Hi, I am trying to implement Available Expressions data flow analysis. I created the following class (I am giving here code snippet.): namespace { typedef DenseMap<Expression, uint32_t> DMTy; //Expression is a class I defined. struct DataFlowValue { DMTy ExprMap; llvm::BitVector* DFV; // Functions operating on the data // bool operator==(const DataFlowValue V) const;

Hi everyone, Here's a patch that enables exception handling when jitting. I've copy/pasted _many_code from lib/Codegen/DwarfWriter.cpp, so we may need to factorize it, but the functionality is there and I'm very happy with it :) lli should now be able to execute the output from llvm-gcc when using exceptions (the UnwindInst instruction is not involved in this patch). Just add the

Here are two minor patches. The first adds an insert method to DenseSet that takes two iterators representing the beginning and ending of a range of items to insert. I lifted the code verbatim from DenseMap.h. The second patch defines DenseMapInfo for chars. This is useful because DenseSet is implemented as a DenseMap of (Type, char), so anyone who uses DenseSet has to define DenseMapInfo for

Cygwin's <stdint.h> defines uint32_t as "unsigned long". I think this is valid, but it causes various problems like this when building LLVM with GCC 3.4.4: .../lib/CodeGen/SelectionDAG/SelectionDAG.cpp:3440: error: call of overloaded `AddInteger(uint32_t)' is ambiguous .../lib/CodeGen/SelectionDAG/SelectionDAG.cpp:1429: error: no matching function for call to `max(long

Dear all, Here's a new patch with Evan's comments (thx Evan!) and some cleanups. Now the (duplicated) exception handling code is in a new file: lib/ExecutionEngine/JIT/JITDwarfEmitter. This patch should work on linux/x86 and linux/ppc (tested). Nicolas -------------- next part -------------- An embedded and charset-unspecified text was scrubbed... Name: jit-exceptions.patch URL:

Looks sane. Thanks.

Hi, I might just be doing something stupid, but when I do $ cmake -DCMAKE_INSTALL_PREFIX=/usr/local/llvm-2.8 -DCMAKE_BUILD_TYPE=Release .. $ sudo make install I don't get the expected headers in /usr/local/llvm-2.8/include/llvm It is simply an empty directory. What am I doing wrong? This is on Mac OS X, CMake 2.8+ Kind regards, Samuel

Hi Evan, My apologies: I've been so excited on sharing the functionality that I forgot to review my patch!
