• crt0.o and crt1.o -- What's the difference?

  - by Earlz

  Hello, recently I've been trying to debug some low level work and I could not find the crt0.S for the compiler(avr-gcc) but I did find a crt1.S (and the same with the corresponding .o files) What is the difference between these two files? Is crt1 something completely different or what? They both seem to have to do with something for bootstrapping(setting up stack frame and such), but why the distinction?

• difference between where and nested queries

  - by Chris H

  I'm not able to figure out the difference between these queries. I'm pretty sure that the first one is an equi-join. I'm not sure how the second one ISN'T the same as the first. The sub query in #2 selects all Ids from S, and then it returns all R's that also have those ID's, no? SELECT R.cname FROM R, S, WHERE R.Id = S.Id SELECT R.cname FROM R WHERE R.Id IN (SELECT S.Id FROM S)

• Difference between macros and functions in C in relation to instruction memory and speed

  - by DAHANS

  To my understanding the difference between a macro and a function is, that a macro-call will be replaced by the instruction in the definition, and a function does the whole push, branch and pop -thing. Is this right, or have I understand something wrong? Additionally, if this is right, it would mean, that macros would take more space, but would be faster (because of the lack of the push,branch and pop instructions.), wouldn't it?
