Hi Björn and Daniel, FoldPHIArgOpIntoPHI() is for unary ops (casts), but it calls FoldPHIArgBinOpIntoPHI() for binops which takes care of almost everything else? My minimal patch idea is to ease the restriction in ShouldChangeType because i1 is special. I tried the patch below, and it works on the example...and nothing in 'make check' failed. :) Index:

Hi, AFAICT there are two places where zext instructions may get folded into PHI nodes. One is FoldPHIArgZextsIntoPHI and the other is the more generic FoldPHIArgOpIntoPHI. Now, the former only handles PHIs with more than 2 incoming values, while the latter only handles casts where the source type is legal. This means that for an PHI node with two incoming i8 values, both resulting from `zext i1

Hi Sanjay, unfortunately that patch does not help in my case. Here's the IR that fails to get fully optimized: target datalayout = "e-m:e-i64:64-f80:128-n8:16:32:64-S128" target triple = "x86_64-unknown-linux-gnu" define fastcc zeroext i1 @testfunc(i8** noalias nocapture readonly dereferenceable(8)) unnamed_addr { entry-block: %1 = load i8*, i8**

Hello, I'm trying to install CentOS 6.0 64bit on a HP ProLiant ML110 G7 with a HP Smart Array B110i SATA RAID Controller. One logical drive (RAID 1+0) on the RAID Controller is already build. CentOS Installation can't find the logical Drive, but it shows me the zwo physical drives (sda+sdb). After searching the web, I found following hints: http://www.linuxquestions.org/questions/linux-hardware-18/raid-array-not-detected-new-hp-ml150g6-server-739130/ http://linuximagination.blogspot.com/2011/04/centos-installer-wasnt-detecting-sata.html OK.
