Hi All, This patch series adds system-mode big-endian support for ARM. It also implements the setend instruction, and loading of BE binaries even in LE emulation mode.
Based on Paolo's original work. I have tested all of LE, BE8 and BE32 in both linux-user mode (for regressions) and system mode (BE8 and BE32 are new here). My test application is here, the README gives some example command lines you can run: https://github.com/pcrost/arm-be-test Regards, Peter Changed since v1: Addressed PMM review Added doc comments to new/changed loader.h APIs Paolo Bonzini (8): linux-user: arm: fix coding style for some linux-user signal functions linux-user: arm: pass env to get_user_code_* target-arm: implement SCTLR.B, drop bswap_code linux-user: arm: handle CPSR.E correctly in strex emulation target-arm: pass DisasContext to gen_aa32_ld*/st* target-arm: introduce disas flag for endianness target-arm: implement setend target-arm: implement BE32 mode in system emulation Peter Crosthwaite (10): target-arm: cpu: Move cpu_is_big_endian to header arm: cpu: handle BE32 user-mode as BE linux-user: arm: set CPSR.E/SCTLR.E0E correctly for BE mode target-arm: implement SCTLR.EE target-arm: a64: Add endianness support target-arm: introduce tbflag for endianness loader: add API to load elf header loader: load_elf(): Add doc comment loader: Add data swap option to load-elf arm: boot: Support big-endian elfs hw/alpha/dp264.c | 4 +- hw/arm/armv7m.c | 2 +- hw/arm/boot.c | 93 +++++++++- hw/core/loader.c | 64 ++++++- hw/cris/boot.c | 2 +- hw/i386/multiboot.c | 3 +- hw/lm32/lm32_boards.c | 4 +- hw/lm32/milkymist.c | 2 +- hw/m68k/an5206.c | 2 +- hw/m68k/dummy_m68k.c | 2 +- hw/m68k/mcf5208.c | 2 +- hw/microblaze/boot.c | 4 +- hw/mips/mips_fulong2e.c | 2 +- hw/mips/mips_malta.c | 2 +- hw/mips/mips_mipssim.c | 2 +- hw/mips/mips_r4k.c | 2 +- hw/moxie/moxiesim.c | 3 +- hw/openrisc/openrisc_sim.c | 3 +- hw/pci-host/prep.c | 2 +- hw/ppc/e500.c | 2 +- hw/ppc/mac_newworld.c | 5 +- hw/ppc/mac_oldworld.c | 5 +- hw/ppc/ppc440_bamboo.c | 3 +- hw/ppc/spapr.c | 6 +- hw/ppc/virtex_ml507.c | 3 +- hw/s390x/ipl.c | 4 +- hw/sparc/leon3.c | 2 +- hw/sparc/sun4m.c | 4 +- hw/sparc64/sun4u.c | 4 +- hw/tricore/tricore_testboard.c | 2 +- hw/xtensa/sim.c | 4 +- hw/xtensa/xtfpga.c | 2 +- include/hw/arm/arm.h | 9 + include/hw/elf_ops.h | 22 ++- include/hw/loader.h | 41 ++++- linux-user/main.c | 77 ++++++-- linux-user/signal.c | 110 +++++------ target-arm/arm_ldst.h | 8 +- target-arm/cpu.c | 21 +-- target-arm/cpu.h | 98 +++++++++- target-arm/helper.c | 31 +++- target-arm/helper.h | 1 + target-arm/op_helper.c | 5 + target-arm/translate-a64.c | 56 +++--- target-arm/translate.c | 405 ++++++++++++++++++++++++----------------- target-arm/translate.h | 3 +- 46 files changed, 783 insertions(+), 350 deletions(-) -- 1.9.1
