From d72c809030ac74c532dd0126bf2ce7494a01cc9b Mon Sep 17 00:00:00 2001 From: Lioncash Date: Tue, 27 Nov 2018 13:52:13 -0500 Subject: [PATCH 1/2] file_sys/registered_cache: Use regular const references instead of std::shared_ptr for InstallEntry() These parameters don't need to utilize a shared lifecycle directly in the interface. Instead, the caller should provide a regular reference for the function to use. This also allows the type system to flag attempts to pass nullptr and makes it more generic, since it can now be used in contexts where a shared_ptr isn't being used (in other words, we don't constrain the usage of the interface to a particular mode of memory management). --- src/core/file_sys/registered_cache.cpp | 44 +++++++++++++------------- src/core/file_sys/registered_cache.h | 9 +++--- src/yuzu/main.cpp | 10 +++--- 3 files changed, 31 insertions(+), 32 deletions(-) diff --git a/src/core/file_sys/registered_cache.cpp b/src/core/file_sys/registered_cache.cpp index a3f8f2f737..07c3af64a5 100644 --- a/src/core/file_sys/registered_cache.cpp +++ b/src/core/file_sys/registered_cache.cpp @@ -381,22 +381,22 @@ std::vector RegisteredCache::ListEntriesFilter( return out;
