307 | Reasons for using the LOC_ARG: | |
308 | (1) because find_saved_registers may be slow for remote | |
309 | debugging, | |
310 | (2) because registers are often re-used and stack slots | |
311 | rarely (never?) are. Therefore using the stack slot is | |
312 | much less likely to print garbage. | |
313 | ||
314 | Reasons why we might want to use the LOC_REGISTER: | |
315 | (1) So that the backtrace prints the same value as | |
316 | "print foo". I see no compelling reason why this needs | |
317 | to be the case; having the backtrace print the value which | |
318 | was passed in, and "print foo" print the value as modified | |
319 | within the called function, makes perfect sense to me. | |
320 | ||
321 | Additional note: It might be nice if "info args" displayed | |
322 | both values. | |
323 | One more note: There is a case with sparc structure passing | |
324 | where we need to use the LOC_REGISTER, but this is dealt with | |
325 | by creating a single LOC_REGPARM in symbol reading. */ | |
