718 | 4.0-4.11 used the LOC_REGISTER. | |
8d3b0994 AC |
719 | |
720 | Reasons for using the LOC_ARG: | |
033a42c2 MK |
721 | |
722 | (1) Because find_saved_registers may be slow for | |
723 | remote debugging. | |
724 | ||
725 | (2) Because registers are often re-used and stack | |
726 | slots rarely (never?) are. Therefore using | |
727 | the stack slot is much less likely to print | |
728 | garbage. | |
8d3b0994 AC |
729 | |
730 | Reasons why we might want to use the LOC_REGISTER: | |
033a42c2 MK |
731 | |
732 | (1) So that the backtrace prints the same value | |
733 | as "print foo". I see no compelling reason | |
734 | why this needs to be the case; having the | |
735 | backtrace print the value which was passed | |
736 | in, and "print foo" print the value as | |
737 | modified within the called function, makes | |
738 | perfect sense to me. | |
739 | ||
740 | Additional note: It might be nice if "info args" | |
741 | displayed both values. | |
742 | ||
743 | One more note: There is a case with SPARC | |
744 | structure passing where we need to use the | |
745 | LOC_REGISTER, but this is dealt with by creating | |
746 | a single LOC_REGPARM in symbol reading. */ | |
