question on the signature of malloc
Hi all,
consider the following function from Core.cpp in LLVM 9.0.0:
LLVMValueRef LLVMBuildMalloc(LLVMBuilderRef B, LLVMTypeRef Ty,
const char *Name) {
Type* ITy = Type::getInt32Ty(unwrap(B)->GetInsertBlock()->getContext());
Constant* AllocSize = ConstantExpr::getSizeOf(unwrap(Ty));
AllocSize = ConstantExpr::getTruncOrBitCast(AllocSize, ITy);

[RFC] IRBuilder polymorphism: Templates/virtual
Hi,
The IRBuilder is currently templated over a constant folder, and an
instruction inserter. https://reviews.llvm.org/D73835 proposes to move this
towards using virtual dispatch instead. As this is a larger design change,
I would like to get some feedback on this.
The current templated design of IRBuilder has a couple of problems:
1. It's not possible to share code between use-sites that

[Debug] Elide the unconditional branch instructions
This email is related with the code of commit: http://lists.llvm.org/pipermail/llvm-commits/Week-of-Mon-20120409/140650.html. This commit will let our unconditional branch instruction not be deleted when its successor is the nature layout and its basic block's instruction only one instruction.
However, I have some concerns about it, especially in the debug mode. Let me show you some

[PATCH] strlen -> strnlen optimization
This addition converts strlen() calls to strnlen() when the result is
compared to a constant. For example, the following:
strlen(s) < 5
Becomes:
strnlen(s, 5) < 5
That way, we don't have to walk through the entire string. There is the
added overhead of maintaining a counter when using strnlen(), but I
thought I'd start with the general case. It may make sense to only use
this

Sorry, these IRBuilder methods are really in IRBuilderBase.

[LLVMdev] type-system-rewrite branch landing tomorrow
Attached is a patch for the non ExceptionDemo demos which gets rid of the old
const qualifier usage for Type. Although I recently commited the ExceptionDemo
changes, I did not want to touch code that I did not "own" without other's approval.
Even though trivial, I did not test this patch.

[LLVMdev] CreateGlobalStringPtr giving linker errors
Hi,
I am trying to use some LLVM API in my C++ code, and I end up getting

is LLVM 3.0.

Probably your g++ compiles x86_64 binary by default, but i686 dylib is supplied?
Try:

Orc JIT v2 breaks OpenMP in 11.x branch?
Hi Geoff,
Nothing in that backtrace leaps out at me. Based on the stack trace and
description my first guess would be a clang misconfiguration rather than a
JIT bug.
How is that clang invocation being made? Is it from inside a callback from
ORC, or is it before you add your module to the JIT?

[EXTERNAL] Re: Orc JIT v2 breaks OpenMP in 11.x branch?
Hi,
That patch was from an ongoing effort to consolidate OpenMP generation in clang. If memory serves the implementation there is still a little incomplete. It's supposed to use types from OMPConstants rather than ones it defined itself and the methods used to create the functions shouldn't need to be static. However attempting this caused a lot of errors so there might be an underlying

Thanks, Joseph and Johannes.
I have not merged in anything, I am using the code from the repository
as is. What is this -debug-only option, and to whom would I pass it? I
am running our own JIT application, which uses clang to compile
modules on the fly via clang::CompilerInstance::ExecuteAction().
Working on the assumption that there is a mismatch in the declared
type of an OpenMP runtime

[EXTERNAL] Re: Orc JIT v2 breaks OpenMP in 11.x branch?
Yeah, I remember encountering that error before when getting it to pass the libomp test suite. If you have a struct named "ident_t" somewhere the compiler will rename it because of the conflict with the runtime declaration. This should be solved by casting the usage to the function type found in the definition (i.e. bitcasting a struct.ident_t.21 to struct.ident_t) which solved the
