When running test-case gdb.base/consecutive.exp with gcc-8 instead of gcc-7, we get: ... (gdb) step^M ^M -Breakpoint 3, 0x00000000004004b1 in foo () at consecutive.c:10^M +Breakpoint 3, foo () at consecutive.c:10^M 10 return a[0] + a[1] + a[2] + a[3] + a[4] + a[5] + a[6];^M -(gdb) PASS: gdb.base/consecutive.exp: stopped at bp, 2nd instr +(gdb) FAIL: gdb.base/consecutive.exp: stopped at bp, 2nd instr ... This is due to the fact that gcc-8 generates more precise line info, making the breakpoint address a "recommended breakpoint location", and consequently gdb doesn't print the address prefix anymore. Fix the FAIL by checking in the test-case whether the breakpoint address is at "recommended breakpoint location" or not. gdb/testsuite/ChangeLog: 2020-05-06 Tom de Vries <tdevries@suse.de> * lib/gdb.exp (is_stmt_addresses, hex_in_list): New proc, factored out of ... * gdb.base/async.exp: ... here. * gdb.base/consecutive.exp: Handle if 2nd breakpoint is at a "recommended breakpoint location".
