I use git to clone the gcc source code from https://github.com/gcc-mirror/gcc.git, then use git log to check the committed version of gcc, finally used git reset to go back the old version. The problem is i can not find gcc version 10.0.0 20190503 (experimental) [trunk revision 270847] (GCC) in the git log.

Look for "From-SVN:" in git log.
