This patch series is in support of the glibc RTLD_SHARED work
discussed in https://sourceware.org/bugzilla/show_bug.cgi?id=22745.
This patch series adds changelog entries to the previous version.
It adds a DT_GNU_FLAGS_1 dynamic section and a DF_GNU_1_UNIQUE flag
which is intended to mark libraries which should implicitly be opened
as if RTLD_SHARED had been passed to dlmopen when the target namespace
is not LM_ID_BASE.
This patch series adds support for -z unique to ld, gold, and
readelf (and documents it in the help text and so forth).
It replaces previous patch series which (respectively):
- added a DT_FLAGS_1 value (that flag space has been exhausted)
- added a DT_GNU_UNIQUE section (whose contents were ignored)
Vivek Das Mohapatra (6):
Define a new DT_GNU_FLAGS_1 dynamic section for ld, readelf et al
Handle -z unique/-z nounique in ld
Document -z unique/-z nounique in the ld man page and help output
Handle DT_GNU_FLAGS_1 in readelf
Define DT_GNU_FLAGS_1 and DF_GNU_1_UNIQUE for gold
Implement and document -z unique / -z nounique handling in gold
