OK, I can do that. ------------------------------------------------------------------------------ src/hotspot/share/utilities/macros.hpp 645 #if FILE_MACRO_OFFSET 646 #define THIS_FILE (__FILE__ + FILE_MACRO_OFFSET) 647 #else 648 #define THIS_FILE __FILE__ 649 #endif Is the "#if FILE_MACRO_OFFSET" an intentional test for 0, or is this an implicit test for "defined"? If the former, e.g. we're assuming it will always be defined but might have a 0 value, then I'd skip it and just unconditionally define THIS_FILE as (__FILE__ + FILE_MACRO_OFFSET).
Right, that makes sense. I was sort of hedging for all possibilities here, but as the build logic is currently structured, it will always be defined, just sometimes 0.

If the latter, some compilers will (with some warning levels or options, such as gcc -Wundef) complain about the (specified by the standard) implicit conversion to 0 for an unrecognized identifier in an #if expression, and an #ifdef should be used to protect against that. ------------------------------------------------------------------------------
