2Subject: [patch] entry values: Fix resolving in inlined frames

36The problem is that DW_TAG_GNU_call_site <-> DW_OP_GNU_entry_value binding
37exists between DW_TAG_subprogram, nor DW_TAG_inlined_subroutine as described
38by Jakub Jelinek. This makes sense, when we look at DW_TAG_GNU_call_site and
39we just unwind the current inlined frame we get the same PC - this is no new
40information.
41
42TAILCALL_FRAME is a different case, while also an artificial frame the
43sequence cannot be determined at compile time and the binding
44DW_TAG_GNU_call_site <-> DW_OP_GNU_entry_value exists also for
45TAILCALL_FRAMEs.
46
47I will check it in.
48
49No regressions on {x86_64,x86_64-m32,i686}-fedora18-linux-gnu.

59 Fix entry values resolving in inlined frames.
60 * dwarf2loc.c (dwarf_expr_reg_to_entry_parameter): Move func_addr,
61 gdbarch and caller_frame initialization later. Skip INLINE_FRAME
62 entries of FRAME.
