target/sh4: Fix TB_FLAG_UNALIGN

2022-10-04T19:33:05+00:00

The value previously chosen overlaps GUSA_MASK. Rename all DELAY_SLOT_* and GUSA_* defines to emphasize that they are included in TB_FLAGs. Add aliases for the FPSCR and SR bits that are included in TB_FLAGS, so that we don't accidentally reassign those bits.

linux-user: Provide MADV_* definitions

2022-09-27T07:30:09+00:00

Provide MADV_* definitions using target_mman.h header, similar to what kernel does. Most architectures use the same values, with the exception of alpha and hppa.

Leave TARGET_ALIGNED_ONLY set, but use the new CPUState flag to set MO_UNALN for the instructions that the kernel handles in the unaligned trap. The Linux kernel does not handle all memory operations: no floating-point and no MAC.

linux-user: Split out do_prctl and subroutines

2022-01-06T10:40:52+00:00

Since the prctl constants are supposed to be generic, supply any that are not provided by the host. Split out subroutines for PR_GET_FP_MODE, PR_SET_FP_MODE, PR_GET_VL, PR_SET_VL, PR_RESET_KEYS, PR_SET_TAGGED_ADDR_CTRL, PR_GET_TAGGED_ADDR_CTRL. Return EINVAL for guests that do not support these options rather than pass them on to the host.
