Hi H.J.
: I added support for the new DT tags from the new gABI. However, glibc
: 2.1 doesn't support them. I got
:
: BUG IN DYNAMIC LINKER ld.so: dynamic-link.h: 57: elf_get_dynamic_info: Assertion `! "bad dynamic tag"' failed!
:
: on DT_RUNPATH and DT_FLAGS when -Bsymbolic and -rpath are used. I
: checked Solaris 2.7. Solaris ld.so doesn't complain DT_RUNPATH nor
: DT_FLAGS which it doesn't know. I tend to think it is a glibc 2.1 bug.
: But I don't want to break glibc 2.1. I'd like to add a new option
: to ld to turn on the support for the new DT tags. Any suggestions?
: I am thinking of "-z gabi" for lack of imagination :-).
Do we need a switch, or can this be determined "magically" by
examining the input files ?
If we need a switch, then I would suggest:
--enable-dynamic-tags
and:
--no-enable-dynamic-tags
which presumably would be the default.
Cheers
Nick
