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. This conveniently handles the optimizable -cases where the immediate constant value does not need the higher half -words of the operands upper/lower words. - -Change the constraints of the subdi3 instruction definition such that it -does not match the second operand as an immediate value. This is because -there is no definition to handle this case nor is it possible to -implement purely with instructions as microblaze does not provide an -instruction to perform a forward arithmetic subtraction (it only -provides reverse 'rD = IMM - rA'). - -Signed-off-by: Nathan Rossi <nathan@nathanrossi.com> -Upstream-Status: Unsubmitted ---- - gcc/config/microblaze/microblaze.md | 13 ++++++------- - 1 file changed, 6 insertions(+), 7 deletions(-) - -diff --git a/gcc/config/microblaze/microblaze.md b/gcc/config/microblaze/microblaze.md -index b3a0011fd7..8a372d7ebb 100644 ---- a/gcc/config/microblaze/microblaze.md -+++ b/gcc/config/microblaze/microblaze.md -@@ -483,17 +483,16 @@ - ;; Adding 2 DI operands in register or reg/imm - - (define_insn "adddi3" -- [(set (match_operand:DI 0 "register_operand" "=d,d,d") -- (plus:DI (match_operand:DI 1 "register_operand" "%d,d,d") -- (match_operand:DI 2 "arith_operand32" "d,P,N")))] -+ [(set (match_operand:DI 0 "register_operand" "=d,d") -+ (plus:DI (match_operand:DI 1 "register_operand" "%d,d") -+ (match_operand:DI 2 "arith_operand" "d,i")))] - "" - "@ - add\t%L0,%L1,%L2\;addc\t%M0,%M1,%M2 -- addi\t%L0,%L1,%2\;addc\t%M0,%M1,r0 -- addi\t%L0,%L1,%2\;addc\t%M0,%M1,r0\;addi\t%M0,%M0,-1" -+ addi\t%L0,%L1,%j2\;addic\t%M0,%M1,%h2" - [(set_attr "type" "darith") - (set_attr "mode" "DI") -- (set_attr "length" "8,8,12")]) -+ (set_attr "length" "8,8")]) - - ;;---------------------------------------------------------------- - ;; Subtraction -@@ -530,7 +529,7 @@ - (define_insn "subdi3" - [(set (match_operand:DI 0 "register_operand" "=&d") - (minus:DI (match_operand:DI 1 "register_operand" "d") -- (match_operand:DI 2 "arith_operand32" "d")))] -+ (match_operand:DI 2 "register_operand" "d")))] - "" - "rsub\t%L0,%L2,%L1\;rsubc\t%M0,%M2,%M1" - [(set_attr "type" "darith") --- -2.14.2 - |
