TESTS SHALL BE VERIFIED
Preliminary information on failures (to be verified).
The following ones have problems with some combinations of modifiers:
<span class="quote">> image_gather4*
> image_load
> image_load_mip
> image_get_lod
> image_get_resinfo
> image_sample
> image_sample_b
> image_sample_b_cl
> image_sample_c
> image_sample_c_b
> image_sample_c_b_cl
> image_sample_c_cd
> image_sample_c_cl
> image_sample_c_d
> image_sample_c_l
> image_sample_c_lz
> image_sample_cl
> image_sample_l
> image_sample_lz</span >
In the following ones, vgpr_a should have 11 elements while assembler expects
4:
<span class="quote">> image_sample_d_cl_o
> image_sample_d_o
> image_sample_cd_cl_o
> image_sample_cd_o
> image_sample_c_d_cl_o
> image_sample_c_d_o
> image_sample_c_cd_cl_o
> image_sample_c_cd_o</span >
Here, vgpr_a should have 10 elements while assembler expects 4:
<span class="quote">> image_sample_d
> image_sample_cd
> image_sample_d_cl
> image_sample_cd_cl
> image_sample_c_d_cl
> image_sample_c_cd_cl</span >
Similarly, vgpr_a should have 5 elements while assembler expects 4:
<span class="quote">> image_sample_b_cl_o
> image_sample_b_o
> image_sample_c_b_cl_o
> image_sample_c_b_o
> image_sample_c_cl_o
> image_sample_c_l_o
> image_sample_c_lz_o
> image_sample_c_o
> image_sample_cl_o
> image_sample_l_o
> image_sample_lz_o
> image_sample_o</span >
The issue needs to be carefully verified/investigated.
Some GFX7 lit tests attached (both failing and passing ones). These tests are
not guaranteed to be valid, though.
Tested with r273139 (git # 4a94acfea8bfd6eb6b5809dd40f03e1fa42e673a)</pre>
