# Check dissassembly of the .plt section, specifically the synthetic
|
||
|
|
# symbols, in a DSO in which a .got.plt entry has been merged into a
|
||
|
|
# regular .got entry. There was a bug in which some (i.e. subsequent
|
||
|
|
# with regards to reloc order) synthetic X@plt entries were wrong if
|
||
|
|
# there were merged .got entries present; dsofn4@plt below. The
|
||
|
|
# alternatives in the matching regexps are placeholders for a future
|
||
|
|
# improvement: synthetic symbols for .plt entries with merged .got
|
||
|
|
# entries (lost as a consequence of the relocs no longer accounted for
|
||
|
|
# in .rela.plt and the default synthetic-symbol implementation just
|
||
|
|
# iterating over .rela.plt).
