Experimental fork of QEMU with video encoding patches https://git.openslx.org/bwlp/qemu.git/atom/target/microblaze/op_helper.c?h=spice_video_codecs 2022-02-21T09:18:06+00:00 2022-02-21T09:18:06+00:00 Philippe Mathieu-Daudé 2022-02-07T08:27:56+00:00 urn:sha1:cd6174843b0896c9e57176159b38ecba45bade0e Many files use "qemu/log.h" declarations but neglect to include it (they inherit it via "exec/exec-all.h"). "exec/exec-all.h" is a core component and shouldn't be used that way. Move the "qemu/log.h" inclusion locally to each unit requiring it.

Store the ESS for the unaligned data access in the iflags for the insn, so that it can be found during unwind. Tested-by: Edgar E. Iglesias <edgar.iglesias@xilinx.com> Reviewed-by: Edgar E.
