llvm-lua 1.3.0 fails to compile to native machine code #10

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. lua-compiler hello.lua

What is the expected output? What do you see instead?

$ lua-compiler hello.lua 
/usr/bin/lua-compiler: line 5: realpath: command not found
dirname: missing operand
Try `dirname --help' for more information.
/usr/bin/llvm-luac -O3 -s -bc -o hello.bc hello.lua
Two passes with the same argument (-preverify) attempted to be registered!
UNREACHABLE executed!
/usr/bin/lua-compiler: line 40: 28376 Aborted                 $CMD "$@"
llvm-luac: failed to compile Lua code into LLVM bitcode.

What version of the product are you using? On what operating system?

LLVM-lua 1.3.0, LLVM 2.8, Slackware 13.1

You need to install the 'realpath' command.

What about that ?

I don't know why you would be getting that message and I can't reproduce that 
error.  The only thing I can think of is that something is wrong with how LLVM 
& llvm-lua are linked together, or there is a bad/broken pass compiled into 
LLVM.  Try running clang to see if it has the same error.

clang works fine, been compiling stuff with it without any problems. This 
problem didn't occur with LLVM 2.7 and llvm-lua 1.2.0.

Please attach the output from:
cmake .
and from:
make clean ; make VERBOSE=1

Based on the description of this LLVM bug:
http://llvm.org/bugs/show_bug.cgi?id=6801
it seems that a pass is link into twice.

Hi,

Sorry for the delay. Here are the logs of the output.

It looks like you have LLVM 2.8rc (release candicate installed) and not the 
offical 2.8 release.

But the real problem is that llvm-luac is being statically & dynamically linked 
to LLVM.
llvm-luac shouldn't be dynamically linked to:
/usr/lib/libLLVM-2.8rc.so

The last line of the cmake.log shows that .so file.  CMake gets that info from 
this command:
llvm-config --libs all

If you run that command you should see the .so file at the end.  It is wrong 
for llvm-config to be returning those static & dynamic libs together.

Attached is the output I get from that command.
