Hi All,

We recently migrated to llvm 9 from gcc -7 and found that the stack
usage is more  like 5K in the below function

getInfoFromDwarfSection() @ line : 1484

With our analysis and found that  "typename CFI_Parser<A>::PrologInfo
prolog" local data is taking up almost 4K space.
So we thinking to refactor the code by pushing the "prolog" to a global
Any comments on our approach will be appreciated

Thank you
