2018-10-24target/mips: Make R5900 DMULT[U], DDIV[U], LL[D] and SC[D] user onlyFredrik Noring
The Linux kernel traps certain reserved instruction exceptions to emulate the corresponding instructions. QEMU plays the role of the kernel in user mode, so those traps are emulated by accepting the instructions. This change adds the function check_insn_opc_user_only to signal a reserved instruction exception for flagged CPUs in QEMU system mode. The MIPS III instructions DMULT[U], DDIV[U], LL[D] and SC[D] are not implemented in R5900 hardware. They are trapped and emulated by the Linux kernel and, accordingly, therefore QEMU user only instructions.

The three-operand MULT and MULTU are the only R5900-specific instructions emitted by GCC 7.3. The R5900 also implements the three- operand MADD and MADDU instructions, but they are omitted in QEMU for now since they are absent in programs compiled by current GCC versions. Likewise, the R5900-specific pipeline 1 instruction variants MULT1, MULTU1, DIV1, DIVU1, MADD1, MADDU1, MFHI1, MFLO1, MTHI1 and MTLO1 are omitted here as well.

The R5900 implements the 64-bit MIPS III instruction set except DMULT, DMULTU, DDIV, DDIVU, LL, SC, LLD and SCD. The MIPS IV instructions MOVN, MOVZ and PREF are implemented. It has the R5900-specific three-operand instructions MADD, MADDU, MULT and MULTU as well as pipeline 1 versions MULT1, MULTU1, DIV1, DIVU1, MADD1, MADDU1, MFHI1, MFLO1, MTHI1 and MTLO1. A set of 93 128-bit multimedia instructions specific to the R5900 is also implemented. The Toshiba TX System RISC TX79 Core Architecture manual: https://wiki.qemu.org/File:C790.pdf describes the C790 processor that is a follow-up to the R5900. There are a few notable differences in that the R5900 FPU - is not IEEE 754-1985 compliant, - does not implement double format, and - its machine code is nonstandard.

2018-10-23osdep: Work around MinGW assertRichard Henderson
In several places we use assert(FEATURE), and assume that if FEATURE is disabled, all following code is removed as unreachable. Which allows us to compile-out functions that are only present with FEATURE, and have a link-time failure if the functions remain used. MinGW does not mark its internal function _assert() as noreturn, so the compiler cannot see when code is unreachable, which leads to link errors for this host that are not present elsewhere. The current build-time failure concerns 62823083b8a2, but I remember having seen this same error before. Fix it once and for all for MinGW.

2018-10-21slirp: Add sanity check for str option lengthFam Zheng
When user provides a long domainname or hostname that doesn't fit in the DHCP packet, we mustn't overflow the response packet buffer. Instead, report errors, following the g_warning() in the slirp->vdnssearch branch. Also check the strlen against 256 when initializing slirp, which limit is also from the protocol where one byte represents the string length. This gives an early error before the warning which is harder to notice or diagnose.

2018-10-19block: Clean up bdrv_img_create()'s error reportingMarkus Armbruster
bdrv_img_create() takes an Error ** argument and uses it in the conventional way, except for one place: when qemu_opts_do_parse() fails, it first reports its error to stderr or the HMP monitor with error_report_err(), then error_setg()'s a generic error. When the caller reports that second error similarly, this produces two consecutive error messages on stderr or the HMP monitor. When the caller does something else with it, such as send it via QMP, the first error still goes to stderr or the HMP monitor. Fortunately, no such caller exists. Simply use the first error as is. Update expected output of qemu-iotest 049 accordingly.

2018-10-19vl: Simplify call of parse_name()Markus Armbruster
main() checks for parse_name() failure even though it can't actually fail. That's okay. Simplify it to check by passing &error_fatal, like the other users of qemu_opts_foreach().

2018-10-19blockdev: Convert drive_new() to ErrorMarkus Armbruster
Calling error_report() from within a function that takes an Error ** argument is suspicious. drive_new() calls error_report() even though it can run within drive_init_func(), which takes an Error ** argument. drive_init_func()'s caller main(), via qemu_opts_foreach(), is fine with it, but clean it up anyway: * Convert drive_new() to Error * Update add_init_drive() to report the error received from drive_new() * Make main() pass &error_fatal through qemu_opts_foreach(), drive_init_func() to drive_new() * Make default_drive() pass &error_abort through qemu_opts_foreach(), drive_init_func() to drive_new() Cc: Kevin Wolf <kwolf@redhat.com> Cc: Max Reitz <mreitz@redhat.com> Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Reviewed-by: Max Reitz <mreitz@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <philmd@redhat.com> Message-Id: <20181017082702.5581-34-armbru@redhat.com>
2018-10-19vl: Assert drive_new() does not fail in default_drive()Markus Armbruster
If creating (empty) default drives fails, it's a bug. Therefore, assert() is more appropriate than exit(1).
