Code other than EfiTypes.h 22 should never use any ANSI C 2000 _t integer types. 23 24 --*/ 25 26 #ifndef _EFI_BIND_H_ 27 #define _EFI_BIND_H_ 28 29 30 #define EFI_DRIVER_ENTRY_POINT(InitFunction) 31 32 #define EFI_APPLICATION_ENTRY_POINT EFI_DRIVER_ENTRY_POINT 33 34 #define ECP_CPU_IPF 35 36 37 // 38 // Make sure we are useing the correct packing rules per EFI specification 39 // 40 #pragma pack() 41 42 43 #if _MSC_EXTENSIONS 44 45 #if __INTEL_COMPILER 46 47 // 48 // Disable the extra ";" warning; 49 // All places referencing EFI_GUID_STRING MACRO will generate this error. 50 // 51 #pragma warning ( disable : 424 ) 52 53 // 54 // error #593: variable "Status" was set but never used 55 // This error may be flagged if a function only do ASSERT on return status when 56 // EFI_DEBUG is not defined (EDK's ASSERT will be defined as empty statement). 57 // To make EdkCompatibilityPkg buildable by ICC with EFI_DEBUG undefined, disable 58 // this warning. 59 // 60 #pragma warning ( disable : 593 ) 61 62 // 63 // Disable ICC's remark #869: "Parameter" was never referenced warning. 64 // This is legal ANSI C code so we disable the remark that is turned on with -Wall 65 // 66 #pragma warning ( disable : 869 ) 67 68 // 69 // Disable ICC's remark #1418: external function definition with no prior declaration. 70 // This is legal ANSI C code so we disable the remark that is turned on with /W4 71 // 72 #pragma warning ( disable : 1418 ) 73 74 // 75 // Disable ICC's remark #1419: external declaration in primary source file 76 // This is legal ANSI C code so we disable the remark that is turned on with /W4 77 // 78 #pragma warning ( disable : 1419 ) 79 80 // 81 // Disable ICC's remark #869: "Parameter" was never referenced warning. 82 // This is legal ANSI C code so we disable the remark that is turned on with -Wall 83 // 84 #pragma warning ( disable : 869 ) 85 86 #endif 87 88 89 90 // 91 // Disable warning that make it impossible to compile at /W4 92 // This only works for Microsoft tools.
