2021-05-04target/ppc: code motion from translate_init.c.inc to gdbstub.cBruno Larsen (billionai)
All the code related to gdb has been moved from translate_init.c.inc file to the gdbstub.c file, where it makes more sense. Version 4 fixes the omission of internal.h in gdbstub, mentioned in <87sg3d2gf5.fsf@linux.ibm.com>, and the extra blank line.

2021-05-04ppc: Rename current DAWR macros and variablesRavi Bangoria
Power10 is introducing second DAWR. Use real register names (with suffix 0) from ISA for current macros and variables used by Qemu. One exception to this is KVM_REG_PPC_DAWR[X]. This is from kernel uapi header and thus not changed in kernel as well as Qemu.

2021-05-04target/ppc: Remove env->immu_idx and env->dmmu_idxRichard Henderson
We weren't recording MSR_GS in hflags, which means that BookE memory accesses were essentially random vs Guest State. Instead of adding this bit directly, record the completed mmu indexes instead. This makes it obvious that we are recording exactly the information that we need. This also means that we can stop directly recording MSR_IR.

2021-05-04target/ppc: Remove MSR_SA and MSR_AP from hflagsRichard Henderson
Nothing within the translator -- or anywhere else for that matter -- checks MSR_SA or MSR_AP on the 602. This may be a mistake. However, for the moment, we need not record these bits in hflags. This allows us to simplify HFLAGS_VSX computation by moving it to overlap with MSR_VSX.

2021-05-04target/ppc: Disconnect hflags from MSRRichard Henderson
Copying flags directly from msr has drawbacks: (1) msr bits mean different things per cpu, (2) msr has 64 bits on 64 cpus while tb->flags has only 32 bits. Create a enum to define these bits. Document the origin of each bit and validate those bits that must match MSR. This fixes the truncation of env->hflags to tb->flags, because we no longer have hflags bits set above bit 31. Most of the code in ppc_tr_init_disas_context is moved over to hreg_compute_hflags. Some of it is simple extractions from msr, some requires examining other cpu flags. Anything that is moved becomes a simple extract from hflags in ppc_tr_init_disas_context. Several existing bugs are left in ppc_tr_init_disas_context, where additional changes are required -- to be addressed in future patches. Remove a broken #if 0 block.

Keep all hflags computation in one place, as this will be especially important later. Introduce a new POWERPC_FLAG_HID0_LE bit to indicate when LE should be taken from HID0. This appears to be set if and only if POWERPC_FLAG_RTC_CLK is set, but we're not short of bits and having both names will avoid confusion. Note that this was the only user of hflags_nmsr, so we can perform a straight assignment rather than mask and set.
