           Summary: Testsuite not setup for LLVM (and non-Apple Platforms)
           Product: Test Suite

          Platform: PC
        OS/Version: Linux
            Status: NEW

Created an attachment (id=2751)

Result of "make -i check" for 'llvm-gcc' 4.2.1

The Testsuite not setup for LLVM and non-Apple Platforms such as Debian Linux.

I obtained the Trunk for LLVM (and it's accompanying gcc 4.2.1) and found
various problems compiling it on Debian Lenny 5.0. There are too many
patches to create 'llvm-gcc' from FSF's gcc-4_2-branch (dated 20070719)
(both "APPLE LOCAL" and "LLVM LOCAL") that it will be difficult to
make a direct comparison between 'llvm-gcc' and (un-modified) 'gcc'.

It would be better to separate the LLVM and Apple patches from each
other so they can be applied to newer versions of FSF's gcc . Your
choice of 4.2.1 is really great as it is quite stable but you will
have a nightmare trying to "diff and patch" your changes to gcc 4.4 .


The biggest problem may be that when you run the Testsuite Mailer 
("../llvm-gcc-4.2_trunk/contrib/test_summary") it will send mail to 
the FSF's gcc mailing list at: gcc-testresults at gcc.gnu.org . That
may not be appreciated since your 'gcc' is 4.2.1 (too old) _and_
it is modified. Unless the LLVM people look there they will not
even see the Testsuite Results.

Along these same lines when your 'llvm-gcc' crashes it says to use 
http://developer.apple.com/bugreporter as the address to report
Bugs (instead of here at http://llvm.org/bugs/ ). Apple only
wants Bug Reports for it's _un-modified_ gcc for Apple's Operating
Systems (and not LLVM Bug Reports for Linux Platforms such as Debian).


I had little luck in getting Ada to compile and so I ommited it from the
"--enable-languages=" list (I did read: ../docs/GCCFEBuildInstrs.html ).

I am enclosing the Testsuite Results (from "make -i check"). Many of
the failures are due to "Testsuite Failures" and not problems with
'llvm-gcc' (mostly due to assuming that 'llvm-gcc' is to be executed
on a "*-*-Darwin" Platform).


Best of luck with your Project,
Rob
