llvm dev - Jun 2008 - [LLVMdev] Compiling llvm libraries to run on iPhone

Hi,
 
I was wondering whether anyone has managed to compile the LLVM libraries to run
on iPhone?
 
After compiling and installing the iPhone toolchain on MacBook running Leopard
(10.5.2).  I run configure
In the llvm2.3 directory:
 
./configure –host=arm-apple-darwin –target=arm-apple-darwin –enable-optimized
–enable-targets=arm
 
I run make, including an override for TBLGEN (because I obviously can’t run the
native ARM tblgen):
 
make ENABLE_OPTIMIZED=1 TBLGEN=/usr/local/bin/tblgen
 
All goes very well until I get the following error:
 
llvm[3]: Compiling ScheduleDAGList.cpp for Release build 
llvm[3]: Compiling ScheduleDAGRRList.cpp for Release build 
llvm[3]: Compiling SelectionDAG.cpp for Release build 
llvm[3]: Compiling SelectionDAGISel.cpp for Release build 
/var/folders/Xq/XqzGACxLHWq4Af0cQbEMdE+++TI/-Tmp-//cc6xGQcn.s:unknown:immediate
value (-288) too large
make[3]: ***
[/Users/ur/llvm-2.3/lib/CodeGen/SelectionDAG/Release/SelectionDAGISel.o] Error 1
make[2]: *** [SelectionDAG/.makeall] Error 2
make[1]: *** [CodeGen/.makeall] Error 2
make: *** [all] Error 1
 
I have also tried compiling v2.2 and get the same error.
 
Any help would be really appreciated,
 
Rob.

Hmmm, you are definitely a brave soul :-)

Try
make ENABLE_OPTIMIZED=1 TBLGEN=/usr/local/bin/tblgen VERBOSE=1

and look what the command for compiling SelectionDAGISel.o is.
Then execute it directly, adding -S --save-temps etc. to the soup.

My theory is that the assembler freaks out on illegal input.
Try to find the corresponding snippet (of the .cpp file)
and reduce it to a minimum.

File a bug report (http://llvm.org/bugs/). I am sure Evan or someone
else will love to fix it :-)

Cheers,

That looks like an internal compiler error.  Use delta
(http://delta.tigris.org/) to reduce the issue if possible, then send
a bug-report to whoever distributes your ARM compiler. (For an iPhone,
I'm guessing that's Apple.)

As Eli said, this address is only to be used if you use llvm-gcc
for compiling. But the best bet is probably to use Apple's
bugreporter.

This is being caused by the assembler you are using not being very good. You
should switch to the odcctools-9.2-ld branch of the assembler (the one that I
actively maintain). That one is like Apple's SDK assembler (who's source
code is available on their website) with a bunch of custom hacks/additions. More
information about how to get the newer versions of the open source iPhone
toolchain are available on my website: http://www.saurik.com/id/4. You are going
to have a hard time cross compiling anything complex with the one you have
installed.

  Hi,

   

  I was wondering whether anyone has managed to compile the LLVM libraries to
run on iPhone?

   

  After compiling and installing the iPhone toolchain on MacBook running Leopard
(10.5.2).  I run configure

  In the llvm2.3 directory:

   

  ./configure –host=arm-apple-darwin –target=arm-apple-darwin –enable-optimized
–enable-targets=arm

   

  I run make, including an override for TBLGEN (because I obviously can’t run
the native ARM tblgen):

   

  make ENABLE_OPTIMIZED=1 TBLGEN=/usr/local/bin/tblgen

   

  All goes very well until I get the following error:

   

  llvm[3]: Compiling ScheduleDAGList.cpp for Release build 

  llvm[3]: Compiling ScheduleDAGRRList.cpp for Release build 

  llvm[3]: Compiling SelectionDAG.cpp for Release build 

  llvm[3]: Compiling SelectionDAGISel.cpp for Release build 

 
/var/folders/Xq/XqzGACxLHWq4Af0cQbEMdE+++TI/-Tmp-//cc6xGQcn.s:unknown:immediate

  make[3]: ***

  make[2]: *** [SelectionDAG/.makeall] Error 2

  make[1]: *** [CodeGen/.makeall] Error 2

  make: *** [all] Error 1

   

  I have also tried compiling v2.2 and get the same error.

   

  Any help would be really appreciated,

   

  Rob.
