2012-10-23Rename target_phys_addr_t to hwaddrAvi Kivity
target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are reserved) and its purpose doesn't match the name (most target_phys_addr_t addresses are not target specific). Replace it with a finger-friendly, standards conformant hwaddr. Outstanding patchsets can be fixed up with the command git rebase -i --exec 'find -name "*.[ch]" | xargs s/target_phys_addr_t/hwaddr/g' origin Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-10-20target-sparc: fix FMOVr instructionAurelien Jarno
Like the MOVr instruction, the FMOVr instruction has the condition encoded between bits 10 and 12. Cc: Blue Swirl <blauwirbel@gmail.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-20target-sparc: Remove cpu_tmp0 as a globalRichard Henderson
Subroutines do their own local temporary management. Within disas_sparc_insn we limit the existance of the variable to OP=2 insns, and delay initialization as late as is reasonable for the specific XOP. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-20target-sparc: Make cpu_dst local to OP=2 insnsRichard Henderson
And initialize it such that it (may) write directly to rd. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-20target-sparc: Only use cpu_dst for eventual writes to a gprRichard Henderson
Use cpu_tmp0 for other stuff, like Write Priv Register. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-20target-sparc: Remove last uses of cpu_tmp64Richard Henderson
Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-20target-sparc: Remove cpu_tmp64 use from softint insnsRichard Henderson
The use of "tl" functions and a tmp64 is logically incompatible. Use cpu_tmp0 instead. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-20target-sparc: Don't use a temporary for gen_dest_fpr_DRichard Henderson
In all cases we don't have write-before-read problems. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-20target-sparc: Remove usage of cpu_tmp64 from most helper functionsRichard Henderson
Use a locally allocated temporary instead. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-20target-sparc: Tidy ldfsr, stfsrRichard Henderson
Remove the last uses of cpu_tmp32. Unify the code between sparc64 and sparc32 by using the proper "tl" functions. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-20target-sparc: Avoid cpu_tmp32 in Write Priv RegisterRichard Henderson
No need to copy to a temporary to store 32 bits. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-20target-sparc: Avoid cpu_tmp32 in Read Priv RegisterRichard Henderson
We don't need another temporary here. Load directly into the register we want to set. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-20target-sparc: Use get_temp_i32 in gen_dest_fpr_FRichard Henderson

Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-20target-sparc: Cleanup cpu_src[12] allocationRichard Henderson
Now that get_temp_tl is used for get_src[12], we don't need to pre-allocate these temporaries. Fallout from this is moving some assignments around cas/casx to avoid uninitialized variable warnings. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-20target-sparc: Finish conversion to gen_load_gprRichard Henderson
All users of gen_movl_{reg_TN,TN_reg} are removed. At the same time, make cpu_val a local variable for load/store disassembly. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-20target-sparc: Convert swap to gen_load/store_gprRichard Henderson

2012-10-20target-sparc: Convert asi helpers to gen_*_gprRichard Henderson
Push the DisasContext down so that we can use gen_load/store_gpr in sode gen_ldda_asi, gen_stda_ast, gen_cas_asi, gen_casx_asi. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-20target-sparc: Use gen_load_gpr in get_src[12]Richard Henderson
This means we can avoid the incoming temporary, though the cleanup of the existing temporaries is not performed in this patch. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-20target-sparc: Conversion to gen_*_gpr, part 1Richard Henderson

2012-10-20target-sparc: Add gen_load/store/dest_gprRichard Henderson
Infrastructure to be used to clean up handling of temporaries. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-13target-sparc: Don't compute full flags value so oftenRichard Henderson
Avoid speculatively computing flags before every potentially trapping operation and instead do the flags computation when a trap actually occurs. This gives approximately 30% speedup in emulation. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-13target-sparc: Avoid unnecessary local temporariesRichard Henderson
Now that save_state never ends a BB, we don't need to copy values into local temps around it. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2012-10-07target-sparc: Optimize conditionals using SUBCCRichard Henderson
Aka "normal" comparisons. We now have the infrastructure to pass back non-boolean results from gen_compare. This will automatically get used by both branches and conditional moves. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-07target-sparc: Fall through from not-taken trapRichard Henderson
Now that we've cleaned up global temporary allocation, we can continue translating the fallthru path of a conditional trap. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-07target-sparc: Cleanup "global" temporary allocationRichard Henderson
There are 6 temporaries that disas_sparc_insn relies on having been allocated. Now that they are no longer referenced across branches, they need not be allocated as local temps. Move the allocation/free of these temporaries to make it clear that they are local to the translation of a single insn.

2012-10-07target-sparc: Move taddcctv and tsubcctv out of lineRichard Henderson
The branches around the exception are maintaining an otherwise unnecessary use of local temps for the cpu destination. Note that gen_op_t{add,sub}_cc were identical to gen_op_{add,sub}_cc. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-07target-sparc: Tidy TccRichard Henderson
Share more code between unconditional and conditional paths. Move the computation of the trap number into the conditional BB; avoid using temporaries that have gone out of scope (cpu_tmp32) or rely on local temps (cpu_dst). Fully fold the exception number when the trap number is %g0+imm. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2012-10-07target-sparc: Introduce DisasCompare and functions to generate itRichard Henderson
For the moment gen_cond et al retain their existing interface, using setcond to turn a (potential) comparison back into a boolean. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

No need for ifdefs when the log mask does just as well. No need to print pc/npc when we're dumping the whole cpu state. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-07target-sparc: Tidy cpu_dump_stateRichard Henderson
