Description
Compiler Explorer: https://godbolt.org/z/4MzsKfT86
Both Clang Assertion Trunk and Clang Trunk crash at the following program:
__complex__ long long f () {
__complex__ long long v;
asm("": "+r" (v) : "r" (0), "r" (f ()));
return v;
}Stack dump:
clang: /root/llvm-project/clang/lib/CodeGen/CGValue.h:84: clang::CodeGen::Address clang::CodeGen::RValue::getAggregateAddress() const: Assertion `isAggregate() && "Not an aggregate!"' failed.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.
