-Module Name:\r
-\r
- GenDepex.c\r
-\r
-Abstract:\r
-\r
- Generate Dependency Expression ("GenDepex")\r
-\r
- Infix to Postfix Algorithm\r
-\r
- This code has been scrubbed to be free of having any EFI core tree dependencies.\r
- It should build in any environment that supports a standard C-library w/ string\r
- operations and File I/O services.\r
-\r
- As an example of usage, consider the following:\r
-\r
- The input user file could be something like "Sample.DXS" whose contents are\r
-\r
- #include "Tiano.h"\r
-\r
- DEPENDENCY_START\r
- NOT (DISK_IO_PROTOCOL AND SIMPLE_FILE_SYSTEM_PROTOCOL) \r
- OR EFI_PXE_BASE_CODE_PROTOCOL\r
- DEPENDENCY_END\r
-\r
- This file is then washed through the C-preprocessor, viz.,\r
-\r
- cl /EP Sample.DXS > Sample.TMP1\r
-\r
- This yields the following file "Sample.TMP1" whose contents are\r
-\r
- DEPENDENCY_START\r
- NOT ({ 0xce345171, 0xba0b, 0x11d2, 0x8e, 0x4f, 0x0, 0xa0, 0xc9, 0x69, 0x72,\r
- 0x3b } AND { 0x964e5b22, 0x6459, 0x11d2, 0x8e, 0x39, 0x0, 0xa0, 0xc9, 0x69,\r
- 0x72, 0x3b }) OR { 0x03c4e603, 0xac28, 0x11d3, 0x9a, 0x2d, 0x00, 0x90, 0x27,\r
- 0x3f, 0xc1, 0x4d }\r
- DEPENDENCY_END\r
-\r
- This file, in turn, will be fed into the utility, viz.,\r
-\r
- GenDepex Sample.TMP1 Sample.TMP2\r
-\r
- With a file that is 55 bytes long:\r
-\r
- 55 bytes for the grammar binary\r
- PUSH opcode - 1 byte\r
- GUID Instance - 16 bytes\r
- PUSH opcode - 1 byte\r
- GUID Instance - 16 bytes\r
- AND opcode - 1 byte\r
- NOT opcode - 1 byte\r
- PUSH opcode - 1 byte\r
- GUID Instance - 16 bytes\r
- OR opcode - 1 byte\r
- END opcode - 1 byte\r
-\r
- The file "Sample.TMP2" could be fed via a Section-builder utility \r
- (GenSection) that would be used for the creation of a dependency\r
- section file (.DPX) which in turn would be used by a generate FFS\r
- utility (GenFfsFile) to produce a DXE driver/core (.DXE) or \r
- a DXE application (.APP) file.\r
-\r
- Complies with Tiano C Coding Standards Document, version 0.31, 12 Dec 2000.\r

-\r
-Routine Description:\r
-\r
- This takes the pre-compiled dependency text file and \r
- converts it into a binary dependency file.\r
-\r
- The BNF for the dependency expression is as follows \r
- (from the DXE 1.0 Draft specification).\r
-\r
- The inputted BNF grammar is thus:\r
- <depex> ::= sor <dep> | \r
- before GUID <dep> | \r
- after GUID <dep> | \r
- <bool>\r
-\r
- <dep> ::= <bool> |\r
-\r
- <bool> ::= <bool> and <term> | \r
- <bool> or <term> | \r
- <term>\r
-\r
- <term> ::= not <factor> | \r
- <factor>\r
-\r
- <factor> ::= ( <bool> ) | \r
- <term> <term> | \r
- GUID | \r
- <boolval>\r
-\r
- <boolval> ::= true | \r
- false\r
-\r
- The outputted binary grammer is thus:\r
- <depex> ::= sor <dep> | \r
- before <depinst> <dep> | \r
- after <depinst> <dep> | \r
- <bool>\r
-\r
- <dep> ::= <bool> |\r
-\r
- <bool> ::= <bool> and <term> | \r
- <bool> or <term> | <term>\r
-\r
- <term> ::= not <factor> | \r
- <factor>\r
-\r
- <factor> ::= ( <bool> ) | \r
- <term> <term> | \r
- <boolval> | \r
- <depinst> | \r
- <termval>\r
-\r
- <boolval> ::= true | \r
- false\r
-\r
- <depinst> ::= push GUID\r
-\r
- <termval> ::= end\r
-\r
- BugBug: A correct grammer is parsed correctly. A file that violates the\r
- grammer may parse when it should generate an error. There is some\r
- error checking and it covers most of the case when it's an include\r
- of definition issue. An ill formed expresion may not be detected.\r
-\r
-Arguments:\r
-\r
- InFile - Input pre-compiled text file of the dependency expression.\r
- This needs to be in ASCII.\r
- The file pointer can not be NULL.\r
-\r
- OutFile - Binary dependency file.\r
- The file pointer can not be NULL.\r
-\r
- Padding - OPTIONAL integer value to pad the output file to.\r
-\r
-\r
-Returns:\r
-\r
- EFI_SUCCESS The function completed successfully.\r
- EFI_INVALID_PARAMETER One of the parameters in the text file was invalid.\r
- EFI_OUT_OF_RESOURCES Unable to allocate memory.\r
- EFI_ABORTED An misc error occurred.\r
