We're migrating to LLVM 3.1 and trying to use the upstream FMA patterns. Why is VFMADDSD4 defined with vector types? Is this simply because the gcc intrinsic uses vector types? It's quite unnatural if you have a compiler that generates FMAs as opposed to requiring user intrinsics. -Dave

...atue of PCP? could us just use the PCP language with annotation? Hi all, PCP is only partially implemented: conversion out of PCP to Graphite is not implemented, but the existing code would definitely help anybody working in interfacing other tools with PCP. The main people to contact are "Sjodin, Jan" <Jan.Sjodin at amd.com> Sebastian Pop <sebpop at gmail.com> Work on PCP has stalled because Jan has left for another group. In the hort term, Tobias is right that the best way to interface tools is to use the scoplib format and library from Louis-Noel Pouchet (PoCC). In a...

Better be quick! I am adding FMA4 and XOP now, and if you contribute code before I do, you can spare yourself some XOP merging. - Jan ----- Original Message ----- > From: David A.

That is too bad. :(  You can always review the patches, and if you see something that can be done better let me know. - Jan ----- Original Message ----- > From: David A.

Together with Jan Sjodin (in copy of this email), we begin an implementation of the JIT with MC. The idea, suggested by Jan, is to develop a MCJIT in parallel of the current JIT and to keep the two implementations until (at least) the new MC one is mature enough. Currently code is kept on gitorious (http://gitorious.org/ll...
