Subject: RISC-V: Make riscv_isa_xlen a global function.
X-Git-Tag: users/ARM/embedded-binutils-master-2018q4~1130
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=411baa470ef354e50b488c0c736ac7af8d856ded;p=external%2Fbinutils.git

RISC-V: Make riscv_isa_xlen a global function.

This allows the function to be used from riscv OS files, which also need to
depend on XLEN size.

	gdb/
	* riscv-tdep.c (riscv_isa_xlen): Drop static.
	* riscv-tdep.h (riscv_isa_xlen): Add extern declaration.
