tcg arm/mips/ia64: add a comment about retranslation and caches
Add a comment about cache coherency and retranslation, so that peopledevelopping new targets based on existing ones are warned of the issue.

tcg/mips: fix branch target change during code retranslation
TCG on MIPS was trying to avoid changing the branch offset, but didn'tdue to a stupid typo. Fix it.

tcg: Make some tcg-target.c routines static.
Both tcg_target_init and tcg_target_qemu_prologueare unused outside of tcg.c.

tcg: Add TYPE parameter to tcg_out_mov.
Mirror tcg_out_movi in having a TYPE parameter. This allows x86_64to perform the move at the proper width, which may elide a REX prefix.
Introduce a TCG_TYPE_REG enumerator to represent the "native width" of the host register, and to distinguish the usage from "pointer data"...
tcp/mips: Change TCG_AREG0 (fp -> s0)
Register fp (frame pointer) is a bad choice for compilationswithout optimisation, because the compiler makes heavy useof this register (so the resulting code crashes).
Register s0 had been used for TCG_AREG1 in earlier releases,...

Split TLB addend and target_phys_addr_t
Historically the qemu tlb "addend" field was used for both RAM and IO accesses,so needed to be able to hold both host addresses (unsigned long) and guestphysical addresses (target_phys_addr_t). However since the introduction of...
tcg/mips: fix branch offset during retranslation
Branch offsets should only be overwritten during relocation, to supportpartial retranslation.
