2024-04-26accel/tcg: Rename load-extract/store-insert headers using .h.inc suffixPhilippe Mathieu-Daudé2-0/+0
Since commit 139c1837db ("meson: rename included C source files to .c.inc"), QEMU standard procedure for included C files is to use *.c.inc. Besides, since commit 6a0057aa22 ("docs/devel: make a statement about includes") this is documented in the Coding Style: If you do use template header files they should be named with the ``.c.inc`` or ``.h.inc`` suffix to make it clear they are being included for expansion. Therefore rename 'store-insert-al16.h' as 'store-insert-al16.h.inc' and 'load-extract-al16-al8.h' as 'load-extract-al16-al8.h.inc'.

2023-11-13host/include/generic/host/atomic128: Fix compilation problem with Clang 17Thomas Huth2-2/+2
When compiling QEMU with Clang 17 on a s390x, the compilation fails: In file included from ../accel/tcg/cputlb.c:32: In file included from /root/qemu/include/exec/helper-proto-common.h:10: In file included from /root/qemu/include/qemu/atomic128.h:62: /root/qemu/host/include/generic/host/atomic128-ldst.h:68:15: error: __sync builtin operation MUST have natural alignment (consider using __ atomic).

[-Werror,-Wsync-alignment] 36 | r.i = __sync_val_compare_and_swap_16(ptr_align, c.i, n.i); | ^ 2 errors generated. It's arguably a bug in Clang since we already use __builtin_assume_aligned() to tell the compiler that the pointer is properly aligned. But according to https://github.com/llvm/llvm-project/issues/69146 it seems like the Clang folks don't see an easy fix on their side and recommend to use a type declared with __attribute__((aligned(16))) to work around this problem.

2023-05-23qemu/atomic128: Split atomic16_readRichard Henderson1-8/+23
Create both atomic16_read_ro and atomic16_read_rw. Previously we pretended that we had atomic16_read in system mode, because we "know" that all ram is always writable to the host. Now, expose read-only and read-write versions all of the time. For aarch64, do not fall back to __atomic_read_16 even if supported by the compiler, to work around a clang bug.
