2022-04-21compiler.h: replace QEMU_NORETURN with G_NORETURNMarc-André Lureau
G_NORETURN was introduced in glib 2.68, fallback to G_GNUC_NORETURN in glib-compat. Note that this attribute must be placed before the function declaration (bringing a bit of consistency in qemu codebase usage).

This buffering was introduced during the Paleozoic: 9fa3e853531. There has never been an explanation as to why we may not allow glibc to allocate the file buffer itself.

Replace a config-time define with a compile time condition define (compatible with clang and gcc) that must be declared prior to its usage. This avoids having a global configure time define, but also prevents from bad usage, if the config header wasn't included before.

2022-03-22linux-user: Fix syscall parameter handling for MIPS n32WANG Xuerui
The MIPS n32 ABI is basically n64 with the address space (i.e. pointer width) shrinked to 32 bits. Meanwhile the current code treats it as o32-like based on TARGET_ABI_BITS, which causes problems with n32 syscalls utilizing 64-bit offsets, like pread64, affecting most (if not all) recently built n32 binaries. This partially solves issue #909 ("qemu-mipsn32(el) user mode emulator fails to execute any recently built n32 binaries"); with this change applied, the built qemu-mipsn32el is able to progress beyond the pread64, and finish _dl_start_user for the "getting ld.so load libc.so" case. The program later dies with SIGBUS, though, due to _dl_start_user not maintaining stack alignment after removing ld.so itself from argv, and qemu-user starting to enforce alignment recently, but that is orthogonal to the issue here; the more common case of chrooting is working, verified with my own-built Gentoo n32 sysroot. (Depending on the exact ISA used, one may have to explicitly specify QEMU_CPU, which is the case for my chroot.)

g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer, for two reasons. One, it catches multiplication overflowing size_t. Two, it returns T * rather than void *, which lets the compiler catch more type errors. This commit only touches allocations with size arguments of the form sizeof(T).

2022-03-08linux-user: Remove stale "not threadsafe" commentsPeter Maydell
In linux-user/signal.c we have two FIXME comments claiming that parts of the signal-handling code are not threadsafe. These are very old, as they were first introduced in commit 624f7979058 in 2008. Since then we've radically overhauled the signal-handling logic, while carefully preserving these FIXME comments. It's unclear exactly what thread-safety issue the original author was trying to point out -- the relevant data structures are in the TaskStruct, which makes them per-thread and only operated on by that thread. The old code at the time of that commit did have various races involving signal handlers being invoked at awkward times; possibly this was what was meant. Delete these FIXME comments: * they were written at a time when the way we handled signals was completely different * the code today appears to us to not have thread-safety issues * nobody knows what the problem the comments were trying to point out was so they are serving no useful purpose for us today.

2022-02-09target/ppc: Remove PowerPC 601 CPUsCédric Le Goater
The PowerPC 601 processor is the first generation of processors to implement the PowerPC architecture. It was designed as a bridge processor and also could execute most of the instructions of the previous POWER architecture. It was found on the first Macs and IBM RS/6000 workstations. There is not much interest in keeping the CPU model of this POWER-PowerPC bridge processor. We have the 603 and 604 CPU models of the 60x family which implement the complete PowerPC instruction set.

2022-01-27linux-user: Fix inotify on aarch64Paul Brook
The inotify implementation originally called the raw host syscalls. Commit 3b3f24add0 changed this to use the glibc wrappers. However ifdefs in syscall.c still test for presence of the raw syscalls. This causes a problem on e.g. aarch64 hosts which never had the inotify_init syscall - it had been obsoleted by inotify_init1 before aarch64 was invented! However it does have a perfectly good glibc implementation of inotify_wait. Fix this by removing all the raw __NR_inotify_* tests, and instead check CONFIG_INOTIFY, which already tests for the glibc functionality we use. Also remove the now-pointless sys_inotify* wrappers.

2022-01-27linux-user: Remove unnecessary 'aligned' attribute from TaskStatePeter Maydell
The linux-user struct TaskState has an 'aligned(16)' attribute. When the struct was first added in commit 851e67a1b46f in 2003, there was a justification in a comment (still present in the source today): /* NOTE: we force a big alignment so that the stack stored after is aligned too */ because the final field in the struct was "uint8_t stack[0];" But that field was removed in commit 48e15fc2d in 2010 which switched us to allocating the stack and the TaskState separately. Because we allocate the structure with g_new0() rather than as a local variable, the attribute made no difference to the alignment of the structure anyway. Remove the unnecessary attribute, and the corresponding comment.

2022-01-18linux-user: don't adjust base of found holeAlex Bennée
The pgb_find_hole function goes to the trouble of taking account of both mmap_min_addr and any offset we've applied to decide the starting address of a potential hole. This is especially important for emulating 32bit ARM in a 32bit build as we have applied the offset to ensure there will be space to map the ARM_COMMPAGE bellow the main guest map (using wrapped arithmetic).
