IMHO, a better solution would have been to add a Pat<> rule to match truncstores and expand them into target store/load/and/or. Pat : <(truncstore16 GPR:$val, MEM:$mem), (store MEM:$mem, (or

Hi all, I'm learning the PTX backend and confused by the following problem. In the constructor of PTXFrameLowering, StackAlignment and LocalAreaOffset are assigned 2 and -2, respectively. Since PTX has neither stack frame nor stack pointer, why StackAlignment and LocalAreaOffset are needed and where does 2 and -2 come from? Any explanation is appreciated. Thank you in advance! Yours

Hi all, In our architecture, there is a set of general purpose registers which could be used to store integer and floating point numbers. My problem is how to correctly specify the type of this register class. For now, its type is specified as i32, and it is problematic if it is used in floating point instructions, since tablegen cannot correctly infer the type information of such a pattern. Here

Hi, I'm writing to ask the differences between a "reserved" register and an "unallocable" register. In X86 backend, for example, the stack pointer register and instruction pointer are reserved but allocatable. In the Doxygen document of function llvm::TargetRegisterInfo::getReservedRegs, it says that a reserved register is one that *has particular uses and should be

Time stamps are correct and my system time is correct. I am now tried to use Sys.setFileTime() to update time stamps as proposed. This does not help. The windows and debian builds give different reports on the time stamp issue. https://win-builder.r-project.org/incoming_pretest/eurostat_3.2.8_20180920_122655/Windows/00check.log

Dear developers, Upon CRAN submission I have bumped into "future file timestamps" warning that I can't solve. I have updated the package as usual, and all checks go through in my system. CRAN reports the following warning however. * checking for future file timestanps ... WARNING Files with future time stamps: DESCRIPTION NAMESPACE README.md The build log is at

Could someone explain to a non-US dummy the following phrases I have seen on the list. "I can provide you with tier 1 termination 6/6. I can blend or NPANXX breakout." "We provide US48 termination, blended rate for 1 MOU and above is .008 with 6/6." What is 6/6? What is US48? What is blended? What is MOU? What is NPANXX breakout? -------------- next part --------------

I am trying to finalize the use of rsync for updatiung a new nfs server before we take the old one offline. I keep getting the following warning during the rsync process: Warning: unexpected rad size of 0 in map_ptr Any ideas where this comes from and how to make it go away? I am using rsync 2.5.2 on Solaris 8 to pull data from rsync 2.5.2 on Solaris 7. Bob roconnor@vectorpartners.com
