[PATCH] D122836: [SimplifyLibCalls] Fold more memchr calls

[Dávid Bolvanský via Phabricator via llvm-commits]

xbolva00 added inline comments.


================
Comment at: llvm/test/Transforms/InstCombine/memchr-2.ll:108
 
 ; Fold memchr(a12345, 259, n) to n < 4 ? null : a12345 + 3
 ; to verify the constant 259 is converted to unsigned char (yielding 3).
----------------
But IR says N < 3

And gep is 2, not 3.

Confusing.
