Subject: [PATCH v4 00/31] Base for adding PowerPC 64-bit instructions
Date: Wed, 12 May 2021 15:54:10 -0300	[thread overview]
Message-ID: <20210512185441.3619828-1-matheus.ferst@eldorado.org.br> (raw)

From: Matheus Ferst <matheus.ferst@eldorado.org.br>

This series provides the basic infrastructure for adding the new 32/64-bit
instructions in Power ISA 3.1 to target/ppc.

v4:
- Rebase on ppc-for-6.1;
- Fold do_ldst_D and do_ldst_X;
- Add tcg_const_tl, used to share do_ldst_D and do_ldst_X code;
- Unfold prefixed and non-prefixed loads/stores/addi to let non-prefixed insns use the non-prefixed formats;
- PNOP invalid suffixes;
- setbc/setbcr/stnbc/setnbcr implemented;
- cfuged/vcfuged implemented;
- addpcis moved to decodetree.

v3:
- More changes for decodetree.
- Cleanup exception/is_jmp logic to the point exception is removed.
- Fold in Luis' isa check for prefixed insn support.
- Share trans_* between prefixed and non-prefixed instructions.
- Use macros to minimize the trans_* boilerplate.
- Fix decode mistake for STHX/STHXU.

v2:
- Store current pc in ctx instead of insn_size
- Use separate decode files for 32- and 64-bit instructions
- Improvements to the exception/is_jmp logic
- Use translator_loop_temp_check()
- Moved logic to prevent translation from crossing page boundaries
- Additional instructions using decodetree: addis, pnop, loads/stores
- Added check for prefixed insn support in cpu flags

Matheus Ferst (6):
  target/ppc: Introduce gen_icount_io_start
  TCG: add tcg_constant_tl
  target/ppc: Implement setbc/setbcr/stnbc/setnbcr instructions
