[LLVMdev] LLVMContextImpl.h not installed?
Hi all, I 'd like to fetch a list of structures, and found that it could be done via LLVMContextImpl *pImpl = Context.pImpl; pImpl->AnonStructTypes This however needs the inclusion of LLVMContextImpl.h, which is not contained in the includes dir, but in the lib/IR dir (next to the .cpp files) and is not installed under /usr/local/include... Whats the reason for this? Isn't it

[LLVMdev] Analysis of polly-detect overhead in oggenc
...elf and can verify that for oggenc 16x, your patch reduces the scop-detection time from 90 seconds (80 %) to 0.5 seconds (2.5 %). I think there are two problems: 1) The cost of printing a single LLVM type/value increases with the size of the overall Module. This seems to be because TypeFinder::run() is called each time, without caching in place. The cost of TypeFinder::run() increases with the size of the module, as it basically just performs a scan on the entire Module. 2) We are formatting the failure messages during normal compilation, even though they are onl...

llvm extract struct elements and struct size in C++
...t; I want to create a database of all structures (global and local) > defined and being used in my program. Eg. < A , <int32, int32> , B , > <int32, bool , char *>>. I think the closest LLVM has is either Module::getIdentifiedStructTypes or the class it actually uses: "TypeFinder". Beware though, struct types may not have a name, and even if they do it won't necessarily correspond to the original C or C++ name in any meaningful way. These both return an std::vector<StructType *> in some form, which you can probe for the fields (they'll definitely be un...

[LLVMdev] Analysis of polly-detect overhead in oggenc
Hi all, I have attached a patch file to reduce the polly-detect overhead. My idea is to avoid calling TypeFinder in Non-DEBUG mode, so TypeFinder is only called in DEBUG mode with the DEBUG macro. This patch file did this work with following modifications: First, it keeps most of string information by replacing "<<" with "+" operation. For example, code like this: INVALID(C...

llvm extract struct elements and struct size in C++
LLVM Newbie here. I have the following C++ program using namespace std; struct A{ int i; int j; }; int main() { struct A obj; obj.i = 10; obj.j = obj.i; return 0; } Using clang++, I can see that LLVM IR contains struct field as below %struct.A = type { i32, i32 } I would like to obtain the structure elements using LLVM Pass. I write the following program - that iterates

Question about llvm::Value::print performance
...::Module (linked module with lots of types/...). I started with plain ::print and switched over to http://llvm.org/docs/doxygen/html/classllvm_1_1Value.html#a04e6fc765eeb0c4c90ac5d55113db116 with a ModuleSlotTracker I pass in myself to avoid some complexity. Still now I have the issue that the TypeFinder::run and related that is done internally by each print still is 99% of my program runtime. (at least perf tells me that) Is there any clever workaround for this? I looked a bit through the sources but it seems that no API is exported that would allow a faster print call. Given I want the outpu...

[LLVMdev] Iterate through a Module's StructTypes
Hello, I'm updating a legacy code using LLVM 2.5 where it has an iteration through a Module's TypeSymbolTable to process each StructType. In LLVM 3.4, TypeSymbolTable has been removed. I can only find the LLVMContextImpl instance of a Module's LLVMContext which has AnonStructTypes and NamedStructTypes two maps. However, LLVMContextImpl is an opaque class which cannot be directly
