19199767f8SToomas Soome 
20199767f8SToomas Soome   Processor or Compiler specific defines and types for IA-32.
21199767f8SToomas Soome   We are using the ANSI C 2000 _t type definitions for basic types.
22199767f8SToomas Soome   This it technically a violation of the coding standard, but they
23199767f8SToomas Soome   are used to make EfiTypes.h portable. Code other than EfiTypes.h
24199767f8SToomas Soome   should never use any ANSI C 2000 _t integer types.
