From 9bae37ec8dc32027dedf9a32bf15754ebad6da38 Mon Sep 17 00:00:00 2001 From: Christophe Lyon Date: Mon, 14 Aug 2023 13:07:12 +0000 Subject: [PATCH] arm: [MVE intrinsics] add support for p8 and p16 polynomial types Although they look like aliases for u8 and u16, we need to define them so that we can handle p8 and p16 suffixes with the general framework. They will be used by vmull[bt]q_poly intrinsics. 2023-08-14 Christophe Lyon gcc/ * config/arm/arm-mve-builtins.cc (type_suffixes): Handle poly_p field.. (TYPES_poly_8_16): New. (poly_8_16): New. * config/arm/arm-mve-builtins.def (p8): New type suffix. (p16): Likewise. * config/arm/arm-mve-builtins.h (enum type_class_index): Add TYPE_poly. (struct type_suffix_info): Add poly_p field. --- gcc/config/arm/arm-mve-builtins.cc | 6 ++++++ gcc/config/arm/arm-mve-builtins.def | 2 ++ gcc/config/arm/arm-mve-builtins.h | 5 ++++- 3 files changed, 12 insertions(+), 1 deletion(-) diff --git a/gcc/config/arm/arm-mve-builtins.cc b/gcc/config/arm/arm-mve-builtins.cc index 7eec9d2861c9..fa8b0ad36b3a 100644 --- a/gcc/config/arm/arm-mve-builtins.cc +++ b/gcc/config/arm/arm-mve-builtins.cc @@ -128,6 +128,7 @@ CONSTEXPR const type_suffix_info type_suffixes[NUM_TYPE_SUFFIXES + 1] = { TYPE_##CLASS == TYPE_signed || TYPE_##CLASS == TYPE_unsigned, \ TYPE_##CLASS == TYPE_unsigned, \ TYPE_##CLASS == TYPE_float, \ + TYPE_##CLASS == TYPE_poly, \ 0, \ MODE }, #include "arm-mve-builtins.def" @@ -177,6 +178,10 @@ CONSTEXPR const type_suffix_info type_suffixes[NUM_TYPE_SUFFIXES + 1] = { #define TYPES_all_signed(S, D) \ S (s8), S (s16), S (s32) +/* _p8 _p16. */ +#define TYPES_poly_8_16(S, D) \ + S (p8), S (p16) + /* _u8 _u16 _u32. */ #define TYPES_all_unsigned(S, D) \ S (u8), S (u16), S (u32) @@ -275,6 +280,7 @@ DEF_MVE_TYPES_ARRAY (integer_8); DEF_MVE_TYPES_ARRAY (integer_8_16); DEF_MVE_TYPES_ARRAY (integer_16_32); DEF_MVE_TYPES_ARRAY (integer_32); +DEF_MVE_TYPES_ARRAY (poly_8_16); DEF_MVE_TYPES_ARRAY (signed_16_32); DEF_MVE_TYPES_ARRAY (signed_32); DEF_MVE_TYPES_ARRAY (reinterpret_integer); diff --git a/gcc/config/arm/arm-mve-builtins.def b/gcc/config/arm/arm-mve-builtins.def index e3f378762104..e2cf1baf370d 100644 --- a/gcc/config/arm/arm-mve-builtins.def +++ b/gcc/config/arm/arm-mve-builtins.def @@ -63,6 +63,8 @@ DEF_MVE_TYPE_SUFFIX (u8, uint8x16_t, unsigned, 8, V16QImode) DEF_MVE_TYPE_SUFFIX (u16, uint16x8_t, unsigned, 16, V8HImode) DEF_MVE_TYPE_SUFFIX (u32, uint32x4_t, unsigned, 32, V4SImode) DEF_MVE_TYPE_SUFFIX (u64, uint64x2_t, unsigned, 64, V2DImode) +DEF_MVE_TYPE_SUFFIX (p8, uint8x16_t, poly, 8, V16QImode) +DEF_MVE_TYPE_SUFFIX (p16, uint16x8_t, poly, 16, V8HImode) #undef REQUIRES_FLOAT #define REQUIRES_FLOAT true diff --git a/gcc/config/arm/arm-mve-builtins.h b/gcc/config/arm/arm-mve-builtins.h index c9b51a0c77bc..37b8223dfb27 100644 --- a/gcc/config/arm/arm-mve-builtins.h +++ b/gcc/config/arm/arm-mve-builtins.h @@ -146,6 +146,7 @@ enum type_class_index TYPE_float, TYPE_signed, TYPE_unsigned, + TYPE_poly, NUM_TYPE_CLASSES }; @@ -221,7 +222,9 @@ struct type_suffix_info unsigned int unsigned_p : 1; /* True if the suffix is for a floating-point type. */ unsigned int float_p : 1; - unsigned int spare : 13; + /* True if the suffix is for a polynomial type. */ + unsigned int poly_p : 1; + unsigned int spare : 12; /* The associated vector or predicate mode. */ machine_mode vector_mode : 16; -- 2.47.2
