Ryan,
This looks like a bug. Could you file it, please?

[LLVMdev] bytecode reader assertion failure
I am still diagnosing the cause of the assertion failure and will submit
a bug when I better understand the problem.

[LLVMdev] opt -verify
I am writing an interprocedural compiler pass. Because the passneeds
information from a FunctionPass, e.g., the post-dominance frontier
(PDF), and because a ModulePass is not permitted to require a
FunctionPass, I am forced to make my pass a FunctionPass and do majority
of its work in the doFinalization() method.
When I run "opt -mypass -verify -o code2.bc code1.bc" I get no

[LLVMdev] opt -verify
I followed what you said and called verifyModule() with the
AbortProcessAction option. verifyModule() returns false, but does not
abort and does not print out any information about what caused the
verification to fail.

I also tried iterating through the functions of the module and calling
verifyFunction(), which also returns false, but does not cause an abort
or report anything to stderr about what caused the verification to fail.
From the doxygen for verifyFunction() and verifyModule(), it seems
like they both should print information to stderr if the verification
fails and should abort opt if

I think I misread the doxygen. verifyFunction & verifyModule return
false if no errors are detected. However, my question now becomes why
does the code produced by my transform pass verification, but it causes
an assertion failure in the byte reader when it (the code produced by my
transform) is passed to another invocation of opt?

[LLVMdev] Memory leaks in LLVM
Hi,
Probably some of the leaks Valgrind reports are spurious, but the numbers
seem to be significant enough to demand some attention:

BitcodeReader.cpp bug under LTO
Hi guys,
We have found a bug of BitcodeReader.cpp in processing an LTO bitcode file. As LLVM doesn't emit use-list for LTO bitcode files, many forward references will happen when BitcodeReader processes the bitcode file, and LLVM uses placeholders for those forward references and resolve them later.
When parseConstants() reads in a CST_CODE_CE_SELECT record, e.g.
select

BitcodeReader.cpp bug under LTO
Hi Eli,
Thanks for the advice! By delaying processing the "select" until we have resolved other records(like "aggregate " in this case) as you did for "shuffle", the test case passes now. But I wonder if it's an ultimate solution: what if the selector of a "select" is the output of another forward-reference "select" that hasn't been

Internal error in 'ls' for pathological environments (PR#14035)
nchar(with(list(2),ls())) gives an internal error. This is of course
a peculiar call (no names in the list), but the error is not caught
cleanly.
It is not clear from the documentation whether with(list(2)...) is
allowable; if it is not, it should presumably give an error. If it is, then
ls
shouldn't have problems with the resulting environment.

Select Helper Array of Array + Filter
Noob alert!
Hi, I am having trouble figuring out how to filter a select helper. The
following shows all of the rows in the table but I would like to filter
the collection from the list_name column (:list_name => "Project
Status"):
@project_status = Valuelist.all.collect {|s| [s.list_value,s.id]}
Thanks in advance, James

index and by groups statement
Dear R-users
Im working with a dataset that contains information
for 8 groups of data and I need to select a sample of
certain size (100 cubic feet by group) from this
database for each of these 8 groups. To clarify, here
is the starting code Im working with:
k<-nrow(dataset)
ix<-sort(runif(k),index.return=TRUE)$ix

Should this go into 4.2.0 or be held for 4.2.1 (or is it not 4.2.x
material at all) ?

[LLVMdev] Bytecode Format Manual
Dear All,
Would somebody be able to update the Bytecode Format Manual with the 28
bit bytecode version numbers for LLVM 1.4, 1.5, and 1.6 (or point me to
the file which defines it so I can look it up)?
Thanks.

[LLVMdev] [patch] Writing ConstantUnions
Hello,
I noticed a bit of a gap in the current code for unions: a
ConstantUnion cannot be written out to .ll.
Hopefully I'm not stepping on Talin's toes by posting this, it's a
fairly straightforward adaptation of the code for structs just above.
Tim.

index columns in postgres

working some things out internally so it seems to me that indexing
frequently searched table fields might be useful.
I am using postgres and via postgres, I have added an index to one of my
tables whose index is the same name as the column name. The ''find''

Huge VQ codebooks
Hi,
Does anybody know how codebooks are generated in OggVorbis encoder? We
are porting oggorbis encoder on embedded platform for which VQ codebook
memory is hugeeee to imagine. How can we reduce that? Can we do VQ with
less codebooks and if yes how? If any help available?
