tcg arm/mips/ia64: add a comment about retranslation and caches

Add a comment about cache coherency and retranslation, so that people
developping 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't
due to a stupid typo. Fix it.

tcg: Make some tcg-target.c routines static.

Both tcg_target_init and tcg_target_qemu_prologue
are 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_64
to 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 compilations
without optimisation, because the compiler makes heavy use
of 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 guest
physical 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 support
partial retranslation.

tcg: Disambiguate qemu_ld32u with 32-bit and 64-bit outputs.

Some targets (e.g. Alpha and MIPS64) need to keep 32-bit operands
sign-extended in 64-bit registers (regardless of the "real" sign
of the operand). For that, we need to be able to distinguish
between a 32-bit load with a 32-bit result and a 32-bit load with...

tcg/mips: fix crash in tcg_out_qemu_ld()

The address register is overriden when it corresponds to v0 and the fast
path is taken, which leads to a crash. Fix that by using the a0 register
instead.

tcg: initial mips support

Based on a patch from Arnaud Patard (Rtp) <>

A few words about design choices:
  • Two registers, at and t0, are reserved for TCG internal use. They are
    useful for bswap and 64-bit ops.
  • Most ops supports a constant argument with value 0, which is actually...
