...STUB_CODE, UM_KERN_PAGE_SIZE, PROT_EXEC, MAP_FIXED | MAP_PRIVATE, fd, offset); The previous code maps the page of code into memory: the page address is stored in the linker-script-defined __syscall_stub_start symbol. Then we have: unsigned long v = STUB_CODE + (unsigned long) stub_segv_handler - // a function stored in this page (unsigned long) &__syscall_stub_start; // from linker script set_sigstack((void *) STUB_DATA, UM_KERN_PAGE_SIZE); sigemptyset(&sa.sa_mask); sa.sa_flags = SA_ONSTACK | SA_NODEFER; sa.sa_handler = (void *) v; // Use this function.

Hello, The binaries produced by LLVM and other compilers divide code up into various sections, e.g. the .text section. What is the recommended approach to assigning a symbol the address of a section using LLVM? Using GCC/LD, you can do this with a linker script, e.g. in a linker script you can do: _text = .; _stext = .; These symbols are then available in the corresponding C code using an
