From eb326e15530dd6dca4ccbe7dbfde7bf048de813e Mon Sep 17 00:00:00 2001 From: Andrew Kelley Date: Thu, 5 Jul 2018 15:09:02 -0400 Subject: M:N threading * add std.atomic.QueueMpsc.isEmpty * make std.debug.global_allocator thread-safe * std.event.Loop: now you have to choose between - initSingleThreaded - initMultiThreaded * std.event.Loop multiplexes coroutines onto kernel threads * Remove std.event.Loop.stop. Instead the event loop run() function returns once there are no pending coroutines. * fix crash in ir.cpp for calling methods under some conditions * small progress self-hosted compiler, analyzing top level declarations * Introduce std.event.Lock for synchronizing coroutines * introduce std.event.Locked(T) for data that only 1 coroutine should modify at once. * make the self hosted compiler use multi threaded event loop * make std.heap.DirectAllocator thread-safe See #174 TODO: * call sched_getaffinity instead of hard coding thread pool size 4 * support for Windows and MacOS * #1194 * #1197 --- std/debug/index.zig | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) (limited to 'std/debug') diff --git a/std/debug/index.zig b/std/debug/index.zig index 57b2dfc300..a5e1c313f0 100644 --- a/std/debug/index.zig +++ b/std/debug/index.zig @@ -11,6 +11,11 @@ const builtin = @import("builtin"); pub const FailingAllocator = @import("failing_allocator.zig").FailingAllocator; +pub const runtime_safety = switch (builtin.mode) { + builtin.Mode.Debug, builtin.Mode.ReleaseSafe => true, + builtin.Mode.ReleaseFast, builtin.Mode.ReleaseSmall => false, +}; + /// Tries to write to stderr, unbuffered, and ignores any error returned. /// Does not append a newline. /// TODO atomic/multithread support @@ -1098,7 +1103,7 @@ fn readILeb128(in_stream: var) !i64 { /// This should only be used in temporary test programs. pub const global_allocator = &global_fixed_allocator.allocator; -var global_fixed_allocator = std.heap.FixedBufferAllocator.init(global_allocator_mem[0..]); +var global_fixed_allocator = std.heap.ThreadSafeFixedBufferAllocator.init(global_allocator_mem[0..]); var global_allocator_mem: [100 * 1024]u8 = undefined; // TODO make thread safe -- cgit v1.2.3
