* coroutine/ucontext/Context.c: define __EXTENSIONS__ explicitlyYusuke Endoh2019-12-051-1/+6
| | | | | | instead of ruby/config.h, per samuel's request. https://github.com/ruby/ruby/commit/dbfd4b780e3914a3f27e92c2248254452bf0fd6b#diff-7fd78c3cc8a19b7e0637502983ec26ff
* coroutine/ucontext/Context.c: Include "ruby/config.h" for SolarisYusuke Endoh2019-12-041-0/+1
| | | | | getcontext, makecontext, and swapcontext seem to be available only when `__EXTENSION__` is defined on Solaris.
* Fix coroutine support on win32Lars Kanis2019-11-051-1/+1
| | | | | | | | | | | | | 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
* Add assertions to `coroutine_initialize_main`.Samuel Williams2019-07-191-2/+3

* Split assertions to check which one fails.Samuel Williams2019-07-191-1/+3
|
* Make fiber_pool more conservative on platforms with limited address space.Samuel Williams2019-07-185-0/+11
| | | | | | | 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.
* Stack copying implementation of coroutines.Samuel Williams2019-07-182-0/+220
|
* Add coroutine context switch for i386-mingw32Lars Kanis2019-07-071-0/+47
| | | | | It's essentially a translation of Context.asm from Intel to AT&T syntax.
* Restore updated implementation of arm32 coroutine code, but prefer ucontext.Samuel Williams2019-06-262-4/+12

* Revert "coroutine/arm32/Context.S: save/restore the registers via stack"Yusuke Endoh2019-06-262-5/+4
| | | | | | | 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

* Revert 518adcca0a and dbe232e24eYusuke Endoh2019-06-251-6/+2
| | | | | | | | | | 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

* Fix for coroutine/win32/Context.objnobu2018-11-281-0/+1
| | | | | | | | | | | * 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. Win32 rule was overridden by Win64 rule and just ignored. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@66059 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* Change Makefile rule for assembly to use .S rather than .ssamuel2018-11-245-0/+0
