Structures

1)Why in assembler code I can't do this:

C Header file:

typedef struct tag_SomeBitfield

{

unsigned int bf:1;

} SomeBitfield;

C file:

...

SomeBitfield bfObj;

asm

{

bfset bfObj.bf

}

I should do this:

asm

{

bfset #$1,bfObj

}

2) Initialisation of structures

Why I can't initialise structure immideatly. Is will be so useful, when I have only one object.

struct OneObject

{

int a=0;

int b:1=1;

.....

}

struct OneObject Object1 - Default initialisation already defined!;

Stupid way:

struct Name

{

....

...

} Object=

{

...

Big Object! Screen is not latex!

...

}

struct a

{

int x;

int y;

...

}

#define init\

2,\

4,\

...

struct a b={init};

...

Hello

I assume you are using a HC08 MCU. AM I right?

1- Inline Assembler does not support "bfset bfObj.bf"
     That is right. This notation is not supported by the inline assembler.
     You actually have to write it as "bfset #$1,bfObj".
      I will submit that as a possible improvement in the compiler.

2- Initializing a structure
The CodeWarrior compiler supports the standard ANSI C notation to initialize a structure. ANSI C standard specifies that a structure must be initialized as follows:

struct Name

{

....

...

} Object=

{

...

}

This is not something we can change.
