2014-02-25T07:00:10+00:00

* configure.in (PACKED_STRUCT): check VC pragma too, and make
  function-style macro.

* win32/Makefile.sub (PACKED_STRUCT): enable with VC.

time: only use packed struct on x86*

2014-02-24T11:10:11+00:00

* configure.in: define PACKED_STRUCT_UNALIGNED for x86*
* timev.h (struct vtm): use PACKED_STRUCT_UNALIGNED
* time.c (struct time_object): ditto
  [Bug #9558] non-x86 cannot safely access unaligned addresses

time: rearrange+pack vtm and time_object structs

2014-02-24T03:38:14+00:00

struct time_object shrinks from 88 to 46 bytes on my 64-bit system.

* configure.in: use -Wno-packed-bitfield-compat for GCC 4.4+
  use __attribute__((packed)) if available
* timev.h: shrink and pack struct vtm
* time.c: pack struct time_object and adjust/introduce helpers

timev.h: move time_t stuffs

2013-03-30T21:08:36+00:00

* timev.h (TYPEOF_TIMEVAL_TV_SEC, unsigned_time_t): move from time.c.

* thread.c: use definitions in timev.h.

git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@40011 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* timev.h (TIME_SCALE): defined as 1000000000.

2009-08-29T19:06:29+00:00

  (struct vtm): subsec is replaced by subsecx.
  subsec * TIME_SCALE == subsecx.

* time.c: avoid rational in most cases.
  (struct time_object): timev is replaced by timexv.
  timev * TIME_SCALE == timexv.

* time.c: remove time_t restriction from Time class.

2009-04-21T14:56:59+00:00

* timev.h: new file to define struct vtm.

* strftime.c: format struct vtm instead of struct tm.

* ext/syck/rubyext.c (mktime_do): don't use time_t;
