…LowerZERO_EXTEND_AVX512/LowerSIGN_EXTEND_AVX512. NFCI Most of the code in these routines is for handling extends from vXi1 types. The 512-bit handling for other extends is very much like the AVX2 code. So make the special routines just do vXi1 types and move the other 512-bit handling to the place that handles AVX2. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@319878 91177308-0d34-0410-b5e6-96231b3b80d8
Current implementation of `compareSCEVComplexity` is being unreasonable with `SCEVUnknown`s: every time it sees one, it creates a new value cache and tries to prove equality of two values using it. This cache reallocates and gets lost from SCEV to SCEV. This patch changes this behavior: now we create one cache for all values and share it between SCEVs.

Csmith discovered a program that caused wrong code generation with -O0: When handling a SIGN_EXTEND in expandRxSBG(), RxSBG.BitSize may be less than the Input width (if a truncate was previously traversed), so maskMatters() should be called with a masked based on the width of the sign extend result instead.

Summary: If a partially inlined function has debug info, we have to add debug locations to the call instruction calling the outlined function. We use the debug location of the first instruction in the outlined function, as the introduced call transfers control to this statement and there is no other equivalent line in the source code. We also use the same debug location for the branch instruction added to jump from artificial entry block for the outlined function, which just jumps to the first actual basic block of the outlined function.
