Ok so you did the statics with undefined size, so kind of an extern static.
That's a weird construct (not sure if it's even allowed in standard C), but
somehow it seems to work in gcc with the inline assembler.
I checked the code general and with the .globl in NATIVE_LABEL the
generated assembler looks like it should work even for LTO yes.
I guess it's an interesting alternative to making them all global.
Maybe that will work for more cases too.
Thanks.
