|
||||||
|
.Sh NAME
|
||||||
|
.Nm cvmach
|
||||||
|
.Nd convert an executable file from ack.out to Mach-o
|
||||||
|
.Sh SYNOPSIS
|
||||||
|
.Cm ~em/lib/ack/cvmach
|
||||||
|
.Fl m Ns Ar number
|
||||||
|
.Oo
|
||||||
|

|
||||||

.Op Ar outfile
|

|
.Oc
|
||||||
|
.Sh DESCRIPTION
|
||||||
|
The
|
||||||
|
.Nm
|
||||||
|
utility converts an executable file from
|
||||||
|
.Xr ack.out 5
|
||||||
|
format to Mach-object format.
|
||||||
|
It can produce Mach-o executables for Mac OS X.
|
||||||
|
If the
|
||||||
|
.Ar infile
|
||||||
|
or
|
||||||
|
.Ar outfile
|
||||||
|
are not given, then
|
||||||
|
.Nm
|
||||||
|
reads from standard input or writes to standard output.
|
||||||
|
.Pp
|
||||||
|
The option is required:
|
||||||
|
.Bl -tag -width Ds
|
||||||
|
.It Fl m Ns Ar number
|
||||||
|
Sets the CPU type in the Mach header.
|
||||||
|
This must be
|
||||||
|
.Fl m Ns Cm 7
|
||||||
|
for Intel i386 or
|
||||||
|
.Fl m Ns Cm 18
|
||||||
|
for PowerPC.
|
||||||
|
.Nm
|
||||||
|
doesn't know how to make Mach-o files for other CPU types.
|
||||||
|
.El
|
||||||
|
.Pp
|
||||||
|
The input file must have four segments:
|
||||||
|
TEXT, ROM, DATA and BSS, in that order.
|
||||||
|
.Nm
|
||||||
|
converts them into four Mach sections in two Mach segments.
|
||||||
|
TEXT and ROM go in the RX segment (Read and eXecute).
|
||||||
|
DATA and BSS go in the RW segment (Read and Write).
|
||||||
|
.Nm
|
||||||
|
sets the page protection so programs can't write the RX segment,
|
||||||
|
and can't execute the RW segment.
|
||||||
|
The program will begin execution at the beginning of TEXT.
|
||||||
|
.Pp
|
||||||
|
.Nm
|
||||||
|
also converts the symbol table.
|
||||||
|
.Sh DIAGNOSTICS
|
||||||
|
.Bl -diag
|
||||||
|
.It text segment must have base 0x%lx, not 0x%lx
|
||||||
|
TEXT must begin immediately after the Mach header and load commands.
|
||||||
|
The message gives the correct
|
||||||
|
.Ar base .
|
||||||
|
Relinking the program with
|
||||||
|
.Cm em_led Fl b Ns 0: Ns Ar base
|
||||||
|
would fix it.
|
||||||
|
.It the %s segment must follow the %s segment.
|
||||||
|
TEXT and ROM must be continuous in memory, because
|
||||||
|
.Nm
|
||||||
|
maps them in the same Mach segment.
|
||||||
|
Likewise, DATA and BSS must be contiguous.
|
||||||
|
There may be a small gap between TEXT and ROM, or between DATA and
|
||||||
|
BSS, only if the gap is necessary to align ROM or BSS.
|
||||||
|
.It the data and rom segments are too close.
|
||||||
|
DATA and ROM must not share a page in memory, because
|
||||||
|
.Nm
|
||||||
|
maps them in different Mach segments, with different page protections.
|
||||||
|
The page size for i386 and PowerPC is 4096 or 0x1000 bytes.
|
||||||
|
For example, if ROM ends at address 0x2bed,
|
||||||
|
then DATA may not begin at 0x2bf0, because
|
||||||
|
.Nm
|
||||||
|
can't put the page from 0x2000 to 0x2fff in both Mach segments.
|
||||||
|
Relinking the program with
|
||||||
|
.Cm em_led Fl a Ns 2:4096
|
||||||
|
would fix it.
|
||||||
|
.It the bss space contains initialized data.
|
||||||
|
BSS must not contain initialized data, because
|
||||||
|
.Nm
|
||||||
|
converts it to a zero-fill section.
|
||||||
|
.El
|
||||||
|
.Sh CAVEATS
|
||||||
|
Mac OS X 10.4 for PowerPC does not protect pages against execution.
|
||||||
|
All mapped pages are executable, whether or not the execute bit is set
|
||||||
|
in the page protection.
|
||||||
|
.Nm
|
||||||
|
can't prevent the execution of the RW segment.
|
||||||
|
.Sh BUGS
|
||||||
|
The symbol conversion preserves the name and value of each symbol, but
|
||||||
|
may lose other information, such as the symbol type.

