; This test checks that the translator doesn't crash if the module has literal
; structs, i.e. structs whose type has no name. Typicaly clang generate such
; structs if the kernel contains OpenCL 2.0 blocks. The IR was produced with
; the following command:
; clang -cc1 -triple spir -cl-std=cl2.0 -O0 literal-struct.cl -emit-llvm -o test/literal-struct.ll
; literal-struct.cl:
; void foo()
; {
; void (^myBlock)(void) = ^{};
; myBlock();
; }
