I am trying to compile BIOS V6 as from CCSV4 with a bare-metal arm-gcc toolchain (4.4.1) and binutils (2.19).

[snip]

For about six assembly files, there is a *specific* include that is needed.
For example the file Cache_asm.s needs to include package/internal/Cache.xdc.h
Whereas the file HwiCommon_asm.s needs to incldue package/internal/HwiCommon.xdc.h.

In other words, for each of these five assembly files, I need to run gcc with a specific '-imacros <filename>'.
I'm imagining there may be a way to set a target specific 'copts' attribute
- and in fact there are examples of how to do this in the RTSC help in the
Library.addObjects() function.
BUT there are a couple catches.
First catch - is I need to do this only for targets where I've changed the
extension from .s470 (TI 470 assembler) to .sBMArmR4 (gcc bare-metal ARM R4 target). Right now I've followed other examples in the BIOS tree and only used the
file basename in the 'objects' list. The local gcc bare-metal ARM R4 target
matches files with extension .sBMArmR4 and only *those* files are the ones
I need to add the -imacro header.h file name to.

Second catch, the build environment for BIOS includes a common build script
that adds all the objects in object list to the library.
So it will already have been added to the library with Library.addObject()
and *after the fact* I'd need to add a specific header file to the gcc command line for each of the individual assembly files.

I'm looking for some suggestions on how this might be accomplished; or maybe
an idea on a different way to tackle the issue.

But, again, the BIOS team might have a better answer for their build setup.

BIOS has a few assembly language files that include "C" header files with a
line in the assembly source containing a directive ".CDECLS ... header.h"

That much is ok.  I've tried this from the command line and it works fine.

My problem now is to get the same effect through the XDC build script.

Is there a way to find out the size of the structure (declared in xdc file) in module's xs file.
for example i have a structure
like below in xdc file

module xdc file

struct entry
{
    UInt32 a;
    uinon {
       UInt8 b;
       UInt32 c;
    }
};

In xs file i have to  know the size of <mod>_entry structure size.

How do i do this. Please let me know if any body knows  how to do it?.

Is it allowed to call  some thing like below in module's xs file.

GateSwi.Handle handle;
handle = GateSwi.create();
handle = GateSwi.Handle_upCast(handle);

module xdc file

struct entry
{
    UInt32 a;
    uinon {
       UInt8 b;
       UInt32 c;
    }
};

In xs file i have to  know the size of <mod>_entry structure size.

Mod.xdc:
    module Mod {
        config Int ARR_SIZE = 2;
    instance:
        config Int myArr[ARR_SIZE] = [0, 0];
    }

User's .cfg script:
    var Mod = xdc.useModule("...Mod");
    Mod.ARR_SIZE = 10;

User's .c code:
    main() {
        Mod_Params params;
        Mod_Handle inst;

        Mod_Params_init(&params);
        for (i = 0; i < Mod_ARR_SIZE; i++) {
            params.myArr[i] = i;  /* ERROR: myArr has just 2 elements */
        }
        inst = Mod_create(&params, NULL);
    }

User's .c code:
    Int myArr[10] = [1, ...];

    main() {
        Mod_Params params;
        Mod_Handle inst;

        Mod_Params_init(&params);
        inst = Mod_create(&params, NULL);
        Mod_initArray(inst, myArr, sizeof(arr));
    }

dave,

For example   i have the following  configuration in  xdc file

config  UInt32 ARR_SIZE = 2;

instance:

config UInt32 myArr[ARR_SIZE ]= [0,0] /* here normal procedure is to initialize all the 2 elements. Suppose if ARR_SIZE is changed to a higher value through the cfg file static initialization of myArr gives error. To avoid this static initialization of myArr needs to be done some how either in xs file or some other place.

why we need this type of declaration is application users does not like to have pointers to which they have to declare variables and assign them to pointers in Params.

my requirement is such that dimension of the array needs to be set thorough the cfg file. And in xdc/xs file array elements should be initialized.
