From 5b112bcc0de7b4a815d91eda195177bab800acd3 Mon Sep 17 00:00:00 2001 From: Nico Weber Date: Sun, 13 Dec 2020 21:30:38 -0500 Subject: [PATCH] Revert "[JITLink] Add JITLinkDylib type, thread through JITLinkMemoryManager APIs." This reverts commit 8904ee8ac7ebcc50a60de0914abc6862e28b6664. Didn't `git add` llvm/ExecutionEngine/JITLink/JITLinkDylib.h and hence doesn't build anywhere. --- llvm/include/llvm/ExecutionEngine/JITLink/JITLink.h | 9 --------- .../llvm/ExecutionEngine/JITLink/JITLinkMemoryManager.h | 17 +++-------------- llvm/include/llvm/ExecutionEngine/Orc/Core.h | 4 +--- .../ExecutionEngine/Orc/OrcRPCTargetProcessControl.h | 3 +-- .../llvm/ExecutionEngine/Orc/OrcRemoteTargetClient.h | 3 +-- llvm/lib/ExecutionEngine/JITLink/JITLinkGeneric.cpp | 3 +-- .../ExecutionEngine/JITLink/JITLinkMemoryManager.cpp | 3 +-- llvm/lib/ExecutionEngine/Orc/ObjectLinkingLayer.cpp | 3 +-- llvm/lib/ExecutionEngine/Orc/TPCIndirectionUtils.cpp | 6 +++--- llvm/tools/llvm-jitlink/llvm-jitlink.cpp | 2 +- 10 files changed, 13 insertions(+), 40 deletions(-) diff --git a/llvm/include/llvm/ExecutionEngine/JITLink/JITLink.h b/llvm/include/llvm/ExecutionEngine/JITLink/JITLink.h index 48e6433..f0b4d9b 100644 --- a/llvm/include/llvm/ExecutionEngine/JITLink/JITLink.h +++ b/llvm/include/llvm/ExecutionEngine/JITLink/JITLink.h @@ -1270,15 +1270,9 @@ class JITLinkContext { public: using LookupMap = DenseMap; - /// Create a JITLinkContext. - JITLinkContext(const JITLinkDylib *JD) : JD(JD) {} - /// Destroy a JITLinkContext. virtual ~JITLinkContext(); - /// Return the JITLinkDylib that this link is targeting, if any. - const JITLinkDylib *getJITLinkDylib() const { return JD; } - /// Return the MemoryManager to be used for this link. virtual JITLinkMemoryManager &getMemoryManager() = 0; @@ -1330,9 +1324,6 @@ public: /// Called by JITLink to modify the pass pipeline prior to linking. /// The default version performs no modification. virtual Error modifyPassConfig(const Triple &TT, PassConfiguration &Config); - -private: - const JITLinkDylib *JD = nullptr; }; /// Marks all symbols in a graph live.
