disassembling this bitcode is awfully slow
Recently I wanted to move from LLVM-2.6 to LLVM-2.7. I encountered that some
LLVM code I generated through the Haskell/C interface to LLVM takes ages to
arrive in a bitcode file. This problem did not exist in LLVM-2.6. Now I found
that also assembling and disassembling that bitcode file is very slow.
$ time llvm-dis -o generator000-dis.ll generator000.bc
real 1m56.906s
user 1m56.511s
sys 0m0.300s
$ time llvm-as generator000-dis.ll
real 2m1.090s
user 2m0.584s
sys 0m0.304s
