Hi,
GCC from ports can bootstrap libc++ and libc++abi, but on ARM it does
not work since the assembly cannot be parsed by our binutils. In a
clang world we use clang's integrated assembler. This means if we
use clang to compile it on ARM, it works.
I only set CXX to eg++ since I wanted it to be easily bootstrapable
for clang. Turns out that in the initial bootstrap of clang (of course)
it links to libestdc++. Only when we recompile clang with clang it will
start to use libc++ and libc++abi.
This means to bootstrap we:
- compile clang with eg++
- compile libcompiler_rt
- compile libcxx/libcxxabi with the newly built clang
- compile clang with clang
Thus I would like to set the default compiler for those two libraries
to clang, as once we bootstrapped clang, there will always be a clang
that can compile those two.
Comments?
