commit 88dfca6c43c11dea69db24cfb87e6821e63e29b2
Author: Ulrich Weigand <ulrich.weigand@de.ibm.com>
Date: Tue Sep 6 17:26:32 2016 +0200
Add some missing arch_..._type helpers
gdbtypes provides a number of helper routines that can be called instead of
using arch_type directly to create a type of a particular kind. This patch
adds two additional such routines that have been missing so far, to allow
creation of TYPE_CODE_DECFLOAT and TYPE_CODE_POINTER types.
The patch also changes a number of places to use the new helper routines
instead of calling arch_type directly. No functional change intended.
gdb/ChangeLog:
* gdbtypes.h (arch_decfloat_type): New prototype.
(arch_pointer_type): Likewise.
* gdbtypes.c (arch_decfloat_type): New function.
(arch_pointer_type): Likewise.
(gdbtypes_post_init): Use arch_decfloat_type.
* avr-tdep.c (avr_gdbarch_init): Use arch_pointer_type.
* ft32-tdep.c (ft32_gdbarch_init): Likewise.
* m32c-tdep.c (make_types): Likewise.
* rl78-tdep.c (rl78_gdbarch_init): Likewise.
