Hi Experts,

For Cortex R and M processors Linaro has recommended the GCC arm-none-eabi 4.9 whereas for A series processors it is recommending normal GCC eabi.

what is the key difference between the same ?

Hi all,

How about the GCC compiler support of ARM arch v8 has been given. Is it full fledged, with all the options provided by ARMCC or it needs to be updated yet in future. I mean support for armcc Vs gcc

g++  provides an option  -pg   which allows to write epilg and prolog for functions

Does gcc does not have  such  an option?
