Here is a +general list of actions required to perform the merge: + +- Checkout recent GCC tree. +- Run merge.sh script from libsanitizer directory. +- Modify Makefile.am files into asan/tsan/lsan/ubsan/sanitizer_common/interception + directories if needed. In particular, you may need to add new source files + and remove old ones in source files list, add new flags to {C, CXX}FLAGS if + needed and update DEFS with new defined variables. +- Apply all needed GCC-specific patches to libsanitizer (note that some of + them might be already included to upstream). +- Apply all necessary compiler changes. Be especially careful here, you must + not break ABI between compiler and library. +- Modify configure.ac file if needed (e.g. if you need to add link against new + library for sanitizer lilbs). +- Remove unused (deleted by merge) files from all source and include + directories. Be especially careful with headers, because they aren't listed + in Makefiles explicitly. +- Regenerate configure script and all Makefiles by autoreconf. You should use + exactly the same autotools version as for other GCC directories (current + version is 2.64, https://www.gnu.org/software/automake/faq/autotools-faq.html + for details how to install/use it). +- Run regression testing on at least three platforms (e.g. x86-linux-gnu, + x86_64-linux-gnu, aarch64-linux-gnu). +- Run {A, UB}San bootstrap on at least three platforms. |
