I''m running Xen 4.1 (4.1.3-3ubuntu1.3) on an Ubuntu 12.10 server with an AMD FX-8150 processor (8 cores) and 16 GB of RAM. When I boot the server, Xen sees only 3 GB of RAM (instead of 16 GB). If I try to create a domU with more than about 1.5 GB of RAM, the create fails with messages saying it "could not allocate memory for HVM guest". Here''s the output when I do

...ble for multiple free's to be inserted on the path from malloc to an exit. For example, in the following CFG: BB10 (malloc) / \ BB11 BB12 ... / \ / \ ... \ / \ / \ / BB13 BB14 BB15 | ... | / BB16 The block BB10 dominates BB11, BB12 and BB14. The dominance frontier of BB10 contains BB13, BB15 and BB16. So if the predecessors of the dominance frontier contains BB11, BB12 and BB14. If a call to f...

Try breaking the critical edges (-break-crit-edges). This way, a new block will be created between BB13 and BB11 (call this BB11.break) and BB15 and BB12 (call this BB12.break). The predecessors of the dominance frontier will, thus, be BB11.break, BB12.break, and BB14. When we enter through a block with a call to malloc(), we will end up in one of the blocks in the dominance frontier (kind of). These blocks must have multiple predecessors, else it would not be in the dominance frontier. If a predecessors of these blocks has only one successor, then that success...

Hi Henrique, Thanks for the quick reply!

Greetings Flac-landers, I have a brand new puter with xp pro 2002 sp2. I downloaded flac-1.1.4b and installed, but when I ran the installed software, it told me that it was unable to run as I do not have mscomctl.ocx on my system. I searched my puter and indeed it is not on it anywhere. I looked all over the site for the prerequisites needed to install, but did not find them. Can someone

Hi Hisham, Most likely the basic blocks are the headers of two different loops. Try running viewCFG() on the function in question to see if this is the case.

Hello, I have a question regrading the analysis pass that generates loop info from an .ll code. My previous understanding was there will be just one loop header(in the loop info) for a particular loop. But, when i use isLoopHeader() member function from the loop info class I get 'true' return value for two different basic blocks. Note both basic blocks are loop conditional block(break
