From: Sriram Raghunathan <[email protected]>
This patch removes the function_defer_statement, this is a feature
available in go and rust doesn't support this.
gcc/rust/ChangeLog:
* rust-backend.h (function_defer_statement): Remove.
* rust-gcc.cc (function_defer_statement): Remove.
Signed-off-by: Sriram Raghunathan <[email protected]>
Tested on x86_64-pc-linux-gnu.
