[Qemu-devel] Compiling on AMD64

[Pavel Janík]

Hi,

there are several warning emitted while compiling on AMD64 target system:

gcc -Wall -O1 -g -D_GNU_SOURCE -o dyngen dyngen.c
dyngen.c: In function `gen_code':
dyngen.c:1109: warning: int format, different type arg (arg 4)
dyngen.c:1269: warning: int format, different type arg (arg 3)
dyngen.c:1273: warning: int format, different type arg (arg 3)
dyngen.c:1277: warning: int format, different type arg (arg 3)
dyngen.c:1277: warning: int format, different type arg (arg 5)

All those warnings come from

    host_ulong start_offset;

    fprintf(outfile, "    memcpy(gen_code_ptr, (void *)((char *)&%s+%d), %d);\n", name, start_offset - offset, copy_size);

where host_ulong (int64_t in case of AMD64) is formatted to %d.

Don't patch bad code - rewrite it.

I was just about to repost yesterday IRC session where i tried to get qemu
working on AMD64 ( thanx Pavel!! :-) )

I cannot compile user-i386/* with gcc 3.4 CVS (ok, it is just cvs from 3.4 
branch, so it should be gcc 3.4 with bugfixes...) unless i remove the "-O2"
compilation flag (this is a gcc bug).

After compiling i got error in 

 gcc -g -Wl,-T,/home/maurizio/qemu/amd64.ld -o qemu-i386 elfload.o main.o 
syscall.o mmap.o signal.o path.o osdep.o thunk.o vm86.o libqemu.a   -lm

/usr/bin/ld:/home/maurizio/qemu/amd64.ld:62: parse error

error is on lines 62,63,89, etc of /home/maurizio/qemu/amd64.ld. I tried to
reinstall binutils just to be sure (GNU ld version 2.15) but with no succes.
it looks like ld doesn't understand ONLY_IF_RO and ONLY_IF_RW, but i can't
fixe it because this is the first time i see a .ld file :-)

I hope i am not forgetting anything...

Ciao
