Hi Tom,
Hi Jonathan,
After the above GDB patch I see 2 new failures both for aarch64-linux-gnu and
arm-linux-gnueabihf in GCC's libstdc++ testsuite. The log [1] says:
===
$35 = warning: RTTI symbol not found for class 'main::custom_cat'
warning: RTTI symbol not found for class 'main::custom_cat'
got: $35 = warning: RTTI symbol not found for class 'main::custom_cat'
FAIL: libstdc++-prettyprinters/cxx11.cc print emiaow
skipping: warning: RTTI symbol not found for class 'main::custom_cat'
std::error_code = {std::_V2::error_category: 42}
skipping: std::error_code = {std::_V2::error_category: 42}
$36 = warning: RTTI symbol not found for class 'main::custom_cat'
warning: RTTI symbol not found for class 'main::custom_cat'
got: $36 = warning: RTTI symbol not found for class 'main::custom_cat'
FAIL: libstdc++-prettyprinters/cxx11.cc print ecmiaow
===
Which way should I dig -- GDB or libstdc++? Does this look like libstdc++
testcase needs an update?
