2023-11-02linux-user: Report AArch64 hwcap2 fields above bit 31Peter Maydell2-5/+5
The AArch64 ELF hwcap2 field is 64 bits, but our get_elf_hwcap2() works with uint32_t, so it accidentally fails to report any hwcaps over bit 31. Use uint64_t here. The Arm hwcap2 is only 32 bits (because the ELF format makes these fields be the size of "long" in the ABI), but since it shares the prototype declaration for get_elf_hwcap2() it is easier to also expand it to 64 bits. The only hwcap fields we implement already that are affected by this are the HBC and MOPS ones, neither of which were implemented in a previous release, so this doesn't need backporting to older stable branches.

2023-10-30linux-user: Do not clobber bprm_buf swapping ehdrRichard Henderson1-11/+14
Rearrange the allocation of storage for ehdr between load_elf_image and load_elf_binary. The same set of copies are done, but we don't modify bprm_buf, which will be important later.

2023-10-30linux-user: Fix guest signal remapping after adjusting SIGABRTRichard Henderson1-5/+4
The arithmetic within the loop was not adjusted properly after SIGRTMIN was stolen for the guest SIGABRT. The effect was that the guest libc could not send itself __SIGRTMIN to wake sleeping threads.

2023-10-27target/arm: Move feature test functions to their own headerPeter Maydell6-0/+13
The feature test functions isar_feature_*() now take up nearly a thousand lines in target/arm/cpu.h. This header file is included by a lot of source files, most of which don't need these functions. Move the feature test functions to their own header file.

2023-10-18linux-user: Remap guest SIGABRTRichard Henderson1-7/+35
Distinguish host SIGABRT from guest SIGABRT by mapping the guest signal onto one of the host RT signals. This prevents a cycle by which a host assertion failure is caught and handled by host_signal_handler, queued for the guest, and then we attempt to continue past the host abort. What happens next depends on the host libc, but is neither good nor helpful. Acked-by: Helge Deller <deller@gmx.de> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
