1) About Inline Assembly for x86 in Linux
http://www.ibm.com/developerworks/linux/library/l-ia.html?dwzone=linux

2) Syntax issues: Intel vs. AT&T
http://asm.sourceforge.net//articles/linasm.html

3) Links, articles, docs...

4) If you like see assembly generated by GCC use "--save-temps" option. 
In this case the assembly output will be different from first aproach by "humam" asm code, a lot of optimization and heavy use of stack, but it's interessing take a look.

#gcc --save-temps foo.c -o foo
#vi foo.s
