* cpu: Move the softmmu tlb to CPUNegativeOffsetStateRichard Henderson2019-06-101-30/+9Star
| | | | | | | | | | | We have for some time had code within the tcg backends to handle large positive offsets from env. This move makes sure that need not happen. Indeed, we are able to assert at build time that simple offsets suffice for all hosts.

* tcg: Reduce max TB opcode countRichard Henderson2018-06-151-1/+1
| | | | | | | | | | | | | | | | | | | Also, assert that we don't overflow any of two different offsets into the TB. Both unwind and goto_tb both record a uint16_t for later use. This fixes an arm-softmmu test case utilizing NEON in which there is a TB generated that runs to 7800 opcodes, and compiles to 96k on an x86_64 host. This overflows the 16-bit offset in which we record the goto_tb reset offset. Because of that overflow, we install a jump destination that goes to neverland. Boom. With this reduced op count, the same TB compiles to about 48k for aarch64, ppc64le, and x86_64 hosts, and neither assertion fires. Cc: qemu-stable@nongnu.org Reported-by: "Jason A.

* tcg/mips: Handle large offsets from target env to tlb_tablePeter Maydell2018-04-161-7/+4Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The MIPS TCG target makes the assumption that the offset from the target env pointer to the tlb_table is less than about 64K. This used to be true, but gradual addition of features to the Arm target means that it's no longer true there. This results in the build-time assertion failing: In file included from /home/pm215/qemu/include/qemu/osdep.h:36:0, from /home/pm215/qemu/tcg/tcg.c:28: /home/pm215/qemu/tcg/mips/tcg-target.inc.c: In function ‘tcg_out_tlb_load’: /home/pm215/qemu/include/qemu/compiler.h:90:36: error: static assertion failed: "not expecting: offsetof(CPUArchState, tlb_table[NB_MMU_MODES - 1][1]) > 0x7ff0 + 0x7fff" #define QEMU_BUILD_BUG_MSG(x, msg) _Static_assert(!(x), msg) ^ /home/pm215/qemu/include/qemu/compiler.h:98:30: note: in expansion of macro ‘QEMU_BUILD_BUG_MSG’ #define QEMU_BUILD_BUG_ON(x) QEMU_BUILD_BUG_MSG(x, "not expecting: " #x) ^ /home/pm215/qemu/tcg/mips/tcg-target.inc.c:1236:9: note: in expansion of macro ‘QEMU_BUILD_BUG_ON’ QEMU_BUILD_BUG_ON(offsetof(CPUArchState, ^ /home/pm215/qemu/rules.mak:66: recipe for target 'tcg/tcg.o' failed An ideal long term approach would be to rearrange the CPU state so that the tlb_table was not so far along it, but this is tricky because it would move it from the "not cleared on CPU reset" part of the struct to the "cleared on CPU reset" part. As a simple fix for the 2.12 release, make the MIPS TCG target handle an arbitrary offset by emitting more add instructions. This will mean an extra instruction in the fastpath for TCG loads and stores for the affected guests (currently just aarch64-softmmu).
