[LLVMdev] LLVM 2.9 64bits on Visual Studio 9
glei...@gmail.com
I have sucessfully compiled LLVM with CMAKE generator "Visual Studio 9 2008 Win64" (OS Windows 7).
-But when I run the Fibonacci example program in "release" mode, I get a crash with this visual studio popup message :
Microsoft Visual Studio C Runtime Library has detected a fatal error in Fibonacci.exe.
-Here is the visual studio output:
'Fibonacci.exe': Loaded 'C:\Users\IUC\Desktop\BUILD_64\bin\Release\Fibonacci.exe', Binary was not built with debug information.
'Fibonacci.exe': Loaded 'C:\Windows\System32\ntdll.dll'

It crashes after IR compilation when calling the JIT, the last program message is :
starting fibonacci(24) with JIT...
Please also note that it works fine in debug mode.
Seems to be a bug, but maybe I have missed something.. any idea would be really appreciated :)
Thanks!

E:\llvm\build\cmake-x64-vs10>bin\Release\Fibonacci.exe 24
verifying... OK
We just constructed this LLVM module:
---------
; ModuleID = 'test'
(snip)
---------
starting fibonacci(24) with JIT...
Result: 46368

Hi,
Thank you for your reply.
I did not try with VS2010, maybe the issue is only with VS2009 (and/or some
SP). As it works in Debug mode, at first sight I would say it is a project
configuration issue?
I have done some little debugging, and it seems to crash in the function
LiveVariable::runOnMachineFunction, on the call to VirtRegInfo[Reg].
In the assembly code, we can see the compiler first checks that the Reg
variable is in the range of the VirtRegInfo map, but it says no... although
a call to VirtRegInfo.inBounds(Reg) returns true!
Just as if the test in the assembly code was not done on the correct
value... so I try to add a volatile keyword on the Reg variable declaration,
and then it works correctly (I have replaced all variable handling the
result of TargetRegisterInfo::index2VirtReg with a volatile variable)...
...but no idea why it is working with this change :/
