A build error on x86_64 with x32 abi was reported here ( https://sourceware.org/pipermail/gdb/2021-November/049787.html ): ... gdb/nat/amd64-linux-siginfo.c:280:42: error: \ 'struct compat_x32_siginfo_t::<unnamed union>::<unnamed>' has no member \ named 'si_addr_bnd' 280 | #define cpt_si_lower _sifields._sigfault.si_addr_bnd._lower | ^~~~~~~~~~~ gdb/nat/amd64-linux-siginfo.c:337:38: note: in expansion of macro 'cpt_si_lower' 337 | to->cpt_si_lower = from_ptrace.cpt_si_lower; | ^~~~~~~~~~~~ ... The problem is that code added in commit d3d7d1ba3bb "[gdb/tdep] Handle si_addr_bnd in compat_siginfo_from_siginfo" doesn't compile on an x86_64 x32 setup, because compat_x32_siginfo_t doesn't have the si_addr_bnd fields. Fix this conservatively by disabling the code for x32. Tested on x86_64-linux.
