Exec summary: strange QEMU bug triggered by RELEASE_GCC5 code, which
is caused by a spurious write to the NOR flash at runtime. The latter
is also a bug, in Tianocore.

So the reason this happens is that get_page_addr_code() doesn't
correctly handle the case of the memory region being a
ROM that's not in ROMD mode. That is, the flash memory can
be either in "reads ma

Yeah, we shoul
Hello all,
I am hitting this strange issue when executing the UEFI firmware for
QEMU mach-virt/AArch64. This only occurs when building the firmware
with GCC5 in RELEASE mode, but the failure mode suggests that this may
not be relevant.
Running a aarch64-softmmu QEMU built from today's master, I g

Hi all,
While searching for QEMU SIMD issues, I found there was a paper presented
in 2011 [1], and the source code is also public on [2]. However, it seems
this project doesn't make any progress since last year. I update their
change to upstream and you can download from here:
