Given the above I think we need it sooner rather than later. Who's got the power to make it happen?


Would switching from .init to DT_INIT_ARRAY be an incompatible ABI change? I think I remember the GNU linker can handle mixing both types of sections in one executable but I am not sure if that is right.

I added Richard Sandiford to this email in case he hasn't seen it on the
libc mailing lists.

Both gcc and ld have an --enable-initfini-array configuration switch.

Both programs can autodetect the current host setting during native builds to preserve the system setting.

I don't believe there's currently a way to force the setting on based on a configuration triple, but it ought not be hard to add.
