Build on Jordan's patch to allow direct branching and USE_REG_TB to co-exist. Use the power9 addpcis wherever pc-relative addrs might be handy. Merge in my power10 patches for prefixed insns. Finish up with an RFC to disable TCG_REG_TB for power9+, when pc-relative code sequences exist. I've only lightly tested this, and it seems to increase code size by a few insns per TB. It really depends on how much we end up using the constant pool. What is needed is to determine if !TCG_REG_TB helps. If it doesn't, then some of these patches could be dropped as unreachable. r~ Jordan Niethe (1): tcg/ppc: Enable direct branching tcg_out_goto_tb with TCG_REG_TB Richard Henderson (13): tcg/ppc: Untabify tcg-target.c.inc tcg: Add tcg_out_tb_start backend hook tcg/ppc: Reinterpret tb-relative to TB+4 tcg/ppc: Use ADDPCIS in tcg_out_tb_start tcg/ppc: Use ADDPCIS in tcg_out_movi_int tcg/ppc: Use ADDPCIS for the constant pool tcg/ppc: Use ADDPCIS in tcg_out_goto_tb tcg/ppc: Use PADDI in tcg_out_movi tcg/ppc: Use prefixed instructions in tcg_out_mem_long tcg/ppc: Use PLD in tcg_out_movi for constant pool tcg/ppc: Use prefixed instructions in tcg_out_dupi_vec tcg/ppc: Use PLD in tcg_out_goto_tb RFC tcg/ppc: Disable TCG_REG_TB for Power9/Power10 tcg/tcg.c | 3 + tcg/aarch64/tcg-target.c.inc | 5 + tcg/arm/tcg-target.c.inc | 5 + tcg/i386/tcg-target.c.inc | 5 + tcg/loongarch64/tcg-target.c.inc | 5 + tcg/mips/tcg-target.c.inc | 5 + tcg/ppc/tcg-target.c.inc | 280 ++++++++++++++++++++++++++----- tcg/riscv/tcg-target.c.inc | 5 + tcg/s390x/tcg-target.c.inc | 5 + tcg/sparc64/tcg-target.c.inc | 5 + tcg/tci/tcg-target.c.inc | 5 + 11 files changed, 288 insertions(+), 40 deletions(-) -- 2.34.1
