o removed -march=i586 from CONFIG.linux-x86.linux-x86
o fixed compile errors in epicsAtomicOSD.h (I didnt have the proper version of solaris for initial testing here)
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
Refactored logClientSend in libCom/logClient/logClient.c; took the code between the mutex operations and
moved it to a private method - sendLogMessageinChunks. Call this method once for the prefix (if it exists) and once
for the actual message.
Added ioCsh registration code into src/libCom/iocsh/libComRegister.c registering a command called
"iocLogPrefix" that sets this prefix.
Unit tested with and without prefixes.
Performance tested with and without prefixes - without prefix is approx the same. With prefix is about
twice the time (reflecting the two calls to sendLogMessageinChunks I think)
o refactored compilerDependencies.h into code that is compiler specific (one libCom/osi/compiler/xxx/compilerDependent.h for each comiler) and code that isnt libCom/osi/compilerDependencies.h (this is a new location and is no longer in libCom/misc).
This symbol is required to be visible on non-PowerPC (68k) vxWorks
systems for devInterruptInUseVME() to recognize interrupt vectors
that the devDisconnectInterruptVME() routine has marked as not used.
A rare race during shutdown. The contenders are the log thread
coming out of its loop and calling errlogCleanup(), and the
exitHandler signaling waitForWork.
This solution is to move cleanup completely into exitHandler,
which already waits for the log thread to exit.
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.
Build lexer and parser from libCom/Makefile.
Since libCom now includes asLib.c and asLib_lex.c we must build
antelope and flex without linking them to Com. This works because
they only need epicsTempFile anyway. However make doesn't like a
subdirectory with the same name as a target object, so the antelope
source directory is now called yacc. The two main.c files were also
renamed to avoid other build problems.
Merge asHost into Com and remove mentions in CONFIG_BASE
Lots of noise since SRCS must be renamed to Com_SRCS
The new Makefile fragments in the subdirectories are incomplete and will
not work individually. Build rules are placed in a separate RULES file.
This approach keeps the instructions for building each file local and
easier to find than in a large Makefile in the parent directory.
o Fixed race condition where win32 thread parm was not pushed onto the
list before the thread was started, and so if the thread exits very
quickly it can try to remove a non-existent thread parameter from
the list.
o This impacts only win32.
