[Qemu-devel] [PATCH V2 0/1] ARM aarch64 TCG tlb fast lookup

[Jani Kokkonen <Jani.Kokkonen@huawei.com>]

This patch implements the TCG tlb fast lookup in 
tcg_out_qemu_ld/st for the aarch64 TCG target.  
Supports also CONFIG_QEMU_LDST_OPTIMIZATION.

Tested running on a x86-64 physical machine running Foundation v8,
running a linux 3.2.0 minimal host system based on linaro v8
image build 0.8.4423 for user space.

Tested guests: arm v5, PPC64, sparc, i386 linux test images.
Also tested on x86-64/linux built with buildroot.

Changes in v2:
-Fix whitespace and indentation
-Pass mem_index into tcg_out_tlb_read() and calculate tlb_offset inside  
 tcg_out_tlb_read() 
-Add comments in tcg_out_tlb_read() 
-Change parameter type from int to TCGREg for data_reg and addr_reg parameters
 in add_qemu_ldst_label()
-Use extended register for tcg_out_cmp() in tcg_out_tlb_read() only if needed
