Richard Henderson 5bfd75a35c tcg/ppc: Revise goto_tb implementation ... Restrict the size of code_gen_buffer to 2GB on ppc64, which lets us assert that everything is reachable with addis+addi from tb_ret_addr. This lets us use a max of 4 insns for goto_tb instead of 7. Emit the indirect branch portion of goto_tb up front, which means we only have to update two insns to update any link. With a 64-bit store, we can update the link atomically, which may be required in future. Signed-off-by: Richard Henderson <rth@twiddle.net>		2015-10-19 11:04:37 -10:00
