[Qemu-devel] [PATCH v5 03/10] tcg-mips: Support 64-bit opcodes

Bulk patch adding 64-bit opcodes into tcg_out_op. Note that mips64 is as yet neither complete nor enabled. Cc: Aurelien Jarno Cc: James Hogan Signed-off-by: Richard Henderson Signed-off-by: Jin Guojie --- tcg/mips/tcg-target.h | 41 ++ tcg/mips/tcg-target.inc.c | 322 +++

[Qemu-devel] [PATCH v5 04/10] tcg-mips: Add bswap32u and bswap64

Without the mips32r2 instructions to perform swapping, bswap is quite large, dominating the size of each reverse-endian qemu_ld/qemu_st operation. Create two subroutines in the prologue block. The subroutines require extra reserved registers (TCG_TMP[2, 3]). Using these within qemu_ld means that
