C Library Stack Usage: AC6 vs AC5

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...

dear ARM, We recently update AC5 to AC6. When using AC6, the size of output file (.a and .bin) are very diffent from AC5. Our compile option is: --target=arm-arm-none-eabi -mcpu=cortex-r5 -O1 -fshort...
A delay() is dead in AC6, but OK in AC5, help!

Hi guys: here is my code ,it works in AC5, but when I change to AC6, it is dead in delay_1ms(), I have no idea why it happened: struct bsl_data_t{ uint32_t tick_1ms; }; static struct bsl_data_t g_bsl;...
