Change undef to poison in a few operations
...son:
- insertelement/extractelement (element index out of range)
- shufflevector (undef elements in shuffle mask)
- alloca (allocating zero bytes) ?
- load (load value with different type from written value)
- GEP inrange
- fptrunc/fptoui/fptosi/uitofp/sitofp (overflow) ?
- llvm.ctlz.* and friends (is_zero_undef) ?
Some of these are no brainers, others may need a bit of discussion.
Please let us know if you have thoughts and/or concerns about this.
Thanks,
Nuno
