-- snip --

Same source but build with "-O" only works without crashing in such strange
areas...
Setting "component" to "Build Config" due lack of another component which says
"compiler errors/issues"...

CC'ing rich.burridge@Sun.COM to forward this to the compiler team...

Any updates here ?

richb:
Does this still happen with newer versions of Sun Workshop 6 Update 2 ?

Comment 2

No idea. We build with Forte 6 Update 1.

Comment 3

I did a new test with WS6U2FCS+patches + 2001-11-20-08-trunk - I am still
getting this crash, even when I try it with --enable-optimize="-fast -xO4
-xarch=generic"

Looking at the options used when the "-fast" macro is given... I assume it's
"-dalign" which causes the trouble here:
-- snip --
-dalign (SPARC platform) Generates double-word load and
        store instructions whenever possible for improved
        performance.  This option assumes that all
        double-typed data are double-word-aligned.  If you
        compile one unit with -dalign, compile all units
        of a program with -dalign, or you  might get unex-
        pected results.
-- snip --

Everything else used in the "-fast" macro seems to be OK ("-xO5" should be
replaced by "-xO4" as -"xO5" always required a up-to-date patched compiler...).

Some tests related to the "-fast" option:
Works:
--enable-optimize="-xO4 -xtarget=generic -xbuiltin=%all -xlibmil"
Crash with SIGBUS:
"-fsimple=2 -ftrap=%none -xO4 -xtarget=generic -xbuiltin=%all -xlibmil"

I'll try to narrow this further down ...

--enable-optimize="-ftrap=%none -xO4 -xtarget=generic -xbuiltin=%all -xlibmil"
works, too.
I am going to blame "-fsimple=2" for this issue, but I have to test another
build with "-dalign -xO4" ...

Comment 6

--enable-optimize="-dalign -xO4 -xtarget=generic -xbuiltin=%all -xlibmil" works
on my box, it seems that "-fsimple=2" causes this issue ...
Higher level optimization bustage would be best caught when it occurs.  That
means figuring out this offending crash and then putting up a tinderbox to catch
future bustage.  Back to Roland.

Marking bug as WorksForMe, patched versions of Sun Workshop 6 Update 2 now work
properly with -xO4 ...
