2011-10-31tcg: Add bytecode generator for tcg interpreterStefan Weil
Unlike other tcg target code generators, this one does not generate machine code for some cpu. It generates machine independent bytecode which is interpreted later. This allows running QEMU on any host. Interpreted bytecode is slower than direct execution of generated machine code. Signed-off-by: Stefan Weil <sw@weilnetz.de>
2011-10-01Move GETPC from dyngen-exec.h to exec-all.hBlue Swirl
GETPC() can be used even from outside of helper code. Move the macro to a more accessible location. Avoid a compile warning from redefining it in exec.c. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2011-07-30exec.h cleanupBlue Swirl
Move softmmu_exec.h include directives from target-*/exec.h to target-*/op_helper.c. Move also various other stuff only used in op_helper.c there. Define global env in dyngen-exec.h. For i386, move wrappers for segment and FPU helpers from user-exec.c to op_helper.c. Implement raise_exception_err_env() to handle dynamic CPUState. Move the function declarations to cpu.h since they can be used outside of op_helper.c context. LM32, s390x, UniCore32: remove unused cpu_halted(), regs_to_env() and env_to_regs(). ARM: make raise_exception() static. Convert #include "exec.h" to #include "cpu.h" #include "dyngen-exec.h" and remove now unused target-*/exec.h. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2010-10-22Remove special handling of system include files (no longer needed)Stefan Weil
The formerly used dyngen code did not work with system include files like stdio.h. Tests with Linux, OSX and Win32 show that this restriction is no longer needed. So we hopefully can remove that special piece of code. This results in cleaner code and allows better use of the new GCC_FMT_ATTR macro.

2010-04-14tcp/mips: Change TCG_AREG0 (fp -> s0)Stefan Weil
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, but was no longer used and is now free for TCG_AREG0. The resulting code works for compilations without optimisation (tested with qemu mips in qemu mips on x86 host).

2009-12-05S/390 fake TCG implementationAlexander Graf
Qemu won't let us run a KVM target without having host TCG support. Well, for now we don't have any so let's implement a fake target that only stubs out everything. I tried to keep the patch as close to Uli's source as possible, so whenever he feels like it he can easily diff his version against this one.

2009-10-01Revert "Get rid of _t suffix"Anthony Liguori
In the very least, a change like this requires discussion on the list. The naming convention is goofy and it causes a massive merge problem. Something like this _must_ be presented on the list first so people can provide input and cope with it. This reverts commit 99a0949b720a0936da2052cb9a46db04ffc6db29.

this patch removes some now unused things after dyngen removal. 1. dyngen-exec.h: op_param, op _jmp and some associated macros are now unused; 2. Makefile.target: tcg-dyngen is not needed anymore 2. tcg/tcg-op.h, tcg/tcg-opc.h: gen-op.h is dead 3. tcg.c: - INDEX_op_end is now the first op - CONFIG_DYNGEN_OP is never defined 4. tcg.h: dyngen_op not needed anymore 5. exec-all.h: remove some ASM macros.
