Question regarding X86::getCondFromBranch()
...X86::getCondFromBranch(const MachineInstr &MI) {
switch (MI.getOpcode()) {
default: return X86::COND_INVALID;
case X86::JCC_1:
return static_cast<X86::CondCode>(
MI.getOperand(MI.getDesc().getNumOperands() - 1).getImm());
}
}
returns an invalid condition for JCC_2 and JCC_4 conditional opcodes.
What is the suggested way to figure out the condition code for JCC_2 and JCC_4?
Should I just roll one up for myself to handle such opcodes based on
the above? Am I missing something conceptually?
Thanks,

A Propeller link (similar to a Thin Link as used by ThinLTO)?
I met with the Propeller team today (we work for the same company but it
was my first time meeting two members on the team:) ).
One thing I have been reassured:
* There is no general disassembly work. General
disassembly work would assuredly frighten off developers. (Inherently
unreliable, memory usage heavy and difficult to deal with CFI, debug
information, etc)
Minimal amount of plumbing work
