Package: src:gcc-11 Version: 11.1.0-3 GCC 11 run test timeout due to a problem of GDB on Cavium Octeon. Please drop build-dep on gdb on mipsel and mips64el. The problem is about a bug of Cavium Octeon: Sometimes, if there is a branch insn between ll and sc, the CPU may hang. I will continue to debug the problem.
