When running test-cases gdb.cp/*.exp with gcc 4.8.4, I run into compilation failures due to the test-cases requiring c++11 and the compiler defaulting to less than that. Fix this by compiling with -std=c++11. This exposes two FAILs in gdb/testsuite/gdb.cp/empty-enum.exp due to gcc PR debug/16063, so xfail those. Also require have_compile_flag -std=c++17 in gdb.cp/constexpr-field.exp to prevent compilation failure. Tested on x86_64-linux.

# Test how GDB displays empty enums. At one point an enum with no
|
|
# enumeration values would be considered a flag enum, and, as a
|
|
# consequence any value with that type would display like:
|
|
#
|
|
# (gdb) print enum_var
|
|
# $1 = (unknown: 0x8)
|
|
#
|
|
# Which resulted in a lot of noise. Now GDB treats empty enums as a
|
|
# non-flag enum, and should print them like this:
|
|
#
|
|
# (gdb) print enum_var
|
|
# $1 = 8
|
|
#
|
|
# This test checks this behaviour.
