This patch fixes two fails in dw2-compdir-oldgcc.exp I've seen on arm target thumb mode. FAIL: gdb.dwarf2/dw2-compdir-oldgcc.exp: info source gcc42 FAIL: gdb.dwarf2/dw2-compdir-oldgcc.exp: info source gcc43 When fill in DW_AT_low_pc, the label should be used rather than the function, otherwise, the LSB bit of the address in DW_AT_low_pc is set and the debug info is wrong. This patch is to add two labels for functions gcc42 and gcc43 respectively, and use them. These two fails are fixed. gdb/testsuite: 2014-11-22 Yao Qi <yao@codesourcery.com> * gdb.dwarf2/dw2-compdir-oldgcc.S: Define label .Lgcc42_procstart and .Lgcc43_procstart. Use .Lgcc42_procstart instead of gcc42. Use .Lgcc43_procstart instead of gcc43.
