[LLVMdev] Prevent a intrinsic to be reordered?
Nothing... I'll show you all the info related to:
The intrinsic: def int_soru_sre : Intrinsic<[llvm_void_ty, llvm_i32_ty],
[IntrWriteMem]>;
The lower instruction (in MIPS):
class SORUI<bits<6> op, dag outs, dag ins, string asmstr, list<dag> pattern,
InstrItinClass itin>: FI<op, outs, ins, asmstr, pattern, itin>
{
let isBarrier = 1; // o...

What is the description of the instruction you're lowering intrinsic
into? Have you looked for the instruction flags defined in Target.td
file? You instruction should definitely have "isBarrier" flag set.

[LLVMdev] Prevent a intrinsic to be reordered?
Hello, I have an intrinsic that matches to a asm instruction directly. This
intrinsic starts a coprocessor that can do anything.
If I put another instruction next to it (a multiplication for example), the
"llc" reorders and puts the intrinsic after the multiplication.
I have tried all:
- Setting the instruction like if it takes 256 cycles or 0 cycles.
- Setting the instruction with
