Hi everyone, vmkit requires to know the size of a jitted method before emitting the method. This allows to allocate the correct size for the method. The attached patch creates this functionality when the flag SizedMemoryCode is on. In order to implement this functionality, i had to virtualize some MachineCodeEmitter functions. Is it OK to commit the patch? Thanks, Nicolas --------------

Thx again Evan for the review. Here's a new patch for the JIT in itself. The major changes are: 1) A JITMemoryManager now has a flag saying "I require to know the size of what you want to emit" 2) DwarfJITEmitter is augmented with GetSize* functions 3) JITEmitter::startFunction checks if the JITMemoryManager requires to know the size. If so, it computes it and gives it through the

Hello everyone! I faced an issue using virt-resize. I have an image with extended -> logical -> pv -> lv -> ext4 (although I think LVM does not matter). And image is 65G virtual size and 1G actualSize. When I call virt-resize to 60G, it blindly copies the extended partition content, but does it non-sparse (resize.ml:1231), irrespective to --no-sparse option. So the destination image is 60G actual size. Is it a bug, or it was made intentionally (why?) ? TY for answers! -- Your sincerely, Maxi...
