[LLVMdev] Adding intrinsic with variable argument list HOWTO.
...een hitting my head to wall two days now. This is practically
my first contact with InstrInfo.td files. Is there any tutorial how to
make this kind of stuff? Or should I just keep on studying Sparc and
other backends?
So I added new intrinsic to llvm/include/llvm/TCEInstrinsics.td:
def int_tce_customop :
Intrinsic<[llvm_void_ty, llvm_ptr_ty, llvm_vararg_ty], [],
"llvm.tce.customop">;
I made opt pass that converts __custom_op() functions to calls to
llvm.tce.customop calls.
shell> grep llvm.tce.customop hello2.ll
tail call void (i8*, ...)* @llvm.tce.customop( i8...

[LLVMdev] Adding custom operation intrinsic for ASIP architectures.
...m operation intrinsic and optimization
pass for raising certain type of function calls to those intrinsics
(similar to raising mallocs).
Basically our custom operation are like calls, with operand name and
multiple inputs and outputs. e.g. C code:
__llvm__custom_op_add(a,b,c) would be raised to customop add(i32 %tmp1,
i32 %tmp24 , i32 %tmp25). Those "__llvm__custom_op_" prefixed function
will not have function body, but pure declarations in C code level.
Comments are welcome, especially if there anyone else, that needs this
kind of functionality or if people has already implemented s...

Let's study this more closely.

What is the mechanism to first insert the __llvm__custom_op IR operations? Are
these automatically decided by the code selec...
