Bruce Momjian 511db38ace Update copyright for 2009. 2009-01-01 17:24:05 +00:00
Peter Eisentraut 79d306c84a Support for Sun Studio compiler on Linux 
This basically takes some build system code that was previously labeled
"Solaris" and ties it to the compiler rather than the operating system.

Bruce Momjian 9098ab9e32 Update copyrights in source tree to 2008. 2008-01-01 19:46:01 +00:00
Tom Lane c8b7e811f3 Apparently icc doesn't always define __ICC, and it's more correct to 
check for __INTEL_COMPILER.  Per report from Dirk Tilger.
Not back-patched since I don't fully trust it yet ...

Tom Lane 9f6f51d5d4 Hmm, so evidently _check_lock and _clear_lock take an argument of type 
int not unsigned int.  Third try to get grebe building without warnings...

Tom Lane 5aaf09ac46 So our reward for including <sys/atomic_op.h> seems to be a bunch of 
nattering about casting away volatile.  Losers.
 2007-07-16 04:57:57 +00:00
Tom Lane 057d5c421f On AIX, include <sys/atomic_op.h> so that the functions we use for 
TAS support are properly declared.

Tom Lane c7464720a3 tas() support for Renesas' M32R processor. Kazuhiro Inaoka 2007-05-04 15:20:52 +00:00
Bruce Momjian 29dccf5fe0 Update CVS HEAD for 2007 copyright. Back branches are typically not 
back-stamped for this.

Bruce Momjian 399a36a75d Prepare code to be built by MSVC: 
o  remove many WIN32_CLIENT_ONLY defines
	o  add WIN32_ONLY_COMPILER define
	o  add 3rd argument to open() for portability
	o  add include/port/win32_msvc directory for
	   system includes

Bruce Momjian 291724dfa8 Solaris tas() uses 'int' now.

Tom Lane cc7eab38dd Recognize __ppc64__, which seems to be Apple's spelling of the predefined 
symbol for PPC64 hardware.  I hadn't known that Apple supported PPC64 at
all, but darn if there aren't 64-bit variant libraries in OS X as well
as support in their gcc.

Tom Lane a72ee09090 Add infrastructure for making spins_per_delay variable depending on 
whether we seem to be running in a uniprocessor or multiprocessor.
The adjustment rules could probably still use further tweaking, but
I'm convinced this should be a win overall.
 2005-10-11 20:41:32 +00:00
Tom Lane 9907b9775b Don't use a non-locked pre-test of the spinlock on x86_64 machines. 
The pre-test has been shown to be a big loss on Opterons and at best a
wash on EM64T.

Tom Lane 2d03390945 Sigh, looks like you need '.set mips2' before you can access MIPS 
SYNC instruction.
 2005-08-29 00:41:34 +00:00
Tom Lane 7319ab9a59 Add a SYNC instruction to the S_UNLOCK sequence for MIPS. 2005-08-28 18:26:01 +00:00
Tom Lane 5824d02155 Get the MIPS assembler syntax right. Also add a separate sync command; 
the reference I consulted yesterday said SC does a SYNC, but apparently
this is not true on newer MIPS processors, so be safe.
 2005-08-27 16:22:48 +00:00
Tom Lane 846319db3f Another try at the inlined MIPS spinlock code. Can't test this myself, 
but for sure it's not any more broken than the prior version.
 2005-08-26 22:04:42 +00:00
Tom Lane 396526d8c3 Adjust m68k spinlock code to avoid duplicate in-line and not-in-line 
definitions on recent Linux systems, per Martin Pitt.
 2005-08-26 14:47:35 +00:00
Tom Lane 1a33436224 Replace out-of-line tas() assembly code for MIPS with a properly 
constrained GCC inline version.  Thiemo Seufer, by way of Martin Pitt.
 2005-08-25 17:17:10 +00:00

PostgreSQL Daemon 2ff501590b Tag appropriate files for rc3 
Also performed an initial run through of upgrading our Copyright date to
extend to 2005 ... first run here was very simple ... change everything
where: grep 1996-2004 && the word 'Copyright' ... scanned through the
generated list with 'less' first, and after, to make sure that I only
picked up the right entries ...

Neil Conway f629583f94 Document what the "rep; nop" x86 assembler sequence is actually equivalent 
to, and what it is intended to do.
 2004-10-06 23:41:59 +00:00
Tom Lane 682598139e Get rid of /*-inside-comment warning. My fault. 2004-09-24 01:48:43 +00:00
Tom Lane 409b38f514 Fix TAS assembly stuff for Solaris/386. (I'm not in a position to 
actually test this, but it couldn't be broken any worse than it was...)
 2004-09-24 00:21:32 +00:00
Tom Lane 5042985fb4 Add s_lock support for HPUX on IA64, per Shinji Teragaito. 2004-09-02 17:10:58 +00:00
Tom Lane 17364edce6 slock_t must be int not char for MIPS. 7.4 got this right, but the 
info was apparently mistranscribed in s_lock code rearrangement.
 2004-08-30 22:49:07 +00:00
Bruce Momjian da9a8649d8 Update copyright to 2004. 2004-08-29 04:13:13 +00:00
Tom Lane 1098677482 Adjust TAS assembly as per recent discussions: use "+m"(*lock) everywhere 
to reference the spinlock variable, and specify "memory" as a clobber
operand to be sure gcc does not try to keep shared-memory values in
registers across a spinlock acquisition.  Also tighten the S/390 asm
sequence, which was apparently written with only minimal study of the
gcc asm documentation.  I have personally tested i386, ia64, ppc, hppa,
and s390 variants --- there is some small chance that I broke the others,
but I doubt it.
 2004-06-19 23:02:32 +00:00
Tom Lane 037e2fcf8f Must test for __hppa__ as well as __hppa to make linux-hppa happy. 2004-01-03 05:47:44 +00:00
Tom Lane f8eed65dfb Improve spinlock code for recent x86 processors: insert a PAUSE 
instruction in the s_lock() wait loop, and use test before test-and-set
in TAS() macro to avoid unnecessary bus traffic.  Patch from Manfred
Spraul, reworked a bit by Tom.
 2003-12-27 20:58:58 +00:00
Tom Lane afb09b5a31 Use inlined TAS() on PA-RISC, if we are compiling with gcc. 
Patch inspired by original submission from ViSolve.
 2003-12-23 22:15:07 +00:00
Tom Lane 9adaf64da3 Mop-up for HAS_TEST_AND_SET refactoring. Un-break two or three platforms 
that were broken, try to make layout of s_lock.h entries consistent,
use HAVE_SPINLOCKS in preference to HAS_TEST_AND_SET everywhere outside
s_lock.h itself.
 2003-12-23 18:13:17 +00:00
Bruce Momjian caf6e9d2dd Have configure --without-spinlocks actually not use spinlock code, even 
if supported by the cpu.
 2003-12-23 03:52:10 +00:00
Bruce Momjian 69f2e9b0fc Move slock_t typdefs into s_lock.h from include/port files for 
centralization and easier maintanence.
 2003-12-23 03:31:30 +00:00
Bruce Momjian 887b5a7be0 Remove NEED_I386_TAS_ASM and just test for compiler defines. 2003-12-23 00:32:06 +00:00
Bruce Momjian b731d04101 Test for __alpha and __alpha__. 2003-12-22 23:36:38 +00:00
PostgreSQL Daemon 55b113257c make sure the $Id tags are converted to $PostgreSQL as well ... 2003-11-29 22:41:33 +00:00
