Hello List, Can anybody point me to a number-to-string formatting function? I need to convert, say, 12 to 00012. I tried format() but its too stubborn: it seems to only pad with spaces. Thank you, Your culpritNr1 -- View this message in context: http://www.nabble.com/Paddding-an-integer-with-zeros-tp20095300p20095300.html Sent from the R help mailing list archive at Nabble.com.

Hello, I'm new to LLVM and I'm using it to translate from LLVM to another language rather than emitting actual machine code. The target language has instructions that operate on pointers which aren't naturally exposed in LLVM. Here's what I've done to add pointer support for an instruction called PADD that takes a pointers and an offset and returns the new pointer value:

Hi Bill, Yes, there are other patterns. I tried commenting out all the other instructions definitions and I still get this error. After debugging TblGen I found that the second pattern is being generated as a variant of the first. I think the reason is that the PADD instruction is inheriting the commutative property from ADD defined inTargetSelectionDAG.td. The variant ends up being the same

Are there any other patterns in your TD file? If so, then one of the ones before this pattern will match everything, and this pattern will never be matched. -bw On Jul 3, 2009, at 8:27 PM, Javier Martinez wrote: > Hello, > > I'm new to LLVM and I'm using it to translate from LLVM to another > language rather than emitting actual machine code.

Consider the following function which doubles a <16 x i8> vector: define <16 x i8> @test(<16 x i8> %a) { %b = add <16 x i8> %a, %a ret <16 x i8> %b } If I compile it for x86 with llc like so: llc paddb.ll -filetype=asm -o=/dev/stdout I get a two-op function that just does paddb %xmm0 %xmm0 and then returns. llc does this regardless of the

Hi I have a problem with passing line and symbol parameters to user defined panel functions I had a look at the archives and created a panel function on what was shown and on panel.loess. I could not to get panel.locfit to work for what I intend it for. There is another layer to work with before success as lp() is called from locfit. xx <- structure(list(Farm = c("A",

Hi ilai Thank you for your suggestions. I do not know what happened yesterday I must have omitted a few changes out in going from R to email and apologies for the double posting - I had troubles sending it as my ISP gave a message of not being connected for email but was for the web I was trying to get panel.Locfit to work in a number of situations. 1. Conditioned by Farm (3 panels) with 2

That's kind of strange. It might be some type of "default". However, you probably don't want to turn off the "commutative" property, unless it really isn't commutative. I know it's painful, but it might be best just to slog through the TableGen code in a debugger, and see why it is that your stuff inherits properties from the ADD in

Hi all, The patches linked below introduce a new family of intrinsics, for integer saturation: @llvm.usat, and @llvm.ssat (unsigned/signed). Quoting the added documentation: %r = call i32 @llvm.ssat.i32(i32 %x, i32 %n) is equivalent to the expression min(max(x, -2^(n-1)), 2^(n-1)-1), itself implementable as the following IR: %min_sint_n = i32 ... ; the min. signed integer of

To add to the wish-list for "convolve": For modeling processes that decay exponentially in time, e.g., fluorescence, it is desirable to have a function that convolves an arbitrary vector with an exponential using an iterative method. In the TIMP package (which won't be on CRAN till R 2.5.0 is official, but is for now at www.nat.vu.nl/~kate/TIMP) we implemented this special-purpose

Typically, you get this from (a little overlapping) compression, DSP, or pixel-handling code. Off the top of my

I'm trying to understand the rational behind the arc4random() and arc4random_stir() functions in the OpenSSH source tree. On a system that has a good random number generator, say an in kernel /dev/random what extra functionality is this stuff providing ? Would it be acceptable to replace the calls to arc4random() with reading from /dev/random and drop the arc4random_stir() all together ?

Hi, Man page for 'convolve' says: conj: logical; if 'TRUE', take the complex _conjugate_ before back-transforming (default, and used for usual convolution). The complex conjugate of 'x', of 'y', of both? In fact it seems that it takes the complex conjugate of 'y' only which is OK but might be worth mentioning because (1) conj=TRUE is the

connecting legacy PBX to Asterisk (for the very same reason, those PBX use TE-PTMP). If others could join this thread and say if they agree or not with NT-PTMP being the 2nd most needed mode, would be great.

This patch adds a per-node bucket to the heap structure in Xen. During heap initialization the patch determines which bucket to place the memory. We reserve guard pages between node boundaries in the case that said boundary isn''t already guarded by the MAX_ORDER boundary to prevent the buddy allocator from merging pages between nodes. -- Ryan Harper Software Engineer; Linux Technology
