* docs: fix references to docs/devel/atomics.rstStefano Garzarella2021-06-021-1/+1
| | | | | | | | | | | | | | | Commit 15e8699f00 ("atomics: convert to reStructuredText") converted docs/devel/atomics.txt to docs/devel/atomics.rst. We still have several references to the old file, so let's fix them with the following command: sed -i s/atomics.txt/atomics.rst/ $(git grep -l docs/devel/atomics.txt) Signed-off-by: Stefano Garzarella <sgarzare@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <philmd@redhat.com> Message-Id: <20210517151702.109066-3-sgarzare@redhat.com> Signed-off-by: Thomas Huth <thuth@redhat.com>
* tcg/aarch64: Fix tcg_out_rotlYasuo Kuwahara2021-05-271-3/+2Star
| | | | | | | | | | | The last argument of tcg_out_extr() must be in the range 0-31 if ext==0. Before the fix, when m==0 it becomes 32 and it crashes with an Illegal instruction on Apple Silicon. After the fix, it will be 0. If m is in the range 1-31, it is the same as before.

* tcg/mips: Fix SoftTLB comparison on mips backendKele Huang2021-04-051-1/+1
| | | | | | | | | | | | | | | | The addrl used to compare with SoftTLB entry should be sign-extended in common case, and it will cause constant failing in SoftTLB comparisons for the addrl whose address is over 0x80000000 on the emulation of 32-bit guest on 64-bit host. This is an important performance bug fix. Spec2000 gzip rate increase from ~45 to ~140 on Loongson 3A4000 (MIPS compatible platform).

* tcg: Fix prototypes for tcg_out_vec_op and tcg_out_opMiroslav Rezanina2021-03-178-19/+31
| | | | | | | | | | | | | | | | | There are two different versions of prototype for tcg_out_op and tcg_out_vec_op functions: 1) using const TCGArg *args and const int *const_args arguments 2) using const TCGArg args[TCG_MAX_OP_ARGS] and const int const_args[TCG_MAX_OP_ARGS] aguments. This duality causes warnings on GCC 11 and prevents build using --enable-werror. As second version provides more information, unify functions prototypes to this variant.
