For this we need to know the * distance in bytes from the start of the relocated record until * the end of the containing instruction. _This_ is what is stored * in the size part of the parameter, in this case. * * Also OUT_RESERVE denotes reservation of N bytes of BSS space, * and the contents of the "data" parameter is irrelevant. */ #include "nasm.h" #include "outlib.h" void nasm_do_legacy_output(const struct out_data *data) { … }
