Propagate the use of target_desc unique pointers further. Basically, avoid releasing target_desc objects, except in some spots in gdbserver (e.g. netbsd) where we don't currently have a persistent container for created target descriptions (and the target desc just leaks). Introduce const_target_desc_up to change some `const target_desc *` to a unique pointer without loss of constness. Architectures that use the old regformats/regdat.sh don't need to be changed, because their target_desc objects are statically allocated in the generated files. I was able to built-test these native configs: - Linux AArch64 - Linux ARC - Linux AMD64 - Linux ARM - Linux LoongArch - Linux M68K - Linux Microblaze - Linux MIPS (32 and 64) - Linux or1k - Linux PPC (32 and 64) - Linux RISC-V - Linux s390x - Linux SH4 - Linux Sparc (32 and 64) - Linux Xtensa - FreeBSD AMD64 - NetBSD AMD64 - Windows i686 - Windows AMD64 For the rest, I did my best by staring at the code long enough. I probably missed or messed some spots, but that shouldn't be difficult to fix. Change-Id: I8db8790c57942edd2bfe890987157e2dc0c67879 Reviewed-by: Thiago Jung Bauermann <thiago.bauermann@linaro.org>
