...ething like "load i32* getelementptr ( %struct @x, i32 0, i32 2)". Now you want to replace the global @x with a local alloca %x (assuming all the appropriate safety checks are done). "load i32* getelementptr (%struct %x, i32 0, i32 2)" is illegal; it has to be split into "%loadaddr = getelementptr %struct %x, i32 0, i32 2" and "load i32* %loadaddr". -Eli

Hi folks, I'm still using MCJIT (I know, I know), and I spotted a crash in exception handling when I moved from llvm 3.8 to llvm 3.9. I traced it back to EH frames not being deregistered due to a (typo?) mistake in RTDyldMemoryManager.cpp: void deregisterEHFrames(uint8_t *Addr, uint64_t LoadAddr, size_t Size) override { * registerEHFramesInProcess(Addr, Size);* } ..I overrode the function to call deregister instead of register in my own MemMgr and all's now well. The crash manifests itself as a seg fault when a process causes an exception after JITted code has been removed. Che...

Hi Chris, > > [ Snip replacing constantexprs with instructions ] > Ok, this is not possible in general though, global variable initializers > have to be constants, not instructions. Yeah, so if not all uses can be replaced, my pass will just have to skip the variable. > Is it possible to design the pass to work with both? The general approach > is to make stuff handle

This patch set mainly allows the user to build a seabios or rombios only version of hvmloader. In addition, when building a seabios only hvmloader, Option ROMs like vgabios and etherboot are no longer required, and therefore can be disabled from the build. Dependency on the bcc compiler can also be avoided the same way. v2: Separate patches for separate issues Introduced config option to

Yaron, Did you find a way around the problem? It looks like the problem comes before processFDE because by the time it gets to processFDE the eh_frame data is already corrupted. Does ELF and MachO share the same eh_frame format? I am developing this code in parallel on an Ubuntu Linux system but I haven't tried to run it on there for a couple of weeks. I'll bring it up to date and

...s (at least) __register_frame should be called once and not called on every FDE as in processFDE in RTDyldMemoryManager,cpp does. So RTDyldMemoryManager::registerEHFrames was modified to: void RTDyldMemoryManager::registerEHFrames(uint8_t *Addr, uint64_t LoadAddr, size_t Size) { __register_frame(Addr); } On Windows 7 / MingW (gcc) this completely solved the problems I had with erratic exception behaviour. The second issue is a bit more complicated. With executable files, the linker combines .eh frames with four...

Hi, I’m looking for advice on how to debug a problem with my exception handling code. I’m asking a specific question here - but general advice on how to debug something like this would be greatly appreciated. Is there any way to get a list of landing pad clauses that are active at a particular point in a program? I'd like to get something like a backtrace but listing all active landing pad

Hi, I had similar problems with EH in ELF in RTDyldMemoryManager::registerEHFrames() calling __register_frame(). I'm not sure these problems are related to this problem since your crash happens in RuntimeDyldMachO::registerEHFrames() in its own processFDE (there are two functions named processFDE(), one in RuntimeDyldMachO.cpp and one in RTDyldMemoryManager.cpp) *before*

Hi Folks, I''ve got a 3.9 Tb zpool, and it is casing kernel panics on my Solaris 10 280r (SPARC) server. The message I get on panic is this: panic[cpu1]/thread=2a100a95cc0: zfs: freeing free segment (offset=423713792 size=1024) This seems to come about when the zpool is being used or being scrubbed - about twice a day at the moment. After the reboot, the scrub seems to have
