   For some reason, alpha was not defined on some platforms, I think.

   There was some goofy problem in the past with this flag, and making it
   happen only in certain places helped some problem.  I don't really
   remember the cause at this point.  CVS log may show it.

2. Linux templates

   Peter Eisentraut <peter_e@gmx.net> — 2000-07-01T21:24:20Z

   We've got 7 linux templates all doing the same thing, and one more
   (s390) coming up. How about putting them all into one?
   
   Any news on why linux_alpha defines CPU=alpha, which
   is used in backend/storage/ipc/Makefile:
   
   ifeq ($(CPU),alpha)
   ifeq ($(CC), gcc)
   CFLAGS+= -fno-inline
   endif
   ifeq ($(CC), egcs)
   CFLAGS+= -fno-inline
   endif
   endif
   
   (Certainly a compiler bug -- what's the latest on that?)
   
   and in backend/utils/adt/Makefile:
   
   ifeq ($(CPU),alpha)
   ifeq ($(CC), gcc)
   CFLAGS+= -mieee
   endif
   ifeq ($(CC), egcs)
   CFLAGS+= -mieee
   endif
   endif
   
   (Reading the documentation on this, it seems that we should perhaps
   compile the entire source with -mieee, rather than having certain parts
   work more "correctly" than others.)

3. Re: [PORTS] Re: Linux templates

   Uncle George <gatgul@voicenet.com> — 2000-07-01T23:35:12Z

   Actually, from compiling your latest version , the CPU= equate did a strange
   thing. I expected CPU=alpha, but it placed instead CPU=alpha_ev56 ( or
   something like that ) the ev56 is a particular alpha processor ( like
   pentium II, III, 486 ... ).
   no-inline for the alpha/cc compiler was necessary because the in-lining of
   assembler code ( the  test and set code ) did not work without getting lock
   failures.
   The -mieee flag tells the cc compiler to wait for FP traps to maybe happen.
   Without this flag the FP errors will not be ieee754(?) comforment, and
   therefor not produce the same results as the i386 port.  But u pay for this
   feature ( u gotta wait for the FP processing to complete before going on ).
   At one point, having the -mieee switch on ment that the compiler would
   insert waits, even where no FP processing has occured. I do not know of the
   current state of the -mieee switch ( ie more carefull where stalls are
   inserted ). I limit my usage of -mieee to only the modules that do FP work.
