[PATCH 0/2] selftests/nolibc: fix loongarch build with recent versions of clang

Posted by Thomas Weißschuh 1 week, 2 days ago

LLVM 21 switched to -mcmodel=medium for LoongArch64 compilations.
This code model uses R_LARCH_ECALL36 relocations which might not be
supported by GNU ld which the nolibc testsuite uses by default.
