* Make fiber_pool more conservative on platforms with limited address space.Samuel Williams2019-07-181-0/+1
| | | | | | | 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.
* 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
* Add `ucontext` coroutine implementation for generic fallback.Samuel Williams2019-06-261-22/+16

* 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

* Change Makefile rule for assembly to use .S rather than .ssamuel2018-11-241-0/+0
| | | | | | | It is more conventional to use compiler to pre-process and assemble the `.S` file rather than forcing Makefile to use `.s`. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@65952 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
