Espressif has forks of everything (OpenOCD, GDB, GCC) that they never mainline and that just become outdated as they release new chips.

The latest xtensa-esp8266-elf-gcc is version 5.2

Their first patches are in the process of being merged: https://discourse.llvm.org/t/rfc-request-for-upstream-tensil...
