...9;s extremely expensive to copy registers > in the particular register class. Evan, I am not sure what you mean by "if you just want a check" - I was trying to point out that for example the following very simple testcase makes llc -march=x86 -pre-RA-sched=list-td crash : define i32 @cctest(i32 %a, i32 %b) nounwind readnone { entry: %not. = icmp sge i32 %a, %b ; <i1> [#uses=1] %.0 = zext i1 %not. to i32 ; <i32> [#uses=1] ret i32 %.0 } The assert() which triggers has been introduced since llvm 2.4. So I assume that (at least...

The best fix is to teach this scheduler how to deal with these dependencies. :-) If you just want a check, I think it's easier to just check register class's copy cost. -1 means it's extremely expensive to copy registers in the particular register class.

Hi, I just switched to the 2.5 release branch and noticed that llc runs into the following assert in ScheduleDAGList::ScheduleNodeTopDown() using our custom backend: assert(!I->isAssignedRegDep() && "The list-td scheduler doesn't yet support physreg dependencies!"); It turns out that the register dependency concerns the condition code register which is

Hi all, When I ran the experiments to compare an application''s execution time in both a domU (named cctest1) and a native Linux machine (named ccn10), I noticed the application executes faster in domU. The host of the domU (named ccn9) and ccn10 are two nodes of a cluster and they have same hardware configurations. domU (cctest1) is created by exporting loopback files from dom0 on ccn9 as VBD backen...

Hi Quentin, My only remaining concern is around ABI compatibility. The following commit seems to indicate that in the previous round of evaluation, we didn’t find an existing ABI compatibility issue: http://llvm.org/viewvc/llvm-project?view=revision&revision=311388. I haven’t looked into the details of this issue - so maybe I’m worried over nothing? I’m wondering if since then on your side
