[cfe-dev] RFC: Implementing -fno-delete-null-pointer-checks in clang
...e it will avoid creating a new llvm optimization flag
and is auto embedded in IR.
Given that, how do we want to proceed, do we want to add yet another field
to the DataLayout string?
e.g.
1. Add to already overloaded pointer types? e.g.
p[n]:<size>:<abi>:<pref>:<idx>: *<NullPointerValid ? 1 : 0>*
2. (My preference) Or create another unique field identifier: e.g.
np[n]: <NullPointerValid
? 1 : 0>
Thanks,
Manoj

[cfe-dev] RFC: Implementing -fno-delete-null-pointer-checks in clang
I'm working with an embedded architecture that could, in some situations,
run faster if code or data could be located at address zero. I don't know
whether this applies to other embedded chips.
Despite the name, the flag actually has rather straightforward semantics
