libgcc2.h (word_type): Type definition removed.
2007-07-06 Andreas Krebbel <krebbel1@de.ibm.com>
* libgcc2.h (word_type): Type definition removed.
(cmp_return_type, shift_count_type): Type definitions added.
(__lshrdi3, __ashldi3, __ashrdi3): word_type of second parameter
replaced with shift_count_type.
(__cmpdi2, __ucmpdi2): word_type of return type replaced with
cmp_return_type.
* libgcc2.c (__udivmoddi4, __moddi3): Type of local variable c
changed from word_type to Wtype.
(__lshrdi3, __ashldi3, __ashrdi3): word_type of second parameter
replaced with shift_count_type.
(__cmpdi2, __ucmpdi2): word_type of return type replaced with
cmp_return_type.
* c-common.c (handle_mode_attribute): Handling for libgcc_cmp_return and
libgcc_shift_count attribute added.
* target-def.h (TARGET_LIBGCC_CMP_RETURN_MODE,
TARGET_LIBGCC_SHIFT_COUNT_MODE): New target hooks defined.
(TARGET_INITIALIZER): New target hooks added.
* targhooks.c (default_libgcc_cmp_return_mode,
default_libgcc_shift_count_mode): Default implementations for the new
target hooks added.
* targhooks.h (default_libgcc_cmp_return_mode,
default_libgcc_shift_count_mode): Function prototypes added.
* target.h (struct gcc_target): Fields for the new target hooks added.
* optabs.c (expand_binop): Use shift_count_mode when expanding shift
as library call.
(prepare_cmp_insn): Use cmp_return_mode when expanding comparison as
library call.
* doc/tm.texi (TARGET_LIBGCC_CMP_RETURN_MODE,
TARGET_LIBGCC_SHIFT_COUNT_MODE): Documentation added.
* config/s390/s390.c (s390_libgcc_cmp_return_mode,
s390_libgcc_shift_count_mode): Functions added.
(TARGET_LIBGCC_CMP_RETURN_MODE, TARGET_LIBGCC_SHIFT_COUNT_MODE): Target
hooks defined.
