Subject: H8: Set H8/300H as the default architecture for the H8 family.
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=ebf22fc26326ad138bea9dee536cf081e46dd6e1;p=thirdparty%2Fbinutils-gdb.git

H8: Set H8/300H as the default architecture for the H8 family.

H8/300H uses 32-bit addresses in its default advanced mode, whereas
H8/300 uses 16-bit addresses.  Updates affected test cases accordingly.

bfd/
	* cpu-h8300.c: Set H8/300H as the default architecture
	for the H8 family.
gas/
	* config/tc-h8300.c: Set H8/300H as the default architecture
	for the H8 family.
	* NEWS: Add info about the above change.
ld/
	* configure.tgt: Set H8/300H as the default architecture
	for the H8 family.
	* NEWS: Add info about the above change.
	* testsuite/ld-elf/elf.exp: Expect 32-bit addresses/pointers
	for H8 on __patchable_function_entries tests.