The osx386 platform
|
||||||
|
===================
|
||||||
|
|
||||||
|
ack -mosx386 ...
|
||||||
|
|
||||||
|
This platform produces Mach-o executables for Intel Mac OS X. These
|
||||||
|
are 32-bit executables using our i386 code generator.
|
||||||
|
|
||||||
|
See ../osxppc/README, because our osx386 platform has many of the same
|
||||||
|
limitations and bugs as our osxppc platform.
|
||||||
|
|
||||||
|
|
||||||
|
Bugs
|
||||||
|
----
|
||||||
|
|
||||||
|
Some programs can't read the tty after using job control to suspend
|
||||||
|
and resume the program (with ^Z and "fg" in bash). The read(2) system
|
||||||
|
call fails with EINTR. In ACK's stdio (in libc), the error is sticky,
|
||||||
|
so all reads fail. In Apple's stdio, the error is not sticky, and
|
||||||
|
only the next read fails. The EINTR seems to happen only on Intel Mac
|
||||||
|
OS X, and not on other platforms.

The osxppc platform
|
||||||
|
===================
|
||||||
|
|
||||||
|
ack -mosxppc ...
|
||||||
|
|
||||||
|
This platform produces Mach-o executables for PowerPC Mac OS X. You
|
||||||
|
can run them from the command line in the Terminal.
|
||||||
|
|
||||||
|
You *can't* link to libraries from other compilers. These static
|
||||||
|
executables don't use the dynamic linker. They don't load Apple's
|
||||||
|
libraries, so they can't call Carbon or Cocoa.
|
||||||
|
|
||||||
|
The executables use BSD system calls to interact with your Mac. Our
|
||||||
|
libsys provides only a few system calls, enough to run a few demo
|
||||||
|
programs, but not much else. Check the header files in ../osx/include
|
||||||
|
for the available system calls.
|
||||||
|
|
||||||
|
|
||||||
|
Bugs
|
||||||
|
----
|
||||||
|
|
||||||
|
ACK didn't run on Mac OS X when this platform was added. The only way
|
||||||
|
to run ack -mosxppc was as a cross compiler from another operating
|
||||||
|
system.
|
||||||
|
|
||||||
|
ACK doesn't have 64-bit integers, but Mac OS X uses 64-bit integers in
|
||||||
|
its system calls. Our libsys converts between 32-bit and 64-bit
|
||||||
|
integers by setting the high bits to zero, or discarding the high
|
||||||
|
bits. This affects lseek() and stat(). They report the wrong values
|
||||||
|
for file sizes and offsets beyond 4 gigabytes.
|
||||||
|
|
||||||
|
Our PowerPC code generator is new and probably has bugs. Its stack
|
||||||
|
layout and calling conventions are not compatible with other
|
||||||
|
compilers. It passes all function arguments on the stack, which is
|
||||||
|
slower than passing them in registers.
|
||||||
|
|
||||||
|
|
||||||
|
Example
|
||||||
|
-------
|
||||||
|
Compile something:
|
||||||
|
|
||||||
|
ack -mosxppc -O6 -o paranoia examples/paranoia.c
|
||||||
|
|
||||||
|
The executable has a symbol table. If you have Apple's Xcode, try
|
||||||
|
|
||||||
|
nm -g paranoia # to list the global symbols
|
||||||
|
otool -hl paranoia # to check the Mach header and load commands
