This allows us to generate +TCG code instead of a call to the helper. If defined, the macro takes 1 +argument. + C semantics (aka short code) + +This allows the code generator to override the auto-generated code. In some +cases this is necessary for correct execution. We can also override for +faster emulation. For example, calling a helper for add is more expensive +than generating a TCG add operation. + +The gen_tcg.h file has any overrides. For example, we could write + #define fGEN_TCG_A2_add(GENHLPR, SHORTCODE) \ + tcg_gen_add_tl(RdV, RsV, RtV) + +The instruction semantics C code relies heavily on macros. In cases where the +C semantics are specified only with macros, we can override the default with +the short semantics option and #define the macros to generate TCG code. One +example is L2_loadw_locked: + Instruction tag L2_loadw_locked + Assembly syntax "Rd32=memw_locked(Rs32)" + Instruction semantics "{ fEA_REG(RsV); fLOAD_LOCKED(1,4,u,EA,RdV) }" + +In gen_tcg.h, we use the shortcode +#define fGEN_TCG_L2_loadw_locked(SHORTCODE) \ + SHORTCODE + +There are also cases where we brute force the TCG code generation. +Instructions with multiple definitions are examples. These require special +handling because qemu helpers can only return a single value. + +In addition to instruction semantics, we use a generator to create the decode +tree. This generation is also a two step process. The first step is to run +target/hexagon/gen_dectree_import.c to produce + /target/hexagon/iset.py +This file is imported by target/hexagon/dectree.py to produce + /target/hexagon/dectree_generated.h + +*** Key Files *** + +cpu.h + +This file contains the definition of the CPUHexagonState struct. It is the +runtime information for each thread and contains stuff like the GPR and +predicate registers. + +macros.h + +The Hexagon arch lib relies heavily on macros for the instruction semantics. +This is a great advantage for qemu because we can override them for different +purposes. You will also notice there are sometimes two definitions of a macro. +The QEMU_GENERATE variable determines whether we want the macro to generate TCG +code. If QEMU_GENERATE is not defined, we want the macro to generate vanilla +C code that will work in the helper implementation. + +translate.c + +The functions in this file generate TCG code for a translation block. Some +important functions in this file are + + gen_start_packet - initialize the data structures for packet semantics + gen_commit_packet - commit the register writes, stores, etc for a packet + decode_packet - disassemble a packet and generate code + +genptr.c +gen_tcg.h + +These files create a function for each instruction. It is mostly composed of +fGEN_TCG_ definitions followed by including tcg_funcs_generated.h. + +op_helper.c + +This file contains the implementations of all the helpers. There are a few +general purpose helpers, but most of them are generated by including +helper_funcs_generated.h. There are also several helpers used for debugging. + + +*** Packet Semantics *** + +VLIW packet semantics differ from serial semantics in that all input operands +are read, then the operations are performed, then all the results are written. +For exmaple, this packet performs a swap of registers r0 and r1 + { r0 = r1; r1 = r0 } +Note that the result is different if the instructions are executed serially. + +Packet semantics dictate that we defer any changes of state until the entire +packet is committed. We record the results of each instruction in a side data +structure, and update the visible processor state when we commit the packet. + +The data structures are divided between the runtime state and the translation +context. + +During the TCG generation (see translate.[ch]), we use the DisasContext to +track what needs to be done during packet commit. Here are the relevant +fields + + reg_log list of registers written + reg_log_idx index into ctx_reg_log + pred_log list of predicates written + pred_log_idx index into ctx_pred_log + store_width width of stores (indexed by slot) + +During runtime, the following fields in CPUHexagonState (see cpu.h) are used + + new_value new value of a given register + reg_written boolean indicating if register was written + new_pred_value new value of a predicate register + pred_written boolean indicating if predicate was written + mem_log_stores record of the stores (indexed by slot) + +*** Debugging *** + +You can turn on a lot of debugging by changing the HEX_DEBUG macro to 1 in +internal.h. This will stream a lot of information as it generates TCG and +executes the code. + +To track down nasty issues with Hexagon->TCG generation, we compare the +execution results with actual hardware running on a Hexagon Linux target. +Run qemu with the "-d cpu" option. Then, we can diff the results and figure +out where qemu and hardware behave differently. + +The stacks are located at different locations. We handle this by changing +env->stack_adjust in translate.c. First, set this to zero and run qemu. +Then, change env->stack_adjust to the difference between the two stack +locations. Then rebuild qemu and run again. That will produce a very +clean diff. + +Here are some handy places to set breakpoints + + At the call to gen_start_packet for a given PC (note that the line number + might change in the future) + br translate.c:602 if ctx->base.pc_next == 0xdeadbeef + The helper function for each instruction is named helper_, so here's + an example that will set a breakpoint at the start + br helper_A2_add + If you have the HEX_DEBUG macro set, the following will be useful + At the start of execution of a packet for a given PC + br helper_debug_start_packet if env->gpr[41] == 0xdeadbeef + At the end of execution of a packet for a given PC + br helper_debug_commit_end if env->this_PC == 0xdeadbeef + From patchwork Mon Sep 28 12:36:22 2020 Content-Type: text/plain;
