I have a database like this: "kol1";"kol2";"kol3" ... "2";"5";"9" "9";"6";"6" "4";"6";"5"... I looking for a kod in R which let mi aviod in column unnecessary value, for example number "9". So, if I have: Kol1 2 9 4 4... after loop in R I would like to get my column like this: Kol1 2 4 4...

Hi, Within a basic block I can remove unnecessary register copies + zero sign extensions of unsigned-8bit-loaded values by implementing isZExtFree() for ISD::LOAD nodes. ...But not between basic blocks. The first block does a CopyFromReg of the unsigned-8bit-loaded vreg1 into a new vreg2. The second block then does a unnecessary zext to vreg2. W...

Hi Keir, csched_load_balance is used to see if there are higher privileged vcpu in other physical processors'' runnable queue, if there is, then migrate this vcpu to this physical processor. But at following scenario, this vcpu migration is unnecessary. 1. idle_vcpu0 is running on lp0, hvm_vcpu is in lp0''s runnable queue, this happens when hvm_vcpu is just being woken up, 2. idle_vcpu1 is running on lp1, there are no vcpu in lp1''s runnable queue, idle_vcpu1 calls scheduler to try to find vcpu in other physical processor...

In the file \lib\Support\Process.cpp on line 60, it seems as though an unnecessary heap allocation and memory leak occurs. This is the offending code: static TimeValue getElapsedWallTime() { static TimeValue &StartTime = *new TimeValue(TimeValue::now()); return TimeValue::now() - StartTime; } The issue is that the StartTime variable's value is allocated on the heap...

Hi, With LTO, it seems that compilers should have the information to decide whether to inline a function or not. In this case, is it unnecessary to specify functions as inline in C/C++ code? -- Regards, Peng

Yes, the later pass is the coalescer. It would be worthwhile to understand why it is not coalescing the copies. Dan
