Hi,
I have built u-boot binary for 'qemu-system-mips -M mips'.
It is fine to run ths u-boot binary.
But the same u-boot binary does not run on 'qemu-system-mips64 -M mips'.
I do not understand what happends on the qemu-mips64 execution.
Is this a bug for qemu-system-mips64 ?
Or should I build u-boot binary by another configuration?
------
* u-boot building steps
(1) build the gcc 4.5 cross-compiler for mips from the source.
(2) build u-boot(2010.03) by the (1)compiler.
(3) copy the u-boot.bin to /usr/share/qemu/mips_bios.bin
* qemu(mips) execution command
$ qemu-system-mips -L /usr/share/qemu -d in_asm -nographic
* get /tmp/qemu.log
the execution seems fine.
* qemu(mips64) execution command
$ qemu-system-mips64 -L /usr/share/qemu -d in_asm -nographic
* get /tmp/qemu.log
the execution seems not fine. Something is wrong?

Hi,
I should have written the infomation for u-boot's board configuration.
> (2) build u-boot(2010.03) by the (1)compiler.
I rewrite configuration file for 'qemu-mips':
u-boot-2010.03/board/qemu-mips/u-bool.lds
--[original]
/*
OUTPUT_FORMAT("elf32-bigmips", "elf32-bigmips", "elf32-bigmips")
*/
OUTPUT_FORMAT("elf32-tradbigmips", "elf32-tradbigmips", "elf32-tradbigmips")
--[new]
OUTPUT_FORMAT("elf32-bigmips", "elf32-bigmips", "elf32-bigmips")
/*
OUTPUT_FORMAT("elf32-tradbigmips", "elf32-tradbigmips", "elf32-tradbigmips")
*/
---
And I use 'qemu-mips' board configuration for building u-boot.
$ cd u-boot-2010.03
$ make qemu_mips_config
$ make all
( I get 'u-boot.bin' )
Regards,
Noritaka KAWAKATSU.

so EPC is set to ffffffffbfc0ee94 which is :
movn s1,v1,v0
>From what I understand when reading the mips IV manual, the movn ins is
only for mips IV / 32bit and not 64bit. Looks like the qemu code has

I understand that the relaation between MIPS32/MIPS64 arch is upper compatible
(from MIPS32 to MIPS64).
I wonder if this fact (the movn ins is only for mips IV / 32bit and not 64bit)
be true, umm.
Please let me know the list of instructions like this (32/64 not compatible)
if you know, or give me a hint to investigate?

I report the workaround for u-boot execution on qemu-system-mips64.

I have rebuilt u-boot by the configuration customed for R4400 architecture:
>From original gcc option script '-march=4kc ..' to '-march=r4400 ..'.
R4400 has inst set without 'movn'.
The binary built by this process runs on
both 'qemu-system-mips' and 'qemu-system-mips64'.
Thank you.
