2018-10-18Add thread-local storage for POSIX-y platforms.iriri
This patch implements thread-local storage by using a segment register to store pointers to regions of memory unique to each thread. In spawned threads, this region starts above the top of the stack, while in the main thread, this region is initially statically allocated so it can be used in `__init__` functions and dynamically reallocated if it needs to grow beyond 8 slots. The api consists of 3 functions: `tlsalloc()`, which must be called from the main thread, allocates a slot and returns a key to be used with `settls(k, v)` and `gettls(k)`. Each thread inherits its tls slots from the thread that spawned it and any slot added after a given thread is spawned is not available in that thread. Adding tls regions gives threads an easy way to get their own tids, allowing us to add some basic correctness checks to the mutex code. A pointer to the base of the stack and the size of the mapping are also stored in the tls region, making it easy to support user-specified stack sizes in the future. Changes from previous version: - Fixed size of main tls static allocation. - More comments, less magic. - Fixed typo in start+osx-x64.s exit+{freebsd,linux,openbsd}-x64.s - `gettlskey` renamed to `tlsalloc`. - `key` is now `tlskey(@a#)`, improving safety. - Test is slightly less bad.

Every single conversion except for one for OS X is uint64 to int64.

2017-06-25Rename Solsock to Solsocket and make it type sockprotoMichael Forney
This constant is used as a protocol level in getsockopt/setsockopt as well as msghdr. Valid values for level include the same constants used as the protocol argument of socket (IPPROTO_*), so it needs to have the same type so the constants can be used in both functions. The rename is for consistency with the C API.
2017-06-25Use an iovec struct for readv/writevMichael Forney
This avoids the assumption that iovec and byte[:] are laid out the same way in memory.

2017-02-17Search for usefiles relative to the output.Ori Bernstein
For most uses, this is equivalent to compiler cwd, but supports out of tree builds better. It also means that builds behave the same way regardless of the directory that the compiler is run from, which is convenient for testing. This also drops support for `.use` suffixes on local uses.

This wasn't so bad. Missing: - libthread - auditing all libsys struct types.
