-; Hidden weak function with dso_local must still use GOT indirection
-; in PIC mode on ARM. The assembler eagerly resolves PC-relative
-; expressions like .long xxx-(.LPC+8) when both are in the same section,
-; which prevents the linker from overriding the weak definition with
-; a non-weak one from another object file.
+; Weak dso_local hidden functions must be overridable at link time
+; (a strong definition in another object should override the weak one).
