* Supply missing header guardsMarkus Armbruster2019-06-121-0/+5

* tcg: Add support for vector bitwise selectRichard Henderson2019-05-221-0/+7
| | | | | | | This operation performs d = (b & a) | (c & ~a), and is present on a majority of host vector units. Include gvec expanders. Signed-off-by: Richard Henderson <richard.henderson@linaro.org>

* tcg: Add gvec expanders for vector shift by scalarRichard Henderson2019-05-141-0/+7
| | | | | | | | | Allow expansion either via shift by scalar or by replicating the scalar for shift by vector. Signed-off-by: Richard Henderson <richard.henderson@linaro.org> --- v3: Use a private structure for do_gvec_shifts.
* tcg: Add gvec expanders for variable shiftRichard Henderson2019-05-141-0/+11
| | | | | | | | | The gvec expanders perform a modulo on the shift count. If the target requires alternate behaviour, then it cannot use the generic gvec expanders anyway, and will have to have its own custom code.

* tcg: Specify optional vector requirements with a listRichard Henderson2019-05-131-12/+12
| | | | | | | | | | | | | | | | | Replace the single opcode in .opc with a null-terminated array in .opt_opc. We still require that all opcodes be used with the same .vece. Validate the contents of this list with CONFIG_DEBUG_TCG. All tcg_gen_*_vec functions will check any list active during .fniv expansion. Swap the active list in and out as we expand other opcodes, or take control away from the front-end function. Convert all existing vector aware front ends.

* tcg: Implement tcg_gen_gvec_3i()David Hildenbrand2019-05-131-0/+24
| | | | | | | | | | | Let's add tcg_gen_gvec_3i(), similar to tcg_gen_gvec_2i(), however without introducing "gen_helper_gvec_3i *fnoi", as it isn't needed for now.

* tcg: Fix LGPL version numberThomas Huth2019-01-301-1/+1
| | | | | | | | | | | | It's either "GNU *Library* General Public version 2" or "GNU Lesser General Public version *2.1*", but there was no "version 2.0" of the "Lesser" library. So assume that version 2.1 is meant here.

* tcg: Add generic vector helpers with a scalar operandRichard Henderson2018-02-081-1/+58
| | | | | | | | | | | | Use dup to convert a non-constant scalar to a third vector. Add addition, multiplication, and logical operations with an immediate. Add addition, subtraction, multiplication, and logical operations with a non-constant scalar. Allow for the front-end to build operations in which the scalar operand comes first.

* tcg: Add generic helpers for saturating arithmeticRichard Henderson2018-02-081-0/+10
| | | | | | | | No vector ops as yet. SSE only has direct support for 8- and 16-bit saturation; handling 32- and 64-bit saturation is much more expensive. Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>

* tcg: Add generic vector ops for constant shiftsRichard Henderson2018-02-081-0/+35
| | | | | | | | | Opcodes are added for scalar and vector shifts, but considering the varied semantics of these do not expose them to the front ends. Do go ahead and provide them in case they are needed for backend expansion. Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
