404s within LLVM documentation
Hi all,
I'm currently in the process of updating the Kaleidoscope tutorials (first
and foremost, the ORC/BuildingAJIT ones), and I've noticed a fair few 404s
which are lingering within the current visible documentation. Some of these
don't seem to have linked to existing pages for a while.
I was wondering if there was a way to set up a check in the buildbot to
ensure that

Errata: The JIT tutorial
For example, the illustrate part says "ES.getMainJITDylib().setGenerator"
while the full code list says "ES.getMainJITDylib().addGenerator", I guess
the API is changed, the tutorial part is up to date while the full code
list leaves to the old version.

Moving docs?
Hi llvm-admin, (cc llvm-dev for visibility)
We’re working on some improvements to the documentation, and want to move things (e.g. the Kaleidoscope tutorial into a subdirectory) around without breaking any links to it. Is there a way to do forwards on the web page that you prefer?

404s within LLVM documentation
Patrick, how long does the crawl take? I suspect if we fixed internal
documentation links so that they point to local copies of documentation
when building locally it would be quite quick (no actual idea though). That
in turn would probably make it feasible to add to the existing
documentation build bots, I think.

Errata: The JIT tutorial
Hi Yafei,
First 2 chapters of the tutorial is up-to-date with ORC v2 APIs. I hope
nothing changed in docs and code.
Did you got compilation errors?

(How) Can I add C standard libraries to JIT?
Hi Yafei,
As david told, you can make the symbols of your host process visible to the
JIT'd code through DynamicLibrarySearchGenerator::getForCurrentProcess.

kaleidoscope ch4 jit example regression?
https://llvm.org/docs/tutorial/LangImpl04.html has an example where
the function `foo` gets redefined, and the JIT returns evaluation of
the latest definition. I thought my code was wrong, but it seems that
the binary produced by `ninja Kaleidoscope-Ch4` has the same bug.
Granted, my LLVM checkout is from Nov 3 2018 (r346062). Is this a known issue?

How to implement function pointer?
Hi, I'm learning to use llvm api to generate IR code, I got two good
tutorials, https://llvm.org/docs/tutorial/ and
https://www.ibm.com/developerworks/library/os-createcompilerllvm1/index.html,
but non of those showed how to implement a function pointer(or at least
there is but I didn't find out).
For example I got a c style code like this:
int foo(int i) {
return ++i;
}

strsplit and regex
Hi All,
Is there a means to extract the "10" from "23:10:34" in one pass using
strsplit (or something else)?
tst <- "23:10:34"
For example my attempt
strsplit(as.character(tst),"^[0-9]*:")
gives
[[1]]
[1] "" "" "34"
Obviously it is matching the first two instances of [0-9]. Note that
there may be only one digit

"corrupted size vs. prev_size" when calling ExecutionSession::lookup()
Hi, I wrote a compiler that generate IR code and run it on the JIT, and
there randomly crashed due to "corrupted size vs. prev_size" depends on the
IR code generated from the source code.
Here's how I created the JIT:
llvm::InitializeNativeTarget();
llvm::InitializeNativeTargetAsmPrinter();
llvm::InitializeNativeTargetAsmParser();
// create jit

kaleidoscope ch4 jit example regression?
Hi Nick,
I was not aware of it, but it makes sense given the recent switch to ORC2, which has different symbol resolution rules.
I am out on vacation this week, but will take a look when I get back and see if I can restore the old behavior.
Cheers,
Lang.

Correct, with a couple of nit picks.
Relocation isn't an optimization the collector performs. It's a key
primitive the collector is built upon. Being unable to relocate is not
an allowed state. (i.e. pinning can't be required by the compiler)
When you talk about variables, that's true for the *source* language and
for the *abstract* machine before lowering. After lowering

Errata: The JIT tutorial
In the Tutorial of the JIT https://llvm.org/docs/tutorial/BuildingAJIT1.html,
illustrations and the full code listing are not the same, and the full code
listing will not compile, this will make a lot of trouble to beginners
since the JIT API is changing all the time.

(How) Can I add C standard libraries to JIT?
When I declare some functions in my IR code which belongs to the C standard
library(printf for example), the JIT will report that symbol cannot found.
So is there any way I can add these libraries to my JIT?
P.S. When I using lli, the printf will work, I guess lli is a JIT(right?)
and it somehow knows where to find the symbol printf

Not yet unfortunately. I've had my head down working on a jut-linker

LLVMTargetMachine with optimization level passed from clang.
I see the BackendUtil.cpp of Clang creates the TargetMachine with the
optimization level based on below mentioned logic
CodeGenOpt::Level OptLevel = CodeGenOpt::Default;
switch (CodeGenOpts.OptimizationLevel) {
default: break;
case 0: OptLevel = CodeGenOpt::None; break;
case 3: OptLevel = CodeGenOpt::Aggressive; break;
}
As per my understanding, the correspondence between

Legacy Loop Pass Manager question
Hi,
If we add multiple loop passes to the pass manager in
PassManagerBuilder.cpp consecutively without any func/module pass in
between, I used to think they would belong to the same loop pass manager.
But it does not seem to be the case.
For example for this code snippet
PM.add(createIndVarSimplifyPass()); // Canonicalize indvars
MPM.add(createLoopIdiomPass()); //
