The changes are made in the patch for -the inline expansion of the fsqrt builtin with fqrt instruction. The -sqrt math function takes double as argument and return double as -argument. The pattern is selected while expanding the unary op through -expand_unop which passes DFmode and the DFmode pattern was not there -returning zero. Thus the sqrt math function is not inlined and expanded. -The pattern with DFmode argument is added. Also the source and -destination argument is not same the DF through two different -consecutive registers with lower 32 bit is the argument passed to sqrt -and the higher 32 bit is zero. If the source and destinations are -different the DFmode 64 bits registers is not set properly giving the -problem in runtime. Such changes are taken care in the implementation of -the pattern for DFmode for inline expansion of the sqrt. - -ChangeLog: - -2015-06-16 Ajit Agarwal <ajitkum@xilinx.com> - Nagaraju Mekala <nagaraju.mekala@xilinx.com> - - * config/microblaze/microblaze.md (sqrtdf2): New - pattern. - -Signed-off-by: Nagaraju Mekala <nagaraju.mekala@xilinx.com> -Signed-off-by: Ajit Agarwal <ajitkum@xilinx.com> -Signed-off-by: Mahesh Bodapati <mbodapat@xilinx.com> -Signed-off-by: Manjukumar Matha <manjukumar.harthikote-matha@xilinx.com> -Upstream-Status: Pending ---- - gcc/config/microblaze/microblaze.md | 14 ++++++++++++++ - 1 file changed, 14 insertions(+) - -diff --git a/gcc/config/microblaze/microblaze.md b/gcc/config/microblaze/microblaze.md -index a3954a24b6..13f8803428 100644 ---- a/gcc/config/microblaze/microblaze.md -+++ b/gcc/config/microblaze/microblaze.md -@@ -449,6 +449,20 @@ - (set_attr "mode" "SF") - (set_attr "length" "4")]) - -+(define_insn "sqrtdf2" -+ [(set (match_operand:DF 0 "register_operand" "=d") -+ (sqrt:DF (match_operand:DF 1 "register_operand" "dG")))] -+ "TARGET_HARD_FLOAT && TARGET_FLOAT_SQRT" -+ { -+ if (REGNO (operands[0]) == REGNO (operands[1])) -+ return "fsqrt\t%0,%1"; -+ else -+ return "fsqrt\t%0,%1\n\taddk\t%D0,%D1,r0"; -+ } -+ [(set_attr "type" "fsqrt") -+ (set_attr "mode" "SF") -+ (set_attr "length" "4")]) -+ - (define_insn "fix_truncsfsi2" - [(set (match_operand:SI 0 "register_operand" "=d") - (fix:SI (match_operand:SF 1 "register_operand" "d")))] --- -2.14.2 - |
