* When clang builds libc it may insert calls to __aeabi_* functions. Normallyandrew2013-02-121-0/+19
| | | | | | | | | | this is not a problem as they are resolved by libgcc. The exception is for the __aeabi_mem* functions. These call back into libc to the appropriate function. This causes issues for static binaries as we only link against libc once so there is no way for it to call into libgcc and back. The fix for this is to include these symbols in libc but keep them hidden so binaries use the libgcc version.

* Implement guest vcpu pinning using 'pthread_setaffinity_np(3)'.neel2013-02-112-30/+0
| | | | | | | | | | | | | | Prior to this change pinning was implemented via an ioctl (VM_SET_PINNING) that called 'sched_bind()' on behalf of the user thread. The ULE implementation of 'sched_bind()' bumps up 'td_pinned' which in turn runs afoul of the assertion '(td_pinned == 0)' in userret(). Using the cpuset affinity to implement pinning of the vcpu threads works with both 4BSD and ULE schedulers and has the happy side-effect of getting rid of a bunch of code in vmm.ko.

Dont build ASTMatchers with Rewriter disabled and StaticAnalyzer when it's disabled. Without all those three, the clang binary shrinks (x86_64) from ~36MB to ~32MB (unstripped). To disable these clang components, and get a smaller clang binary built and installed, set WITHOUT_CLANG_FULL in src.conf(5). During the initial stages of buildworld, those extra components are already disabled automatically, to save some build time. MFC after: 1 week

Conversely, use NULL as write-callback when opened in read-only mode. - Implement the handling of the ``b'' character in the mode argument. A binary buffer differs from a text buffer (default mode if ``b'' is omitted) in that NULL bytes are never appended to writes and that the "buffer data length" equals to the size of the buffer. - Remove shall from the man page. Use indicative instead. Also, specify that the ``b'' flag does not conform with POSIX but is supported by glibc. - Update the regression test so that the ``b'' functionality and the "buffer data length" concepts are tested. - Minor style(9) corrections.

Note: This changes the ABI for libcxxrt, but libcxxrt is currently only in -STABLE for testing and is not used by anything unless explicitly enabled by the end user. No default compiler configurations use it. libc++ will need to be recompiled after this change. make buildworld will do this automatically, but make in lib/libc++ will not necessarily work unless the new libcxxrt is installed first.
