[BOLT] Adding a unittest that covers Arm SPE PBT aggregation (#160095) When the SPE Previous Branch Target address (FEAT_SPE_PBT) feature is available, an SPE sample by combining this PBT feature, has two entries. Arm SPE records SRC/DEST addresses of the latest sampled branch operation, and it stores into the first entry. PBT records the target address of most recently taken branch in program order before the sampled operation, it places into the second entry. They are formed a chain of two consecutive branches. Where: - The previous branch operation (PBT) is always taken. - In SPE entry, the current source branch (SRC) may be either fall-through or taken, and the target address (DEST) of the recorded branch operation is always what was architecturally executed. However PBT doesn't provide as much information as SPE does. It lacks those information such as the address of source branch, branch type, and prediction bit. These information are always filled with zero in PBT entry. Therefore Bolt cannot evaluate the prediction, and source branch fields, it leaves them zero during the aggregation process. Tests includes a fully expanded example. | 8 个月前 | |
[BOLT] Revise IDE folder structure (#89742) Update the folder titles for targets in the monorepository that have not seen taken care of for some time. These are the folders that targets are organized in Visual Studio and XCode ( set_property(TARGET <target> PROPERTY FOLDER "<title>")) when using the respective CMake's IDE generator. * Ensure that every target is in a folder * Use a folder hierarchy with each LLVM subproject as a top-level folder * Use consistent folder names between subprojects * When using target-creating functions from AddLLVM.cmake, automatically deduce the folder. This reduces the number of set_property/set_target_property, but are still necessary when add_custom_target, add_executable, add_library, etc. are used. A LLVM_SUBPROJECT_TITLE definition is used for that in each subproject's root CMakeLists.txt. | 2 年前 |
