[LLVMdev] Liveness information still usable after register allocation?
Hi all, Sorry to bother those not interested in this problem. I have a problem while I want to reuse the liveness information after register allocation. When I use the livein_begin() from MachineBasicBlock to get the live-in registers after register alloction. I found that the liveness information is sometime incorrect. For example, some registers should be live-in to the machine basic block as

[LLVMdev] <IsKill> getting from MachineOperand is just <Used> attribute from logic.
Hi, I have ported LLC to a risc cpu. It can pass benchmark that I have at current. But I want do some optimization after register alloction by adjusting register using. I scan MachineBasicBlock to analyze operand's IsKill, IsDead , IsDef attribute to get a physical register's liverange. But I get a strange case at MBB.jpg. R4 is marked <kill> at MBB0. If I scan R4's

Maintaing Quotas
We have our user set up with quotas on RedHat Linux server(5.1). It works under the normal linux enviroment. BUT when we use SAMBA to get the user's home directory mapped to drive letter on a WINNTmachine (4 with SP 3) it doesn't maintain the quota. After using all the allocted space user can still copy files to that drive which is mapped for user's home directory. Does anybody else had the same problem and if they have can they please help us. Many thanks Sarabjit

You can also look at RegisterScavenging.cpp and MachineVerifier.cpp. They are doing the same

[LLVMdev] LLVM ERROR: ran out of registers during register allocation
...registers in the PTR regclass is reserved for the frame pointer, leaving only one register to access both x and y[i] in the code above, which seems to confuse the regalloc. Implementing getLargestLegalSuperClass() sort of helped for simpler functions, but not for this one. This code can be register-allocted if the addresses of both x and y[i] are cross class copied to DREGS registers to temporarily store these values and then when required copied back to the the register in PTR to access them in memory. Any help for a solution or a workaround will be greatly appreciated since this problem is severily...

Samba 4.7.9 dbcheck error
I had a small peak at your patch. This also applies to samba 4.8.5? Now, basicly, i dont know anythis what that patch is doing, im not a coder, i can read it a bit. But if did read it correct, its about rID pool alloctions where rID = 0 ? Like this: (dn: CN=RID Set,CN=DC2,OU=Domain Controllers,) rIDAllocationPool: 2100-2599 rIDPreviousAllocationPool: 0-0 rIDUsedPool: 0 rIDNextRID: 0 And on

[LLVMdev] FP emulation
Hi, I'm now ready to implement the FP support for my embedded target. My target supports only f64 at the moment. Question: How can I tell LLVM that float is the same as double on my target? May be by assigning the same register class to both MVT::f32 and MVT::f64? But FP is supported only in the emulated mode, because the target does not have any hardware support for FP. Therefore each FP

BUG_ON in virtio-ring.c
Hi, I'm hitting this bug with both ext4 and btrfs. Here's an example of the backtrace: https://gist.github.com/vzctl/e888a821333979120932 I tried raising this BUG only for direct ring and it solved the problem: - BUG_ON(total_sg > vq->vring.num); + BUG_ON(total_sg > vq->vring.num && !vq->indirect); Shall I submit the patch or is a more elaborate fix

[LLVMdev] tblgen multiclasses
Hi Chris, Thanks for this info. This provides even better and more advanced examples of multiclass usage! But your previous explanations were so good that I implemented in my backend last week almost the same that you've done now in the X86InstrSSE.td. I even introduced isCommutable parameter to indicate this property, just as you did. So, by now integer arithmetic and general purpose

Improved version of Rprofmem
The Rprofmem facility is currently enabled only if the configuration option --enable-memory-profiling is used. However, the overhead of having it enabled is negligible when profiling is not actually being done, and can easily be made even smaller. So I think it ought to be enabled all the time. I've attached a patch doing this, which also makes a number of other improvements to Rprofmem,
