From f0d70d8ee63b6f6a59cf4a10268f546b0bc80777 Mon Sep 17 00:00:00 2001 From: Victor Do Nascimento Date: Mon, 30 Oct 2023 12:39:28 +0000 Subject: [PATCH] aarch64: Add arch support for LSE128 extension Enable the `+lse128' feature modifier which, together with new internal feature flags, enables LSE128 instructions, which are represented via the new `_LSE128_INSN' macro. gas/ChangeLog: * config/tc-aarch64.c (aarch64_features): Add new "lse128" entry. include/ChangeLog: * include/opcode/aarch64.h (enum aarch64_feature_bit): New AARCH64_FEATURE_LSE128 feature bit. (enum aarch64_insn_class): New lse128_atomic instruction class. opcodes/ChangeLog: * opcodes/aarch64-tbl.h (aarch64_feature_lse128): New. (LSE128): Likewise. (_LSE128_INSN): Likewise. --- gas/config/tc-aarch64.c | 1 + gas/doc/c-aarch64.texi | 2 ++ include/opcode/aarch64.h | 3 +++ opcodes/aarch64-tbl.h | 5 +++++ 4 files changed, 11 insertions(+) diff --git a/gas/config/tc-aarch64.c b/gas/config/tc-aarch64.c index 4367455aa23..70c0ed652a5 100644 --- a/gas/config/tc-aarch64.c +++ b/gas/config/tc-aarch64.c @@ -10239,6 +10239,7 @@ static const struct aarch64_option_cpu_value_table aarch64_features[] = { AARCH64_FEATURE (SIMD)}, {"fp", AARCH64_FEATURE (FP), AARCH64_NO_FEATURES}, {"lse", AARCH64_FEATURE (LSE), AARCH64_NO_FEATURES}, + {"lse128", AARCH64_FEATURES (2, LSE, LSE128), AARCH64_NO_FEATURES}, {"simd", AARCH64_FEATURE (SIMD), AARCH64_FEATURE (FP)}, {"pan", AARCH64_FEATURE (PAN), AARCH64_NO_FEATURES}, {"lor", AARCH64_FEATURE (LOR), AARCH64_NO_FEATURES}, diff --git a/gas/doc/c-aarch64.texi b/gas/doc/c-aarch64.texi index 8af38f27320..81c18181831 100644 --- a/gas/doc/c-aarch64.texi +++ b/gas/doc/c-aarch64.texi @@ -265,6 +265,8 @@ automatically cause those extensions to be disabled. @tab Enable Guarded Control Stack Extension. @item @code{the} @tab ARMv8-A/Armv9-A @tab ARMv8.9-A/Armv9.4-A or later @tab Enable Translation Hardening extension. +@item @code{lse128} @tab Armv9.4-A @tab No + @tab Enable the 128-bit Atomic Instructions extension.
