[LLVMdev] 2.4 Pre-release (v2)

[Ben Swire]

Hi, I've just tried out version 2.4, and it doesn't work for me in
situations where 2.3 seems fine. The current trunk code appears to have
the same problem.

When I compile a simple program in llvm-gcc, I get a .bc file as output
as expected. When running lli or llc on this file, however, I get
various errors and an assert, stopping the .s file from being created.


Example output of llc:

[bens at BenSCentOS llvm]$ llc hello.bc -o hello.s
Value still in symbol table! Type = 'i32' Name = 'tmp3.3'
Value still in symbol table! Type = 'i32' Name = 'tmp3.4'
Value still in symbol table! Type = 'i32' Name = 'tmp1'
Value still in symbol table! Type = 'i32' Name = 'tmp3'
Value still in symbol table! Type = 'i32' Name = 'tmp3.1'
Value still in symbol table! Type = 'i32' Name = 'tmp3.2'
llc: ValueSymbolTable.cpp:29:
llvm::ValueSymbolTable::~ValueSymbolTable(): Assertion `vmap.empty() &&
"Values remain in symbol table!"' failed.
llc[0x89482d6]
/lib/libc.so.6(abort+0x101)[0xc7a631]
/lib/libc.so.6(__assert_fail+0xfb)[0xc7216b]
llc[0x88e92ba]
Aborted

When I run lli, I get pretty much the same, except that the program's
expected output appears before all the errors (so I guess it is doing
some good in there, looks like something just isn't tidying itself up
afterwards).

Opening hello.bc as-is in an editor shows that there is some data in
there (about the same amount as I had when compiling with 2.3), but when
I run llvm-dis on it, it outputs blank.

I ran the llvm/configure file with the same options as I did for 2.3
(--enable-optimized, that's it)

I'm building with a Linux machine, 
CentOS 5
Dual core Pentium 4, 3.2GHz x 2
1GB RAM

Am I somehow getting something wrong, or is 2.4 broken? The problem
isn't with my test program, I've tried it with a few c files of varying
simplicity.

LLVMers,

The 2.4 pre-release (v2) is available for testing:
http://llvm.org/prereleases/2.4/

If you have time, I'd appreciate anyone who can help test the release.
Please do the following:

1) Download/compile llvm source, and either compile llvm-gcc source or
use
     llvm-gcc binary.
2) Run make check, send me the testrun.log
3) Run "make TEST=nightly report" and send me the report.nightly.txt
4) Please provide details on what platform you compiled LLVM on and how
     you built LLMV (src == obj, or src != obj)

Please COMPLETE ALL TESTING BY the end of the day on November 5th.

Thanks,
Tanya

P.S. PPC llvm-gcc binary will be up later today. Sorry for the delay.
