| | | | | | | | | | | | | | | | | | | | | Update license to strptime(3) implementation. Our strptime(3) implementation was the base for the illumos implementation and after contacting the author, Kevin Rudy stated the code is under a 2-Clause BSD License [1] After reviewing our local changes to the file in question, the FreeBSD Foundation has agreed that their contributions to this file are not required to carry clause 3 or 4 so the file can be relicensed as in Illumos [2].

| | | | | | | | | | | | | | | | | | - Replace malloc+memset with calloc. - iconv_open(3): initialise ci_ilseq_invalid field of _citrus_iconv_shared struct after allocation with malloc. - iconvlist(3): reduce a memory leak by copying strings only once. - iconv(1): - Make invalids variable local to do_conv such that it prints the number of invalid characters of the current file instead of an accumulated value. - Make do_conv return an error when invalid characters have been found. Return EXIT_FAILURE from main if any file contained invalid characters. This matches the behaviour of GNU iconv. - Mark usage with __dead2 attribute. - Make the long_options array const.

| | | | | | | | | In some scenarios, when generating llvm/clang .inc.h files, multiple source files could be passed to tblgen or clang-tblgen, leading to a "Too many positional arguments specified" error message. Fix this by replacing the too-generic ${.ALLSRC} sources with explicit paths. Reported by: rysto32@gmail.com, rodrigc

| | | | | | | | | | | | | | | | | | | | | | | | | Add virtualized XSAVE support to bhyve which permits guests to use XSAVE and XSAVE-enabled features like AVX. - Store a per-cpu guest xcr0 register and handle xsetbv VM exits by emulating the instruction. - Only expose XSAVE to guests if XSAVE is enabled in the host. Only expose a subset of XSAVE features currently supported by the guest and for which the proper emulation of xsetbv is known. Currently this includes X87, SSE, AVX, AVX-512, and Intel MPX. - Add support for injecting hardware exceptions into the guest and use this to trigger exceptions in the guest for invalid xsetbv operations instead of potentially faulting in the host. - Queue pending exceptions in the 'struct vcpu' instead of directly updating the processor-specific VMCS or VMCB. The pending exception will be delivered right before entering the guest. - Rename the unused ioctl VM_INJECT_EVENT to VM_INJECT_EXCEPTION and restrict it to only deliver x86 hardware exceptions. This new ioctl is now used to inject a protection fault when the guest accesses an unimplemented MSR. - Expose a subset of known-safe features from leaf 0 of the structured extended features to guests if they are supported on the host including RDFSBASE/RDGSBASE, BMI1/2, AVX2, AVX-512, HLE, ERMS, and RTM. Aside from AVX-512, these features are all new instructions available for use in ring 3 with no additional hypervisor changes needed.

Without this gcc generates an incorrect assembly file that doesn't allow for vfp instructions. Only build the vfp/softfp switching code on armv6 as we don't support vfp on anything earlier than this. This should fix the armeb and arm builds when using gcc. Add an optimised version of the float and double helper functions.

| | | | | | | | | | | | | | | | | Use the new -d option that was added to tblgen between llvm/clang 3.3 and 3.4 to generate dependency files for the '.inc.h' files generated from .td files, and .sinclude those dependency files in clang.build.mk. This will make future incremental builds of lib/clang and usr.bin/clang work correctly, whenever any of the .td files get modified. Note that this will not fix any problems with incremental builds from *before* this revision, since there will not yet be any generated dependency files. A quick workaround is to run the following: find /usr/obj -type f -name '*.inc.h' | xargs rm and then a regular incremental buildworld (e.g. with -DNO_CLEAN).

Requested by: jhibbits MFC 262611: Pull in r196874 from upstream llvm trunk: Fix a crash that occurs when PWD is invalid. MCJIT needs to be able to run in hostile environments, even when PWD is invalid. There's no need to crash MCJIT in this case. The obvious fix is to simply leave MCContext's CompilationDir empty when PWD can't be determined. This way, MCJIT clients, and other clients that link with LLVM don't need a valid working directory. If we do want to guarantee valid CompilationDir, that should be done only for clients of getCompilationDir(). This is as simple as checking for an empty string. The only current use of getCompilationDir is EmitGenDwarfInfo, which won't conceivably run with an invalid working dir. However, in the purely hypothetically and untestable case that this happens, the AT_comp_dir will be omitted from the compilation_unit DIE. This should help fix assertions occurring with ports-mgmt/tinderbox, when it is using jails, and sometimes invalidates clang's current working directory.
