-Subject: [PATCH] Add target hook to override DWARF2 frame register size
-
-gcc/
-
-        * target.def (TARGET_DWARF_FRAME_REG_MODE): New target hook.
-        * targhooks.c (default_dwarf_frame_reg_mode): New function.
-        * targhooks.h (default_dwarf_frame_reg_mode): New prototype.
-        * doc/tm.texi.in (TARGET_DWARF_FRAME_REG_MODE): Document.
-        * doc/tm.texi: Regenerate.
-        * dwarf2cfi.c (expand_builtin_init_dwarf_reg_sizes): Abstract mode
-        selection logic to default_dwarf_frame_reg_mode.
