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 <nmekala@xilinx.com> - - * config/microblaze/microblaze.md (sqrtdf2): New - pattern. - -Signed-off-by:Ajit Agarwal ajitkum@xilinx.com - Nagaraju Mekala nmekala@xilinx.com ---- - 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 3c80760..1fb5582 100644 ---- a/gcc/config/microblaze/microblaze.md -+++ b/gcc/config/microblaze/microblaze.md -@@ -451,6 +451,20 @@ - (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")))] --- -2.7.4 - |
