[LLVMdev] set of integers to metadata
Hello everyone,
I want to pass a set of integers using metadata but I don't know how. I
have tried:
the integers are in array[]
*1. *
LLVMContext& C = is->getContext();
Value* values[size];
for(int gy=0;gy<size;gy++){
values[gy]=ConstantInt::getSigned(Type::getInt64Ty(C),array[gy]);
}
*is->setMetadata("path",MDNode::get(C,values));*
failes when setMetadata(), since
*Hello.cpp:706:56: error: no matching function for call to
‘llvm::MDNode::get(llvm::LLVMContext&, llvm::Value* [(((unsigned

help with package "simsalabim"
...ckage "simsalabim".
I ran command decompSSA with L = length(Amps)/5
The reason is that I have SSA/MTM toolkit running in Mac/OS. SSA/MTM documentation, relative to SSA, recommends that N/10 <= L <= N/5. Documentation of simsalabim package recommens that L=N/2
I ran the command getSignal and felt uncomfortable at picking values for parameters C0 and r0.
I would appreciate some suggestion/guidelines because these values seem to influence the trend extraction.
I chose C0=0.0005, r0=0.0005 which are both below the Nyquist frequency 1/Amps.dc$L = 0.0007223346

[Q] raw -> gpr in aroma package
Hi.
Is it possible to make gpr from raw?
library(aroma)
#read gpr file
gpr <- GenePixData$read("gpr123.gpr", path=aroma$dataPath)
# gpr -> raw
raw <- as.RawData(gpr)
# raw -> ma
ma <- getSignal(raw, bgSubtract=FALSE)
ma.norm <- clone(ma)
#normalization
normalizeWithinSlide(ma.norm, "s")
#ma -> raw
raw2 <- as.RawData(ma)
I want to make gpr data from raw2 and then I want to write new gpr(
write(gpr,¡±result.gpr¡±)).
Is it possible?
Can anyone help me with this?

Why does verifyFunction dislike this?

[LLVMdev] int to StringRed conversion
I think the better solution should be:
LLVMContext& C = is->getContext();
Value *values[] = {
ConstantInt::getSigned(Type::getInt64Ty(C), *scsr*),
MDString::get(C, *"path"*)
};
lnstr.setMetadata(*"your_analysis_name"*, MDNode::get(C, values));
So that you can take advantage of the type system of LLVM bitcode, and
don't have to cast the integers from/to strings by yourself.

IRBuilder constraints

is, that for a bit shifting operation a global variable address is used as

The IRBuilder code for the memread instruction is the following for both

llvm::Value* op1 = llvm::ConstantInt::getSigned(irb.getInt32Ty(),

auto* pt = llvm::PointerType::get(op1->getType(), 0);

[LLVMdev] Initializing GC roots
Hello all,
I set: InitRoots = true; in my gc plugin as i want the roots to be
initialized to the "null" value.
Is there a way to define which value should be the initial one? For
example, i would like to initialize my roots to -5 (tagged, null value
for the GC in my runtime system) instead of 0.
Ofcourse, i could do it in the frontend (storing -5 to all GC roots),
but i was wondering

[LLVMdev] int to StringRed conversion
Hello everyone,
I have an integer and I want to convert it to StringRef in order to set
metadata.
setMetadata->(StringRef, MDNode*);
It is there a native LLVM way to do it?
1. In the llvm::APSInt Class is toString() method, which seems it is not
for this purpose
2. itoa and string are not part of LLVM
3. stringstream is not part of LLVM
4. to_string is not part of LLVM
5. any casting method?
