I suppose, CentOS 7 ships with DVD and minimal version. While the minimal version is just 700M, what makes the minimal along with a GUI about 4.3 GB. Isint it too huge for an OS ? -- Cheers -- S.Ramaseshan Engineer fractalio.com ramaseshan at fractalio.com

How is bc_memopv4i32 defined? The bitconvert in the tablegen output is marked isInt, which means it's the node that didn't get inferred.

Hi all, I want to match addition with 16bit integers. So I define a pattern fragment as follows: def simm16 : PatLeaf<(imm), [{ return isInt<16>(N->getSExtValue()); }]>; Now I am confused between (add R32:$dst, simm16:$im) and (add R32:$dst, (i32 simm16:$im)). Do both of them match the same pattern? Are they equivalent? If not what is the difference? I am also confused as to how ValueTypes relate to SDNodes as I think we a...

Hello. I've tried to add some simple arithmetic vector operations to the BPF backend available in the LLVM repo. Because I added in BPFRegisterInfo.td another RegisterClass (taken from the Mips backend): def MSA128W: RegisterClass<"BPF", [v2i64, v2f64], 128, (sequence "W%u", 0, 31)>; in order to support vector for example, ADD

.... Would it be possible to detect this before allocating the emergency spill slot, and not request a scavenger at all? > This time there are no new unexpected failures in the regression tests. I noticed that CellSPU has a bunch of isS10Constant() functions. These already exist in MathExtras.h: isInt<10>(). Also, there is no need for 5 overloads of those functions, AFAICT. Please use the MathExtras.h functions, and remove all of the is*Constant functions in SPU.h. /jakob

Hi, attached is a second try for the bigstack patch for SPU, with testcase. It is essentially the patch committed as 97091, and reverted as 97099, but with the following additions: -in vararg handling, registers are marked to be live, to not confuse the register scavenger -function prologue and epilogue are not emitted, if the stack size is 16. 16 means it is empty - there is only the
