target/s390x: Add remaining switches to compile with --disable-tcg Adding some CONFIG_TCG tests to be finally able to compile QEMU on s390x also without TCG.

s390x/tcg: add basic MSA features The STFLE bits for the MSA (extension) facilities simply indicate that the respective instructions can be executed. The QUERY subfunction can then be used to identify which features exactly are available. Availability of subfunctions can also vary on real hardware. For now, we simply implement a CPU model without any available subfunctions except QUERY (which is always around). As all MSA functions behave quite similarly, we can use one translation handler for now. Prepare the code for implementation of actual subfunctions. At least MSA is helpful for now, as older Linux kernels require this facility when compiled for a z9 model. Allow to enable the facilities for the qemu cpu model.

s390x/tcg: Implement VECTOR FP ADD 1. We'll reuse op_vfa() for similar instructions later, prepare for that. 2. We'll reuse vop64_3() for other instructions later. 3. Take care of modifying the vector register only if no trap happened. - on traps, flags are not updated and no elements are modified - traps don't modify the fpc flags - without traps, all exceptions of all elements are merged 4. We'll reuse check_ieee_exc() later when we need the XxC flag. We have to check for exceptions after processing each element. Provide separate handlers for single/all element processing. We'll do the same for all applicable FP instructions. Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: David Hildenbrand <david@redhat.com>

s390x/cpumodel: generate CPU feature lists for CPU models This patch introduces the helper "gen-features" which allows to generate feature list definitions at compile time. Its flexibility is better and the error-proneness is lower when compared to static programming time added statements. The helper includes "target-s390x/cpu_features.h" to be able to use named facility bits instead of numbers. The generated defines will be used for the definition of CPU models. We generate feature lists for each HW generation and GA for EC models. BC models are always based on a EC version and have no separate definitions. Base features: Features we expect to be always available in sane setups. Migration safe - will never change. Can be seen as "minimum features required for a CPU model". Default features: Features we expect to be stable and around in latest setups (e.g. having KVM support) - not migration safe. Max features: All supported features that are theoretically allowed for a CPU model. Exceeding these features could otherwise produce problems with IBC (instruction blocking controls) in KVM.

# build and run feature list generator
Move target-* CPU file into a target/ folder We've currently got 18 architectures in QEMU, and thus 18 target-xxx folders in the root folder of the QEMU source tree. More architectures (e.g. RISC-V, AVR) are likely to be included soon, too, so the main folder of the QEMU sources slowly gets quite overcrowded with the target-xxx folders. To disburden the main folder a little bit, let's move the target-xxx folders into a dedicated target/ folder, so that target-xxx/ simply becomes target/xxx/ instead.

rules.mak: quiet-command: Split command name and args to print The quiet-command make rule currently takes two arguments: the command and arguments to run, and a string to print if the V flag is not set (ie we are not being verbose). By convention, the string printed is of the form " NAME some args". Unfortunately to get nicely lined up output all the strings have to agree about what column the arguments should start in, which means that if we add a new quiet-command usage which wants a slightly longer CMD name then we either put up with misalignment or change every quiet-command string. Split the quiet-mode string into two, the "NAME" and the "same args" part, and use printf(1) to format the string automatically. This means we only need to change one place if we want to support a longer maximum name. In particular, we can now print 7-character names lined up properly (they are needed for the OSX "SETTOOL" invocation). Change all the uses of quiet-command to the new syntax. (Any which are missed or inadvertently reintroduced via later merges will result in slightly misformatted quiet output rather than disaster.) A few places in the pc-bios/ makefiles are updated to use "BUILD", "SIGN" and "STRIP" rather than "Building", "Signing" and "Stripping" for consistency and to keep them below 7 characters.
