From bf9a822b87ff362805ffefb8f76eea3c46f606a1 Mon Sep 17 00:00:00 2001 From: ReinUsesLisp Date: Wed, 5 Feb 2020 12:18:33 -0300 Subject: shader/decode: Fix constant buffer offsets Some instances were using cbuf34.offset instead of cbuf34.GetOffset(). This returned the an invalid offset. Address those instances and rename offset to "shifted_offset" to avoid future bugs. --- src/video_core/engines/shader_bytecode.h | 4 ++-- src/video_core/shader/decode/arithmetic_integer.cpp | 4 ++-- src/video_core/shader/decode/bfi.cpp | 2 +- 3 files changed, 5 insertions(+), 5 deletions(-) (limited to 'src/video_core') diff --git a/src/video_core/engines/shader_bytecode.h b/src/video_core/engines/shader_bytecode.h index 81b6d9eff..955f981bd 100644 --- a/src/video_core/engines/shader_bytecode.h +++ b/src/video_core/engines/shader_bytecode.h @@ -1657,11 +1657,11 @@ union Instruction { } xmad; union { - BitField<20, 14, u64> offset; + BitField<20, 14, u64> shifted_offset; BitField<34, 5, u64> index; u64 GetOffset() const { - return offset * 4; + return shifted_offset * 4; } } cbuf34; diff --git a/src/video_core/shader/decode/arithmetic_integer.cpp b/src/video_core/shader/decode/arithmetic_integer.cpp index e60875cc4..21366869d 100644 --- a/src/video_core/shader/decode/arithmetic_integer.cpp +++ b/src/video_core/shader/decode/arithmetic_integer.cpp @@ -166,13 +166,13 @@ u32 ShaderIR::DecodeArithmeticInteger(NodeBlock& bb, u32 pc) { const auto [op_rhs, test] = [&]() -> std::pair { switch (opcode->get().GetId()) { case OpCode::Id::ICMP_CR: - return {GetConstBuffer(instr.cbuf34.index, instr.cbuf34.offset), + return {GetConstBuffer(instr.cbuf34.index, instr.cbuf34.GetOffset()), GetRegister(instr.gpr39)}; case OpCode::Id::ICMP_R: return {GetRegister(instr.gpr20), GetRegister(instr.gpr39)}; case OpCode::Id::ICMP_RC: return {GetRegister(instr.gpr39), - GetConstBuffer(instr.cbuf34.index, instr.cbuf34.offset)}; + GetConstBuffer(instr.cbuf34.index, instr.cbuf34.GetOffset())}; case OpCode::Id::ICMP_IMM: return {Immediate(instr.alu.GetSignedImm20_20()), GetRegister(instr.gpr39)}; default: diff --git a/src/video_core/shader/decode/bfi.cpp b/src/video_core/shader/decode/bfi.cpp index f992bbe2a..70d1c055b 100644 --- a/src/video_core/shader/decode/bfi.cpp +++ b/src/video_core/shader/decode/bfi.cpp @@ -21,7 +21,7 @@ u32 ShaderIR::DecodeBfi(NodeBlock& bb, u32 pc) { switch (opcode->get().GetId()) { case OpCode::Id::BFI_RC: return {GetRegister(instr.gpr39), - GetConstBuffer(instr.cbuf34.index, instr.cbuf34.offset)}; + GetConstBuffer(instr.cbuf34.index, instr.cbuf34.GetOffset())}; case OpCode::Id::BFI_IMM_R: return {Immediate(instr.alu.GetSignedImm20_20()), GetRegister(instr.gpr39)}; default: -- cgit v1.2.3
