i386 ABI

[Christoph Bartoschek <bartoschek@xxxxxx>]

Hi, 

reading the gcc manual about bit-fields I read that some things are ABI 
defined:

• The order of allocation of bit-fields within a unit (C90 6.5.2.1, C99 
6.7.2.1).
  Determined by ABI.


Now, where can I find the ABI for i386 Linux machines?
