Upstream commit 2017-08-09
|
|
|
53dace |
PR libstdc++/81751 don't call fflush(NULL)
|

|
|
|
53dace |
added these test cases as part of verifying the behavior of sys_open (that
|
|
|
53dace |
it resets errno and doesn't call fflush on NULL).
|
|
|
53dace |
|
|
|
53dace |
These symbols are in the system stdlib when run from DTS and thus aren't
|
|
|
53dace |
fixed by the above change:

1521: 000000000007c430 104 FUNC GLOBAL DEFAULT 12 std::__basic_file<char>::sys_open(int, std::_Ios_Openmode)@@GLIBCXX_3.4

2895: 000000000007c730 95 FUNC GLOBAL DEFAULT 12 std::__basic_file<char>::sys_open(_IO_FILE*, std::_Ios_Openmode)@@GLIBCXX_3.4
|
|
|
53dace |
|
|
|
53dace |
This patch disables the non-fixed assertions.
