I've been trying to install patches 19..28 on a DECStation 3100 and it's
failing TEST in op.eval #7 and op.search #40,41,42. I went back and
recompiled [t]*{toke,eval}.c with -Olimit set to 3000 as CC had complained in
these modules (there may have been others that I also recompiled). It still
didn't help. I gather from catching the tail end of a discussion here that
all is not well with the optimizer in the DECStation 3100 camp.
Could someone fill me in on what needs to be done to get the newer version
working? I'd be really grateful.
Thanks,
Pat.

I'd be really grateful. You have a couple of options: 1) Use GCC with my patches installed and optimize it (works with -O -fstrength-reduce -finline-functions -fomit-frame-pointer and -mgpOPT options). Gcc 1.38 will contain the fixes needed, but not the patches that allow you to debug local variables. I now use perl patchlevel 28 as a test suite. 2) Don't optimize. I don't remember offhand which are the modules you shouldn't optimize with the 1.31 and 2.00 MIPS compilers. 3) Install the 2.10 MIPS compilers that are rumored to fix these problems, and are supposed to be on the latest Ultrix 4.00 patch tape. I have not seen the 2.10 compiler suite, so this is second hand information. This is certainly a candidate for a FAQ list (and probably the generic dbm doesn't work with GCC 1.xx on a Sparc). -- Michael Meissner email: meissner@osf.org phone: 617-621-8861 Open Software Foundation, 11 Cambridge Center, Cambridge, MA, 02142 Do apple growers tell their kids money doesn't grow on bushes?

Undefining d_volatile in config.sh may also help. Larry
