How to force Clang to put a variable at specific absolute address?

octal · March 22, 2013, 4:15pm

(PS. I don't want solution purely based on linker scripts)

On some Gcc versions, we use __attribute__((address(0xnnnn))) tu put a variable at adress 0xnnnn
On Clang I have seen something like "address_space" but it doesn't seem to do anything on MIPS port of LLVM.
Is this the correct attribute to use, or do I have to implement a new attribute?

Regards

We don't currently support any attributes for doing this.
Address spaces are a different concept.

We don't currently support any attributes for doing this.

This can be (in hackish way) emulated via changing global name to
address via asm()
