2012-09-21tcg: Introduce movcondRichard Henderson1-0/+2
Implemented with setcond if the target does not provide the optional opcode. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
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).

2012-06-21qemu-log: cleanupBlue Swirl1-1/+1
Don't use global variables directly but via accessor functions. Rename globals. Convert macros to functions, add GCC format attributes. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
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>
2012-03-17w64: Fix data type of next_tb and tcg_qemu_tb_execStefan Weil1-1/+1
next_tb is the numeric value of a tcg target (= QEMU host) address. Using tcg_target_ulong instead of unsigned long shows this and makes the code portable for hosts with an unusual size of long (w64). The type cast '(long)(next_tb & ~3)' was not needed (casting unsigned long to long does not change the bits, and nor does casting long to pointer for most (= all non w64) hosts. It is removed here. Macro or function tcg_qemu_tb_exec is used to set next_tb. The function also returns next_tb. Therefore tcg_qemu_tb_exec must return a tcg_target_ulong.

2012-03-03w64: Fix data type of parameters for flush_icache_rangeStefan Weil1-1/+2
flush_icache_range takes two address parameters which must be large enough to address any address of the host. For hosts with sizeof(unsigned long) == sizeof(void *), this patch changes nothing. All currently supported hosts fall into this category. For w64 hosts, sizeof(unsigned long) is 4 while sizeof(void *) is 8, so the use of tcg_target_ulong is needed for i386 and tci (the tcg targets which work with w64).

2011-10-31tcg: Add bytecode generator for tcg interpreterStefan Weil3-0/+1196
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>
