aarch64: use PTR_ARG and SIZE_ARG instead of DELOUSE
|
||
|
|
|
||
|
|
DELOUSE was added to asm code to make them compatible with non-LP64
|
||
|
|
ABIs, but it is an unfortunate name and the code was not compatible
|
||
|
|
with ABIs where pointer and size_t are different. Glibc currently
|
||
|
|
only supports the LP64 ABI so these macros are not really needed or
|
||
|
|
tested, but for now the name is changed to be more meaningful instead
|
||
|
|
of removing them completely.
|
||
|
|
|
||
|
|
Some DELOUSE macros were dropped: clone, strlen and strnlen used it
|
||
|
|
unnecessarily.
|
||
|
|
|
||
|
|
The out of tree ILP32 patches are currently not maintained and will
|
||
|
|
likely need a rework to rebase them on top of the time64 changes.
|
||
|
|
|
||
|
|
Keeping the DELOUSE macro avoids the need to update all string
|
||
|
|
functions. Lack of BTI markers and architecture variants cause many
|
||
|
|
conflicts in a full upstream backport.
