<br>
I have a problem with clang and the address space attribute. I don't know if it is intended or a bug. The following code compiles fine as a .c file but fails as .cpp:<br>
<br>
C-Code:<br>
int __attribute__((address_space(1))) globalint = 10;<br>
<br>
bitcode:<br>
@globalint = addrspace(1) global i32 10, align 4 ; <i32 addrspace(1)*> [#uses=0]<br>
<br>
Error in clangtest.cpp:<br>
clangtest.cpp:2:39: error: cannot initialize a variable of type 'int<br>
__attribute__((address_space(1)))' with an rvalue of type 'int'<br>
int __attribute__((address_space(1))) globalint = 10;<br>
^ ~~<br>

I have additional problems with classes. In which cases are none zero address spaces supported, is there a documentation around?<br></font></p></div></blockquote><div>Not much.
