Hello, I'm eager to get to know Clang+LLVM but I'm having some problems generating debug information that force llc.exe to crash. I'm running from the command-line on Windows 7 with clang+llvm versions 2.9 downloaded from the website. The input file is main.c:      void mainCRTStartup()      {      } This is compiled to intermediate with debug symbols using:      clang -g -O0 -c

Hello, Recently I found binaries produced with LLVM impossible to debug under Windows. This was probably related to the following bug: http://llvm.org/bugs/show_bug.cgi?id=13636 Asm generated from .ll files revealed that some offsets to debug information were incorrect: they were absolute instead of relative to their sections. Following patch seemed to have repaired the problem, so I'm

I was looking into the AsmPrinter and the method EmitSectionOffset which contains this code: -------------------------------------------------------------------------------- // If the section in question will end up with an address of 0 anyway, we can // just emit an absolute reference to save a relocation. if (Section.isBaseAddressKnownZero()) { OutSt...
