-fpatchable-function-entry flag

Hello guys.
GCC has a flag -fpatchable-function-entry=N[,M]
https://gcc.gnu.org/onlinedocs/gcc/Instrumentation-Options.html

(at the bottom of the page).
Could you tell please, is there something similar in the clang? Or is these a plan to support this gcc option in clang?
Thank you very much!
