These two failed for me also. The resulting llvm IR (for "Struct"):
; ModuleID =
'/home/asl/proj/llvm/src/test/CFrontend/2007-04-11-InlineAsmStruct.c'
target datalayout =
"e-p:32:32:32-i1:8:8-i8:8:8-i16:16:16-i32:32:32-i64:32:64-f32:32:32-f64:32:64-v64:64:64-v128:128:128-a0:0:64"
target triple = "i686-pc-linux-gnu"
%struct.V = type { i16, i16 }
define i32 @bar() {
entry:
%retval = alloca i32, align 4 ; <i32*> [#uses=2]
%tmp = alloca i32, align 4 ; <i32*> [#uses=2]
%bar = alloca %struct.V, align 4 ; <%struct.V*>
[#uses=2]
"alloca point" = bitcast i32 0 to i32 ; <i32>
[#uses=0]
call void asm sideeffect "foo $0\0A",
"=*r,~{dirflag},~{fpsr},~{flags}"( %struct.V* %bar )
%tmp1 = getelementptr %struct.V* %bar, i32 0, i32
0 ; <i16*> [#uses=1]
%tmp2 = load i16* %tmp1 ; <i16> [#uses=1]
%tmp23 = sext i16 %tmp2 to i32 ; <i32> [#uses=1]
store i32 %tmp23, i32* %tmp
%tmp4 = load i32* %tmp ; <i32> [#uses=1]
store i32 %tmp4, i32* %retval
br label %return
return: ; preds = %entry
%retval5 = load i32* %retval ; <i32> [#uses=1]
ret i32 %retval5
}
It seems, extra GEP was used to get result.
