[Qemu-devel] Building qemu on UltraSparc

I'm trying to build qEmu v0.7.0 on Debian Sarge on a Sparc64 machine,
and it fails with strange errors.
Does anybody here have any idea to help me achieve it?

I attach the log of the build to this mail.

Thanks

well, looks like you hit 32 vs 64 bit issues here, don't know
the details about the sparc/64 support but I'd try to build
as sparc32 first and see how far that gets ...

I tried that (starting with utility sparc32), and it even fails faster.
See the log attached.

SPARC Host support is quite broken at this time, it seems.

Yep, the macro GOTO_LABEL_PARAM is not defined for the sparc platform.

This needs to be fixed in dyngen-exec.h, with something like this:

sparc64 probably needs a similar change to support WDISP22 relocations.

That's another issue with sparc host support. x86 MMX instruction
support was added to qemu some time ago, and the compiler needs a *lot*
of register variables for the MMX opcode code templates.  Problem is
that on sparc a lot of cpu registers are already in use as "global
register" variables: most sparc global registers g1-g3, g6 and all local
registers l0-l7.  So the compiler starts to generate code that uses
frame pointer relative temporary variables in memory, because it's
running out of free cpu registers.  The use of temporary variables in
memory is incompatible with the way qemu's dyngen code generator works
on sparc.  That's basically what dyngen seems to be complaining about.



I've fixed this for now for Solaris SPARC host support, by reducing the
number of global cpu registers to just the global registers (g2-g6) -
freeing the local registers l0-l7.  With that change op_pavgb_mmx
doesn't need temporary variables in the local stack frame any more.

All of the above changes are part of bigger Solaris x86 / Solaris SPARC
/ FreeBSD / NetBSD patch that I'll attach below.


This patch won't immediately fix the issues that you've got on
linux/sparc, but it should give you some ideas where to start fixing
the build issues.

You probably did your diff against CVS? I have tried it using with clean 0.7.0 
distribution (gpatch -p0 < ../qemu-solaris-freebsd-netbsd--patch) and got the

This has not been a problem. I have done the following configure call then:

Any idea what is happening here?

I have done this on Solaris 9 on a Sun Fire v250 with gcc-3.4.2 and native 
ld/as.

Yes, the patch was against current qemu cvs sources.

Part of the problem is my GOTO_LABEL_PARAM macro for sparc, in dyngen-exec.h:

    #define GOTO_LABEL_PARAM(n) asm volatile ("ba " ASM_NAME(__op_gen_label) #n 
";nop")


We have 22 bits in the branch instruction to encode a signed 32-bit word
offset, relative to the current PC. The target address is always a
multiple of 4, so the offset encoded in the branch instruction is an
offset measured in 32-bit words.


The sparc branch instructions cannot jump forward / backward more than
8 mbytes (2^21 * 4 = 8mbyte).


What appears to be happening on your system is that the opcode
templates from the code section for "target-i386/op.c" (these contain
the "ba" branch instruction from the GOTO_LABEL_PARAM macro) jump to an
integer variable that is allocated somewhere in the data or bss section
(the "int __op_gen_label1" variable defined in dyngen.h), and the code
& data section on your system are more than 8 mbytes apart.


Apparently I had luck upto now, because on my solaris 10 sparc box there
have been no such issues with R_SPARC_WDISP22 relocation errors.

  --> 0x34c21f * 4 = 13830268 = 13.8 mbytes


I guess this can be fixed by moving the branch target "__op_gen_label1"
from the data section to the code section.  A "size" on my sparc qemu
binary reports a total code size of ~ 1 mbyte, so that there should be
no issues with R_SPARC_WDISP22 overflows when both the branch instruction
and the branch target are both in the code (.text) section.

A fix would be:

Although I do not fully understand your explanation ... it works now with your

Does this stuff go into CVS?
