[PATCH] aarch64: Avoid hidden symbols for memcpy/memmove into static binaries
- From: Siddhesh Poyarekar <siddhesh at sourceware dot org>

- Subject: [PATCH] aarch64: Avoid hidden symbols for memcpy/memmove into static binaries
- Authentication-results: sourceware.org; auth=none
The __GI_* symbol aliases for __memcpy_generic are unnecessary since
they're never used. Add them only for libc.so to avoid PLT.
* sysdeps/aarch64/multiarch/memcpy_generic.S (__GI_memcpy):
Define only for libc.so.
