This series adds support for the Hexagon Vector eXtensions (HVX)
These instructions are documented here
https://developer.qualcomm.com/downloads/qualcomm-hexagon-v66-hvx-programmer-s-reference-manual
Hexagon HVX is a wide vector engine with 128 byte vectors.
See patch 01 Hexagon HVX README for more information.
*** Known checkpatch issues ***
The following are known checkpatch errors in the series
target/hexagon/gen_semantics.c Suspicious ; after while (0)
tests/tcg/hexagon/hvx_misc.c Spaces around operator in macro invocation
*** Changes in v4 ***
Address feedback from Richard Henderson <richard.hender...@linaro.org>
- Use tcg_gen_gvec_orc/tcg_gen_gvec_andc
Add tests for the following opcodes
V6_pred_or
V6_pred_or_n
V6_pred_and
V6_pred_and_n
V6_pred_xor
Probe the HVX stores at the beginning of gen_commit_packet
See patches 11 (helper functions) and 12 (TCG generation)
Use tcg_constant_* instead of tcg_const_*
*** Changes in v3 ***
Clean up gen_log_vreg_write
- Remove has_vhist parameter
Remove VRegs_updated_tmp from runtime state
- Check there is exactly one tmp for vhist at TCG generation time
Remove VRegs_select from runtime state
Add test_max_temps test to tests/tcg/hexagon/hvx_misc.c
Don't pass slot to HVX helpers
*** Changes in v2 ***
Address feedback from Richard Henderson <richard.hender...@linaro.org>
- Remove zero_vector from CPUHexagonState
- Remove gather_issued from CPUHexagonState
- Remove is_gather_store_insn from DisasContext and CPUHexagonState
- Change VStoreLog.mask to a bitmap
- Change VTCMStoreLog.mask to a bitmap
- Convert future_VRegs, tmp_Vregs to allocate as-needed
- Don't cast away const
- Remove/simplify count_leading_ones_2
- Control HVX dump with CPU_DUMP_FPU
Remove HVX support from target/hexagon/gdbstub.c
- Hexagon uses lldb which will require support for qRegisterInfo in the
target-independent gdbstub. Will contribute this separately
Convert the histogram instructions to execute at the end of packet commit
- This is necessary to allocate future_VRegs as-needed
Additional tests added in tests/tcg/hexagon
Added helper overrides for several instructions
- As a result, cleaned up utility functions
Additional_cleanup
- Change TCGv_ptr to not _local_
- Remove env argument from gen_commit_hvx
