Looking through old bug tickets... is this still an issue with the
latest version of QEMU? Or could we close this ticket nowadays?

Title:
-d option outs wrong info about sections
Status in QEMU:
Incomplete
Bug description:
For example, after run ./qemu-i386 -d in_asm /bin/ls from 0.14.0 release, I
received this qemu.log file:
$ cat /tmp/qemu.log | grep -A7 guest
Relocating guest address space from 0x08048000 to 0x8048000
guest_base 0x0
start end size prot
00048000-0005f000 00017000 r-x
0005f000-00069000 0000a000 rw-
00040000-00041000 00001000 ---
00041000-00041800 00000800 rw-
00041800-0005d800 0001c000 r-x
0005d800-0005f800 00002000 rw-
But such command in 0.12.5 release outs this:
$ cat /tmp/qemu.log | grep -A7 guest
guest_base 0x0
start end size prot
00f38000-00f39000 00001000 ---
08048000-0805f000 00017000 r-x
0805f000-08061000 00002000 rw-
40000000-40080000 00080000 rw-
40080000-40081000 00001000 ---
40081000-4009d000 0001c000 r-x
It looks correct.
I received such differences and with qemu-microblaze.
After comparing 0.12.5 and 0.14.0 releases I found this differences in exec.c:
in 0.12.5:
end = (i << (32 - L1_BITS)) | (j << TARGET_PAGE_BITS);
in 0.14.0:
int rc = walk_memory_regions_1(&data, (abi_ulong)i << V_L1_SHIFT,
V_L1_SHIFT in my case is 10, but 32 - L1_BITS is 22
I make this changes:
$ diff -up qemu-0.14.0/exec.c exec.c
--- qemu-0.14.0/exec.c 2011-04-08 17:26:00.524464002 +0400

TARGET_PAGE_BITS),
V_L1_SHIFT / L2_BITS - 1, l1_map + i);
if (rc != 0) {
return rc;
After this outputs looks correct.
I don't know code base good, and think what may to do more general
corrections.
