Matching assembler to C


Things to look for:

flow control... ifs, cases, whiles equate to tests, cmps and jumps
returns equate to big jumps to near the end of the functions
calling functions... pushing arguments onto the stack and making a call
constants, ors, locks all stand out (asm/spinlock.h)
use of pointers, arithmetic, memory manipulation

More than one way of doing things, compilers select different methods in different cases

It's a bit of an art, you get used to it....
