2020-06-02tcg: Improve move ops in liveness_pass_2Richard Henderson
If the output of the move is dead, then the last use is in the store. If we propagate the input to the store, then we can remove the move opcode entirely. Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2020-06-02tcg/ppc: Implement INDEX_op_rot[lr]v_vecRichard Henderson
We already had support for rotlv, using a target-specific opcode; convert to use the generic opcode. Handle rotrv via simple negation. Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2020-06-02tcg/aarch64: Implement INDEX_op_rotl{i,v}_vecRichard Henderson
For immediate rotate , we can implement this in two instructions, using SLI. For variable rotate, the oddness of aarch64 right-shift- as-negative-left-shift means a backend-specific expansion works best. Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2020-06-02tcg/i386: Implement INDEX_op_rotl{i,s,v}_vecRichard Henderson
For immediates, we must continue the special casing of 8-bit elements. The other element sizes and shift types are trivially implemented with shifts. Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
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.

A given RISU testcase for SVE can produce tcg-op-vec.c:511: do_shifti: Assertion `i >= 0 && i < (8 << vece)' failed. because expand_vec_sari gave a shift count of 32 to a MO_32 vector shift. In 44f1441dbe1, we changed from direct expansion of vector opcodes to re-use of the tcg expanders.

2019-12-18Add use of RCU for qemu_logfile.Robert Foley
This now allows changing the logfile while logging is active, and also solves the issue of a seg fault while changing the logfile. Any read access to the qemu_logfile handle will use the rcu_read_lock()/unlock() around the use of the handle. To fetch the handle we will use atomic_rcu_read(). We also in many cases do a check for validity of the logfile handle before using it to deal with the case where the file is closed and set to NULL. The cases where we write to the qemu_logfile will use atomic_rcu_set(). Writers will also use call_rcu() with a newly added qemu_logfile_free function for freeing/closing when readers have finished.

2019-11-11tcg/LICENSE: Remove out of date claim about TCG subdirectory licensingPeter Maydell
Since 2008 the tcg/LICENSE file has not changed: it claims that everything under tcg/ is BSD-licensed. This is not true and hasn't been true for years: in 2013 we accepted the tcg/aarch64 target code under a GPLv2-or-later license statement. We also have generic vector optimisation code under the LGPL2.1-or-later, and the TCI backend is GPLv2-or-later. Further, many of the files are not BSD licensed but MIT licensed. We don't really consider the tcg subdirectory to be a distinct part of QEMU anyway. Remove the LICENSE file, since claiming false information about the license of the code is confusing.

2019-10-28plugin-gen: add module for TCG-related codeEmilio G. Cota
We first inject empty instrumentation from translator_loop. After translation, we go through the plugins to see what they want to register for, filling in the empty instrumentation. If if turns out that some instrumentation remains unused, we remove it. This approach supports the following features: - Inlining TCG code for simple operations. Note that we do not export TCG ops to plugins. Instead, we give them a C API to insert inlined ops. So far we only support adding an immediate to a u64, e.g. to count events. - "Direct" callbacks. These are callbacks that do not go via a helper. Instead, the helper is defined at run-time, so that the plugin code is directly called from TCG. This makes direct callbacks as efficient as possible; they are therefore used for very frequent events, e.g. memory callbacks. - Passing the host address to memory callbacks. Most of this is implemented in a later patch though. - Instrumentation of memory accesses performed from helpers. See the corresponding comment, as well as a later patch. Signed-off-by: Emilio G.

The VSX instruction set instructions include double-word loads and stores, double-word load and splat, double-word permute, and bit select. All of which require multiple operations in the Altivec instruction set. Because the VSX registers map %vsr32 to %vr0, and we have no current intention or need to use vector registers outside %vr0-%vr19, force on the {ax,bx,cx,tx} bits within the added VSX insns so that we don't have to otherwise modify the VR[TABC] macros.
