Replace config-time define HOST_WORDS_BIGENDIAN

2022-04-06T08:50:37+00:00

Replace a config-time define with a compile time condition define (compatible with clang and gcc) that must be declared prior to its usage. This avoids having a global configure time define, but also prevents from bad usage, if the config header wasn't included before. This can help to make some code independent from qemu too. gcc supports __BYTE_ORDER__ from about 4.6 and clang from 3.2.

tcg/mips: Support unaligned access for softmmu

2022-02-08T21:55:02+00:00

We can use the routines just added for user-only to emit unaligned accesses in softmmu mode too. Tested-by: Jiaxun Yang Reviewed-by: Jiaxun Yang Reviewed-by: Philippe Mathieu-Daudé Signed-off-by: Richard Henderson

tcg/mips: Support unaligned access for user-only

2022-02-08T21:55:02+00:00

This is kinda sorta the opposite of the other tcg hosts, where we get (normal) alignment checks for free with host SIGBUS and need to add code to support unaligned accesses. Fortunately, the ISA contains pairs of instructions that are used to implement unaligned memory accesses. Use them.

exec/memop: Adding signedness to quad definitions

2022-01-08T05:46:10+00:00

Renaming defines for quad in their various forms so that their signedness is now explicit. Done using git grep as suggested by Philippe, with a bit of hand edition to keep assignments aligned.

tcg: Rename TCGMemOpIdx to MemOpIdx

2021-10-05T23:53:17+00:00

We're about to move this out of tcg.h, so rename it as we did when moving MemOp. Reviewed-by: Alistair Francis Reviewed-by: Philippe Mathieu-Daudé Signed-off-by: Richard Henderson

tcg: Expand MO_SIZE to 3 bits

2021-10-05T23:53:17+00:00

We have lacked expressive support for memory sizes larger than 64-bits for a while. Fixing that requires adjustment to several points where we used this for array indexing, and two places that develop -Wswitch warnings after the change.

tcg/mips: Unset TCG_TARGET_HAS_direct_jump

2021-09-22T02:36:44+00:00

Only use indirect jumps. Finish weaning away from the unique alignment requirements for code_gen_buffer. Reviewed-by: Philippe Mathieu-Daudé Signed-off-by: Richard Henderson

tcg/mips: Allow JAL to be out of range in tcg_out_bswap_subr

2021-09-22T02:36:44+00:00

Weaning off of unique alignment requirements, so allow JAL to not reach the target. TCG_TMP1 is always available for use as a scratch because it is clobbered by the subroutine being called. Reviewed-by: Philippe Mathieu-Daudé Signed-off-by: Richard Henderson

tcg/mips: Drop inline markers
