[edk2-devel] [PATCH v2 1/1] BaseTools: Build ASL files before C files

Pierre:
I see you use ':' to describe the dependency between the different source file. This is makefile syntax for the dependency. If one file depends on more than one files, other files will list after this file with the separator space ' '. So, I think the example should be like below.
> [Sources]
> FileName1.X
> FileName2.Y : FileName1.X
> FileName3.Z : FileName1.X FileName3.Y
Thanks

> The dependencies for C files are satisfied by the build system.
> However, there are use cases where source files with different languages are inter-dependent. The EDKII build framework currently
> doesn't have options to specify such dependencies.
> E.g. It may be necessary to specify the build order between
> ASL files and C files. The use case being that the AML
> blob generated by compiling the ASL files is loaded and
> parsed by some C code.
>
> This patch allows to describe dependencies between files listed in the '[Sources]' section of '.inf' files. The list of source files to build
> prior are colon separated (':'), e.g.:
> [Sources]
> FileName1.X
> FileName2.Y : FileName1.X
> FileName3.Z : FileName1.X : FileName3.Z
>
> In the example above:
> * FileName1.X will be built prior to FileName2.Y.
> * FileName1.X and FileName2.Y will be built prior to
> FileName3.Z.
>
> This does not affect the file specific build options, which are pipe separated, e.g.:
> FileName2.Y | GCC : FileName1.X
>
> The list of colon separated files must be part of the module, i.e. they must be present in the [Sources] section.
>
> Their file extension must be described in the BaseTools/Conf/build_rule.template file, and generate an output file, i.e. have a non-
> empty '<OutputFile>' section.
>
> Declaring a dependency in the [Sources] sections leads to the creation of makefile rules between these files in the build. The makefile
> rule is between the generated files.
> E.g.:
> FileName1.X generates FileName1.objx
> FileName2.Y generates FileName2.objy
> Then
> FileName2.Y : FileName1.X
> will create the following makefile rule:
> FileName2.objy : FileName1.objx
>
> INF Specification updates:
> s3.2.1, "Common Definitions":
> <SrcDependencySeperator> ::= ":"
> <DepS> ::= <TS> <SrcDependencySeperator> <TS>
>
> s2.5, "[Sources] Section":
> To describe a build order dependency between source
> files, specify the source files to build prior by
> listing them, colon separated.
> <opt3> ::= <FS> [<FeatureFlagExpress>] [<opt4>]*
> <opt4> ::= <DepS> [FileNameDependency]
