[Qemu-devel] [PATCH v5 01/21] target-arm: Abstract out load/store from a vaddr in AArch32 |
|
Date: |
Mon, 1 Jul 2013 18:35:00 +0100 |
AArch32 code (ie traditional 32 bit world) expects to be
able to pass a vaddr in a TCGv_i32. However when QEMU is
compiled with TARGET_LONG_BITS=32 the TCG load/store
functions take a TCGv_i64. Abstract out load/store with
a 32 bit vaddr so we have a place to put the zero extension
of the vaddr and the extension/truncation of the data value.
Apart from the function definitions most of this patch is
a simple s/tcg_gen_qemu_/gen_aa32_/.
