Is there a reference to GCC and/or LLVM patches?
I just want to mention that in GCC s
is an arch-independent constraint: https://gcc.gnu.org/onlinedocs/gcc/Simple-Constraints.html#index-s-in-constraint
But since this won't ever change, it does not matter much.
clang support has been merged to trunk :)
"s" can be used to create an artificial reference for linker garbage collection, or define sections to hold symbol addresses. "S" does not work for a preemptible symbol in GCC while "s" does.
