The resulting cc is only dependent on the result and the carry-out. Carry-out and borrow-out are inverses, so are trivially converted. With tcg ops, it is easier to compute borrow-out than carry-out, so save result and borrow-out rather than the inputs. Borrow-out for 64-bit inputs is had via tcg_gen_sub2_i64 directly into cc_src. Borrow-out for 32-bit inputs is had via extraction from a normal 64-bit sub (with zero-extended inputs).

2020-12-19migration: Replace migration's JSON writer by the general oneMarkus Armbruster9-18/+18
Commit 8118f0950f "migration: Append JSON description of migration stream" needs a JSON writer. The existing qobject_to_json() wasn't a good fit, because it requires building a QObject to convert. Instead, migration got its very own JSON writer, in commit 190c882ce2 "QJSON: Add JSON writer". It tacitly limits numbers to int64_t, and strings contents to characters that don't need escaping, unlike qobject_to_json(). The previous commit factored the JSON writer out of qobject_to_json(). Replace migration's JSON writer by it.

2020-12-19qapi: Use QAPI_LIST_PREPEND() where possibleEric Blake6-46/+9
Anywhere we create a list of just one item or by prepending items (typically because order doesn't matter), we can use QAPI_LIST_PREPEND(). But places where we must keep the list in order by appending remain open-coded until later patches. Note that as a side effect, this also performs a cleanup of two minor issues in qga/commands-posix.c: the old code was performing new = g_malloc0(sizeof(*ret)); which 1) is confusing because you have to verify whether 'new' and 'ret' are variables with the same type, and 2) would conflict with C++ compilation (not an actual problem for this file, but makes copy-and-paste harder).

2020-12-18linux-user/sparc: Handle tstate in sparc64_get/set_context()Peter Maydell2-8/+21
Correctly implement save/restore of the tstate field in sparc64_get_context() and sparc64_set_context(): * Don't use the CWP value from the guest in set_context * Construct and save a tstate value rather than leaving it as zero in get_context To do this we factor out the "calculate TSTATE value from CPU state" code from sparc_cpu_do_interrupt() into its own sparc64_tstate() function; that in turn requires us to move some of the function prototypes out from inside a CPU_NO_IO_DEFS ifdef guard.

2020-12-18linux-user/sparc: Correct sparc64_get/set_context() FPU handlingPeter Maydell1-1/+3
The handling of the FPU state in sparc64_get_context() and sparc64_set_context() is not the same as what the kernel actually does: we unconditionally read and write the FP registers and the FSR, GSR and FPRS, but the kernel logic is more complicated: * in get_context the kernel has code for saving FPU registers, but it is hidden inside an "if (fenab) condition and the fenab flag is always set to 0 (inside an "#if 1" which has been in the kernel for over 15 years). So the effect is that the FPU state part is always written as zeroes. * in set_context the kernel looks at the fenab field in the structure from the guest, and only restores the state if it is set; it also looks at the structure's FPRS to see whether either the upper or lower or both halves of the register file have valid data. Bring our implementations into line with the kernel: * in get_context: - clear the entire target_ucontext at the top of the function (as the kernel does) - then don't write the FPU state, so those fields remain zero - this fixes Coverity issue CID 1432305 by deleting the code it was complaining about * in set_context: - check the fenab and the fpsr to decide which parts of the FPU data to restore, if any - instead of setting the FPU registers by doing two 32-bit loads and filling in the .upper and .lower parts of the CPU_Double union separately, just do a 64-bit load of the whole register at once. This fixes Coverity issue CID 1432303 because we now access the dregs[] part of the mcfpu_fregs union rather than the sregs[] part (which is not large enough to actually cover the whole of the data, so we were accessing off the end of sregs[]) We change both functions in a single commit to avoid potentially breaking bisection.

2020-12-17target/riscv: Fix the bug of HLVX/HLV/HSVYifei Jiang1-1/+2
We found that the hypervisor virtual-machine load and store instructions, included HLVX/HLV/HSV, couldn't access guest userspace memory. In the riscv-privileged spec, HLVX/HLV/HSV is defined as follow: "As usual when V=1, two-stage address translation is applied, and the HS-level sstatus.SUM is ignored." But get_physical_address() doesn't ignore sstatus.SUM, when HLVX/HLV/HSV accesses guest userspace memory. So this patch fixes it.

2020-12-17linux-user/elfload: Introduce MIPS GET_FEATURE_REG_EQU() macroPhilippe Mathieu-Daudé1-0/+1
ISA features are usually denoted in read-only bits from CPU registers. Add the GET_FEATURE_REG_EQU() macro which checks if a CPU register has bits set to a specific value. Use the macro to check the 'Architecture Revision' level of the Config0 register, which is '2' when the Release 6 ISA is implemented.

2020-12-16i386: move TCG cpu class initialization to tcg/Claudio Fontana19-148/+238
to do this, we need to take code out of cpu.c and helper.c, and also move some prototypes from cpu.h, for code that is needed in tcg/xxx_helper.c, and which in turn is part of the callbacks registered by the class initialization. Therefore, do some shuffling of the parts of cpu.h that are only relevant for tcg/, and put them in tcg/helper-tcg.h For FT0 and similar macros, put them in tcg/fpu-helper.c since they are used only there.
