I did regenerate it but had to do some tweaking: Clang (build from
r72105) did refuse to compile MsgSendSmallInt.m with the commandline
from the makefile. I needed to modify it this way:
clang-cc -c -ftrapv -emit-llvm -fexceptions
-I/usr/lib/gcc/x86_64-linux-gnu/4.3.3/include MsgSendSmallInt.m -o
MsgSendSmallInt.bc
"-c" was needed because clang was trying to link the object file (which
failed), "-emit-llvm" because the "-emit-llvm-bc" switch was not
recognized and finally it kept complaining that it couldn't find the
objc/objc-api.h header, so I manually added the include path to my
gcc-version (Is this correct? I'm assuming LanguageKit is still
using the gnu-runtime and thus referred to the headers that came with
gcc's libobjc)
Unfortunately, all the tests still fail with SIGABRT reporting a failed
assertion deep within the innards of llvm:
edlc: TargetRegisterInfo.cpp:59: virtual const llvm::TargetRegisterClass*
llvm::TargetRegisterInfo::getPhysicalRegisterRegClass(unsigned int, llvm::MVT)
const: Assertion `BestRC && "Couldn't find the register class"' failed.
If have attached a backtrace. I hope it's of any use.
Cheers,
Niels
