Looking at the overall sources for the two versions ( as seen via
-r483807 and -r484565 ) I find a possibly-significant changed file:
# diff -u =
/wrkdirs/usr/ports/emulators/qemu-user-static/*work/qemu-bsd-user-*/bsd-us=
er/mmap.c | more
--- =
/wrkdirs/usr/ports/emulators/qemu-user-static/483807-work/qemu-bsd-user-49=
5fb3a/bsd-user/mmap.c 2018-05-25 07:28:13.000000000 -0700
+++ =
/wrkdirs/usr/ports/emulators/qemu-user-static/484565-work/qemu-bsd-user-2c=
b0cdd/bsd-user/mmap.c 2018-11-09 09:27:18.000000000 -0800
(I'll not list much of the differences here.)
It includes things like:
-static abi_ulong mmap_find_vma_reserved(abi_ulong start, abi_ulong =
size)
+static abi_ulong mmap_find_vma_reserved(abi_ulong start, abi_ulong =
size, abi_ulong alignment)
. . .
-abi_ulong mmap_find_vma(abi_ulong start, abi_ulong size)
+static abi_ulong mmap_find_vma_aligned(abi_ulong start, abi_ulong size, =
abi_ulong alignment)
. . .
+abi_ulong mmap_find_vma(abi_ulong start, abi_ulong size)
+{
+ return mmap_find_vma_aligned(start, size, 0);
+}
+
and changes inside:
abi_long target_mmap(abi_ulong start, abi_ulong len, int prot,
int flags, int fd, off_t offset)
This looks like it might change what address ranges are used.
(But I do not claim familiarity with the code or its use.)
