2013-10-10tcg: Add tcg-be-null.hRichard Henderson1-0/+2
This is a no-op backend data implementation, for those targets that are not currently using the load/store optimization path. This is prepatory to always requiring these functions in all backends. Signed-off-by: Richard Henderson <rth@twiddle.net>

2013-09-01tci: Remove function tcg_out64 (fix broken build)Stefan Weil1-7/+0
Commit ac26eb69a311396668809eadbf7ff4e623447d4c added tcg_out64 to tcg/tcg.c. tcg/tci/tcg-target.c already had a nearly identical implementation which is now removed to fix a compiler error.

2013-07-30tci: Fix broken build (compiler warning caused by redefined macro BIT)Stefan Weil1-3/+0
The definition of macro BIT in tci/tcg-target.c now conflicts with the definition of the same macro in includes qemu/bitops.h. This conflict was triggered by a recent change in the include chain of tcg.c (probably commit 949fc82314cc84162e64a5323764527a542421ce).

2013-04-11tci: Make tcg temporaries local to tcg_qemu_tb_execRichard Henderson1-6/+6
We're moving away from the temporaries stored in env. Make sure we can differentiate between temp stores and possibly bogus stores for extra call arguments. Move TCG_AREG0 and TCG_REG_CALL_STACK out of the way of the parameter passing registers. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off by: Stefan Weil <sw@weilnetz.de>

2013-04-11tci: Use 32-bit signed offsets to loads/storesRichard Henderson1-2/+2
Since the change to tcg_exit_req, the first insn of every TB is a load with a negative offset from env. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off by: Stefan Weil <sw@weilnetz.de>
2013-02-16qemu-log: Rename the public-facing cpu_set_log function to qemu_set_logPeter Maydell1-1/+1
Rename the public-facing function cpu_set_log to qemu_set_log. This requires us to rename the internal-only qemu_set_log() to do_qemu_set_log(). Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Andreas Färber <afaerber@suse.de> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2012-10-06tcg: remove obsolete jmp opAurelien Jarno1-4/+0
The TCG jmp operation doesn't really make sense in the QEMU context, it is unused, it is not implemented by some targets, and it is wrongly implemented by some others. This patch simply removes it.

2012-09-27tci: Fix for AREG0 free modeStefan Weil1-5/+5
Support for helper functions with 5 arguments was missing in the code generator and in the interpreter. There is no need to pass the constant TCG_AREG0 from the code generator to the interpreter. Remove that code for the INDEX_op_qemu_st* opcodes. Signed-off-by: Stefan Weil <sw@weilnetz.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2012-09-22tcg: Remove tcg_target_get_call_iarg_regs_countStefan Weil1-6/+0
The TCG targets no longer need individual implementations. Since commit 6a18ae2d2947532d5c26439548afa0481c4529f9, 'flags' is no longer used in tcg_target_get_call_iarg_regs_count. The remaining tcg_target_get_call_iarg_regs_count is trivial and only called once. Therefore the patch eliminates it completely.

2012-09-15Remove unused CONFIG_TCG_PASS_AREG0 and dead codeBlue Swirl1-4/+0
Now that CONFIG_TCG_PASS_AREG0 is enabled for all targets, remove dead code and support for !CONFIG_TCG_PASS_AREG0 case. Remove dyngen-exec.h and all references to it. Although included by hw/spapr_hcall.c, it does not seem to use it. Remove unused HELPER_CFLAGS. Signed-off-by: Blue Swirl <blauwirbel@gmail.com> Reviewed-by: Richard Henderson <rth@twiddle.net>
2012-06-24tci: don't write zero for reloc in tci_out_labelScott Wood1-1/+1
If tci_out_label is called in the context of tcg_gen_code_search_pc, we could be overwriting an already patched relocation with zero -- and not repatch it because the set_label is past search_pc, causing a QEMU crash when it tries to branch to a zero label. Not writing anything to the relocation area seems to be in line with what other backends do from the couple I looked at (x86, ppc).

2012-03-18softmmu templates: optionally pass CPUState to memory access functionsBlue Swirl1-0/+6
Optionally, make memory access helpers take a parameter for CPUState instead of relying on global env. On most targets, perform simple moves to reorder registers. On i386, switch from regparm(3) calling convention to standard stack-based version. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2011-10-31tcg: Add bytecode generator for tcg interpreterStefan Weil1-0/+906
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>
