branches/zip:
Simplify the compile time checks by splittig them into 5 independent checks:
* Whether GCC atomics are available
* Whether pthread_t can be used by GCC atomics
* Whether Solaris libc atomics are available
* Whether pthread_t can be used by Solaris libs atomics
* Checking the size of pthread_t

branches/zip:
Add the check for GCC atomics to ut0auxconf* (copied from plug.in) because
we no longer rely on MySQL's HAVE_GCC_ATOMIC_BUILTINS.

Update comment to reflect reality.

branches/zip:
Move the check whether to include ut0auxconf.h before everything because
we are now even checking for GCC atomics, we relied on MySQL to define
this macro before.
r5869 | vasil | 2009-09-12 03:33:11 -0500 (Sat, 12 Sep 2009) | 15 lines
branches/zip:
Include ut0auxconf.h only if none of the macros it would define is defined.
The check when to include this header was outdated from the time when there
was only one macro involved.
Move the atomics checks that are in univ.i outside of
#if windows ... #else ... #endif
This simplifies the code and removes some duplicates like defining
HAVE_ATOMIC_BUILTINS if HAVE_WINDOWS_ATOMICS is defined in both branches.
Do not define the same macro HAVE_ATOMIC_PTHREAD_T for different events.
Instead define HAVE_IB_ATOMIC_PTHREAD_T_GCC and
HAVE_IB_ATOMIC_PTHREAD_T_SOLARIS.

branches/zip:
Define HAVE_ATOMIC_BUILTINS and INNODB_RW_LOCKS_USE_ATOMICS in os0sync.h
instead of in univ.i. The code expects os_*() macros to be present if
HAVE_ATOMIC_BUILTINS and INNODB_RW_LOCKS_USE_ATOMICS are defined. So define
them next to defining the os_*() macros.

branches/zip:
Rename HAVE_SOLARIS_ATOMICS to HAVE_IB_SOLARIS_ATOMICS and
IB_HAVE_PAUSE_INSTRUCTION to HAVE_IB_PAUSE_INSTRUCTION so they
all follow the same HAVE_IB_* convention.
r5872 | vasil | 2009-09-12 04:35:17 -0500 (Sat, 12 Sep 2009) | 5 lines
branches/zip:
Explicitly include os0sync.h to the places where HAVE_ATOMIC_BUILTINS and
INNODB_RW_LOCKS_USE_ATOMICS are used to avoid potential problems.

/* Do not remove this file even though it is empty.

This file is included in univ.i and will cause compilation failure
|
|
if not present.
|
|
A custom checks have been added in the generated
|
|
storage/innobase/Makefile.in that is shipped with the InnoDB Plugin
|
|
source archive. These checks eventually define some macros and put
|
|
them in this file.
|
|
This is a hack that has been developed in order to deploy new compile
|
|
time checks without the need to regenerate the ./configure script that is
|
|
distributed in the MySQL 5.1 official source archives.
|
|
If by any chance Makefile.in and ./configure are regenerated and thus
|
|
the hack from Makefile.in wiped away then the "real" checks from plug.in
|
|
will take over.
