That is perfectly reasonable and in fact  i have committed a hexagon change recently to that effect . The llvm flag hexagon-emi-lookup-tables controls the generation of lookup table for hexagon.
The problem is, I don't want the users of the compiler to use a combination of front end and back end flags to get the desired result.
"-fno-jump-tables -mllvm -hexagon-emit-lookup-tables=false". This could be much neater with a "-fno-jump-tables -fno-lookup-tables" or better just "-fno-switch-tables"
