[LLVMdev] ARM: unresolvable R_ARM_PLT32 relocation

[Karel Gardas]

Hello,

while working on GHC/ARM port using LLVM I'm attempting to compile GHC 
with shared libraries support. Thanks to LLVM backend this should be 
nearly done except few hacks here and there for ARM platform (inside GHC 
source code).

Everything kind of works, stage1 compiler is happily compiling haskell 
shared libraries and also stage2 compiler. The problem is while linking 
together stage2 compiler shared library. The linker complains about 
unresolvable R_ARM_PLT32 relocation, exactly this way:

/usr/bin/ld: 
compiler/stage2/build/SPARC/CodeGen/Gen32.dyn_o(.text+0x356c): 
unresolvable R_ARM_PLT32 relocation against symbol 
`integerzmgmp_GHCziIntegerziType_ltInteger_info'

All code is compiled with llc's -mattr=v7,vfp3 options. My question is 
if for example -code-model=large llc's option might help in this case or 
not. If the option will not help, then is there any other option or way 
which may help with this?

I'm asking since usually response time on this list is very quick 
especially in comparison with ARM build of GHC which takes hours and 
hours otherwise I would just give that a try...

Thanks a lot!
Karel
