Yes that’s what I want.

Yesterday I was using gdb to step into the interpreter generation code to see what’s generated for a particular routine for MethodHandles. The debug build contains a LOT of runtime verification code in the generated code and I couldn’t figure out what’s happening. The product build just generates 10 instructions. So you want to have a way to force -O0 for all compiled files? Something like "bash configure --with-debug-level=release --with-optimization=none", or possibly "make OPTIMIZATION=NONE"?

Or are you happy with the optimization level of a slowdebug build, and only want to adjust the value of PRODUCT and ASSERT for hotspot to match what's done for a release build? Something like "bash configure --enable-hotspot-product-build"?

If I understand Ioi correctly, he wants a build with PRODUCT and !ASSERT but with debug symbols and no optimizations? So, no assertions and all switches with product defaults?

I can see that this could make sense in certain scenarios. ..Thomas On Tue, Apr 10, 2018 at 10:27 PM, Magnus Ihse Bursie <magnus.ihse.bursie at oracle.com_ _<mailto:magnus.ihse.bursie at oracle.com>> wrote: On 2018-04-10 02:00, Ioi Lam wrote: Sometimes I want to debug the product build (I can't bother with turning off all the trueInDebug options in the hotspot globals.hpp). The only way that I have found to do this is: configure --with-native-debug-symbols=internal mv spec.gmk spec.gmk.old cat spec.gmk | sed -e 's/[-]O[0-9s]/-O0/g' > spec.gmk Is there (or should there be) a more elegant way to do it, like "configure --with-debug-level=slowproduct" :-) I'm not entirely sure of what you want to achieve. As I interepret your snippet above, you want no optimization and internal debug symbols..? How is that debugging a "product" build? /Magnus

Thanks - Ioi
