When we place a breakpoint on the line where 32 the function name is declared, we expect GDB to skip the function's 33 prologue, and insert the breakpoint on the first line of "user" code 34 for that function, which we have set up to be that single statement 35 break-include.inc provides. 36 37 The purpose of this testcase is to verify that, when we insert 38 that breakpoint, GDB reports the location as being in that include 39 file, but also using the correct line number inside that include 40 file -- NOT the line number we originally used to insert the 41 breakpoint, nor the location where the file is included from. 42 In order to verify that GDB shows the right line number, we must 43 be careful that this first statement located in break-include.inc 44 and our function are not on the same line number. Otherwise, 45 we could potentially have a false PASS. 46 47 This is why we implement the following function as far away 48 from the start of this file as possible, as we know that 49 break-include.inc is a fairly short file (copyright header 50 and single statement only). */ 51 52 int 53 next (int i) /* break here */ 54 { 55 #include "break-include.inc" 56 return i; 57 } 58
