2020-01-24build-sys: clean up flags included in the linker command linePaolo Bonzini
Some of the CFLAGS that are discovered during configure, for example compiler warnings, are being included on the linker command line because QEMU_CFLAGS is added to it. Other flags, such as the -m32, appear twice because they are included in both QEMU_CFLAGS and LDFLAGS. All this leads to confusion with respect to what goes in which Makefile variables (and we have plenty). So, introduce QEMU_LDFLAGS for flags discovered by configure, following the lead of QEMU_CFLAGS, and stop adding to it: 1) options that are already in CFLAGS, for example "-g" 2) duplicate options At the same time, options that _are_ needed by both compiler and linker must now be added to both QEMU_CFLAGS and QEMU_LDFLAGS, which is clearer. This is mostly -fsanitize options. For now, --extra-cflags has this behavior (but --extra-cxxflags does not). Meson will not include CFLAGS on the linker command line, do the same in our build system as well.

2020-01-24target/i386: Add the 'model-id' for Skylake -v3 CPU modelsKashyap Chamarthy
This fixes a confusion in the help output. (Although, if you squint long enough at the '-cpu help' output, you _do_ notice that "Skylake-Client-noTSX-IBRS" is an alias of "Skylake-Client-v3"; similarly for Skylake-Server-v3.)

2020-01-24qdev: register properties as class propertiesMarc-André Lureau
Use class properties facilities to add properties to the class during device_class_set_props(). qdev_property_add_static() must be adapted as PropertyInfo now operates with classes (and not instances), so we must set_default_value() on the ObjectProperty, before calling its init() method on the object instance. Also, PropertyInfo.create() is now exclusively used for class properties. Fortunately, qdev_property_add_static() is only used in target/arm/cpu.c so far, which doesn't use "link" properties (that require create()).

Restrict all the system emulation and tools objects with a Makefile IF (CONFIG_SOFTMMU OR CONFIG_TOOLS) check. Using the same description over and over is not very helpful. Use it once, just before the if() block.

2020-01-24Makefile: Clarify all the codebase requires qom/ objectsPhilippe Mathieu-Daudé
QEMU user-mode also requires the qom/ objects, it is not only used by "system emulation and qemu-img". As we will use a big if() block, move it upper in the "Common libraries for tools and emulators" section.

We only require libfdt for system emulation, in a small set of architecture: 4077 # fdt support is mandatory for at least some target architectures, 4078 # so insist on it if we're building those system emulators. 4079 fdt_required=no 4080 for target in $target_list; do 4081 case $target in 4082 aarch64*-softmmu|arm*-softmmu|ppc*-softmmu|microblaze*-softmmu|mips64el-softmmu|riscv*-softmmu) 4083 fdt_required=yes Do not build libfdt if we did not manually specified --enable-fdt, or have one of the platforms that require it in our target list.
