2010-02-06tcg-i386: Implement small forward branches.Richard Henderson1-38/+79
There are places, like brcond2, where we know that the destination of a forward branch will be within 127 bytes. Add the R_386_PC8 relocation type to support this. Add a flag to tcg_out_jxx and tcg_out_brcond* to enable it. Set the flag in the brcond2 label_next branches; pass along the input flag otherwise.

Re-implement GUEST_BASE support. Offset guest ddress space by default if the guest binary contains regions below the host mmap_min_addr. Implement support for i386, x86-64 and arm hosts. Signed-off-by: Riku Voipio <riku.voipio@iki.fi> Signed-off-by: Paul Brook <paul@codesourcery.com>

2008-12-13TCG x86/x86-64: use move with zero-extend for loads/storesaurel321-0/+6
Starting with version 4.3, gcc returns the result of a function in rax/eax/ax/al instead of rax/eax, depending of the return type. As a consequence we should use a zero extend moe in TCG loads/stores. See http://gcc.gnu.org/ml/gcc/2008-01/msg00052.html for more details. A big thanks to malc who founds the problem and wrote the x86 patch.
