Userland: Port UBSAN implementation to userspace Take Kernel/UBSanitizer.cpp and make a copy in LibSanitizer. We can use LibSanitizer to hold other sanitizers as people implement them :^). To enable UBSAN for LibC, DynamicLoader, and other low level system libraries, LibUBSanitizer is built as a serenity_libc, and has a static version for LibCStatic to use. The approach is the same as that taken in Note that this means now UBSAN is enabled for code generators, Lagom, Kernel, and Userspace with -DENABLE_UNDEFINED_SANTIZER=ON. In userspace however, UBSAN is not deadly (yet). Co-authored-by: ForLoveOfCats <ForLoveOfCats@vivaldi.net> 2021-05-24 04:40:22 +03:00			`set(SOURCES`

Meta+Userland: Add ENABLE_USERSPACE_COVERAGE_COLLECTION CMake option This option sets -fprofile-instr-generate -fcoverage-mapping for Clang builds only on almost all of Userland. Loader and LibTimeZone are exempt. This can be used for generating code coverage reports, or even PGO in the future. 2022-03-05 04:02:09 +03:00			`target_link_libraries(LibUBSanitizerStatic PRIVATE NoCoverage)`
