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 8f9baec826b..986d9c3aa25 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")))] --- -2.17.1 - diff --git a/meta-xilinx/meta-microblaze/recipes-devtools/gcc/gcc-10/0018-PATCH-microblaze.md-Improve-adddi3-and-subdi3-insn-d.patch b/meta-xilinx/meta-microblaze/recipes-devtools/gcc/gcc-10/0018-PATCH-microblaze.md-Improve-adddi3-and-subdi3-insn-d.patch deleted file mode 100644 index 14095d833..000000000 --- a/meta-xilinx/meta-microblaze/recipes-devtools/gcc/gcc-10/0018-PATCH-microblaze.md-Improve-adddi3-and-subdi3-insn-d.patch +++ /dev/null @@ -1,63 +0,0 @@ -From a8c6c13cc322ecc300bb2cdf22e3d6f1680e56be Mon Sep 17 00:00:00 2001 -From: Mahesh Bodapati <mbodapat@xilinx.com> -Date: Tue, 17 Jan 2017 18:07:24 +0530 -Subject: [PATCH 18/54] [PATCH] microblaze.md: Improve 'adddi3' and 'subdi3' - insn definitions Change adddi3 to handle DI immediates as the second operand, - this requires modification to the output template however reduces the need to - specify seperate templates for 16-bit positive/negative immediate operands. - The use of 32-bit immediates for the addi and addic instructions is handled - by the assembler, which will emit the imm instructions when required.

Since we have a compiler -per mulitlib at this point that isn't an issue. - -The one problem is the target compiler is only going to work for the default multlilib at -this point. Ideally we'd figure out which multilibs were being enabled with which paths -and be able to patch these entries with a complete set of correct paths but this we -don't have such code at this point.
