At the last step of building llvm for arm target, I am unable to build llvm-gcc.
I am trying the follwing options:
$ ../llvm-gcc/configure --target=arm-linux --enable-pic --program-prefix=llvm-
--prefix=/llvm/install --disable-multilib --disable-optimized --enable-bindings
=none --enable-llvm=$PWD/../llvm-2.8 --enable-languages=c,c++ --disable-bootstr
ap
Then I get the following error when I run make:
$ make
../../llvm-gcc/gcc/config/arm/lib1funcs.asm:93:2: error: #error Unable to determ
ine architecture.
make[3]: *** [libgcc/./_udivsi3_s.o] Error 1
make[3]: Leaving directory `/llvm/arm_objects/gcc'
make[2]: *** [libgcc.a] Error 2
make[2]: Leaving directory `/llvm/arm_objects/gcc'
make[1]: *** [all-gcc] Error 2
make[1]: Leaving directory `/llvm/arm_objects'
make: *** [all] Error 2
I also tried the following configuration:
$ ../llvm-gcc/configure --target=arm-linux --enable-pic --program-prefix=llvm-
--prefix=/llvm/install --disable-multilib --disable-optimized --enable-bindings
=none --enable-llvm=$PWD/../llvm-2.8 --enable-languages=c,c++ --disable-bootstr
ap --with-arch=armv5te
Then I get the following error when I run make:
$ make

It looks like llvm/tools/lto wasn't built in step 1 (you can check to see if
this is so). From the Makefile, it will built tools/lto when ENABLE_PIC is 1.
Check to see what ENABLE_PIC is set to in the Makefile.config file. If it's
not set, try using the --enable-pic flag during LLVM's configure.
