Subject: M32R: Migrate from 'regset_from_core_section' to 'iterate_over_regset_sections'
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=5fac247f472389db46e7612d9e425991f77d64b7;p=binutils-gdb.git

M32R: Migrate from 'regset_from_core_section' to 'iterate_over_regset_sections'

For m32r GNU/Linux targets, don't define the gdbarch method
'regset_from_core_section', but the iterator method instead.

gdb/ChangeLog:

	* m32r-linux-tdep.c (M32R_LINUX_GREGS_SIZE): New macro.
	(m32r_linux_regset_from_core_section): Remove.
	(m32r_linux_iterate_over_regset_sections): New.
	(m32r_linux_init_abi): Adjust gdbarch initialization.
