From f482d3044722558c3b16f54b33b0855bfbae36b1 Mon Sep 17 00:00:00 2001 From: Richard Sandiford Date: Fri, 24 Feb 2017 18:27:26 +0000 Subject: [AArch64] Add a "compnum" feature This patch adds a named "compnum" feature for the ARMv8.3-A FCADD and FCMLA extensions. include/ * opcode/aarch64.h (AARCH64_FEATURE_COMPNUM): New macro. (AARCH64_ARCH_V8_3): Include AARCH64_FEATURE_COMPNUM. opcodes/ * aarch64-tbl.h (aarch64_feature_simd_v8_3): Replace with... (aarch64_feature_compnum): ...this. (SIMD_V8_3): Replace with... (COMPNUM): ...this. (CNUM_INSN): New macro. (aarch64_opcode_table): Use it for the complex number instructions. gas/ * doc/c-aarch64.texi: Add a "compnum" entry. * config/tc-aarch64.c (aarch64_features): Likewise, * testsuite/gas/aarch64/advsimd-compnum.s: New test. * testsuite/gas/aarch64/advsimd-compnum.d: Likewise. --- gas/ChangeLog | 7 +++++ gas/config/tc-aarch64.c | 3 +++ gas/doc/c-aarch64.texi | 3 +++ gas/testsuite/gas/aarch64/advsimd-compnum.d | 40 +++++++++++++++++++++++++++++ gas/testsuite/gas/aarch64/advsimd-compnum.s | 9 +++++++ 5 files changed, 62 insertions(+) create mode 100644 gas/testsuite/gas/aarch64/advsimd-compnum.d create mode 100644 gas/testsuite/gas/aarch64/advsimd-compnum.s (limited to 'gas') diff --git a/gas/ChangeLog b/gas/ChangeLog index c40140f..9213740 100644 --- a/gas/ChangeLog +++ b/gas/ChangeLog @@ -1,3 +1,10 @@ +2017-02-24 Richard Sandiford + + * doc/c-aarch64.texi: Add a "compnum" entry. + * config/tc-aarch64.c (aarch64_features): Likewise, + * testsuite/gas/aarch64/advsimd-compnum.s: New test. + * testsuite/gas/aarch64/advsimd-compnum.d: Likewise. + 2017-02-24 Jan Beulich * testsuite/gas/i386/opcode.s: Add alternative TEST forms. diff --git a/gas/config/tc-aarch64.c b/gas/config/tc-aarch64.c index f8cda59..46b1e70 100644 --- a/gas/config/tc-aarch64.c +++ b/gas/config/tc-aarch64.c @@ -8438,6 +8438,9 @@ static const struct aarch64_option_cpu_value_table aarch64_features[] = { {"sve", AARCH64_FEATURE (AARCH64_FEATURE_SVE, 0), AARCH64_FEATURE (AARCH64_FEATURE_FP | AARCH64_FEATURE_SIMD, 0)}, + {"compnum", AARCH64_FEATURE (AARCH64_FEATURE_COMPNUM, 0), + AARCH64_FEATURE (AARCH64_FEATURE_F16 + | AARCH64_FEATURE_SIMD, 0)}, {"rcpc", AARCH64_FEATURE (AARCH64_FEATURE_RCPC, 0), AARCH64_ARCH_NONE}, {NULL, AARCH64_ARCH_NONE, AARCH64_ARCH_NONE}, diff --git a/gas/doc/c-aarch64.texi b/gas/doc/c-aarch64.texi index 59467c5..71d8072 100644 --- a/gas/doc/c-aarch64.texi +++ b/gas/doc/c-aarch64.texi @@ -131,6 +131,9 @@ automatically cause those extensions to be disabled. @multitable @columnfractions .12 .17 .17 .54 @headitem Extension @tab Minimum Architecture @tab Enabled by default @tab Description +@item @code{compnum} @tab ARMv8.2-A @tab ARMv8.3-A or later + @tab Enable the complex number SIMD extensions.
