2020-07-15tests/plugins: don't unconditionally add -WpsabiAlex Bennée1-0/+3
Not all compilers support the -Wpsabi (clang-9 in my case). To handle this gracefully we pare back the shared build machinery so the Makefile is relatively "standalone". We still take advantage of config-host.mak as configure has done a bunch of probing for us but that is it.

2020-07-13osdep.h: Always include <sys/signal.h> if it existsDavid CARLIER1-0/+10
Regularize our handling of <sys/signal.h>: currently we include it in osdep.h, but only for OpenBSD, and we include it without an ifdef guard in a couple of C files. This causes problems for Haiku, which doesn't have that header. Instead, check in configure whether sys/signal.h exists, and if it does then always include it from osdep.h.

2020-07-13build: Check that mlockall() existsDavid CARLIER1-0/+15
Instead of assuming that all POSIX platforms provide mlockall(), test for it in configure. If the host doesn't provide this platform then os_mlock() will fail -ENOSYS, as it does already on Windows. This is necessary for Haiku, which does not have mlockall().

2020-06-26configure: add libdaxctl supportJingqi Liu1-0/+29
Add a pair of configure options --{enable,disable}-libdaxctl to control whether QEMU is compiled with libdaxctl [1]. Libdaxctl is a utility library for managing the device dax subsystem. QEMU uses mmap(2) to maps vNVDIMM backends and aligns the mapping address to the page size (getpagesize(2)) by default. However, some types of backends may require an alignment different than the page size. The 'align' option is provided to memory-backend-file to allow users to specify the proper alignment. For device dax (e.g., /dev/dax0.0), the 'align' option needs to match the alignment requirement of the device dax, which can be fetched through the APIs of libdaxctl version 57 or up. [1] Libdaxctl is a part of ndctl project. The project's repository is: https://github.com/pmem/ndctl For more information about libdaxctl APIs, you can refer to the comments in source code of: pmem/ndctl/daxctl/lib/libdaxctl.c.

2020-06-23configure: add flags to support SafeStackDaniele Buono1-0/+73
This patch adds a flag to enable/disable the SafeStack instrumentation provided by LLVM. On enable, make sure that the compiler supports the flags, and that we are using the proper coroutine implementation (coroutine-ucontext). On disable, explicitly disable the option if it was enabled by default. While SafeStack is supported only on Linux, NetBSD, FreeBSD and macOS, we are not checking for the O.S. since this is already done by LLVM.

2020-06-18configure: Add -Wno-psabiRichard Henderson1-0/+1
On aarch64, gcc 9.3 is generating qemu/exec.c: In function ‘address_space_translate_iommu’: qemu/exec.c:431:28: note: parameter passing for argument of type \ ‘MemTxAttrs’ {aka ‘struct MemTxAttrs’} changed in GCC 9.1 and many other repetitions. This structure, and the functions amongst which it is passed, are not part of a QEMU public API. Therefore we do not care how the compiler passes the argument, so long as the compiler is self-consistent. The only portion of QEMU which does have a public api, and so must have a stable abi, is "qemu/plugin.h". We test this by forcing -Wpsabi in tests/plugin/Makefile.

2020-06-16configure: add --enable-tsan flag + fiber annotations for coroutine-ucontextLingfeng Yang1-1/+46
We tried running QEMU under tsan in 2016, but tsan's lack of support for longjmp-based fibers was a blocker: https://groups.google.com/forum/#!topic/thread-sanitizer/se0YuzfWazw Fortunately, thread sanitizer gained fiber support in early 2019: https://reviews.llvm.org/D54889 This patch brings tsan support upstream by importing the patch that annotated QEMU's coroutines as tsan fibers in Android's QEMU fork: https://android-review.googlesource.com/c/platform/external/qemu/+/844675 Tested with '--enable-tsan --cc=clang-9 --cxx=clang++-9 --disable-werror' configure flags.

2020-05-14target/arm: Use correct GDB XML for M-profile coresPeter Maydell1-2/+2
GDB's remote protocol requires M-profile cores to use the feature name 'org.gnu.gdb.arm.m-profile' instead of the 'org.gnu.gdb.arm.core' feature used for A- and R-profile cores. We weren't doing this, which meant GDB treated our M-profile cores like A-profile ones. This mostly doesn't matter, but for instance means that it doesn't correctly handle backtraces where an M-profile exception frame is involved. Ship a copy of GDB's arm-m-profile.xml and use it on the M-profile cores. The integer registers have the same offsets as the arm-core.xml, but register 25 is the M-profile XPSR rather than the A-profile CPSR, so we need to update arm_cpu_gdb_read_register() and arm_cpu_gdb_write_register() to handle XSPR reads and writes.

Currently "cf-core.xml" is sent to GDB when using any m68k flavor. Thing is it uses the "org.gnu.gdb.coldfire.core" feature name and gdb 8.3 then expects a coldfire FPU instead of the default m68881 FPU. This is not OK because the m68881 floats registers are 96 bits wide so it crashes GDB with the following error message: (gdb) target remote localhost:7960 Remote debugging using localhost:7960 warning: Register "fp0" has an unsupported size (96 bits) warning: Register "fp1" has an unsupported size (96 bits) ...
