[LLVMdev] Exec time and compile time testing.
Stepan,
If you interested in only running a subset of the suite, then you can just cd to the associated subdirectory and execute the make command there. Due to the structuring of the makefile it's rather difficult to run an individual test. If you want to setup the structure of the test-suite (say after a fresh checkout/build) I've found that 'make -n' is helpful. It will allow

[LLVMdev] make check-lit + grep escape characters
I just want to update test/Transforms/LowerSwitch/feature.ll that
already uses grep.
It uses grep + count, probably due to shorter construction.

If you are touching such a test, please convert it to FileCheck. Use of
'grep' in tests is an endless source of problems, and we are

[LLVMdev] Debug Info and MergeFunctions Transform
Hi David,
After merging we always remove body of "G" (function we want to merge with "existing" one).
In case with "writeThunk" we could add such info for "G", but it would be just a single string: reference to first string of "G".
Ideal way here, is to merge debug information itself, and provide "F" with information for "G"

[LLVMdev] How to force the creation of arrays with zeroes?
Hi Chris. There is no zero arrays created. Probably this patch is not optimal and I'll reworked it today. But the main idea is keep a single zero-item when ConstantAggregateZero was wrapped and return this zero item as result of getOperand call.
Note that wrapper has no parent classes, it has very local and short lifetime (method body), it exists outside the LLVMContext and needed for

[LLVMdev] [LLVM, llvm-mc, AsmParser] Symbol locations.
Now I see, that its to so trivial as I thought before. There are a lots of parser extensions that creates the symbols. And in each place we need insert add its location info. I also found that MCContext has several create symbols methods, but all these methods uses CreateSymbol private method.
So I see two possible ways here:
1. To aggregate all GetOrCreate-like symbol methods inside the

[LLVMdev] [LLVM, llvm-mc, AsmParser] Symbol locations.
Hi everybody. I found that there are some problems with symbol location in AsmParser.
1. We need to know where symbol was declared.
2. We need to know where symbol was defined first time.
There are two ways:
1. Add helper table to the parser with additional symbol info. But it takes additional memory consumption.
2. Add user tag (void*) for MCSymbol object. As I understood MCSymbol can live

[LLVMdev] MergeFunctions: reduce complexity to O(log(N))
Hi Stepan,
This looks interesting! Some high-level comments:
- Please post the patch untarred next time. Also, I'm not sure if it's typical
to provide supporting documents in .doc format; while many of us probably
have access to Word, a more portable and email-friendly format (like text,
markdown or rst) is probably better.
- Have you profiled this? What's the speedup? I

[LLVMdev] [LLVM] make check-lit never finished...
Hi. I just want to know does anyone has the same problem or not.
After running "make check-lit" tests are stopped at 61th percent (Linker tests). Each time it stops on different tests.
Thanks.

[LLVMdev] MergeFunctions: reduce complexity to O(log(N))
Hi all,
Previous patch has been split onto series of small changes.
On each stage (after each patch) MergeFunctions pass is compilable and
stable.
Please find patches in attachment for review.
To apply all patches at once, use "apply-patches.sh" script as follows:

1. cd <llvm-sources-dir>

Hm... tests were corrected themselves. No svn updates was made.

Eclipse doesn't want to debug it too. It crashes at the start of debug session.
I reboot my computer again, and all work well now. Probably some specific bios + OS + (specific cpu

[LLVMdev] How to force the creation of arrays with zeroes?
How many times will a typical client call getOperand on your helper when it wraps a 10,000 element ConstantAggregateZero?
With CAZ the client is force to think about this case, and often handles it much much more efficiently. CAZ is a time optimization as well as a space optimization.

[LLVMdev] MergeFunctions: reduce complexity to O(log(N))
Hi all,
I propose simple improvement for MergeFunctions pass, that reduced its
complexity from O(N^2) to O(log(N)), where N is number of functions in
module.
The idea, is to replace the result of comparison from "bool" to
"-1,0,1". In another words: define order relation on functions set.
To be sure, that functions could be comparable that way, we have to
prove that order

[LLVMdev] Two questions about MergeFunctions pass
Hi Nick.
Can you help me sort some things out in MergeFucntions pass. While I was
working on MergeFunctions pass I got several questions. I hardly tried
to find all the answers by myself, but there are still two questions
without answer.
It is about merging functions itself (not comparing).
First question is:
Why sometimes we use RAUW and sometimes replaceDirectCallers. Would you
