2021-03-17tcg/tci: Push opcode emit into each caseRichard Henderson1-3/+32
We're about to split out bytecode output into helpers, but we can't do that one at a time if tcg_out_op_t is being done outside of the switch. Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2021-03-17tcg/tci: Implement the disassembler properlyRichard Henderson1-0/+283
Actually print arguments as opposed to simply the opcodes and, uselessly, the argument counts. Reuse all of the helpers developed as part of the interpreter. Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2021-03-17tcg/tci: Remove tci_disasRichard Henderson2-12/+0
This function is unused. It's not even the disassembler, which is print_insn_tci, located in disas/tci.c. Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2021-03-17tcg/tci: Hoist op_size checking into tci_args_*Richard Henderson1-14/+73
This performs the size check while reading the arguments, which means that we don't have to arrange for it to be done after the operation. Which tidies all of the branches. Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>

2021-03-17tcg/tci: Reduce qemu_ld/st TCGMemOpIdx operand to 32-bitsRichard Henderson2-6/+6
We are currently using the "natural" size routine, which uses 64-bits on a 64-bit host. The TCGMemOpIdx operand has 11 bits, so we can safely reduce to 32-bits. Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2021-03-17tcg/tci: Clean up deposit operationsRichard Henderson3-28/+30
Use the correct set of asserts during code generation. We do not require the first input to overlap the output; the existing interpreter already supported that. Split out tci_args_rrrbb in the translator. Use the deposit32/64 functions rather than inline expansion.

Convert to indirect jumps, as it's less complicated. Then we just have a pointer to the tb address at which the chain is stored, from which we read. Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2021-03-17tcg/tci: Reuse tci_args_l for exit_tbRichard Henderson2-10/+5
Do not emit a uint64_t, but a tcg_target_ulong, aka uintptr_t. This reduces the size of the constant on 32-bit hosts. The assert for label != NULL has to be removed because that is a valid value for exit_tb.

2021-03-17tcg/tci: Split out tci_args_rrsRichard Henderson1-44/+67
Begin splitting out functions that do pure argument decode, without actually loading values from the register set. This means that decoding need not concern itself between input and output registers. We can assert that the register number is in range during decode, so that it is safe to simply dereference from regs[] later.
