2019-12-05coroutine/ucontext/Context.c: define __EXTENSIONS__ explicitlyYusuke Endoh
instead of ruby/config.h, per samuel's request. https://github.com/ruby/ruby/commit/dbfd4b780e3914a3f27e92c2248254452bf0fd6b#diff-7fd78c3cc8a19b7e0637502983ec26ff
2019-12-04coroutine/ucontext/Context.c: Include "ruby/config.h" for SolarisYusuke Endoh
getcontext, makecontext, and swapcontext seem to be available only when `__EXTENSION__` is defined on Solaris.
2019-11-05Fix coroutine support on win32Lars Kanis
Ruby master branch currently fails on win32 MINGW at this spec: https://github.com/ruby/spec/blob/master/core/thread/element_set_spec.rb MINGW makes use of setjmp3() implemented in MSVCRT.DLL. This function traverses the SEH list up to a terminating pointer 0xFFFFFFFF. It therefore currently segfaults on NULL. The SEH linked list must be terminated by 0xFFFFFFFF instead of NULL. This fixes the issue mentioned here: https://github.com/ruby/ruby/pull/2279#issuecomment-509508810 Notes: Merged: https://github.com/ruby/ruby/pull/2645
2019-07-19Add assertions to `coroutine_initialize_main`.Samuel Williams
2019-07-19Split assertions to check which one fails.Samuel Williams
2019-07-18Make fiber_pool more conservative on platforms with limited address space.Samuel Williams
We use COROUTINE_LIMITED_ADDRESS_SPACE to select platforms where address space is 32-bits or less. Fiber pool implementation enables more book keeping, and reduces upper limits, in order to minimise address space utilisation.
2019-07-18Stack copying implementation of coroutines.Samuel Williams
2019-07-07Add coroutine context switch for i386-mingw32Lars Kanis
It's essentially a translation of Context.asm from Intel to AT&T syntax.

2019-06-26Revert "coroutine/arm32/Context.S: save/restore the registers via stack"Yusuke Endoh
This reverts commit 6df1814c08df93bbc0b3e7a73649bcf82e126064. It caused a SEGV again: https://rubyci.org/logs/rubyci.s3.amazonaws.com/scw-9d6766/ruby-master/log/20190626T051707Z.fail.html.gz
2019-06-26Add `ucontext` coroutine implementation for generic fallback.Samuel Williams
2019-06-26coroutine/arm32/Context.S: save/restore the registers via stackYusuke Endoh
Retry of 518adcca0a and dbe232e24e
2019-06-25Revert 518adcca0a and dbe232e24eYusuke Endoh
518adcca0a: "Try using arm32 implementation for fibers." dbe232e24e: "Order of arguments might be incorrect in arm32 coroutine implementation." It seems to cause SEGV consistently on Ubuntu armv7l eabihf: https://rubyci.org/logs/rubyci.s3.amazonaws.com/scw-9d6766/ruby-master/log/20190625T081710Z.fail.html.gz https://rubyci.org/logs/rubyci.s3.amazonaws.com/scw-9d6766/ruby-master/log/20190625T111708Z.fail.html.gz

* coroutine/win32/Context.asm: old ml version 9 needs CPU directive before `.model` directive. * win32/Makefile.sub: specify object directories to separate Win32 and Win64 targets.
