Test case .ll
I was experimenting with LLVM by hand writing .ll files. I was hacking with
arrays of SIMD vectors when I stumbled into a bug that causes LLI to segfault
but the code runs fine when I make a native executable.
$ llvm-as testcase.ll
$ lli testcase.bc
Stack dump:
0. Program arguments: ../oss/llvm/build/bin/lli testcase.bc
Segmentation fault
$ llvm-ld -native -o testcase testcase.bc
$Â ./testcase # runs fine
I also tried an older version of LLI, which did not segfault like the one from
LLVM trunk (r94421). The old, working lli version is:
Low Level Virtual Machine (http://llvm.org/):
llvm version 2.5 (Debian 2.5-0ubuntu1)
Optimized build with assertions.
Built Mar 6 2009(17:11:47).
