From 8f638e81e9d74eacb7b19c4350340605f703f38b Mon Sep 17 00:00:00 2001 From: Lioncash Date: Thu, 6 May 2021 19:18:11 -0400 Subject: ldr: Simplify memory copy within LoadNro() We can use the dedicated memory function for performing copies instead of reading into a temporary buffer and then immediately writing it back out to memory. Eliminates a bit of heap memory churn. --- src/core/hle/service/ldr/ldr.cpp | 8 +++----- 1 file changed, 3 insertions(+), 5 deletions(-) (limited to 'src/core/hle/service/ldr/ldr.cpp') diff --git a/src/core/hle/service/ldr/ldr.cpp b/src/core/hle/service/ldr/ldr.cpp index c8bc60ad1..89f6f6a2a 100644 --- a/src/core/hle/service/ldr/ldr.cpp +++ b/src/core/hle/service/ldr/ldr.cpp @@ -387,11 +387,9 @@ public: const VAddr bss_end_addr{ Common::AlignUp(bss_start + nro_header.bss_size, Kernel::PageSize)}; - auto CopyCode{[&](VAddr src_addr, VAddr dst_addr, u64 size) { - std::vector source_data(size); - system.Memory().ReadBlock(src_addr, source_data.data(), source_data.size()); - system.Memory().WriteBlock(dst_addr, source_data.data(), source_data.size()); - }}; + const auto CopyCode = [this, process](VAddr src_addr, VAddr dst_addr, u64 size) { + system.Memory().CopyBlock(*process, dst_addr, src_addr, size); + }; CopyCode(nro_addr + nro_header.segment_headers[TEXT_INDEX].memory_offset, text_start, nro_header.segment_headers[TEXT_INDEX].memory_size); CopyCode(nro_addr + nro_header.segment_headers[RO_INDEX].memory_offset, ro_start, -- cgit v1.2.3
