Can I compile an assembly file(.s file) with .c files in codewarrior10.6?

weiranhe — Thu, 21 Aug 2014 07:20:35 GMT

Hi! I'm using CW10.6 for MPC5646B, now I need to add an assembly file(.s file) to my project, can I compile it with other .c files? I try it, but it makes a lot of errors.

Can anybody help me? There is an function in the assembly file, I need to call it in another .c file.

I tried with CodeWarrior v10.6, and also have problem with the assembly file compiling. I have contacted compiler team for the solution.

Now, you can use embedded assembly code in C file to work it around, just like below:

__declspec(section ".init") __asm void cfg_WATCHDOG(void);

__asm void cfg_WATCHDOG(void)

{

nofralloc

/* Clear the soft lock bit SWT_CR.SLKSWT_CR: */

/* SR --> 0x0000c520 */

lis r4, 0

ori r4, r4, SR_WSC_1@l

lis r3, SWT_SR@ha

stw r4, SWT_SR@l(r3)

/* SR --> 0x0000d928 */

lis r4, 0

ori r4, r4, SR_WSC_2@l

stw r4, SWT_SR@l(r3)

/* Disable watchdog, SWT.CR.WEN = 0*/

lis r4, CR_VALUE@h

ori r4, r4, CR_VALUE@l

lis r3, SWT_CR@ha

stw r4, SWT_CR@l(r3)

blr

}

I will get back to this issue as soon as I have the solution for assembly files compiling in CW10.6.

Sorry for the waiting.

The reported errors are due to project is created for VLE instructions and assembly file (.s) added has a BOOKE instructions.

By adding the option -ppc_asm_to_vle in (Project Properties->C/C++ Build->Settings->Tools Seetings -> PowerPC Assembler -> General -> Other Flags), the below reported error should be resolved. (convert UISA/BOOKE instructions to VLE)

Best Regards

In KDS2.0 how can i compile .S file with .c file. I couldn't find 'PowerPC Assembler' in Project Properties->C/C++ Build->Settings->Tools Seetings -> PowerPC Assembler

Thanks!
