possible compiler switches (* marks a currently required switch):
-----------------------------------------------------------------
GDB* support of the GNU Debugger
I386 generate a compiler for the Intel i386+
x86_64 generate a compiler for the AMD x86-64 architecture
M68K generate a compiler for the M68000
SPARC generate a compiler for SPARC
POWERPC generate a compiler for the PowerPC
VIS generate a compile for the VIS
DEBUG version with debug code is generated
EXTDEBUG some extra debug code is executed
SUPPORT_MMX only i386: releases the compiler switch
MMX which allows the compiler to generate
MMX instructions
EXTERN_MSG Don't compile the msgfiles in the compiler, always
use external messagefiles, default for TP
NOAG386INT no Intel Assembler output
NOAG386NSM no NASM output
NOAG386BIN leaves out the binary writer, default for TP
NORA386DIR No direct i386 assembler reader
TEST_GENERIC Test Generic version of code generator
(uses generic RTL calls)
-----------------------------------------------------------------
cpuflags The target processor has status flags (on by default)
cpufpemu The target compiler will also support emitting software
floating point operations
cpu64bit The target is a 64-bit processor
-----------------------------------------------------------------
Required switches for a i386 compiler be compiled by Free Pascal Compiler:
