tcg: Invert the inclusion of helper.h Rather than include helper.h with N values of GEN_HELPER, include a secondary file that sets up the macros to include helper.h. This minimizes the files that must be rebuilt when changing the macros for file N. Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Richard Henderson <rth@twiddle.net>

Use #include "..." for our own headers, <...> for others Tracked down with an ugly, brittle and probably buggy Perl script. Also move includes converted to <...> up so they get included before ours where that's obviously okay.

tcg: Use memset for large vector byte replication In f47db80cc07, we handled odd-sized tail clearing for the case of hosts that have vector operations, but did not handle the case of hosts that do not have vector ops. This was ok until e2e7168a214b, which changed the encoding of simd_desc such that the odd sizes are impossible. Add memset as a tcg helper, and use that for all out-of-line byte stores to vectors. This includes, but is not limited to, the tail clearing operation in question.

plugin-gen: add module for TCG-related code 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.
