[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [PATCH v7 07/11] Arm32: use new-style entry annotations for library code
No functional change, albeit all globals now become hidden, and aliasing
symbols (__aeabi_{u,}idiv) as well as __memzero lose their function-ness
and size.
Signed-off-by: Jan Beulich <jbeulich@xxxxxxxx>
---
If the function-ness is important, some new construct would need
inventing. Not setting size for the aliases may even be desirable, as
I'm uncertain whether it is really legal in ELF that two entities
overlap in space.
I fear I'm breaking __memzero(), as I don't understand the purpose of
the ".word 0" next to where the FUNC_LOCAL() appears.

v7: New.
