These are the current x86 regressions on the 2.0 release branch (fails now but
not in 1.9):

SingleSource/UnitTests/Vector/build also failed in LLVM 1.9, due to Bug 1126

Quuxplusone commented 17 years ago 
Both flops & stepanov failed due to:

Running test: Output/oopack_v1p8.llc
make[1]: Entering directory
`/home/asl/tmp/llvm/llvm-test/SingleSource/CustomChecked'
make[1]: *** No rule to make target `check-one'.  Stop.
make[1]: Leaving directory `/home/asl/tmp/llvm/llvm-
test/SingleSource/CustomChecked'

And so on.

lli also failed due to:

make[1]: Leaving directory `/home/asl/tmp/llvm/llvm-
test/SingleSource/CustomChecked'
dirname: extra operand `-force-interpreter=false'
/home/asl/proj/llvm/src/test/TestRunner.sh: line 15: test: ==: unary operator
expected
make: unknown keyword `--disable-core-files'
Quuxplusone commented 17 years ago 
Ok. I fixed my mistake and ignoring the CustomChecked, these are the only
remaining failures:

External/FPGrowth/fpgrowth - CBE
SPEC/CINT95/126.gcc/126.gcc - CBE
SPEC/CINT95/134.perl/134.perl- CBE
MultiSource/Applications/SPASS/SPASS - CBE
Quuxplusone commented 17 years ago 
ok, how do the cbe tests fail?  If GCC itself is crashing compiling the CBE
output, those are not-to-be-
fixed.

For SPASS I get undefined reference errors.

Okay, I filed Bug 1413 for that issue.  Please add a comment to it, mentioning
which gcc version you are
using.  I don't consider that issue to be a release blocker.

Quuxplusone commented 17 years ago

CBE regressions can't be fixed for this release (ie. gcc problems).
