[PATCH] D87981: [X86] AMX programming model.

[Craig Topper via Phabricator via cfe-commits]

craig.topper added a comment.

This triggers an assertion in X86LowerAMXType::visit() when compiled with clang test.c -O3

  typedef int vec1024 __attribute__((vector_size(1024)));
  
  vec1024 foo(vec1024 x, vec1024 y) {
    return x + y;
  }



  While deleting: <256 x i32> %x 
  Use still stuck around after Def is destroyed:  %add = add <256 x i32> %y, %x
  clang-12: llvm/lib/IR/Value.cpp:100: llvm::Value::~Value(): Assertion `materialized_use_empty() && "Uses remain when a value is destroyed!"' failed.
