From 90e9955aef9fa64c3c9264d9ee046739cbce0c92 Mon Sep 17 00:00:00 2001 From: Srinath Parvathaneni Date: Fri, 31 Jan 2020 16:16:19 +0000 Subject: [PATCH] [ARM]: Add support for vldmia/vldmdb/vstmia/vstmdb instructions in MVE. This patch adds support for assembly instructions vldmia, vldmdb, vstmia and vstmdb in MVE. This instructions are already supported for Armv8-M Floating-point Extension. gas/ChangeLog: 2020-01-31 Srinath Parvathaneni * config/tc-arm.c (fldmias): Moved inside "THUMB_VARIANT & arm_ext_v6t2" to support VLDMIA instruction for MVE. (fldmdbs): Moved inside "THUMB_VARIANT & arm_ext_v6t2" to support VLDMDB instruction for MVE. (fstmias): Moved inside "THUMB_VARIANT & arm_ext_v6t2" to support VSTMIA instruction for MVE. (fstmdbs): Moved inside "THUMB_VARIANT & arm_ext_v6t2" to support VSTMDB instruction for MVE. * testsuite/gas/arm/mve-ldst.d: New test. * testsuite/gas/arm/mve-ldst.s: Likewise. --- gas/ChangeLog | 13 ++++++++++ gas/config/tc-arm.c | 10 +++++--- gas/testsuite/gas/arm/mve-ldst.d | 43 ++++++++++++++++++++++++++++++++ gas/testsuite/gas/arm/mve-ldst.s | 13 ++++++++++ 4 files changed, 75 insertions(+), 4 deletions(-) create mode 100644 gas/testsuite/gas/arm/mve-ldst.d create mode 100644 gas/testsuite/gas/arm/mve-ldst.s diff --git a/gas/ChangeLog b/gas/ChangeLog index d6c9eb61ce2..4ee4809e516 100644 --- a/gas/ChangeLog +++ b/gas/ChangeLog @@ -1,3 +1,16 @@ +2020-01-31 Srinath Parvathaneni + + * config/tc-arm.c (fldmias): Moved inside "THUMB_VARIANT & arm_ext_v6t2" + to support VLDMIA instruction for MVE. + (fldmdbs): Moved inside "THUMB_VARIANT & arm_ext_v6t2" to support VLDMDB + instruction for MVE. + (fstmias): Moved inside "THUMB_VARIANT & arm_ext_v6t2" to support VSTMIA + instruction for MVE. + (fstmdbs): Moved inside "THUMB_VARIANT & arm_ext_v6t2" to support VSTMDB + instruction for MVE. + * testsuite/gas/arm/mve-ldst.d: New test. + * testsuite/gas/arm/mve-ldst.s: Likewise. + 2020-01-31 Nick Clifton * po/fr.po: Updated French translation. diff --git a/gas/config/tc-arm.c b/gas/config/tc-arm.c index 16cbac4279e..3adc5707684 100644 --- a/gas/config/tc-arm.c +++ b/gas/config/tc-arm.c @@ -24989,6 +24989,12 @@ static const struct asm_opcode insns[] = mcCE(fstd, d000b00, 2, (RVD, ADDRGLDC), vfp_dp_ldst), mcCE(flds, d100a00, 2, (RVS, ADDRGLDC), vfp_sp_ldst), mcCE(fsts, d000a00, 2, (RVS, ADDRGLDC), vfp_sp_ldst), + + /* Memory operations. */ + mcCE(fldmias, c900a00, 2, (RRnpctw, VRSLST), vfp_sp_ldstmia), + mcCE(fldmdbs, d300a00, 2, (RRnpctw, VRSLST), vfp_sp_ldstmdb), + mcCE(fstmias, c800a00, 2, (RRnpctw, VRSLST), vfp_sp_ldstmia), + mcCE(fstmdbs, d200a00, 2, (RRnpctw, VRSLST), vfp_sp_ldstmdb), #undef THUMB_VARIANT /* Moves and type conversions. */ @@ -25003,17 +25009,13 @@ static const struct asm_opcode insns[] = cCE("fmxr", ee00a10, 2, (RVC, RR), rn_rd), /* Memory operations. */ -
