XRT works with precompiled binaries which are compiled by Xilinx SDx compiler 
called xocc. The binary (xclbin) is loaded by clCreateProgramWithBinary().

Although the compiler is not open source the compilation flow lets users examine
output from various stages. For example if you write your kernel in OpenCL/C/C++ 
you can view the RTL (Verilog/VHDL) output produced by first stage of compilation. 
Note that the compiler is really generating a custom circuit given a high level 
input which in the last phase gets synthesized into bitstream. Expert hardware 
designers can handcraft a circuit in RTL and feed it to the compiler. Our FPGA tools 
let you view the generated hardware design, the register map, etc. You can get more 
information about a compiled design by running XRT tool like xclbinutil on the 
generated file.

In essence compiling for FPGAs is quite different than compiling for GPU/CPU/DSP.
Interestingly FPGA compilers can run anywhere from 30 mins to a few hours to 
compile a testcase.
