o changed name, OSD_ATOMIC_INLINE to EPICS_ATOMIC_INLINE
o changed supported data types, unsigned removed and int added (per reveiw at codeathon)
o added add/subtract functions (per reveiw at codeathon)
o now presuming that __sync_synchronize available all gcc 4 mingw does not provide windows mem barrier)
o consolodated on one implemention for Microsoft invarient of cmplr intrinisic or win32 by using macros to config a shared header file
o improved doc in epicsAtomic.h
o added overloaded c++ interface in namespace epics :: atomic to epicsAtomic.h
o added epicsAtomicReadMemoryBarrier and epicsAtomicWriteMemoryBarrier interface to epicsAtomic.h
o changed the implementation so that each of the functions can be individually specified for a particular compiler, os, or in the generic implementation (this is accomplished with macros)
o modified the functional and performance test so that they are based on templates so we can easily support new data types
o modified performance tests to repeat function calls and measure performance using a template
o removed function
epicsAtomicTestAndSetUIntT
o added new functions
epicsAtomicSetPtrT
epicsAtomicGetPtrT
epicsAtomicCmpAndSwapUIntT
epicsAtomicCmpAndSwapPtrT
o changed msvc intrinsics to define memory fence
o fixed mutex synchronized version so that its slow, but correct if the c++ compiler doesnt synchronized local scope static initialization
o changed most of the set/get methods to use memory barriers instead of some other primitive
o added additional tests
o added CMPLR_SRC_DIRS to ALL_SRC_DIRS, and added compiler/$CMPLR_CLASS) to INSTALL_INCLUDES in CONFIG_COMMON
o added additional compiler specific rule deciding where things are installed to in CONFIG_COMMON
o added compiler specific include install to RULES_BUILD
o changed configure/os/CONFIG.linux-x86.linux-x86 to specify minimum arch is 586 (pentium circa 1995)
o changed configure/os/CONFIG.win32-x86-cygwin.win32-x86-cygwin to specify minimum arch is 586 (pentium circa 1995)
o added epicsAtoimic facility to libCom/Makefile
o added testing and performance measurement to libCom/test/Makefile
* fix libCom exports for things which used to be built differently
* logserver needs winsock
* errlog prefix: fix warnings on win32
* fix dll imports in ioc/db
Systems that generate large numbers of errlog messages or have a slow
message listener could overwrite older messages in the message buffer
after the buffer wraps. This also corrects and annotates the test
code to describe what's being checked.
Made epicsThreadOnceTest more deterministic, replacing an
epicsThreadSleep() with epicsEventMustWait(), and added a diagnostic
message before running the thread recurse test.
Eric added a series of checks to epicsEventTest.cpp which ensure that
epicsEventSignal() only wakes one waiting thread.
This allows calc and calcout record expressions to be up to
79 characters long, and shortens the postfix buffer needed by
introducing integer literals. Also removes the length limit
for access security CALC expressions.
its own unit test program in libCom/test; changed ellFree() to take a
function pointer for the free() routine, so it can be used on Windows;
modified epicsExit and dbBkpt to use it and pass in the free routine.
