hi, I wonder if it is possible to know which register the compiler is going to use to generate PIC code on ia32. i.e., most of the references I found mention only ebx but the only ia32 system I have access to (Xeon E5410) which is running FC10 and gcc 4.3.2 compiles a sample foo function accessing a global variable with the ecx register. Is there any ABI rule about which register is supposed to be used ? If the compiler free to use any register ? Does it really use _any_ register in practice ?
