I guess you mean IA32 rather than IA33. Anyway, FPC is always compiled  
with support for creating code for one single cpu architecture. The  
currently supported ones are i386 (=IA32), x86_64, powerpc (32 bit),  
powerpc64, sparc and ARM. Apart from generating code for one such  
architecture, every such compiler can also only parse assembler code  
written for that same architecture (since there is no way the compiler  
can translate assembler code written for one architecture into  
assembler code for another architecture).

ARM support works fairly well (except for EABI support, which still  
has some bugs).
