There was a problem hiding this comment.
Please rename the file to array-init.cpp, or if the expected output is the same between C and C++, then might be better just to append this to existing clang/test/CIR/CodeGen/array-init.c instead.

Mistakenly closed #850 #850 (review) This PR fixes array initialization for expression arguments. Consider the following code snippet `test.c`: ``` typedef struct { int a; int b[2]; } A; int bar() { return 42; } void foo() { A a = {bar(), {}}; } ``` When ran with `bin/clang test.c -Xclang -fclangir -Xclang -emit-cir -S -o -`, It produces the following error: ``` ~/clangir/clang/lib/CIR/CodeGen/CIRGenExprAgg.cpp:483: void {anonymous}::AggExprEmitter::buildArrayInit(cir::Address, mlir::cir::ArrayType, clang::QualType, clang::Expr*, llvm::ArrayRef<clang::Expr*>, clang::Expr*): Assertion `NumInitElements != 0' failed. ``` The error can be traced back to `CIRGenExprAgg.cpp`, and the fix is simple. It is possible to have an empty array initialization as an expression argument!
