No "rflags" register in x86_64 architecture #1280

Closed vancaho closed 10 months ago

vancaho commented 10 months ago

Hi, when I call ctx->getRegister("rflags") it throws:

terminate called after throwing an instance of 'triton::exceptions::Cpu'
  what():  x8664Cpu::getRegister(): Invalid register for this architecture.

I read the documentation at https://triton-library.github.io/documentation/doxygen/py_REG_page.html, there is no rflags register for x86_64 architecture, and there are eflags registers for both x86 and x86_64 register.

Is there anything wrong? Should there be a rflags in x86_64?

it's the same thing. rflags has its 32msb reserved. In another words, only eflags is used in i386 or x86_64.
