I have an 8086 CPU emulator. It emulates only 8086 instructions. I am searching now for a C compiler to target this emulator with. Is there any C compiler out there that can do this?
Also, having a usable libc and such is not important to me. The emulator uses custom(ie, non-PC) hardware and therefor any libc or even ctr0 would probably have to be rewritten anyway

The compiler that we recommend is the GNU Compiler collection or GCC. This is a widely used cross-platform compiler toolsuite that has libraries and compilers for C, C++, Fortran, Java, and more. Additionally the compiler that we will use later on in the course for compiling C code to run on the PIC32 is based on GCC.
Software Engineering C There are over 50 compilers for C like ICC by Intel to GNU GCC by GNU Project.
Accessing C Code from Within C++ SourceAll C++ compilers also support C linkage, for some compatible C compiler. When you need to access a function compiled with C linkage (for example, a function compiled by the C compiler, or a function written in assembler), declare the function to have C linkage.
Yes, C programs are first compiled to generate the object code and then that object code is Run.
bcc - Bruce's C compiler
From bcc(1) - Linux man page:
Description
Bcc is a simple C compiler that produces 8086 assembler, in addition compiler compile time options allow 80386 or 6809 versions. The compiler understands traditional K&R C with just the restriction that bit fields are mapped to one of the other integer types.
The default operation is to produce an 8086 executable called a.out from the source file.
Open Watcom
From the description of compiler option / 80x86 run-time convention 0 in Open Watcom C/C++ User’s Guide (PDF link):
(16-bit only) The compiler will make use of only 8086 instructions in the generated object code. This is the default. The resulting code will run on 8086 and all upward compatible processors. The macro __SW_0 will be predefined if "0" is selected
