* linux-user: Standardize on ELF_MACHINE not ELF_ARCHRichard Henderson2025-08-301-1/+1
| | | | | | | | | | | | | | | | | 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.

* linux-user/mips: Use target_ulong for target_elf_greg_tRichard Henderson2025-08-301-8/+6
| | | | | | | | | | | Make use of the fact that target_elf_gregset_t is a proper structure. The target_ulong type matches the abi_ulong/abi_ullong selection within mips64/target_elf.h. Drop ELF_NREG, target_elf_greg_t, and tswapreg. Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
* linux-user: Move elf_core_copy_regs to mips/elfload.cRichard Henderson2025-08-301-0/+13
| | | | | | | | | Move elf_core_copy_regs to elfload.c. Move HAVE_ELF_CORE_DUMP, ELF_NREGS, target_elf_gregset_t to target_elf.h. For now, duplicate the definitions of target_elf_greg_t and tswapreg.

| | | | | | | | | Pass in CPUState; define HAVE_ELF_BASE_PLATFORM. Since this was the only instance of ELF_BASE_PLATFORM, go ahead and provide the stub definition for other platforms.

| | | | | | | | | | Rename from cpu_get_model to emphasize that this is an elf-specific function. Declare the function once in loader.h. This frees up target_elf.h for other uses. Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>

Instead of a sequence of "#if ... #endif" move the selection to a function in linux-user/*/target_elf.h We can't add them in linux-user/*/target_cpu.h because we will need to include "elf.h" to use ELF flags with eflags, and including "elf.h" in "target_cpu.h" introduces some conflicts in elfload.c Suggested-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Laurent Vivier <laurent@vivier.eu> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Message-Id: <20180220173307.25125-2-laurent@vivier.eu>
