Liu, This is likely a better solution for you - you do not want to mess with the scheduler unless you really have to ;) Sergei --- Qualcomm Innovation Center, Inc. is a member of Code Aurora Forum, hosted by The Linux Foundation > -----Original Message----- > From: llvmdev-bounces at cs.uiuc.edu [mailto:llvmdev-bounces at cs.uiuc.edu] > On Behalf Of Krzysztof Parzyszek > Sent:

You could derive your own class from TargetPassConfig, and add the annotation pass in YourDerivedTargetPassConfig::addPreEmitPass. This will add your annotation pass very late, just before the final code is emitted. If you're using the X86 target,

Hi Danny, Thanks for that :) However I've just updated the prototype patch to NewGVN and it didn't need any API changes - all I rely on is GVNExpression. Hongbin, I wanted to explain a little about what GVNSink can currently do, what it was designed for and hopefully how to make it handle your testcase. *Background* Common code sinking is more difficult to efficently do than one might

Hi, guys. I'm a newbie to LLVM and have a very simple question. Which instructions should I use (in terms of IRBuilder calls) to allocate an array of bytes in stack (alloca?), then to work with it (from a given offset) as with integer (bitcast?). I mean something like that: unsigned char var[8]; unsigned int offset = 3; int val = *(int*)(&var+offset); /* read */ *(int*)(&var+offset)

quite some speed improvement indeed. attached the updated patch to apply to svn/trunk. j -------------- next part -------------- A non-text attachment was scrubbed...
