This package is fundamental to hugs.


A small note: From lang/hugs Makefile:

# The default -O2 breaks the interpreter producing strange internal errors
# at run time.
.if !empty(CC_VERSION:Mgcc-4*)
CFLAGS+=    -O0
.endif


This does not work as expected. A line from the compilation phase:

gcc -c -DNDEBUG=1 -Wno-error -O2 -march=ultrasparc -pipe -I/usr/local/include -I/usr/include -O0  -O2 hugs.c



-O2 -march=ultrasparc -pipe comes from mk.conf. The final -O2 is set in various configure scripts as OPTFLAGS. I set OPTFLAGS to "" in these configure scripts, but I still get the illegal instruction. Hence, this does not seem to be the core of the problem.

 How about replace "CFLAGS+=-O0" line with followings?

 BUILDLINK_TRANSFORM+= rename:-O*:-O0

 Suprisingly, that replaces nothing and results in

 cc -c -DNDEBUG=1 -O2 -mcpu=ultrasparc -pipe -I/usr/include  -O2 hugs.c


 Nevertheless, the problem on NetBSD/Sparc64 seems to sit deeper as I get illegal instruction errors even when compiling hugs with -O0. Same problem with gcc34 on NetBSD/Sparc64. Hugs compiles fine with pkgsrc on intel/linux, though.

 Oops, it should be "rename:-O[2-9]:-O0"

 Didn't work, either.

 How old is that remark in the Makefile, anway? I don't have any problems when hugs is compiled from pkgsrc on i386/linux. Maybe the transformation is not necessary on other platforms as well?


 Coming back to the netbsd/sparc64 issue. I compiled several older versions of hugs and non works on netbsd/sparc64. That problem must exist for a long time. 

 An unpatched hugs runs fine on freebsd/sparc64. So, I assume there is only a minor issue on netbsd/sparc64.

 You cannot see the replacement, it will be done internally.

 I can use without -O0 on NetBSD-5.0.2-i386.

 Hmm, then this issue is not related to gcc optimization, but NetBSD/sparc64 specific issue?

 I see on the commandline the above call to gcc (spanned by make). You don't get what you see?

 I'm not in the position to make this decision, but how about removing that transformation? The hardcoded -O2 in the configure script should then be eliminated as well.

 That's how it looks to me.

 Calls to gcc define netbsd and freebsd, respecively (-Dnetbsd or something like that). The sourcecode does not really make use of this define. So, same source code for either platform.

 You must look at ${WRKDIR}/.work.log to see what was really happened
 (compiler options will be translated/reordered).
