Part Number: RM57L843

Hello,

The following statement does not compile: asm volatile ("\tsvc #0" : : "r" (1));

The compiler issue the error: ‘#18 expected a ")"’

Does version ti-cgt-arm_20.2.7 of the C/C++compiler accepts the GCC Inline Assembly full syntax?

__asm volatile (
AssemblerTemplate
: OutputOperands
[: InputOperands
[: Clobbers ]])

Thanks in advance for the response.
Marcio.

Hi Marcio,

The TI proprietary Arm compiler, often called armcl for short, will not support all the GCC accepted assembly instructions.

In my old threads we tried to copy a c variable into the register which will support in GCC compiler, but it is failed in armcl compiler.
