Hi, We are working on a new project which requires a retargetting a compiler to a small cpu on FPGA. The cpu is hand-coded and it supports only a limited number of instruction sets.
My questions are: 1. Since I have very limited experience with compilers (this is my first compiler project), is it wise to begin with gcc? I have googled-up smaller compilers like pcc, lcc and small-c and they seem like very good candidates. However, I would like to listen to the opinions of programmers who have worked with gcc or retargetted gcc. 2. How much is the effort in retargetting compilers? I heard it took months but it all depends on the level of experience of the programmer. So if an experienced programmer took 2 month, it might have taken a beginner 6 months or so. Thanks, HY
