Hi Tanya,

Attached are the nightly test results when run with llvm-gcc
(report.nightly.txt), and when run with clang (clang-report.nightly.txt).

Tests were run on x86-64, Debian unstable, Linux 2.6.33, gcc 4.4.3,
64-bit. I built srcdir == objdir, I have built llvm and clang myself,
and used the binaries for llvm-gcc.

1. llvm-gcc 2.7 vs 2.6
compared to my results from Aug 31 2009, ignoring CBE failures:

new JIT failures:
MultiSource/Applications/spiff/spiff
SingleSource/Regression/C/2004-03-15-IndirectGoto

2. llvm-gcc 2.7 vs clang 2.7
When comparing the 2.7 llvm-gcc and clang results I see these
differences (is llvm-gcc considered baseline for clang?):
ALL FAIL (pass in llvm-gcc):
MultiSource/Benchmarks/PAQ8p/paq8p
MultiSource/Benchmarks/tramp3d-v4/tramp3d-v4
MultiSource/Benchmarks/Prolangs-C/archie-client/archie
MultiSource/Benchmarks/Prolangs-C/cdecl/cdecl
SingleSource/Benchmarks/Misc-C++/bigfib
SingleSource/Regression/C++/EH/ConditionalExpr
SingleSource/Regression/C++/EH/ctor_dtor_count-2
SingleSource/Regression/C++/EH/function_try_block
SingleSource/Regression/C++/EH/simple_throw
SingleSource/UnitTests/2006-12-04-DynAllocAndRestore
SingleSource/UnitTests/Vector/SSE/sse.expandfft
SingleSource/UnitTests/Vector/SSE/sse.stepfft

JIT failures in clang, pass in llvm-gcc:
MultiSource/Applications/sqlite3/sqlite3
SingleSource/Regression/C++/ofstream_ctor

3. Some performance regressions GCC/LLC  (2.6 -> 2.7), but keep in mind
that I wasn't using GCC 4.4.3 as comparison for llvm 2.6!

MultiSource/Applications/hexxagon/hexxagon  1.22 -> 1.14
MultiSource/Applications/lua/lua  0.91 -> 0.84
MultiSource/Applications/obsequi/Obsequi  0.93 -> 0.86
MultiSource/Benchmarks/ASC_Sequoia/CrystalMk/CrystalMk  1.01 -> 0.91
MultiSource/Benchmarks/FreeBench/fourinarow/fourinarow     0.94 -> 0.75
MultiSource/Benchmarks/FreeBench/neural/neural   1.0 -> 0.9
MultiSource/Benchmarks/MiBench/telecomm-gsm/telecomm-gsm   1.06 -> 0.9
MultiSource/Benchmarks/Olden/treeadd/treeadd  11.44 -> 9.89
MultiSource/Benchmarks/Olden/tsp/tsp  1.14 -> 1.02
MultiSource/Benchmarks/Ptrdist/anagram/anagram 1.33 -> 1.23
SingleSource/Benchmarks/Dhrystone/dry  7.32 -> 5.16
SingleSource/Benchmarks/Dhrystone/fldry   8.02 -> 6.65
....

I'll have to write a script to compare the results, its boring and
inaccurate to do by hand.

Will go through the bugzilla tomorrow and see if I need to open new bugs
for this stuff.

Surely you meant tools/clang-2.7

FYI I pulled the following revisions for ClamAV's llvm on top of 2.7:
r98349
r98410
r98447
r98508
r99143
r99146
r99147
r99160
r99400

I don't know if any of these qualify as regression fixes for 2.7, I'll
leave it up to you to decide if you want to put them into 2.7 or not.

Best regards,
