Noticed particularly the stack usage difference of a function _printf_f between ARM Compiler 6 (tested with 6.11) and ARMCC 5.06 (update 6) is a whopping 6x more on the AC6 (1968 bytes on AC6 vs 320 bytes on AC5), as reported by the linker static analysis.
Any reason why AC6 uses more stack in this case?
Appreciate any thoughts on this.

Two facts speak against the validaty of that judgement: you have demonstrated a lack of qualification to make such a broad statement, and you felt you had to make into a months-old, solved, thread that has nothing to do with that judgement.
