[LLVMdev] Debug Info Documentation State
Thanks for the quick reply! I will keep the DIBuilder and Clang's
CGDebugInfo as my reference for now.
At the moment I want to stick with generating .ll -- it's somewhat easier
for me to debug the output of my compiler that way, and I haven't
programmed much in C/C++ for years -- mostly been a JVM guy. But at one
point I may want to look into bindings or even creating a bootstrapped

[LLVMdev] Optimize away sqrt in simple cases?
That's a pretty seriously unsafe floating point optimization. It could be done in fast-math mode, but I doubt we currently do it.

[LLVMdev] Optimize away sqrt in simple cases?
hi!
I'm using LLVM 3.2. Does it optimize away llvm.pow(llvm.sqrt(x), 2) to `x`
with any settings? I tried with llc -O3, but that didn't do it.
Would be nice to write |v|² in my language ('v' being a 2D vector say and
|...| and ...² being two separate infix "operators") -- when I could
compare squares of lengths as well as lengths, and know that the sqrt is
optimized

[LLVMdev] Debug Info Documentation State
Hi,
I wanted to add debug info to my language (compiler written in Scala,
outputs .ll files), but I found it really hard to do based on the
documentation provided at http://llvm.org/docs/SourceLevelDebugging.html (I
looked at the specific doc for LLVM 3.0 though)
With LLVM 3.0, DI version 8 (which is documented there) seemed to work,
except DW_TAG_auto_variable for which I used version tag 11

[LLVMdev] Is using lots of in-register values in IR bad?
Hi,
I'm a newbie when it comes to compilers (and even close-to-machine coding),
but recently started working on my own language and am using LLVM as the
mid/backend. Currently I'm generating .ll files from a front-end written in
Scala. The language is not really serious, just a way to learn more about
compilers (and LLVM) and maybe serve as a base for further experiments. It's

I just saw this thread and wonder why it's "seriously" unsafe? I see only one
problematic corner case.
For x >= 0.0 the result cannot lose precision.
For x = NaN the

Sound skips in all games since Wine 1.1.6
In 1.1.5 the sound/music in games played allright. Since 1.1.6 it skips badly - plays for a couple of seconds, then stops for half a second, then plays again, then skips and so on. Happens on every game on Steam - Team Fortress 2, Everyday Shooter, Peggle Extreme - and also without Steam - Icy Tower.
I have Razer Barracuda AC-1 sound card. I've found that in Winecfg when I choose Alsa driver
