what is a cross compiler
recently i was been to an interview to an automotive company, they have posed me a question that what section of compiler must be changed if the target is changed.
ie,if ur compiler is meant for generating executable to a 8051 target what changes do you do to make it flexible to generate the executable even to AVR, will you change the preprocessor,or the assembler or the linker or what....how will u proceed?

NAME
faucc - C compiler generating Intel code for 16 bit/32 bit CPUs.
SYNOPSIS
faucc [ -B path ] [ -D MACRO [=def]] [ -E ] [ -I path ] [ -L path ] [ -MD ] [-MF file ] [ -MP ] [ -MT target ] [ -O level ] [ -S ]
[ -T script ] [ -U macro ] [ -Wl,arg ] [ -Xlinker arg ] [ -b arch ] [ -c ] [ -f arg ] [ -m arch ] [ -nostdlib ] [ -o output ]
[ -print-lib-faucc-file-name ] [ --freestanding ] [ --no-stack-protector ] { file ...}
DESCRIPTION
faucc is a C compiler, that can generate Intel 16 bit or 32 bit Code.
OPTIONS
faucc tries to mimic the options of gcc. A number of options will be passed to the C preprocessor cpp or to the linker (done via a call to
the c-compiler gcc) in unmodified form.
-B path
Override the directory prefix where cc1 is looked up with path.
-D MACRO, -D MACRO=def
Define MACRO with the optional initial definition def. If def is omitted, it defaults to 1.
-E
Only perform preprocessing, but do not run the compiler.
-I path
Add path to the include path in which header files are searched.
-L path
Add path to the library search path, in which the linker will look for libraries.
-MD
Output dependency information while preprocessing.
-MF, file
Output dependency information while preprocessing to file.
-MP,
When the preprocessor should output dependency information, it will generate PHONY targets for each dependency.
-MT target
When the preprocessor should output dependency information, use target as the dependency rule target.
-O level
Currently ignored.
-S
Output assembly code.
-T script
Use script as linker script.
-U macro
Undefine a previously defined macro.
-Wl,arg, -Xlinker arg
Pass arg to the linker.
-b arch
Generate code for arch (either i286 or i386)
-c
Perform compilation, but do not link.
-f arg
Pass code generation argument arg to the compiler. See the cc1 man page for possible arguments.
-m arch
Currently ignored.
-nostdlib
With this option, the linker will only search for libraries that are passed as command line arguments.
-o file
Write output to file.
-print-libfaucc-file-name
Print the full path of the internal compiler library libfaucc.a.
-static
Perform static linking.
--freestanding, --no-stack-protector
Currently ignored.
EXAMPLES
faucc -c hello-world.c -o hello-world.o
Compile the program hello-world.c and output the object as hello-wolrd.o.
faucc -S -b i286 -o test.s test.c
Compile the program test.c to 16 bit code and output the assembly listing to test.s, but do not assemble or link the result yet.
