They were usually revealed by the MCU halting or repeatedly rebooting. Fortunately, since the EXP430F5438 demo prints to the LCD, and the problems weren't obvious until task switches started, "printf" mostly worked to locate the trouble areas. For the rest, I just used mspdebug directly, with its breakpoints and disassembly support, to reach the "that can't possibly be right" epiphanies that revealed what was going on. Many thanks to Daniel Beer for mspdebug. If you go that route, I suggest pulling the latest git reversion: there were a few disassembly issues related to 20-bit code that have been fixed now. There are some complaints about invalid integer/pointer casts you might see, but for the most part those are benign. > I'm asking because debugging compiler issues on the target system can be > a pain, but if you learn of the problems before hand, then it's way > easier to know. Yes. Personally, I'm shocked that there were so few issues, and they were so easy to figure out. I'm really dreading the need to fix large memory support, as that's going to be forcing gcc to do something it considers unnatural. I should point out that gdb may or may not work now. My bet is "not", at least for anything involving 20-bit code, and I hold that belief firmly enough that I haven't even tried. Anybody adventurous is welcome to give it a go, but I have no funding to support porting all the binutils/BFD changes into gdb at this time.
