Yes it is a list of strings.  But the first string
"/Users/joan/LLVM-9/llvm-project/build/Debug/bin/clang"
is a command.  The rest are arguments.  So you should set your debugger to
run this command:

"/Users/joan/LLVM-9/llvm-project/build/Debug/bin/clang"

with these arguments:

"-cc1" "-triple" "msp430" "-emit-llvm" "-disable-free" "-main-file-name"
"main.c" "-mrelocation-model" "static" "-mthread-model" "posix"
"-fmath-errno" "-masm-verbose" "-mconstructor-aliases" "-nostdsysteminc"
"-dwarf-column-info" "-debugger-tuning=gdb" "-target-linker-version" "305"
"-momit-leaf-frame-pointer" "-coverage-notes-file"
"/Users/joan/Documents-Local/Relay/RelayNou/main.gcno" "-resource-dir"
"/Users/joan/LLVM-9/llvm-project/build/Debug/lib/clang/9.0.1"
"-internal-isystem"
"/Users/joan/LLVM-9/llvm-project/build/Debug/bin/../msp430/include"
"-Oz" "-fdebug-compilation-dir" "/Users/joan/Documents-Local/Relay/RelayNou"
"-ferror-limit" "19" "-fmessage-length" "224" "-fobjc-runtime=gcc"
"-fdiagnostics-show-option" "-fcolor-diagnostics" "-vectorize-slp"
"-faddrsig" "-o" "main.ll" "-x" "c" "main.c"

Does that make sense?
