Bare metal cross compilers input

$

What are the input limitations of a bare metal cross compiler...as in does it not compile programs with pointers or mallocs......or anything that would require more than the underlying hardware....also how can 1 find these limitations..

I also wanted to ask...I built a cross compiler for target mips..i need to create a mips executable using this cross compiler...but i am not able to find where the executable is...as in there is 1 executable which i found mipsel-linux-cpp which is supposed to compile,assemble and link and then produce a.out but it is not doing so...

However the ./cc1 gives a mips assembly.......

There is an install folder which has a gcc executable which uses i386 assembly and then gives an exe...i dont understand how can the gcc exe give i386 and not mips assembly when i have specified target as mips....

please help im really not able to understand what is happ...

I followed the foll steps..1. Installed binutils 2.192. configured gcc for mips..(g++,core)
