The docker-run-test-build@debian-s390x-cross target fails with: strip --strip-unneeded s390-ccw.elf -o s390-ccw.img strip: Unable to recognise the format of the input file `s390-ccw.elf' The configure script defines a STRIP makefile variable whose default value is ${cross_prefix}strip. Let's use it. We default to using the non-prefixed strip command in case --enable-debug or --disable-strip was passed to configure during a regular build.

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. Module .mo links now print "LD" rather than the nonstandard "LD -r".

Since commit a9c87304 ("build-sys: fix building with make CFLAGS=.. argument") pc-bios/s390-ccw.img build might fail with --- snip --- main.o: In function `virtio_setup': qemu/pc-bios/s390-ccw/main.c:117: undefined reference to `__stack_chk_fail' --- snip --- Changing the CFLAGS to QEMU_CFLAGS does the trick. We also need to add -fno-strict-aliasing as this was filtered out.

Newer distributions have an architecture level set to z9, z196 or similar - also as default option for the compiler. We should build the bios for z900 to allow it to run with all 64bit CPUs. This will become more important as soon as QEMU/KVM does support CPU models.

Some gcc versions (e.g. Fedora 22 gcc 5.1.1) seem to use floating point registers for spilling and filling of general purpose registers. As the BIOS does not activate the AFP register setting of CR0 this can cause data exception program checks. Disallow floating point in the BIOS as a simple solution.

Starting with version 4.9, GCC assumes it can't safely dereference null pointers, and uses this for some optimizations. On s390, the lowcore memory is located at address 0, so this assumption is wrong and breaks the s390-ccw firmware. Pass -fdelete-null-pointer-checks to avoid that.

The current bios sits at location 0x7e00000 in the guest RAM and thus prevents loading of bigger ramdisks. By making the image relocatable we can move it to the end of the RAM so that it is getting out of the way.
