Syntax error asm volatile

[mmar]

I use some codes with
#define LDW(dst, mem, ind) asm("ldw %0, %1[%2]" : "=r"(dst) : "r"(mem), "r"(ind))
#define STW(src, mem, ind) asm("stw %0, %1[%2]" : "=r"(src) : "r"(mem), "r"(ind))

but optimizer removes it from code if =r is not used after macro usage.
I read assembler guide and use recommended volatile

#define STW(src, mem, ind) asm volatile("stw %0, %1[%2]" : "=r"(src) : "r"(mem), "r"(ind))

this is compiled but XDE shows SYNTAX ERROR in lines with macro.

How is functional 100% code for pointer type memory array read and write back?

For me only real C code works 100%. But in XC i need very frustrated calls to C code in other source file.

Missing semi-colon when calling the macro? Looks like valid syntax otherwise.

On screenshot is syntax error.
But no build error.
This error exist only when define have volatile clause.

#define LDW(dst, mem, ind) asm volatile("ldw %0, %1[%2]" : "=r"(dst) : "r"(mem), "r"(ind))

Ah, I thought you have a build error. Looks like an issue in the IDE.

Which version of the tool are you using? In 13.0.0 version of the tools, this issue is fixed. I presume you are using the older version of the tool.
