Does this idiom work if the inline asm block is duplicated by the compiler (e.g. due to inlining, loop unrolling, etc)?This is an idiom that shows up several places in glibc and in the kernel. In glibc, Jakub currently goes to heroic efforts to generate the unwind information by hand, but this code is what you might call write-only i.e. intensely difficult to modify.
Yes.
