Philip Reames 72d2352801 [AlignFromAssume] Bailout w/non-constant alignments (pr51680) 
This is a bailout for pr51680.  This pass appears to assume that the alignment operand to an align tag on an assume bundle is constant.  This doesn't appear to be required anywhere, and clang happily generates non-constant alignments for cases such as this case taken from the bug report:

// clang -cc1 -triple powerpc64-- -S -O1 opal_pci-min.c
extern int a[];
long *b;
long c;
void *d(long, int *, int, long, long, long) __attribute__((__alloc_align__(6)));
void e() {
  b = d(c, a, 0, 0, 5, c);
  b[0] = 0;
}

This was exposed by a SCEV change which allowed a non-constant alignment to reach further into the pass' code.  We could generalize the pass, but for now, let's fix the crash.

GlobalOpt This patch extends the OptimizeGlobalAddressOfMalloc to handle the null check of global pointer variables. It is disabled with https://reviews.llvm.org/rGb7cd291c1542aee12c9e9fde6c411314a163a8ea. This PR is to reenable it while fixing the original problem reported. The fix is to set the store value correctly when creating store for the new created global init bool symbol. 2021-07-20 12:27:26 -04:00
