Hi, SystemZ supports @llvm.ctlz.i64() natively with a single instruction (FLOGR), and lesser bitwidth versions of the intrinsic are promoted to i64. For some reason, this leads to unfolded additions of constants as shown below: This function: define i16 @fun(i16 %arg) {   %1 = tail call i16 @llvm.ctlz.i16(i16 %arg, i1 false)   ret i16 %1 } ,gives this optimized DAG as input to instruction

Hi, I wished to shape the traffic that cross my ppp0 interface so I asked around and google''d a bit and I headed in the LARTC HOWTO. As stated in the early in the text, as the title implies, that is an "Advanced" HOWTO and while by no means rocket science, some prior knowledge is assumed. Unfortunately I found myself lost very soon and I''m writing here in hope

I have updated the klibc patchset based on feedback received. In particular, the patchset has been reorganized so as not to break git-bisect. Additionally, this updates the patch base to 2.6.17-git12 (d38b69689c349f35502b92e20dafb30c62d49d63) and klibc 1.4.8; the main difference on the klibc side is removal of obsolete code. This is also available as a git tree at:

Hi, I want to compile speex for use with my symbian mobile application. I am unable to find a step by step guide to complete this compile. I have found 2-3 posts on the mailing lists that talk about problems related to compiling for the symbian platform. I tried the fixes suggested but I am still confused. Do I need to modify/add any source files? Please provide a step by step guide.
