I have this cross-compiler at hand that cannot compile some of my
big files (a Bison parser) with -O2. Stacking -O0 on top of -O2
does the trick. But I don't know the recommended way to do that.
Since I'd like to the keep the good old -g -O2 for the rest of
the compilation, since I don't want to forbid the user from
passing -O2 in her flags, I'd really like to override this just
for this file. Compiling it as a library with specific CXXFLAGS
won't do the trick, since CXXFLAGS, of course, appear after
$(libparser_la_CXXFLAGS):
libparser_la-ugrammar.lo: ugrammar.cc
if $(LIBTOOL) --tag=CXX --mode=compile $(CXX) $(DEFS) $
(DEFAULT_INCLUDES) $(INCLUDES) $(AM_CPPFLAGS) $(CPPFLAGS) $
(libparser_la_CXXFLAGS) $(CXXFLAGS) -MT libparser_la-ugrammar.lo -MD -
MP -MF "$(DEPDIR)/libparser_la-ugrammar.Tpo" -c -o libparser_la-
ugrammar.lo `test -f 'ugrammar.cc' || echo '$(srcdir)/'`ugrammar.cc; \
then mv -f "$(DEPDIR)/libparser_la-ugrammar.Tpo" "$(DEPDIR)/
libparser_la-ugrammar.Plo"; else rm -f "$(DEPDIR)/libparser_la-
ugrammar.Tpo"; exit 1; fi
What would be the cleanest means to handle this exception?
Thanks!
