Subject: Binary instruction operand type - Fast-math-flags - Vectorized IR
code
To: cfe-users@lists.llvm.org
Hello,
I'm using LLVM 3.4 and noticed that some of the IR binary instructions have
the following format:
<result> = frem [fast-math flags]* <ty> <op1>, <op2> ; yields
ty:result
I'm mainly interested in extracting the type of the operands, regardless of
whether the fast-math-flags are set or not.
In the case above, that would be floating-point or vector.
Q1. I was just wondering if doing I.getOperand(0)->getType() would be
sufficient to extract the operands type.
I've tried it and I get a TokenTyID for a float operand.
Q2. Moreover, how can one extract the fast-math-flags?
Q3. I'd also appreciate it if someone could tell me what C/C++ source
code should I use to generate IR code that
includes some binary operation(s) with vector operands.
Many thanks,
Simona
