In standard C dialects, keyword auto uses the following syntax: register data-definition; The register type modifier tells the compiler to store the variable being declared in a CPU register (if possible), to optimize access. For example, register int i; Note that TIGCC will automatically store often used variables in CPU registers when the optimization is turned on, but the keyword register will force storing in registers even if the optimization is turned off. However, the request for storing data in registers may be denied, if the compiler concludes that there is not enough free registers for use at this place. ************************************************************************ While there are implementation differences, I would hardly say that the compiler is "free to ignore the register keyword". It might end up ignoring it, but it's definitely not the default behavior. However, this group is about PostgreSQL and this thread was devoted to some particular aspects missing in PostgreSQL, not to C language. Analogy with the C language is actually a bad analogy to consider when discussing databases, primarily because C language isn't a database. I don't think we should waste any more time discussing C language. -- http://mgogala.byethost5.com
