Can you give an example of instruction set of the mpu? Does it look like:
ADD, JMP, etc? If yes, then ADD need to be translated too unless if it inserted directly as 110010 101001 (ADD #), something like that....

Ok assume, we wrote the code from the keyboard in binaries, so kept writing such as 101001 110110 10110100, refers to ADD AX, etc. Can my machine just grab this binaries without the help of any compiler?

I guess the only way to fully understand it, i have to take hardware, and compiler construction courses.

Anyway, I appreciate all of your help members! Well Said, Well Answered

C compiler to build Sparc/Solaris binaries on Linux

Just that the Subject says. I am looking for a C compiler for Linux x86 that will allow me to compile a C source code file and the resulting binary will be able to run on a Sparc running Solaris. Thanks. (2 Replies)

NAME

       sfc - The SyFi Form Compiler

SYNOPSIS

       sfc [OPTIONS] input.form ...

DESCRIPTION

       The  SyFi  Form Compiler (SFC) is a form compiler from the FEniCS project, compiling variational forms from the Unified Form Language (UFL)
       to efficient C++ implementations of Unified Form-assembly Code (UFC).  SFC uses symbolic expressions for finite elements from SyFi.

OPTIONS

       -h, --help
	      Display help text and exit.

       -o DIRECTORY, --outputdir DIRECTORY
	      Output directory.

       -p PREFIX, --prefix PREFIX
	      Prefix string.

       -O LEVEL
	      Compiler optimization level.

       -c CACHE, --cache CACHE
	      Use JIT compiler cache.

       -i METHOD, --integration-method METHOD
	      Specify integration method. METHOD may be either quadrature (default) or symbolic.

       -d ORDER, --integration-order ORDER
	      Specify integration order.

       -w, --dolfin-wrappers
	      Generate DOLFIN C++ wrapper code.

       -b, --benchmark
	      Run benchmark of element tensor computation.

       -s, --safemode
	      Use safe mode when generating (quadrature) code, writing complete integrand expressions unmodified.

       -g DEBUGLEVEL, --debug DEBUGLEVEL
	      Enable generation of debugging code.

       -t, --timing
	      Enable timing of code generation process.
