oh, sorry I guess I've overlooked that detail :-)
Anyway, then make it:
static const char foo[] = {
0x01, 0x02, 0x03,
...
};
llvm/gcc puts const data in the .text segment (or a different read-only data
segment on some architectures), generating something like:
.section __TEXT,__const
.align 4 ## @foo
_foo:
...
