Subject: aarch64: Add SEH to machine_function
X-Git-Tag: basepoints/gcc-16~9259

aarch64: Add SEH to machine_function

SEH is not enabled in aarch64-w64-mingw32 target yet. However, it is
needed to be declared in machine_function for reusing winnt.cc.

gcc/ChangeLog:

	* config/aarch64/aarch64.h (struct seh_frame_state): Declare SEH
	structure in machine_function.
	(GTY): Add SEH field.
