Hello All, I'm using gcc 5.4.0 for armhf target. I was compiling simple stack over flow test code with '-mapcs-stack-check' option. # gcc -mapcs-stack-check test.c test.c:1:0: warning: -mapcs-stack-check incompatible with -mno-apcs-frame #include<stdio.h> ^ As per my understanding from the above warning is -mapcs-stack-check option depends on -mapcs-frame. Is my understanding correct?? If yes, gcc should work for -mapcs-frame. But I found this in GCC online docs( https://gcc.gnu.org/onlinedocs/gcc-5.4.0/gcc.pdf) -mapcs-frame Generate a stack frame that is compliant with the ARM Procedure Call Standard for all functions, even if this is not strictly necessary for correct execution of the code. Specifying '-fomit-frame-pointer' with this option causes the stack frames not to be generated for leaf functions. The default is '-mno-apcs-frame'. This option is deprecated. Document saying '-mapcs-frame' option is deprecated. Does it mean I can't use -mapcs-stack-check option? Thanks in advance, Best Regards -Akhilesh
