However, I think this is something that needs to be consistent across all of LLVM and should be in the coding standard. StringRef::getAsInteger() is an example documented to return true if there was an error parsing the string. Mapping success/error onto a bool will always be ambiguous.

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?

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 < alexandruionutdiaconescu at gmail.com> wrote: > Hello everyone, > > I have an integer and I want to con...

Hello, Mr. krzysztof I have seen similar question asked by you on llvm group. Could you please help me here to address this issue. i am trying to construct a register of size 65536 bit by combining 2 registers of 32768 bits. both the 32768 bit registers are different so i have to use the following method let SubRegIndices = [sub_32768bit, sub_32768bit_hi], CoveredBySubRegs = 1 in but i am

Hi All, Clang pop up with the "error: invalid integral value" diagnostics twice ,when you enable the optimization through -O with a non-integer value i.e -O<non integer> as show below $ clang -Of -S test.c error: invalid integral value 'f' in '-Of' error: invalid integral value 'f' in '-Of' Attached patch fix the issue as $ clang -Of -S

Hi LLD developers, I'm about to make a change to invert the return value of Driver::parse() to return true on success. Currently it returns false on success. In many other functions, we return true to indicate success and false to indicate failure. The inconsistency is confusing, and fixing it should improve code readability. -------------- next part -------------- An HTML attachment was
