Yeah, we expect Cygwin to mostly work, but I don't think anybody
actively keeps track of whether it does. It's best to use a VM or an
actual linux system for your build like you are now. If you do find a
bug, though, we'd be happy to have a fix.

Quoting "Tim Harris (RESEARCH)" <thar...@microsoft.com>:
I ran into a similar problem a while back when building M5 on 32-bit
Cygwin. Maybe this explains the early crash here:
It looked like some updates to the flags field defined on
StaticInstBase were being truncated. I was seeing IsLastMicroop
being lost, leading to assert-fails (m5.opt) / crashes (m5.fast).
decoder.cc was generating uint64_t initializers for the flags and
these were being passed intact to the X86MicroopBase constructor in
microop.hh. The constructor then initialized the flags bitset by
using:
flags |= setFlags;
(where flags is a std::bitset, and setFlags is a uint64_t).
I think the implementation of std::bitset I had with Cygwin was only
taking the bottom 32-bits, rather than splitting a uint64_t over two
32-bit words.
I meant to look into this further, and see whether this was a bug in
std::bitset, or in M5's use of it... but I was travelling, switched
to using Virtual PC, and unfortunately forgot to get back to the
problem.

Please try again with m5.opt. m5.fast has all the asserts and some
other debugging support turned off to get slightly better
performance, and there may be an earlier error that's not being
caught. I always use m5.opt, and I'd recommend you use it until
you're really confident no asserts would have gone off had they been
turned on. If it still fails in this same way, please send me your
binary.

Hi, Gabe
The application source are compiled with:
gcc --static hello.c -ohello
I also tried x64, and got the same 'Invalid microop' error when start m5:
gcc -m64 --static hello.c -ohello
The command line for compiling m5:
scons -j2 build/X86_SE/m5.fast
The command line for running m5:
build/X86_SE/m5.fast configs/example/se.py -c hello

Lets start with SE mode. How are you compiling your binary? What is
your command line? Also, what version of the gem5 source are you using?

Hi Gabe,
I compiled the kernel with ARCH=x86_64, and got the error:
panic: Invalid microop!
@ cycle 1000
In SE mode, whenever the binary file is compiled in 32bit or 64bit, I
always get:
panic: Invalid microop!
@ cycle 500

As the message says, it doesn't support 32 bit kernels. If you want
to use X86 FS you have to use a 64 bit kernel.

Did you mean your problems are due to the version of tools?
Mine is as follows:
gcc-4.4.3
python-2.6.5
scons-v1.2.0.d20100117.r4629
swig-1.3.40
m4-1.4.13
On the other hand, in FS mode I got 'fatal: Loading a 32 bit x86
kernel is not supported.', so I'm wondering if m5 already supports
the FS mode of x86.
The changeset of m5 is 8325:76095b05f4da.

Hi M5,
Few days ago, I got errors when running X86 FS and SE:
1. m5.debug: build/X86_FS/arch/x86/insts/macroop.hh:78: virtual
StaticInstPtr X86ISA::MacroopBase::fetchMicroop(MicroPC): Assertion
`microPC < numMicroops' failed.
2. Segmentation fault
Today, I use another server and again go through the steps mentioned
in the following mails.
http://www.mail-archive.com/m5-users@m5sim.org/msg04960.html
And it seems fine now!
Tool list of two servers:
Server A (got errors),
gcc-4.2.4
python-2.5.4
scons-v1.2.0.r3842
swig-1.3.36
m4-1.4.10
Server B (fine),
gcc-4.4.1
python-2.6.4
scons-v1.2.0.r3842
swig-1.3.36
m4-1.4.13
Thanks for everybody's help.
