a) cpu64bitaddr, which means that we are generating a compiler which
will generate code for targets with a 64 bit address space/abi
b) cpu64bitalu, which means that we are generating a compiler which
will generate code for a cpu with support for 64 bit integer
operations (possibly running in a 32 bit address space, depending
on the cpu64bitaddr define)
All cpus which had cpu64bit set now have both the above defines set,
and none of the 32 bit cpus have cpu64bitalu set (and none will
compile with it currently)
+ pint and puint types, similar to aint/aword (not pword because that
that conflicts with pword=^word)
* several changes from aint/aword to pint/pword
* some changes of tcgsize2size[OS_INT] to sizeof(pint)

This directory contains the sources of the Free Pascal Compiler

|
|
If you want to compile/modify the compiler, please read first the
|
|
programmers manual.
|
|
|
|
To recompile the compiler, you can use the batch files :
|
|
+ mppc386.bat if you want to build a cross compiler from i386 to m68k
|
|
+ mppcsparc if you want to build a cross compiler from i386 to SPARC
|
|
|
|
or
|
|
Use the make utility as following
|
|
|
|
make OS_TARGET="compiler OS target" \
|
|
CPU_TARGET="compiler CPU target" \
|
|
FPCCPUOPT="Optimization level" \
|
|
PP="compiler used to compile FPC" \
|
|
COMPILER_OPTIONS="Options passed to compiler" \
|
|
|
|
|
|
If an option is omitted, then target CPU/OS will be same as current CPU/OS
|
|
|
|
Possibles targets are : linux go32v2 win32 os2 freebsd beos netbsd amiga
|
|
atari sunos qnx netware openbsd wdosx palmos macos macosx emx
|
|
|
|
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
|
|
cpu64bitaddr The targets use a 64-bit address space (pointers and
|
|
the default integer type are 64 bit)
|
|
cpu64bitalu The target cpu has 64-bit registers available (unless
|
|
cpu64bitaddr is also defined, pointers and default
|
|
integer type remain 32 bit, but the cpu can perform
|
|
64 bit calculations directly without needing helpers)
|
|
-----------------------------------------------------------------
|
|
|
|
Required switches for a i386 compiler be compiled by Free Pascal Compiler:
|
|
GDB;I386
|
|
|
|
to build a compiler to SPARC target using a Win32/i386 you just use :
|
|
make CPU_TARGET=SPARC
|
