2019-01-30tcg: Fix LGPL version numberThomas Huth1-1/+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.

2019-01-28tcg: Add write_aofs to GVecGen4Richard Henderson1-8/+19
This allows writing 2 output, 3 input operations. Signed-off-by: Richard Henderson <richard.henderson@linaro.org>

2019-01-28tcg: Add logical simplifications during gvec expandRichard Henderson1-5/+30
We handle many of these during integer expansion, and the rest of them during integer optimization. Reviewed-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2018-07-09tcg: Restrict check_size_impl to multiples of the line sizeRichard Henderson1-2/+5
Normally this is automatic in the size restrictions that are placed on vector sizes coming from the implementation. However, for the legitimate size tuple [oprsz=8, maxsz=32], we need to clear the final 24 bytes of the vector register. Without this check, do_dup selects TCG_TYPE_V128 and clears only 16 bytes.

2018-03-16tcg: Add choose_vector_sizeRichard Henderson1-180/+260
This unifies 5 copies of checks for supported vector size, and in the process fixes a missing check in tcg_gen_gvec_2s. This lead to an assertion failure for 64-bit vector multiply, which is not available in the AVX instruction set.

2018-02-08tcg: Add generic vector helpers with a scalar operandRichard Henderson1-1/+360
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.

2018-02-08tcg: Add generic helpers for saturating arithmeticRichard Henderson1-0/+92
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>

2018-02-08tcg: Add generic vector ops for constant shiftsRichard Henderson1-0/+276
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>
