i'd like to know if there is any plan or existing work to add a Aho's trig language like code generator generator? "...If you are starting a new port, we recommend that you write the instruction selector using the SelectionDAG infrastructure." any other things i should know before i write one? thank you.

mdct.c, lines 436 onward (part of mdct_backward) state { DATA_TYPE *oX1=out+n2+n4; DATA_TYPE *oX2=out+n2+n4; DATA_TYPE *iX =out; T =init->trig+n2; do{ oX1-=4; oX1[3] = MULT_NORM (iX[0] * T[1] - iX[1] * T[0]); oX2[0] = -MULT_NORM (iX[0] * T[0] + iX[1] * T[1]); oX1[2] = MULT_NORM (iX[2] * T[3] - iX[3] * T[2]); oX2[1] =

As some of you know, I'm creating a hardware MDCT core. At the moment I'm working out the best way to create a lookup table for the trig values, as set up in mdct_init: /* trig lookups... */ for(i=0;i<n/4;i++){ T[i*2]=FLOAT_CONV(cos((M_PI/n)*(4*i))); T[i*2+1]=FLOAT_CONV(-sin((M_PI/n)*(4*i))); T[n2+i*2]=FLOAT_CONV(cos((M_PI/(2*n))*(2*i+1)));

Hello, I''m trying to compile Xen unstable on NetBSD, I''ve aplied the patches from http://cvsweb.netbsd.org/bsdweb.cgi/pkgsrc/sysutils/xentools41/patches/?only_with_tag=MAIN and copied the blk files from http://cvsweb.netbsd.org/bsdweb.cgi/pkgsrc/sysutils/xentools41/files/?only_with_tag=MAIN (I don''t know which of these patches have been applied to xen unstable, so

Hi all, I'm attempting to convert all the pointers to arrays the mdct_backward function so it can be partitioned off for a hardware implementation. Although this code is quite short I'm finding it a little tricky. As it stands, mdct_backward is passed values by reference i.e. void mdct_backward(mdct_lookup *init, DATA_TYPE *in, DATA_TYPE *out) o my modified version starts void

Hello All, I cant seem to do a trig regression in R. The equation is as follows : y = a+b*(sin((2*pi*x/360) - c))^2 a, b, c are coefs that I want. y, x are input vectors. The equation I put into R: lm(y ~ sin(2*pi*x/360)^2) This equation is missing the c and I dont get the right answer. Also, I dont know how to plot the lm over the x values instead of the indices. Any help is sincerely

The formatting of the IO-APIC debug key info has niggled me for a while, and with the latest interrupt bug I am chasing, has finally motivated me to fix it. The attached patch causes all columns to line up, and removes the comma which served no purpose in combination with the spaces already present. -- Andrew Cooper - Dom0 Kernel Engineer, Citrix XenServer T: +44 (0)1223 225 900,

We are slowly making the code generators more and more automatically generated as time goes on. The SelectionDAG infrastructure is mean to support exactly this (perform Tree or DAG pattern matching on the optimized DAG

Hi, I'm working on a project to generate native code for a domain specific langauge where the user defines functions in the complex plane. This implies that I need to support complex numbers as a datatype with LLVM. Its fairly straightforward to create a struct of two floats (or doubles, etc.) and do the simple operations like add, subtract, multiply, divide, etc. However, things get

R-helpers: I am using R 2.5 on Windows XP, packages all up to date. I have run into an issue with the MIcombine function of the mitools package that I hoped some of you might be able to help with.
