From 536fc7f0ea77e08d68c760f387c307d258804e3b Mon Sep 17 00:00:00 2001 From: Lioncash Date: Tue, 26 Nov 2019 14:10:49 -0500 Subject: core: Prepare various classes for memory read/write migration Amends a few interfaces to be able to handle the migration over to the new Memory class by passing the class by reference as a function parameter where necessary. Notably, within the filesystem services, this eliminates two ReadBlock() calls by using the helper functions of HLERequestContext to do that for us. --- src/core/arm/arm_interface.cpp | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) (limited to 'src/core/arm/arm_interface.cpp') diff --git a/src/core/arm/arm_interface.cpp b/src/core/arm/arm_interface.cpp index 372612c9b..dea192869 100644 --- a/src/core/arm/arm_interface.cpp +++ b/src/core/arm/arm_interface.cpp @@ -13,7 +13,6 @@ #include "core/memory.h" namespace Core { - namespace { constexpr u64 ELF_DYNAMIC_TAG_NULL = 0; @@ -156,7 +155,7 @@ std::vector ARM_Interface::GetBacktrace() const { } std::map modules; - auto& loader{System::GetInstance().GetAppLoader()}; + auto& loader{system.GetAppLoader()}; if (loader.ReadNSOModules(modules) != Loader::ResultStatus::Success) { return {}; } -- cgit v1.2.3 From b05bfc603689419dc515a656b9fc711d79994f13 Mon Sep 17 00:00:00 2001 From: Lioncash Date: Tue, 26 Nov 2019 16:29:34 -0500 Subject: core/memory: Migrate over Read{8, 16, 32, 64, Block} to the Memory class With all of the trivial parts of the memory interface moved over, we can get right into moving over the bits that are used. Note that this does require the use of GetInstance from the global system instance to be used within hle_ipc.cpp and the gdbstub. This is fine for the time being, as they both already rely on the global system instance in other functions. These will be removed in a change directed at both of these respectively. For now, it's sufficient, as it still accomplishes the goal of de-globalizing the memory code. --- src/core/arm/arm_interface.cpp | 24 ++++++++++++------------ 1 file changed, 12 insertions(+), 12 deletions(-) (limited to 'src/core/arm/arm_interface.cpp') diff --git a/src/core/arm/arm_interface.cpp b/src/core/arm/arm_interface.cpp index dea192869..7e846ddd5 100644 --- a/src/core/arm/arm_interface.cpp +++ b/src/core/arm/arm_interface.cpp @@ -60,15 +60,15 @@ static_assert(sizeof(ELFSymbol) == 0x18, "ELFSymbol has incorrect size."); using Symbols = std::vector>; -Symbols GetSymbols(VAddr text_offset) { - const auto mod_offset = text_offset + Memory::Read32(text_offset + 4); +Symbols GetSymbols(VAddr text_offset, Memory::Memory& memory) { + const auto mod_offset = text_offset + memory.Read32(text_offset + 4); if (mod_offset < text_offset || (mod_offset & 0b11) != 0 || - Memory::Read32(mod_offset) != Common::MakeMagic('M', 'O', 'D', '0')) { + memory.Read32(mod_offset) != Common::MakeMagic('M', 'O', 'D', '0')) { return {}; } - const auto dynamic_offset = Memory::Read32(mod_offset + 0x4) + mod_offset; + const auto dynamic_offset = memory.Read32(mod_offset + 0x4) + mod_offset; VAddr string_table_offset{}; VAddr symbol_table_offset{}; @@ -76,8 +76,8 @@ Symbols GetSymbols(VAddr text_offset) { VAddr dynamic_index = dynamic_offset; while (true) { - const auto tag = Memory::Read64(dynamic_index); - const auto value = Memory::Read64(dynamic_index + 0x8); + const u64 tag = memory.Read64(dynamic_index); + const u64 value = memory.Read64(dynamic_index + 0x8); dynamic_index += 0x10; if (tag == ELF_DYNAMIC_TAG_NULL) { @@ -105,11 +105,11 @@ Symbols GetSymbols(VAddr text_offset) { VAddr symbol_index = symbol_table_address; while (symbol_index < string_table_address) { ELFSymbol symbol{}; - Memory::ReadBlock(symbol_index, &symbol, sizeof(ELFSymbol)); + memory.ReadBlock(symbol_index, &symbol, sizeof(ELFSymbol)); VAddr string_offset = string_table_address + symbol.name_index; std::string name; - for (u8 c = Memory::Read8(string_offset); c != 0; c = Memory::Read8(++string_offset)) { + for (u8 c = memory.Read8(string_offset); c != 0; c = memory.Read8(++string_offset)) { name += static_cast(c); } @@ -141,17 +141,17 @@ constexpr u64 SEGMENT_BASE = 0x7100000000ull; std::vector ARM_Interface::GetBacktrace() const { std::vector out; + auto& memory = system.Memory(); auto fp = GetReg(29); auto lr = GetReg(30); - while (true) { out.push_back({"", 0, lr, 0}); if (!fp) { break; } - lr = Memory::Read64(fp + 8) - 4; - fp = Memory::Read64(fp); + lr = memory.Read64(fp + 8) - 4; + fp = memory.Read64(fp); } std::map modules; @@ -162,7 +162,7 @@ std::vector ARM_Interface::GetBacktrace() const { std::map symbols; for (const auto& module : modules) { - symbols.insert_or_assign(module.second, GetSymbols(module.first)); + symbols.insert_or_assign(module.second, GetSymbols(module.first, memory)); } for (auto& entry : out) { -- cgit v1.2.3
