33 hourstarget/arm: Drop ARM_FEATURE_IWMMXT handlingPeter Maydell2-68/+0
We have now removed all the CPU types which had the Intel XScale extensions indicated via ARM_FEATURE_IWMMXT, so this feature bit is never set. Remove all the code that can only be reached when using this flag.

33 hourslinux-user/aarch64: Check syndrome for EXCP_UDEFRichard Henderson1-1/+74
Note that we have been passing the incorrect code for most exception codes: uncategorized (do_el0_undef), systemregistertrap (do_el0_sys), smetrap (do_sme_acc), btitrap (do_el0_bti) and illegalstate (bad_el0_sync). Only pacfail uses ILL_ILLOPN (do_el0_fpac). Note that EC_MOP (do_el0_mops) ought not signal at all. For now, preserve existing behavior signalling ILL_ILLOPN. List all other exception codes and document why they do not apply to user-only.

2025-08-30linux-user: Standardize on ELF_MACHINE not ELF_ARCHRichard Henderson20-26/+20
PowerPC was the one outlier that defined both ELF_ARCH and ELF_MACHINE; ELF_ARCH was defined incorrectly, necessitating the definition of elf_check_arch. However, the elf file header field in question is called e_machine, so ELF_MACHINE is in fact the better name. Mechanically change most target/target_elf.h files, then adjust ppc/target_elf.h manually. Do not provide a default for ELF_MACHINE.
