CHANGES:beginner: :bulb: build.sh - Use BUILD_TYPE to control which feature will be deployed. - Wrong or unspecified will raise error. :bulb: CMakeLists.txt - New interface to control how the features about constraints dumping be deployed. - The code controlled by the newly added is all located in dfsan.cc :bulb: dfsan_flags.inc - Add new DFSan runtime flag to indicate where to dump the branch condition. - Considering its practical significance, it is not defined in sanitizer_flags.inc :bulb: dfsan.cc - Switch to using macro for controlling the feature. - Recover missing call of __sanitizer_set_*_path. Similar calls can be found in llvm-project at ubsan/ubsan_init.cpp, lsan/lsan.cpp, lsan/lsan.cpp, msan/msan.cpp, tsan/rtl/tsan_rtl.cpp and asan/asan_rtl.cpp, but are missing here. - Recover missing call of CacheBinaryName. The call is necessary otherwise GetProcessName always gives a "". :bulb: sanitizer_common.h - Declare ExtWrite defined in sanitizer_file.cc - Declare DmpExt defined in sanitizer_printf.cc :bulb: sanitizer_printf.cc - Define DmpExt to printf extra things needed. - Insert new parameter is_extra in SharedPrintfCode and SharedPrintfCodeNoBuffer for sharing some intermediate processes between DmpExt, Printf and Report. :bulb: sanitizer_file.cc :curly_loop: sanitizer_file.h - Just like an imitation show:neutral_face:. Add a new ReportFile object to provide an additional place for write extra things in. - Add __sanitizer_set_extfile_path for setting file path for the newly added. :bulb: sanitizer_interface_internal.h :curly_loop: sanitizer_common_interface.inc :curly_loop: common_interface_defs.h :curly_loop: libclang_rt.dfsan-x86_64.a.syms - Add necessary declaration and some docs just like __sanitizer_set_report_path :bulb: sanitizer_fuchsia.cc - Add __sanitizer_set_extfile_path here just because __sanitizer_set_report_path is here, too.
- README.md: A more useful version - build.sh: Move un-easy scripts outside and avoid accidental interruption due to missing sudo - install_llvm.sh: Use proper llvm version
