All of "no-frame-pointer-elim-non-leaf" "no-frame-pointer-elim-non-leaf"="true" "no-frame-pointer-elim-non-leaf"="false" mean "frame-pointer"="non-leaf", which is quite counter-intuitive. llvmorg-10-init-16046-ga36ddf0aa9d accidentally broke it. This fixes the -DLLVM_ENABLE_EXPENSIVE_CHECKS=On test: ``` *** Bad machine code: Non-flag-setting Thumb1 mov is v6-only *** - function: pass_C - basic block: %bb.0 entry (0x1fc9bf0) - instruction: $r0 = tMOVr killed $r6, 14, $noreg ```
