<p class="MsoNormal">Hello everyone,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I want to use the LLVM to write a JIT client, that works with shared memory. Currently I proceed as following:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I wrote an own class that inherits "<i>RTDyldMemoryManager</i>". The functions "<i>allocateCodeSection</i>" and "<i>allocateDataSection</i>" are allocating local non-shared memory. I store there addresses in a std::vector.<o:p></o:p></p>
<p class="MsoNormal">When the function "<i>notifyObjectLoaded</i>" is invoked, I allocate the shared memory - I'm getting the size from the local non-shared memory - and apply the address mapping.<o:p></o:p></p>
<p class="MsoNormal">When the function "<i>finalizeMemory</i>" is invoked I copy the code from the local non-shared memory to the shared memory but only one time.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">So far so good, this works actually good! Yippie x3<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">BUT... There is one problem. The shared memory can't be dynamical adjusted. So if I add another module to the current module, then I would go through this process again! Not the "<i>finalizeMemory</i>" process though, but I would allocate
another shared memory. This is not what I want! Currently I use the linker first, to work around this problem, but this will not help me if I add object files or libraries to the JIT process - or does it?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">So is there any way to work around this?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Kind greetings<o:p></o:p></p>
<p class="MsoNormal">Björn<o:p></o:p></p>
