2017-09-07tcg/ppc: Use constant pool for moviRichard Henderson
Signed-off-by: Richard Henderson <rth@twiddle.net>
2017-09-07tcg: Rearrange ldst label trackingRichard Henderson
Dispense with TCGBackendData, as it has never been used for more than holding a single pointer. Use a define in the cpu/tcg-target.h to signal requirement for TCGLabelQemuLdst, so that we can drop the no-op tcg-be-null.h stubs. Rename tcg-be-ldst.h to tcg-ldst.inc.c.

2017-09-07tcg: Move USE_DIRECT_JUMP discriminator to tcg/cpu/tcg-target.hRichard Henderson
Replace the USE_DIRECT_JUMP ifdef with a TCG_TARGET_HAS_direct_jump boolean test. Replace the tb_set_jmp_target1 ifdef with an unconditional function tb_target_set_jmp_target. While we're touching all backends, add a parameter for tb->tc_ptr; we're going to need it shortly for some backends. Move tb_set_jmp_target and tb_add_jump from exec-all.h to cpu-exec.c. This opens the possibility for TCG_TARGET_HAS_direct_jump to be a runtime decision -- based on host cpu capabilities, the size of code_gen_buffer, or a future debugging switch.

2017-06-05tcg/ppc: Implement goto_ptrRichard Henderson
Signed-off-by: Richard Henderson <rth@twiddle.net>
2017-06-05tcg: Introduce goto_ptr opcode and tcg_gen_lookup_and_goto_ptrEmilio G. Cota
Instead of exporting goto_ptr directly to TCG frontends, export tcg_gen_lookup_and_goto_ptr(), which calls goto_ptr with the pointer returned by the lookup_tb_ptr() helper. This is the only use case we have for goto_ptr and lookup_tb_ptr, so having this function is very convenient. Furthermore, it trivially allows us to avoid calling the lookup helper if goto_ptr is not implemented by the backend. Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Emilio G.

2016-07-12tcg: Clean up tcg-target.h header guardsMarkus Armbruster
These use guard symbols like TCG_TARGET_$target. scripts/clean-header-guards.pl doesn't like them because they don't match their file name (they should, to make guard collisions less likely).

2015-08-24tcg: rename trunc_shr_i32 into trunc_shr_i64_i32Aurelien Jarno
The op is sometimes named trunc_shr_i32 and sometimes trunc_shr_i64_i32, and the name in the README doesn't match the name offered to the frontends.

2015-06-03tcg: add TCG_TARGET_TLB_DISPLACEMENT_BITSPaolo Bonzini
This will be used to size the TLB when more than 8 MMU modes are used by the target. Limitations come from the limited size of the immediate fields (which sometimes, as in the case of Aarch64, extend to instructions that shift the immediate).
