Ref: https://bugzilla.tianocore.org/show_bug.cgi?id=3704 build -a X64 -t CLANG38 -b RELEASE -p OvmfPkg/OvmfPkgX64.dsc results in UDK/MdeModulePkg/Library/UefiBootManagerLib/BmBoot.c:1284:31: error: variable 'Status' set but not used [-Werror,-Wunused-but-set-variable] Signed-off-by: Mikhail Krichanov <krichanov@ispras.ru> MdePkg/DebugLib(PerformanceLib): Fix "unused-but-set-variable" warning The current definitions of DEBUG_CODE_BEGIN() and DEBUG_CODE_END() use the local variable __DebugCodeLocal as an attempt to track parity. If DEBUG_CODE_END() is used without a preceding DEBUG_CODE_BEGIN(), __DebugCodeLocal will not have been declared and a compilation error will be issued. The mutations of the variable are not used to track nesting or such. As the value of this variable is never actually used, recent Clang versions issue a "unused-but-set-variable" warning for it. To solve this, re-define __DebugCodeLocal as a BOOLEAN that is always FALSE and use it in a do-while loop condition as done explicitly in many places. Like the previous solution, DEBUG_CODE_END() cannot be used without DEBUG_CODE_BEGIN(), as __DebugCodeLocal will be not have been defined. Signed-off-by: Marvin Häuser <mhaeuser@posteo.de>
