblaze]: Optimized usage of fint instruction. The changes are made in the patch for optimized usage of fint instruction. The sequence of fint/cond_branch is replaced with fcmp/cond_branch. The fint instruction takes 6/7 cycles as compared to fcmp instruction which takes 1 cycles. The conversion from float to int with fint instruction is not required and can directly compared with fcmp instruction which takes 1 cycle as compared to 6/7 cycles with fint instruction. ChangeLog: 2015-02-25 Ajit Agarwal <ajit...@xilinx.com> * config/microblaze/microblaze.md (peephole2): New.
+ emit_insn (gen_cstoresf4 (comp_reg, operands[2], + gen_rtx_REG(SFmode,REGNO(cmp_op0)), + gen_rtx_REG(SFmode,REGNO(cmp_op1)))); Spaces before left parens and after comma in last two lines. -- Michael Eager ea...@eagercon.com 1960 Park Blvd., Palo Alto, CA 94306 650-325-8077
