Hi,
             In machine description macros the macro
NAME_MAIN and SYMBOL_MAIN have been
defined for arm in file unknown-elf.h gcc-2.95.3.
It is defined and given a name as __gccmain. When
compiling for arm-elf this function is getting called
after function prologue in the "main" function. Could
anyone tell me the cause of calling / not calling this
function.
-regards