|
||||||
|
gdb paranoia # to debug it
|
||||||
|
|
||||||
|
Within gdb, commands like "gdb main" and "gdb '.ret'" can disassemble
|
||||||
|
functions. Backtraces don't work, because our stack layout is not the
|
||||||
|
same as Apple's.
|
||||||
|
|
||||||
|
|
||||||
|
Other hints
|
||||||
|
-----------
|
||||||
|
|
||||||
|
PowerPC Macs became obsolete after Apple's transition to Intel. Mac
|
||||||
|
OS X 10.5 Leopard was the last version to run on PowerPC. The older
|
||||||
|
Mac OS X 10.4 Tiger was the last version to include Classic for
|
||||||
|
running Mac OS 9 programs. Our ack -mosxppc began to produce
|
||||||
|
executables in 2016, about 7 years after Apple released Mac OS X 10.6
|
||||||
|
Snow Leopard for Intel only.
|
||||||
|
|
||||||
|
Apple's Xcode included tools like gcc and gdb. It also had manual
|
||||||
|
pages for some system calls, like getdirentries(2). Some system calls
|
||||||
|
are like FreeBSD, some are unique to OS X. If you want to learn how
|
||||||
|
to call write(2) or sigaction(2), then a manual page from another BSD
|
||||||
|
or Linux might be enough.
|
||||||
|
|
||||||
|
Xcode 2.5 was the last version to run on Tiger. The "Xcode 2.5
|
||||||
|
Developer Tools" were a 902.9 MB download from Apple. As of 2016, the
|
||||||
|
download required an Apple ID and was available at:
|
||||||
|
|
||||||
|
https://developer.apple.com/download/more/
|
||||||
|
|
||||||
|
Older versions of Xcode came with Mac OS X. If your version of OS X
|
||||||
|
came with your Mac, /Applications/Installers might contain an Xcode
|
||||||
|
installer. If you upgraded OS X, your install DVD might have Xcode.
|
||||||
|
|
||||||
|
The source code at https://opensource.apple.com/ might reveal more
|
||||||
|
about system calls. For 10.4.11.ppc, the kernel is in xnu-792.24.17,
|
||||||
|
and Libc is in Libc-391.2.10. These files might help:
|
||||||
|
|
||||||
|
xnu*/bsd/kern/syscalls.master
|
||||||
|
master list of BSD system calls
|
||||||
|
xnu*/osfmk/kern/syscall_sw.c
|
||||||
|

|
||||||
|
xnu*/bsd/kern/mach_loader.c
|
||||||
|
details about loading Mach-o executables
|
||||||
|
xnu*/bsd/dev/ppc/unix_signal.c
|
||||||
|
details about sending signals to processes
|
||||||
|
xnu*/bsd/sys/*.h
|
||||||
|
headers that Xcode installs as /usr/include/sys/*.h
|
||||||
|
xnu*/bsd/man/man2/*.2
|
||||||
|
manual pages that Xcode installs as /usr/share/man/man2/*.2
|
||||||
|
Libc*/ppc/sys/SYS.h
|
||||||
|
Libc*/ppc/sys/*.s
|
||||||
|
assembly code (in gas syntax) for making system calls
|
||||||
|
|
||||||
|
The 10.4.11.ppc sources are wrong for Intel; use 10.4.11.x86 or 10.5
|
||||||
|
or newer. 10.5 moved SYS.h to xnu*/libsyscall/custom/SYS.h
|
||||||
|
|
||||||
|
The kernel maps a common page into every process, and Apple's Libc
|
||||||
|
uses the common page to speed up system calls like gettimeofday(2).
|
||||||
|
Our libsys does not use the common page.
