| | | | | | | | | | | | | | | | | r61560 ("offsetof(type, foo.bar) is (arguably) a GCCism") introduced 16 bytes of stack overhead on 64-bit systems. Remove that overhead and cast, instead. While we're at it, restore the "waitq" name to clarify the purpose of the field. (This is one unfortunate consequence of the CC0 ccan/list.h implementation compared to the *GPL ones in glibc/urcu/linux) * variable.c (struct autoload_state): remove head field, clarify naming (autoload_reset): cast and adjust (autoload_sleep_done): ditto (rb_autoload_load): ditto git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61574 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

| | | | | | | | | | | | | | | | | | TL;DR see http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2031.htm Suppose we have: struct X { struct Y { z_t z; } y; } x; then, you _cant_ infer offsetof(struct X, y.z). The ISO C99 section 7.17 says nothing about such situation. At least clang warns this being an extension to the language (-Wextended-offsetof). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61560 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

| | | | | | | To be precise C90 says "A bit-field may have type int, unsigned int, or signed int". It is clear that char or enum are NG. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61554 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* initializer paren-string `{("str")}` is a C99ismshyouhei2018-01-021-1/+1
| | | | | | | | | | | First, `"str"` is a string constant but `("str")` is not. It is a random expression whose type happen to be const char*. Second, non-constant initializer element is forbidden in C90. Mixture of these two results in the fact that `{("str")}` is a C99ism. Just delete the parens and everything goes well. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61553 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
