[LLVMdev] Debugging using gdb
Hi John,
Yes, it was the problem of the namespace. Sorry for bugging for such a silly
mistake.
Thanks

[LLVMdev] problems with llvmgcc
Dear Prof. Adve,
Now I can use llvmgcc to compile a .c file into .bc file. But I still have
trouble simply run the .bc code. Below is the sequence I got when I tried.
I really don't know what's going on here. Please let me know how can I fix
it.
Thanks,

[LLVMdev] problems with llvmgcc
Dear llvm,
I just tried to compile a simple file hello.c. But each time I used
llvmgcc hello.c, it gave me the following error:
xli3|csil-suna33|~/cs426|[13]% llvmgcc hello.c
as: error opening '/var/tmp//ccapglpE.o': file exists!
Use -f command line argument to force output
I really got confused. Could you please let me know what's wrong?
thanks,

[LLVMdev] Live Intervals vs. Live Variables
LiveVariables gives you something like liveness analysis: where each
variable is alive, that is, across each basic blocks, where it is defined,
and where it is killed.
LiveIntervals gives you a linear representation of the variables as a set
of intervals. Yes, it handle holes in the live ranges. There is a very
nice description of these analysis and related data structures here:

[LLVMdev] problems with llvmgcc
The problem with llvmgcc invoking as instead of llvm-as has been fixed.
3 llvm-specific executables needed to be copied into a default location
where gcc can find them if it does not find them as configured (gcc was
configured for the paths on our research machines and copied over). Let
us know if you have additional problems.

If I read this correctly, it means that at each instruction there's a
list of live variables? I'm trying to figure out how to get at this

[LLVMdev] Error building compiler-rt
yes I think that is correct. I wrote a simple program to print if
sizeof(uintptr_t) != sizeof(unsigned char *) and when I compile with gcc
-m64 and execute it on a 64-bit host (that is different from the 32-bit
laptop on which I originally compiled the program), it says the sizes are
not equal.
Thanks

[LLVMdev] Error building compiler-rt
Dear Alexey,
Yes I am sure that the llvm, clang and compiler-rt are synced to the same
version. I downloaded them all from git
http://llvm.org/docs/GettingStarted.html#git-mirror
I think I need compiler-rt for my project but I'll verify it again to see
if I can proceed without it.
You are correct that compiler-rt is compiled with the just built clang. The

[LLVMdev] llvm-g++ barfs
Hi,
In the quest for better test cases for my MP, I thought of trying
the Stepanov Abstraction Penalty benchmark. But apparently llvm-g++
is not ready for such terrible things. Let me know if you want me
to send the source code (it is widely available).

Hi,
I am trying to build llvm along with clang and compiler-rt. When I run

llvm-3.2, which is what I need for my project, but also tried llvm-3.3 and
the current llvm source from the git repository).
