(DW_FRAME_POINTER_REGNUM): New. (expand_builtin_init_dwarf_reg_sizes): Use unsigned for rnum. (def_cfa_1): Do not convert reg to DWARF_FRAME_REGNUM here. (dwf_regno): New. (dwarf2out_flush_queued_reg_saves, dwarf2out_frame_debug_def_cfa, dwarf2out_frame_debug_adjust_cfa, dwarf2out_frame_debug_cfa_register, dwarf2out_frame_debug_cfa_expression, dwarf2out_frame_debug_expr): Use it. * dwarf2out.c (based_loc_descr): Use dwarf_frame_regnum. * dwarf2out.h (dwarf_frame_regnum): New. (struct cfa_loc): Document the domain of the reg member. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@176178 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/dwarf2out.h | 10 ++++++++++ 1 file changed, 10 insertions(+) (limited to 'gcc/dwarf2out.h') diff --git a/gcc/dwarf2out.h b/gcc/dwarf2out.h index d41453bacea..912a100153a 100644 --- a/gcc/dwarf2out.h +++ b/gcc/dwarf2out.h @@ -121,6 +121,7 @@ dw_fde_node; typedef struct cfa_loc { HOST_WIDE_INT offset; HOST_WIDE_INT base_offset; + /* REG is in DWARF_FRAME_REGNUM space, *not* normal REGNO space. */ unsigned int reg; BOOL_BITFIELD indirect : 1; /* 1 if CFA is accessed via a dereference. */ BOOL_BITFIELD in_use : 1; /* 1 if a saved cfa is stored here. */ @@ -261,6 +262,15 @@ extern void dwarf2out_set_demangle_name_func (const char *(*) (const char *)); extern void dwarf2out_vms_debug_main_pointer (void); #endif +/* Unfortunately, DWARF_FRAME_REGNUM is not universally defined in such a + way as to force an unsigned return type.
