# PR 16044 is about a (compile-time-non-local) hidden function symbol,
|
||
|
|
# entered as an undef reference with a R_CRIS_32_PLT_GOTREL relocation
|
||
|
|
# referring to a hidden symbol, later defined. Here, we invalidly
|
||
|
|
# incremented the h->plt.refcount (from -1) as part of that relocation
|
||
|
|
# processing. There are some PLTGOT relocations. As there are no
|
||
|
|
# circumstances requiring a PLT entry for this symbol, its PLT entry
|
||
|
|
# can be eliminated and the PLTGOT relocations can be made to a static
|
||
|
|
# element in the GOT, relocated with the absolute-to-relative
|
||
|
|
# R_CRIS_RELATIVE relocation without symbol lookup. As part of
|
||
|
|
# eliminating unneeded PLT entries (and PLTGOT to "static" GOT
|
||
|
|
# elimination), a later pass noticed the inconsistency through an
|
||
|
|
# assert.
|
||
|
|
#
|
||
|
|
# The key points in this dump that may need future adjustments are the
|
||
|
|
# single dynamic relocation, that the dsofn symbol it points to, is
|
||
|
|
# local, its absence from the dynamic symbol table and that the
|
||
|
|
# relocation and symbol values match.
