|
||||
However, the ACK's linker doesn't know
|
||||
how to emit word addresses into the program's data sections, and so a

separate fixup stage has to happen at runtime, just before \fBmain()\fP,

to convert the byte addresses into word addresses.

|

The end result is that using multiple source files with B is somewhat
|

unwieldy, requiring each module to be explicitly named and then an extra
|

stage to generate the fixup code. See the \fBack\fP(1) and \fBabmodules\fP(1)
