There have been a couple postings recently regarding relocation warnings that have been observed when using the link-editors -z verbose option. The first warning originates from building a shared object:
ld: warning: relocation warning: R_SPARC_DISP32: file shared.o: \
symbol <unknown>: displacement relocation applied to the \
symbol __RTTI__1nEBase_: at 0x8: displacement relocation will \
not be visible in output image
Then, if this shared object is referenced as a dependency when building a dynamic executable, another warning can be generated:
ld: warning: relocation warning: R_SPARC_COPY: file shared.so: \
symbol xxxx: may contain displacement relocation
These warnings stem from an old request from the compiler folks to help prevent problems with displacement relocations and copy relocations.
You have to be a little relocation savvy to understand these scenarios — they make my head hurt. Investigations are underway to determine why these warnings are starting to surface.
