Subject: [PATCH 0/5] aarch64: Add ACLE intrinsics codegen support for lrcpc3 instructions
Date: Thu, 9 Nov 2023 14:12:43 +0000 [thread overview]
Message-ID: <20231109141300.3542453-1-victor.donascimento@arm.com> (raw)
Given the introduction of the third set of Release Consistency
processor consistent (RCpc) memory model-compliant instructions in
the form of FEAT_LRCPC3 as an optional extension from Armv8.2-a
onward, this patch series adds the RCPC3 ACLE Neon intrinsics,
thus enabling the use of the architectural feature in C.
These intrinsics enable the use of the new LDAP1 and STL1
instructions and are given single and twin-lane variants for unsigned,
signed and poly 64-bit values, in the form of the following
builtin-functions:
* vldap1_lane_{u|s|p}64
* vldap1q_lane_{u|s|p}64
* ldp1_lane_{u|s|p}64
* ldp1q_lane_{u|s|p}64
Bootstrapped and regression tested on aarch64-none-linux-gnu.
Victor Do Nascimento (5):
aarch64: rcpc3: Add +rcpc3 extension
aarch64: rcpc3: Add relevant iterators to handle Neon intrinsics
aarch64: rcpc3: Add Neon ACLE intrinsics
aarch64: rcpc3: add Neon ACLE wrapper functions to `arm_neon.h'
aarch64: rcpc3: Add intrinsics tests
