Using gcc version 4.0.1 20050727 (current Fedora Core 4 compiler) on i386, and compiling tuplesort.c as you did, I find: -O2: warning goes away between 800 and 900 -O3: warning is always there (tried values up to 10000000) (the latter behavior may indicate a bug, not sure). What's even more interesting is that the warning does not appear in either case if I omit -finline-limit --- so the default value is plenty. At least on this particular compiler, the proposed switch would be counterproductive. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 2: Don't 'kill -9' the postmaster
