[LLVMdev] Memset/memcpy: user control of loop-idiom recognizer
Hi,
In feedback from game studios a common issue is the replacement of
loops with calls to memcpy/memset. These loops are often
hand-optimised, and highly-efficient and the developers strongly want
a way to control the compiler (i.e. leave my loop alone).
The culprit is of course the loop-idiom recognizer. This replaces any
loop that looks like a memset/memcpy with calls. This affects loops
