[LLVMdev] Exception handling question
I think so. It also fails the same way on LLVM trunk from last week.
The full backtrace is below. It appears that frame #3 is a compilation
of __l_personality() and frame #14 is a compilation of f(). The
compilation of __l_personality appears to have been triggered by the
need to output DWARF information for f().

[LLVMdev] Exception handling question
Interesting. Was this the reason you were getting the recursive compilation error in JIT::runJITOnFunctionUnlocked(...) (isAlreadyCodeGenerating)?
Do you have the time to try your test with 2.7?

[LLVMdev] Exception handling question
I've worked around this issue in my test case by simply calling my
personality function on program to ensure it's JIT'ed before any unwind
happens.

Nope. You cannot place a call instruction into one module whose

[LLVMdev] Exception handling question
Hi James,
Just wanted to update you. As you implied the problem here is that
the personality function has to be jitted before the code that contains
the corresponding llvm.eh.selector intrinsic instruction is jitted. I verified
this by creating a generated version of the personality function which unless
I jitted first, gave me the same error when running the code. Since you are using
tools

[LLVMdev] another experimental patch for bug 2606
No problem I'll drop this from our discussion as it really is only germane to my
learning path and imagination. :-) I do at this time still have this concern of
allowing a user (developer) the right to turn this "cross module linkage" off, but
I'm still in the process of understanding your previous comments on this.
Thanks again for the help and time by the way.

[LLVMdev] RFC: Exception Handling Rewrite
Hi Eli
So I found this in Attributes.h:
const Attributes UWTable = 1<<30; ///< Function must be in a unwind
///table
What does this mean? In particular what does it mean not to add this as
a function attribute to a function? I'm obviously going down the wrong road in
my interpretation, as I

No, there is no magic. :-)
To me though, the tools are magic, because I have no clue what they are doing without looking at them and using them.
As their function is not germane to my current endeavors, I hope to learn about them from this list, and most likely from
your postings. I know it is a common approach, but to me I think bitcode generation to JIT runtime is a a cool feature of
LLVM.

[LLVMdev] Operations on constant array value?
Sorry to keep this thread alive, but I'm learning so ...
There is more. The doc for GlobalValue::LinkageTypes or the C API LLVMLinkage is not as clear as the
lang ref manual. See: http://llvm.org/docs/LangRef.html#linkage. I'm pointing this out because something
like LinkerPrivateLinkage (LLVMLinkerPrivateLinkage), or another one, might be more appropriate to
your throw away use case (if

[LLVMdev] Exception Implementation Example added to Wiki
If the powers at be want this, I could easily transform the source to the LLVM coding standards, and add
the necessary portable UNIX support--someone else would have to add non-UNIX support although the
System library probably helps with this. However I'm guessing the LLVM release flux of the exception system,
along with a lack of universal platform, dwarf JIT support might be a hinderance in

It already exists; there's some limited documentation in the LLVM
source, but Rafael apparently forgot to add it to LangRef...

[LLVMdev] getAnalysisIfAvailable<>(...)
Hi!
If a pass is required then it makes sense to
getAnalysis<DwarfWriter>(). getAnalysisIfAvailable<>() is used for
cases where a pass want to take advantage of (or fix up) info only
*if* it is available.
If you prepare a patch to fix getAnalysisifAvailable<>() uses (e.g.
DwarfWriter requests you mention below) then I'll apply it.

[LLVMdev] Debugging of LLVM-IR
Unfortunately, the current gdb support doesn't include line numbers.
It'll tell you what function it crashed in and the stack trace though.
Line numbers will probably come when the llvm-mc project is merged into the JIT.
