It is able to handle 16-bit code as well, and comes with an own assembler and loader. (They are already known from Minix and Linux as the `bin86' package.) With a bit of `dd' magic, bcc can be used to compile messdos programs.

.Sh DESCRIPTION
|
|
|
|
.Ss Overview
|
|
|
|
.Nm Bcc
|
|
is a simple C compiler suitable for generating 8086 or 80386 code.
|
|
It basically understands the old K&R C input syntax, with some
|
|
restrictions on bit fields. It interacts with the programs
|
|
.Xr as86 1
|
|
and
|
|
.Xr ld86 1 .
|
|
|
|
As a compile-time option, it is also possible to convince
|
|
.Nm bcc
|
|
to generate code for the Motorola 6809 CPU.
|
|
|
|
