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.
