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;

Duncan, here is part of the assembly around the problem area. I used gcc -S -flto to generate the .s file, llvm-as on the .s fiile will show error: invalid cast opcode for cast from 'i40' to 'float' %638 = trunc i40 %637 to float %633 = bitcast i8* %632 to float* %634 = bitcast float* %633 to i40* %635 = load i40* %634, align 1 %636 = shl i40 %635, 7 %637 = ashr i40

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

Example: define i8 @narrow_add(i8 %x, i8 %y) { %x32 = zext i8 %x to i32 %y32 = zext i8 %y to i32 %add = add nsw i32 %x32, %y32 %tr = trunc i32 %add to i8 ret i8 %tr } With no data-layout or with an x86 target where 8-bit integer is in the data-layout, we reduce to: $ ./opt -instcombine narrowadd.ll -S define i8 @narrow_add(i8 %x, i8 %y) { %add = add i8 %x, %y ret i8 %add } But on

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 # # # # # # #

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.

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

Hi, Can anyone explain me the differences in Q and R mode in Principal Component Analysis, as performed by prcomp and princom respectively. Regards L?vio Cipriano

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.

Hi, everyone! I'm new here trapped by a simple problem for days. When LLVM translates C++ source code to IR, it will add a prefix to the function name. For example: source code: int foo(){ return 1; } IR form: define i32 @_Z3foov() #0 { entry: ret i32 1, !dbg !20 } The getName() method returns _Z3foov, then how can I get foo? I know the debugging information is contained in
