15 | \r | |
16 | Abstract:\r | |
17 | \r | |
18 | Processor or Compiler specific defines and types for IA-32.\r | |
19 | We are using the ANSI C 2000 _t type definitions for basic types.\r | |
20 | This it technically a violation of the coding standard, but they\r | |
21 | are used to make EfiTypes.h portable. Code other than EfiTypes.h\r | |
22 | should never use any ANSI C 2000 _t integer types.\r | |
