Merge patch series "Fix AArch32 compilation with Clang"
Dmitrii Sharshakov <[email protected]> says:
I faced some minor compatibility issues when choosing Clang as the
cross-compiler for my target.
Please review these two fixes, aiming at enabling Clang-based builds
(still using GNU binutils) for 32-bit ARM targets.
Tested to fix build with (also run-tested on qemu arm and arm64 with clang):
make ARCH=arm HOSTCC=clang CROSS_COMPILE=arm-none-eabi- CC=clang imx6ulz_smm_m2b_defconfig
make ARCH=arm HOSTCC=clang CROSS_COMPILE=arm-none-eabi- CC=clang -j20
