Hi all, I tried to use std::to_string somewhere and one of the bots yelled at me [1] because it couldn't find it. Searching through the mailing lists reveals a long stream of fixup patches trying to avoid std::to_string, but there are uses of it in tree in the AVR and Hexagon backends, libFuzzer and the Gold plugin. I can only imagine they got away with it because the particular bots that

I'm fairly sure the problem is that we still support building with gcc 4.8.x, and that version of gcc did not have std::to_string. It is not just an NDK issue. -Hal On 05/17/2017 06:05 AM, Pavel Labath via llvm-dev wrote: > Hi Diana, > > I am responsible for that bot, and probably a great number of those fixups. > > The root of the problem is that android NDK comes with a

Hello everyone, I have an integer and I want to convert it to StringRef in order to set metadata. setMetadata->(StringRef, MDNode*); It is there a native LLVM way to do it? 1. In the llvm::APSInt Class is toString() method, which seems it is not for this purpose 2. itoa and string are not part of LLVM 3. stringstream is not part of LLVM 4. to_string is not part of LLVM 5. any casting method?

I just accidently sent a partially complete email, so this contains the rest (sorry!) I'm working on translating llvm's optimized intermediate code to another compiler's intermediate code, and I'm working on the PHI instruction. Here's an example phi instruction to help explain what I'm trying to do: %inc25 = phi i32 [ 1, %entry ], [ %inc, %for.body ] What I would want to

Hi, I think you may try to use llvm::Twine(int). For example, to convert 30 to string, you can use: Twine(30).str() To convert the string back to integer, you can try the StringRef::getAsInteger(unsigned, APInt &). For example: APInt i; str.getAsInteger(/*radix=*/ 10, /*output=*/ i); Sincerely, Logan On Thu, May 2, 2013 at 9:53 PM, Alexandru Ionut Diaconescu <

I think the better solution should be: LLVMContext& C = is->getContext(); Value *values[] = { ConstantInt::getSigned(Type::getInt64Ty(C), *scsr*), MDString::get(C, *"path"*) }; lnstr.setMetadata(*"your_analysis_name"*, MDNode::get(C, values)); So that you can take advantage of the type system of LLVM bitcode, and don't have to cast the integers from/to strings

I have a model where I want to change the display for a single attribute such that if the value is an integer, it displays with no decimal point (e.g. "1"), but if it is non-integer, it displays with a decimal point (e.g. "1.25"). The easiest way to do this seems to be if I could override the to_string method for my_model.my_attribute.to_s. Is there a way to do this? Or

Is there is minimum required version for GCC to build LLVM from the head revision? I have GCC v4.9.3, but 'Tools/sancov/sancov.cc' won't build because 'std::to_string' does not exist. When running CMake it did not flag GCC v4.9.3 as too old, and it is passing the '-std=gnu++11' option, but apparently this version of GCC is not fully C++ 11 compliant, or at least

The problem is that I want to pass only srsr which is an int. "marked" was just an example :) Thanks you!

TargetMachine::addPassesToEmitFile(..) requires as its 2nd argument an raw_pwrite_stream. Is it possible to create such a thing which either writes into a standard string or streams to outs() ? Thanks,

Yes, it sounds good. I can try tomorrow. Thank you for your advice !

Since values are now returned as strings in Python2 and Python3, treating them as bytes in Python 3 would break tests. --- python/t/210-setvalue.py | 12 ++---------- 1 file changed, 2 insertions(+), 10 deletions(-) diff --git a/python/t/210-setvalue.py b/python/t/210-setvalue.py index 9d93519..2ee7ac5 100644 --- a/python/t/210-setvalue.py +++ b/python/t/210-setvalue.py @@ -47,20 +47,12 @@

Hi, I don't see a way to convert an Instruction to a string or const char *, although '<<' works on it. http://llvm.org/doxygen/classllvm_1_1Instruction.html How to figure this out? Thanks. -- Regards, Peng

I would normally do that in C++ by using the StringStream class, but the LLVM coding standards discourage using that class. The same coding standards suggest to use llvm:StringStream instead, but I cannot find that class anywhere; furthermore, the header file where it was supposed to

hi Sean Silva: i really appriciate for your reply. but you konw that "dump()" instruction can print "%4" in the screen and each time print the same name "%4" not "%5" or "%6" for the same unnamed value. so there must be a way to determinate it. if "dump()" instruction can print it on the screen, can i find some way to store it in a char *

Hi Johan, ld64 only calls functions from llvm/include/llvm-c/lto.h (defined in llvm/tools/lto/lto.cpp) For instance ThinLTOCodeGenerator::addModule is called through thinlto_codegen_add_module(). Apple hasn't released the code for ld64 in Xcode 9 yet, did you check if it is fixed in Xcode 9? (I think I remember fixing it in ld64 but I'm not totally sure...). >From what I can see

Hi, This patch adds R600/SI disassembly text to compiled object files, when a code dump is requested, to assist debugging in Mesa clients. Here's an example of the output in a Mesa client with a corresponding patch and RADEON_DUMP_SHADERS set: Shader Disassembly: S_WQM_B64 EXEC, EXEC ; BEFE0A7E S_MOV_B32 M0, SGPR6 ; BEFC0306

Hi, I am trying to generate the DFG of machine functions. Initially, I added a pass to generate the DFG of LLVM IR functions. This was based on the mail thread - http://lists.cs.uiuc.edu/pipermail/llvmdev/2009-September/025582.html. This pass worked fine and I was able to generate DFG of LLVM IR functions. Later, I ported the DFG pass code for machine functions. I ported the InstIterator.h
