similar to: [LLVMdev] numeric limits of llvm Types?

Hi, I have a Type * which may come from an IntegerType as shown below: Type.getIntegerBitWidth() tells me numBits. But how to extract the IntegerType.getSignBit? If pType isIntegerType, I need to know if it is signed or unsigned... How to achieve this? Thx Alex llvm::Type * getRandomValid_IntegerType(llvm::LLVMContext &C) { using namespace llvm; //--- determine num of bits

Hola LLVMers, I'm getting a crash when using ConstantFP::get. I can repro it by adding one line to the Fibonacci example program: int main(int argc, char **argv) { int n = argc > 1 ? atol(argv[1]) : 24; // Create some module to put our function into it. Module *M = new Module("test"); // We are about to create the "fib" function: Function

It's in debug. I'm having a look at the assembler it's producing right now and it's definitely a little odd for what should be a simple assignment in zeroSignificand. ________________________________ From: llvmdev-bounces at cs.uiuc.edu [mailto:llvmdev-bounces at cs.uiuc.edu] On Behalf Of Dale Johannesen Sent: Wednesday, September 05, 2007 2:39 PM To: LLVM Developers Mailing

It prints "0". Calling that inifinity is somewhat of a stretch, isn't it ? What on earth

Hola Dale, I spent some time walking through what's going on with a friend of mine from VStudio. Category is given 2 bits in the APFloat class definition. It's sign extending the enum value for the comparisons when it loads it out of the class, so the 2 becomes a -2 and the comparison fails. He sent me a piece of code which I might be able to use to force the issue. I'll update

Hi, I recently tried to follow the instructions on http://vmkit.llvm.org/get_started.html but all I get is -- snip -- In file included from /home/birdspider/vmkit-test/llvm/include/llvm/Support/SwapByteOrder.h:20: /usr/bin/../lib/gcc/x86_64-unknown-linux-gnu/4.7.0/../../../../include/c++/4.7.0/limits:1404:27: error: use of undeclared identifier '__int128'; did you mean

Yes, that will work. I'll make the change.

This patch supplies software IEEE floating point support. The comment from the patch reproduced below says all there is to say. This patch contains the prior "cleanup" patch; please don't apply that one. Please let me know of any bugs. It is tested reasonably well, but until I put together random tests it's hard to have 100% confidence. Neil. /* A self-contained host- and

getInitializer returns the complete initializer of the global. My globals are complex nested structs, from which I want to extract e.g. one double datafield. Example: >From a struct Stuct having double,array(3xint),float fields, I could extract the second int value using the index sequence 0,1,1 with getGetElementPtr. This gives me a constantPointer, but I would need to get a constInt...

John, you are right. I 'browsed' the doxygen's inheritance diagram. Shouldn't I then be able to cast Constant * to Value*? Plugging the retrieved Constant* (from ConstantExpr::getGetElementPtr) into Instruction->setOperand compiles, but gives me an assertion failure at runtime. I have no access to the code at the moment. I will gather more information possibly tomorrow.

The NIST F77 test suite doesn't seem to be compatible with gfortran at all, so I had to work from my own sample codes, and generate test cases from them. Here's what works now, and I have a separate test case for each of these: statement functions intrinsic functions (print, cos, etc) loops, goto statments scalarized array operations function calls with *no arguments* simple common

Hi all, when e.g. accessing a global variable residing in a structure, the c++API code looks like: std::vector<Constant*> const_ptr_183_indices; const_ptr_183_indices.push_back(const_int32_172); const_ptr_183_indices.push_back(const_int32_184); const_ptr_183_indices.push_back(const_int64_175); Constant* const_ptr_183 = ConstantExpr::getGetElementPtr(gvar_struct_foo,

Hi all, when I have c code like --- c code ------------- struct stest { /* deklariert den Strukturtyp person */ int age; float weight; } foo={44,67.2}; /* deklariert Variable des Typs person */ int main() { callAFunction(foo.weight); ------------------------ The generated c++API code to me seems to be too chatty in the sense that the foo.weight's data
