Assembler labels

Assembly labels specify the assembly code name to use for a C symbol.

For example, you might have assembly code and C code that uses the same symbol name, such as counter. Therefore, you can export a different name to be used by the assembler:

int counter __asm__("counter_v1") = 0;

This exports the symbol counter_v1 and not the symbol counter.
