From b0c92b80b156e75fcc5eedbbb8370fedd18b5ac4 Mon Sep 17 00:00:00 2001 From: Subv Date: Wed, 4 Jul 2018 15:25:48 -0500 Subject: GPU: Implemented the IMNMX shader instruction. It's similar to the FMNMX instruction but it works on integers. --- src/video_core/engines/shader_bytecode.h | 20 +++++++++++++++++--- 1 file changed, 17 insertions(+), 3 deletions(-) (limited to 'src/video_core/engines/shader_bytecode.h') diff --git a/src/video_core/engines/shader_bytecode.h b/src/video_core/engines/shader_bytecode.h index c1226a649..31684c410 100644 --- a/src/video_core/engines/shader_bytecode.h +++ b/src/video_core/engines/shader_bytecode.h @@ -194,6 +194,13 @@ enum class UniformType : u64 { Double = 5, }; +enum class IMinMaxExchange : u64 { + None = 0, + XLo = 1, + XMed = 2, + XHi = 3, +}; + union Instruction { Instruction& operator=(const Instruction& instr) { value = instr.value; @@ -278,6 +285,13 @@ union Instruction { BitField<49, 1, u64> negate_a; } alu_integer; + union { + BitField<39, 3, u64> pred; + BitField<42, 1, u64> negate_pred; + BitField<43, 2, IMinMaxExchange> exchange; + BitField<48, 1, u64> is_signed; + } imnmx; + union { BitField<54, 1, u64> saturate; BitField<56, 1, u64> negate_a; @@ -682,9 +696,9 @@ private: INST("0100110001100---", Id::FMNMX_C, Type::Arithmetic, "FMNMX_C"), INST("0101110001100---", Id::FMNMX_R, Type::Arithmetic, "FMNMX_R"), INST("0011100-01100---", Id::FMNMX_IMM, Type::Arithmetic, "FMNMX_IMM"), - INST("0100110000100---", Id::IMNMX_C, Type::Arithmetic, "FMNMX_IMM"), - INST("0101110000100---", Id::IMNMX_R, Type::Arithmetic, "FMNMX_IMM"), - INST("0011100-00100---", Id::IMNMX_IMM, Type::Arithmetic, "FMNMX_IMM"), + INST("0100110000100---", Id::IMNMX_C, Type::ArithmeticInteger, "IMNMX_C"), + INST("0101110000100---", Id::IMNMX_R, Type::ArithmeticInteger, "IMNMX_R"), + INST("0011100-00100---", Id::IMNMX_IMM, Type::ArithmeticInteger, "IMNMX_IMM"), INST("0100110000000---", Id::BFE_C, Type::Bfe, "BFE_C"), INST("0101110000000---", Id::BFE_R, Type::Bfe, "BFE_R"), INST("0011100-00000---", Id::BFE_IMM, Type::Bfe, "BFE_IMM"), -- cgit v1.2.3
