I don't think that GDB support is even present in the latest version of the old JIT in trunk. It used to have code to register emitted functions with GDB in a way that let GDB find the function name and EH frame information, but that got taken out back in January (r147615). As it stands now, I don't think GDB would provide any useful information at all about code emitted by the old JIT. MCJIT, on ELF platforms at least, registers emitted code with GDB for full source level debugging (when debug info is available). -Andy -----Original Message----- From: llvmd...

Oops, sorry hit send too early -- meant to just make a draft email. I'm still looking through, but so far I hadn't seen many of its methods being used...

Perhaps it could have been removed when ELFWriter was removed in r147615? http://llvm.org/viewvc/llvm-project?view=rev&revision=147615 - Jan On Fri, Oct 26, 2012 at 4:41 PM, Jan Voung <jvoung at chromium.org> wrote: > Oops, sorry hit send too early -- meant to just make a draft email.
