tci.c TCG_CONST err

[pwnslinger]

modifying qemu-cgc to work with qira. There are some problems which I couldn't handle it:

1. there's a linking problem error to resolving GLOBAL_* symbols defined in tci.c in linux-user/main.c. I added tci.o in linux-user/Makefile.objs which resulted in a compilation error.
   adding these lines didn't help much:

#ifndef TCG-TARGET_H
#define TCG-TARGET_H
#endif

2. One major difference in structures between the two version of QEMU is at CPUArchState and CPUState in real_target_disasm which has been patched by qira which is under my repo.

Hi! What version of qemu does qira use? Perhaps issues are because of this mismatch: it might be easier to first go to the newer qemu version, and then add the qira hooks.

Also: the "core" port layer (first commits) is fairly thin, mostly limited to the syscall emulation. Later on I tried to "force in" some optimization (making globals const, etc.), noexec protection, faithful start state, etc. Pizza also added in his changes, angr-matching, etc.
In short: it may be easier to start the port from an old commit, instead of moving all at once.
