* Fix some rather confusing indentation and control flow in the errnoChandler Carruth2013-09-02
| | | | | | | | | | | | | printing routine. This is made harder to see due to the surprising formatting, inconsistent brace usage, and repeated conditions that all test the same thing. The only "consequence" of this bug is re-assigning 'str' to an empty string when computing the error string for an error number of 0 in the event of a non-GNU strerror_r routine. So, nothing to see here other than cleanup. It did help me find PR17055 in clang-format though. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@189734 91177308-0d34-0410-b5e6-96231b3b80d8
* Remove dead or useless header checks from cmake and autoconfReid Kleckner2013-07-26
| | | | | | | | | | On Windows, this improves clean cmake configuration time on my workstation from 1m58s to 1m32s, which is pretty significant. There's probably more that can be done here, but this is the low hanging fruit. Eric volunteered to regenerate ./configure for me. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187209 91177308-0d34-0410-b5e6-96231b3b80d8

* llvm/lib/Support/Errno.cpp: [Win32] Fix usage of strerror_s().NAKAMURA Takumi2012-06-24
| | | | | | FYI, two arguments of strerror_s() is provided in C++ on msvc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159103 91177308-0d34-0410-b5e6-96231b3b80d8
* lib/Support/Errno.cpp: Check strerror_s() with HAVE_DECL_STRERROR_S in ↵NAKAMURA Takumi2011-02-09
| | | | | | | | | | | config.h.*. AC_CHECK_FUNCS seeks a symbol only in libs. We should check the declaration in string.h. FIXME: I have never seen mingw(s) have strerror_s() (not _strerror_s()). FIXME: Autoconf/CMake may seek strerror_s() with the definition MINGW_HAS_SECURE_API in future. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125172 91177308-0d34-0410-b5e6-96231b3b80d8
