fixes:
test/CodeGen/Generic/vector-constantexpr.ll

test/CodeGen/CBackend/2004-02-15-PreexistingExternals.llx
just needed to have an intrinsic manually upgraded.

I have resolved 16 of the regressions for this bug. For the remainder, I need a
little help. Either I don't understand what the test is trying to do or it looks
like there's an actual bug in some part of LLVM I'm not familiar with.

The remaining tests are:

-Chris

Fixing the llvm-upgrade problem for test/CodeGen/Generic/vector-constantexpr.ll
was only half the story. llc also failed in getIntrinsicID because the function
has no name. This patch fixes it:

http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20070416/047738.html

I fixed an Alpha feature option bug. The list is down to:

I fixed all the X86 test cases. The list is now down to:

FAIL: /proj/llvm/llvm-2/test/CodeGen/ARM/hello.ll: exit(1) at line 3

Fixed CodeGen/ARM/hello.ll and align.ll.

Devang,

Many of those problems I've already fixed. Please update, rerun and post again.
The ones that remain are the CFE ones.

Reid.

After my last round of changes (to get rid of &&), add two more:

test/CFrontend/2006-09-25-DebugFilename.c.tr
test/Transforms/PredicateSimplifier/2006-10-22-IntOr.ll

Removed CodeGen/X86/sse-load-ret.ll xfail.

test/CFrontend/2006-09-25-DebugFilename.c.tr
anton fixed this

test/Transforms/PredicateSimplifier/2006-10-22-IntOr.ll
I fixed this.

I also fixed several others. Dejagnu is now finally clean for me. Should we close this?

-Chris

Let me just verify it here and if its clean I'll close.

Andrew,

There is only one regression remaining in this PR. It is:
test/CodeGen/Alpha/cmov.ll

The RUN: lines are:

; RUN: llvm-upgrade < %s | llvm-as | llc -march=alpha | not grep cmovlt
; RUN: llvm-upgrade < %s | llvm-as | llc -march=alpha | grep cmoveq

so no cmovlt instructions should be found. However, they are. The assembly
output is below. Please correct this test case/code gen at your earliest
convenience. When you do, please un-XFAIL the test case.

Thanks, Reid.

Alpha Assembly output:
