The gdbstub implementation for the Sparc architecture would incorrectly calculate the the floating point register offset. This resulted in, for example, registers f32 and f34 to point to the same value. The issue was caused by the confusion between even register numbers and even register indexes. For example, the register index of f32 is 64 and f34 is 65. Cc: qemu-stable@nongnu.org Fixes: 30038fd81808 ("target-sparc: Change fpr representation to doubles.")

2024-12-20accel/tcg: Include missing 'exec/translation-block.h' headerPhilippe Mathieu-Daudé1-0/+1
TB compile flags, tb_page_addr_t type, tb_cflags() and few other methods are defined in "exec/translation-block.h". All these files don't include "exec/translation-block.h" but include "exec/exec-all.h" which include it. Explicitly include "exec/translation-block.h" to be able to remove it from "exec/exec-all.h" later when it won't be necessary.

The TranslationBlock flags are defined in 'exec/translation-block.h'. tcg_cflags_has/set() use them, it is more logical to declare them in the same place. Move them there too.

Now that all of the Property arrays are counted, we can remove the terminator object from each array. Update the assertions in device_class_set_props to match. With struct Property being 88 bytes, this was a rather large form of terminator. Saves 30k from qemu-system-aarch64.
