gcc support for C99 language extensions
- I'd like to further this along
Threads
- Hans Boehm's Threads and Memory Model for C++ page is awesome
Aliasing
- See Compiler Design page
- -O2 implies -fstrict-aliasing, at least as of gcc 4.3
- -Wstrict-aliasing=2 warns about many constructions unsafe to use with -fstrict-aliasing
- How to use Berkeley sockets API? See http://archives.free.net.ph/message/20080529.200047.b40321b6.fi.html, etc
stdint.h
An awesome addition. Type constructions of the form u?int{variety}_t (u prefix denotes unsigned). Varieties include:
- ptr: Size sufficient to hold a pointer. This is useful for function type definitions, when it's unsure whether a pointer or integer type would be most appropriate for various instances (a void *'s size is not directly related to an int's size by the ANSI C standard).
- max: Size sufficient to hold any other integer type.
- fast{8,16,32,64}: Fastest integer type having at least the specified width.
- least{8,16,32,64}: Minimum native integer type having at least the specified width.
- {8,16,32,64}: Integer type having precisely this width.
