.i file with popa pusha .cod32 .code64 causing the problem

I am compiling bitvisor-1.1 with clang. While compiling the attached file
callrealmode.i, I am getting the following errors.

callrealmode.c:62:3: error: instruction requires a CPU feature not currently
enabled
                "push %%rax\n"
                ^
<inline asm>:30:1: note: instantiated into assembly here
pusha


callrealmode.c:62:3: error: warning: ignoring directive for now
                "push %%rax\n"
                ^
