Allows building with Clang with "make COMPILER=clang [other flags...]".
The clang command has to be in the $PATH, as well as the associated
tools (clang-cpp, ld.lld, llvm-ar, llvm-nm, llvm-objcopy and
llvm-readelf).
Tested with Clang built from the master branch of [1] (development
version for 9.0):
mkdir build; cd build
cmake -G Ninja -DCMAKE_BUILD_TYPE=Release \
-DCMAKE_INSTALL_PREFIX=~/llvm-install \
-DLLVM_ENABLE_PROJECTS="clang;lld" \
-DLLVM_TARGETS_TO_BUILD="AArch64;ARM" \
~/llvm-project/llvm
ninja && ninja install
Limitations:
- CFG_CORE_SANITIZE_KADDRESS=y is not supported.
- CFG_WITH_PAGER is supported, but requires that the TEE core be
linked with the GNU linker. The reason is documented in
mk/clang.mk.
Bug:
- ldelf assertion failure in xtest 1019 when CFG_ULIBS_SHARED=y (QEMU)
E/LD: assertion 'maps[map_idx].sz == sz' failed at ldelf/ta_elf.c:1114 in ta_elf_print_mappings()
Prevents ldelf from displaying the TA mappings on abort or panic, but
does not seem to cause any other problem.
