[cfe-dev] error:instruction requires a CPU feature not currently enabled for pusha, popa, .code32, .code64,

[Santosh Nagarakatte]

While compiling bitvisor-1.1 with clang, I am getting the following
errors. I am using clang from the trunk 118916 with x86_64 on linux.

I have filed a new bug report 8595

http://llvm.org/bugs/show_bug.cgi?id=8595

callrealmode.c:62:3: error: instruction requires a CPU feature not currently
enabled
                "push %%rax\n"
                ^
