From 5235b053b46769fd808974ef409e86df992fd051 Mon Sep 17 00:00:00 2001 From: Lioncash Date: Thu, 9 May 2019 18:59:47 -0400 Subject: video_core/memory_manager: Remove superfluous const from function declarations These are able to be omitted from the declaration of functions, since they don't do anything at the type system level. The definitions of the functions can retain the use of const though, since they make the variables immutable in the implementation of the function where they're used. --- src/video_core/memory_manager.h | 14 +++++++------- 1 file changed, 7 insertions(+), 7 deletions(-) (limited to 'src/video_core') diff --git a/src/video_core/memory_manager.h b/src/video_core/memory_manager.h index e4f0c4bd6..b9a683497 100644 --- a/src/video_core/memory_manager.h +++ b/src/video_core/memory_manager.h @@ -66,7 +66,7 @@ public: const u8* GetPointer(GPUVAddr addr) const; // Returns true if the block is continous in host memory, false otherwise - bool IsBlockContinous(const GPUVAddr start, const std::size_t size); + bool IsBlockContinous(GPUVAddr start, std::size_t size); /** * ReadBlock and WriteBlock are full read and write operations over virtual @@ -74,9 +74,9 @@ public: * in the Host Memory counterpart.
