Member Function Documentation

registerName() [1/3]

TCEString DisassemblyRegister::registerName ( const TCEString &  rfName, int  index, char  delim = '.'  )

static

Returns a name of the register.

Does the int -> string conversion itself, because Conversion::toString() uses stringstream which is slow.

Definition at line 77 of file DisassemblyRegister.cc.

                                                    {
    char buf[12];
    char *ptr = buf + sizeof(buf);
    *--ptr = 0; // last to terminating zero.
    // conversion from 2 to 10 base
    do {
        *--ptr = (index%10) + 48; // 48 is conversion to ascii.
        index /= 10;
    } while (index);
    *--ptr = delim;
    return rfName + ptr;
}

registerName() [2/3]

TCEString DisassemblyRegister::registerName ( const TTAMachine::RegisterFile &  rf, int  index, char  delim = '.'  )

static

Returns name of a register.

Definition at line 95 of file DisassemblyRegister.cc.

                                                             {
    return registerName(rf.name(), index, delim);
