* use "enum ruby_tag_type" and TAG_NONE.ko12017-06-231-3/+3
| | | | | | | | | | | | | | | Return value of EXEC_TAG() is saved by "int state". Instead of "int", use "enum ruby_tag_type". First EXEC_TAG() value should be 0, so that define TAG_NONE (= 0) and use it. Some code used "status" instead of "state". To make them clear, rename them to state. We can change variable name from "state" to "tag_state", but this ticket doesn't contain it. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@59155 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* Fix build when gcc is used and the platform's libc lacks alloca().knu2012-11-091-21/+0
| | | | | | | | | | | | | | | | * include/ruby/ruby.h (alloca), eval_intern.h (alloca), gc.c (alloca): Make alloca() globally available by moving the ultimate ifdef's to ruby/ruby.h. Gcc hides its builtin alloca() when compiling with -ansi, and linking thus fails on platforms that lack their own alloca() implementation in libc, which include OpenBSD and some ports of NetBSD. We use alloca() everywhere including from within third party C extentions, so alloca() must be made globally available. [Bug #7307] * addr2line.c (alloca): Replace the alloca() part with the ultimate ifdef's. [Bug #7307] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@37571 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
