I'm running up against an error with this IR: %array$str = type { i64, [0 x %str] } %array.raw = call i8* @malloc(i64 %objsz) %array = bitcast i8* %array.raw to %array$str* %array.data = getelementptr %array$str* %array, i32 0, i32 1 This is kind of hand-written, but it errors out, like this: print-var.ll:50:30: error: invalid getelementptr indices %array.data = getelementptr %array$str* %array, i32 0, i32 1...

...d (presumably because LLVM doesn't know its alignment requirements so can't lay out the array$str type properly). For example, the following complete program works correctly for me: %str = type {i8*, i64} %array$str = type { i64, [0 x %str] } declare i8* @malloc(i64) define i64 @foo(i64 %objsz) { %array.raw = call i8* @malloc(i64 %objsz) %array = bitcast i8* %array.raw to %array$str* %array.data = getelementptr %array$str* %array, i32 0, i32 1 %ret = ptrtoint [0 x %str]* %array.data to i64 ret i64 %ret } But it fails if the first line is commented out. Could you give a similar...
