Hello, I am new to LLVM and doing some experiment with 3.2 on Ada code. Can anyone help me on the following error message? Thanks, ZY LLVM ERROR: Cannot select: 0xa7a0bf0: f32 = truncate 0xa7a5ea8 [ID=24] 0xa7a5ea8: i32 = X86ISD::SHLD 0xa790280, 0xa790390, 0xa76e088 [ID=22] 0xa790280: i32,ch = load 0xa7386a0, 0xa7a68d8, 0xa7a5628<LD1[%1482+4], anyext from i8> [ID=19]

Duncan, Thanks for getting back to me. I am not sure how to find the original bitcode (and related Ada source code) that causes the truncate. This is the error message that gcc gave me when I tried to compile an Ada source file using dragonegg plugin (gcc -c -fplugin...). ZY ps, sorry for multiple emails, trying to find out how to reply to a thread in the mailing list On Sat, May 11, 2013 at

Duncan, Is there a way (switch) for embedding original source code in the generated .s file? thanks, ZY On Sun, May 12, 2013 at 4:12 AM, Duncan Sands <baldrick at free.fr> wrote: > Hi ZY, > > > On 11/05/13 22:21, Zhiyuan Ren wrote: > >> Duncan, >> >> here is part of the assembly around the problem area.

Duncan, here is part of the assembly around the problem area.

Hello, I am trying to call the BLAS Level1 function zdotc from R via a .C call like this: #include "R.h" #include "R_ext/BLAS.h" void testzdotc() { Rcomplex zx[3], zy[3], ret_val; zx[0].r = 1.0; zx[0].i = 0.0; zx[1].r = 2.0; zx[0].i = 0.0; zx[2].r = 3.0; zx[0].i = 0.0; zy[0].r = 1.0; zy[0].i = 0.0; zy[1].r = 2.0; zy[0].i = 0.0; zy[2].r = 3.0;

Hi all - We're running a 3-node distributed volume, using gluster 3.3.1. We're seeing a rare but repeated issue, where files are written to the volume, appears to be written OK, but are not accessible via NFS or the gluster client. These files appear when we inspect the bricks directly. For example, the path in question is

Hello Thanks for looking into this. I can't be very confident what the knock on result of a change like that would be, especially on architectures that are not Arm. What I can do though, is run some benchmarks and look at that results.

Dear R users, I'm trying to carry out monte carlo integration of a posterior density function which is the product of a normal and a gamma distribution. The problem I have is that the density function always returns 0. How can I solve this problem? Here is my code #generate data x1 <- runif(100, min = -10, max = 10) y <- 2 * x1^2 + rnorm(100) # # # # # # # # Model 0 # # # # # # #

Thanks for the perf testing. I assume that DAG legalization is equipped to handle these cases fairly well, or someone would've complained by now... FWIW (and at least some of this can be blamed on me), instcombine already does the narrowing transforms without checking shouldChangeType() for binops like and/or/xor/udiv. The justification was that narrower ops are always better for

Duncan, Is there a way to link or trace .s code to certain lines in the original source code?

If you want to get the original name by a library function, as Jonathan mentioned, you can call __cxa_demangle in cxxabi.h. However, this API is only available in gcc. If you want something more portable, try glog or libibert, notice libibert is GPL licensed.

Dear list, I used rqss() in quantreg package for a piecewise linear regression. Can someone tell me how to find the x values corresponding to the breakpoints and the slopes for the phases before and after the breakpoints? I searched the list and gather that there is another package "segmented" that does that, but my stat is pathetic, and I have difficulty setting the parameters right
