2020-06-02tcg: Implement gvec support for rotate by scalarRichard Henderson
No host backend support yet, but the interfaces for rotls are in place. Only implement left-rotate for now, as the only known use of vector rotate by scalar is s390x, so any right-rotate would be unused and untestable.

2020-06-02tcg: Implement gvec support for rotate by vectorRichard Henderson
No host backend support yet, but the interfaces for rotlv and rotrv are in place. Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org> --- v3: Drop the generic expansion from rot to shift; we can do better for each backend, and then this code becomes unused.
2020-06-02tcg: Implement gvec support for rotate by immediateRichard Henderson
No host backend support yet, but the interfaces for rotli are in place. Canonicalize immediate rotate to the left, based on a survey of architectures, but provide both left and right shift interfaces to the translators.

2020-05-06tcg: Fix integral argument type to tcg_gen_rot[rl]i_i{32,64}Richard Henderson
For the benefit of compatibility of function pointer types, we have standardized on int32_t and int64_t as the integral argument to tcg expanders. We converted most of them in 474b2e8f0f7, but missed the rotates.

We have this same parameter for GVecGen2i, GVecGen3, and GVecGen3i. This will make some SVE2 insns easier to parameterize. Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>

2020-05-06tcg: Add tcg_gen_gvec_dup_immRichard Henderson
Add a version of tcg_gen_dup_* that takes both immediate and a vector element size operand. This will replace the set of tcg_gen_gvec_dup{8,16,32,64}i functions that encode the element size within the function name.

2020-03-16misc: Replace zero-length arrays with flexible array member (automatic)Philippe Mathieu-Daudé
Description copied from Linux kernel commit from Gustavo A. R. Silva (see [3]): --v-- description start --v-- The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member [1], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being unadvertenly introduced [2] to the Linux codebase from now on. --^-- description end --^-- Do the similar housekeeping in the QEMU codebase (which uses C99 since commit 7be41675f7cb). All these instances of code were found with the help of the following Coccinelle script: @@ identifier s, m, a; type t, T; @@ struct s { ... t m; - T a[0]; + T a[]; }; @@ identifier s, m, a; type t, T; @@ struct s { ... t m; - T a[0]; + T a[]; } QEMU_PACKED; [1] https://gcc.gnu.org/onlinedocs/gcc/Zero-Length.html [2] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=76497732932f [3] https://git.kernel.org/pub/scm/linux/kernel/git/gustavoars/linux.git/commit/?id=17642a2fbd2c1 Inspired-by: Gustavo A.
