However, GDB expression semantics are not -exactly C semantics. This is a bug, strictly speaking, but it's not one I -know how to fix. If @samp{x} is a program variable of type int, then it -is also type int to GDB, but @samp{x + 1} is long long, as is @samp{x + y} -or any other expression requiring computation. So is the expression -@samp{1}, or any other constant. You only really have to watch out for -calls. The innocuous expression @samp{list_node (0x80001234)} has an -argument of type long long. You must explicitly cast it to int. - -It is not possible to continue after an uncaught fatal signal by using -@samp{signal 0}, @samp{return}, @samp{jump}, or anything else. The difficulty is with -Unix, not GDB. - -I have made no big effort to make such things as single-stepping a -@kbd{join} instruction do something reasonable. If the program seems to -hang when doing this, type @kbd{ctrl-c} and @samp{cont}, or use -@samp{thread} to shift to a live thread. Single-stepping a @kbd{spawn} -instruction apparently causes new threads to be born with their T bit set; -this is not handled gracefully. When a thread has hit a breakpoint, other -threads may have invisibly hit the breakpoint in the background; if you -clear the breakpoint gdb will be surprised when threads seem to continue -to stop at it. All of these situations produce spurious signal 5 traps; -if this happens, just type @samp{cont}. If it becomes a nuisance, use -@samp{handle 5 nostop}. (It will ask if you are sure. You are.) - -There is no way in GDB to store a float in a register, as with -@kbd{set $s0 = 3.1416}. The identifier @kbd{$s0} denotes an integer, -and like any C expression which assigns to an integer variable, the -right-hand side is casted to type int. If you should need to do -something like this, you can assign the value to @kbd{@{float@} ($sp-4)} -and then do @kbd{set $s0 = $sp[-4]}.
