Bug ID: 28170
Summary: [mc][gfx7] Some VOP3 F32 insns (v_cubeid_f32,
v_fma_f32 etc) -- negative inline constants not
supported
Product: libraries
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: Backend: AMDGPU
Assignee: artem.tama...@amd.com
Reporter: artem.tama...@amd.com
CC: llvm-bugs@lists.llvm.org, nikolay.haus...@amd.com
Classification: Unclassified
The following instructions have issues with negative inline constants:
> v_cubeid_f32
> v_cubema_f32
> v_cubesc_f32
> v_cubetc_f32
> v_div_fixup_f32
> v_div_fmas_f32
> v_fma_f32
> v_mad_f32
> v_mad_legacy_f32
> v_max3_f32
> v_med3_f32
> v_min3_f32
> v_mullit_f32
Number of failing lit1 tests (-search=simple) = 4173.
I am almost sure that issue appears for other sub-targets as well, e.g. gfx8
Tested with r272673 (git # da10a460d7c98278561225fda90855b303675f35)
