This patch is a really simple one without any side-effects. The problem is, that gcc for x86-64 by default has -fomit-frame-pointer switched on when optimalization is requested. People don't know it and are complaining that (diplomaticaly said) "gdb doesn't work" (depending on their attitude :-). The only thing this patch does is, that it prints a note, when x86_64_skip_prologue doesn't see "push %rbp" as the very first instruction of a given function. The note is printed only once. That's all. I'd like to see it in 5.2 to teach people that they should explicitly use -fno-omit-frame-pointer when compiling a code for debugging. Can I commit? I'll remove this note as soon as I fix dwarf2 reader to handle even optimized code. 2002-04-26 Michal Ludvig * x86-64-tdep.c (x86_64_skip_prologue): Print note when debugging code without frame pointers.
