A bulk commit of true16 support for v_cmpx_xx_f16 instructions
including:
v_cmpx_f_f16
v_cmpx_le_f16
v_cmpx_gt_f16
v_cmpx_lg_f16
v_cmpx_ge_f16
v_cmpx_o_f16
v_cmpx_u_f16
v_cmpx_nge_f16
v_cmpx_nlg_f16
v_cmpx_ngt_f16
v_cmpx_nle_f16
v_cmpx_neq_f16
v_cmpx_nlt_f16
v_cmpx_t_f16
v_cmpx_eq_f16 is not in this patch and will be added in the following
patch
Support true16 format for v_cndmask_b16 in MC and CodeGen in true16 and
fake16 flow.
Since we are replacing `v_cndmask_b16` to `v_cndmask_b16_t16/fake16`, we
have to at least update the fake16 codeGen to get codeGen test passing.
For this case, we have to update the true16 and with fake16 together,
otherwise some of the true16 tests will fail
True16 support for v_minmax/maxmin_f16(GFX11) and
v_minmax/maxmin_num_f16(GFX12).
These insts are updated at the same time since we are replacing the
`v_minmax/maxmin_f16` to `v_minmax/maxmin_fake16_f16` while
`v_minmax/maxmin_num_f16` are alias insts and share the same CodeGen
pattern.
Added a GFX12 runline in minmax.ll in fake16 flow
Support true16 format for v_fma_f16 in MC.
Since we are replacing v_fma_f16 to v_fma_f16_t16/v_fma_f16_fake16 in
Post-GFX11, have to update the CodeGen pattern for v_fma_f16_fake16 to
get CodeGen test passing. There is no pattern modified/created, but just
replacing the v_fma_f16 with fake16 format.
For GFX10+, currently null cannot be used as dst reg in instructions
that expect the dst reg to be 128b or larger (e.g., s_load_dwordx4).
This patch fixes this problem while ensuring null cannot be used as S#,
T#, or V#.
V_MAX3/MIN3_NUM_F16 are alias GFX12 instructions with V_MAX3/MIN3_F16 in
GFX11 and they should be updated together.
This fix a bug introduced in
https://github.com/llvm/llvm-project/pull/113603 such that only
V_MAX3/MIN3_F16 are replaced in true16 format. Also added GFX12 runlines
for CodeGen test
This reverts commit e0526b0780f56eede09b05a859a93626ecdc6e4d.
The `v_minmax/maxmin_f16`(GFX11) needs to be updated to t16 with
`v_minmax/maxmin_num_f16`(GFX12) together since they share the same
codegen pattern. Revert the old patch and resubmit
Support true16 format for v_minmax/maxmin_f16 in MC.
Since we are replacing `v_minmax/maxmin_f16` to `v_minmax/maxmin_f16_t16
/ v_minmax/maxmin_f16_fake16` in Post-GFX11, have to update the CodeGen
pattern for `v_minmax/maxmin_f16` to get CodeGen test passing.
Support true16 format for v_pack_b32_f16 in MC.
Since we are replacing v_alignbit_b32 to
`v_pack_b32_f16_t16/v_pack_b32_f16_fake16` in Post-GFX11, have to update
the CodeGen pattern for `v_pack_b32_f16_fake16 `to get CodeGen test
passing. There is no pattern modified/created, but just replacing the
`v_pack_b32_f16` with fake16 format.
Some of the true16 CodeGen test are impacted since `v_pack_b32_f16`
selection are removed in Post-GFX11 while `v_pack_b32_f16_t16` are not
yet supported. The CodeGen patch for `v_pack_b32_f16_t16` will be done
is the following patch.
Support true16 and fake16 format for more VOP3 instructions in MC
This patch updates the true16 and fake16 vop_profile for the following
instructions and update the asm/dasm tests:
v_mad_u16
v_mad_i16
v_med3_f16
v_med3_i16
v_med3_u16
v_max3_f16
v_max3_i16
v_max3_u16
v_min3_f16
v_min3_i16
v_min3_u16
v_med3_num_f16
This is a NFC change. Update mc test for v_and/or/xor_b16 in true16
format.
MC source change was done by previous patch and automatically enabled by
t16 pesudo
This is a NFC change. Update mc test for v_add/sub_f16 in true16 format.
MC source change was done by previous patch and automatically enabled by
