2023-01-16tcg: add perfmap and jitdumpIlya Leoshkevich
Add ability to dump /tmp/perf-<pid>.map and jit-<pid>.dump. The first one allows the perf tool to map samples to each individual translation block. The second one adds the ability to resolve symbol names, line numbers and inspect JITed code. Example of use: perf record qemu-x86_64 -perfmap ./a.out perf report or perf record -k 1 qemu-x86_64 -jitdump ./a.out DEBUGINFOD_URLS= perf inject -j -i perf.data -o perf.data.jitted perf report -i perf.data.jitted Co-developed-by: Vanderson M. do Rosario <vandersonmr2@gmail.com> Co-developed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Ilya Leoshkevich <iii@linux.ibm.com> Message-Id: <20230112152013.125680-4-iii@linux.ibm.com> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>

When guest_base != 0, we were not coordinating the usage of TCG_REG_TMP0 as base properly, leading to a previous zero-extend of the input address being discarded. Shuffle the alignment check to the front, because that does not depend on the zero-extend, and it keeps the register usage clear. Set base after each step of the address arithmetic instead of before. Return the base register used from tcg_out_tlb_load, so as to keep that register choice localized to that function.

2023-01-05tcg: Reorg function callsRichard Henderson
Pre-compute the function call layout for each helper at startup. Drop TCG_CALL_DUMMY_ARG, as we no longer need to leave gaps in the op->args[] array. This allows several places to stop checking for NULL TCGTemp, to which TCG_CALL_DUMMY_ARG mapped. For tcg_gen_callN, loop over the arguments once. Allocate the TCGOp for the call early but delay emitting it, collecting arguments first. This allows the argument processing loop to emit code for extensions and have them sequenced before the call. For tcg_reg_alloc_call, loop over the arguments in reverse order, which allows stack slots to be filled first naturally. Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
