400 | * A code fragment (frag) is some known number of chars, followed by some | |
401 | * unknown number of chars. Typically the unknown number of chars is an | |
402 | * instruction address whose size is yet unknown. We always know the greatest | |
403 | * possible size the unknown number of chars may become, and reserve that | |
404 | * much room at the end of the frag. | |
405 | * Once created, frags do not change address during assembly. | |
406 | * We chain the frags in (a) forward-linked list(s). The object-file address | |
407 | * of the 1st char of a frag is generally not known until after relax(). | |
408 | * Many things at assembly time describe an address by {object-file-address | |
409 | * of a particular frag}+offset. | |
