Module Name:

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

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