Duncan Sands f9cf4ffcc7 Fix windows build, patch by Howard Su. 
llvm-svn: 74697
 2009-07-02 12:09:50 +00:00
Jeffrey Yasskin 1a93330ffa Add a portable strerror*() wrapper, llvm::sys::StrError(). This includes the 
Windows variant, strerror_s, but I couldn't test that.

I'll update configure and config.h.in in a subsequent patch.

Owen Anderson 021c3b0756 Guard dynamic library loading. 
I did my best at implementing this for Win32, but I don't have a way to test it.
Can someone with access to a Win32 machine test/fix this?

llvm-svn: 73710
 2009-06-18 18:26:15 +00:00
Owen Anderson 68f6598c69 Insert a SmartMutex templated class into the class hierarchy, which takes a template parameter specifying whether this mutex 
should become a no-op when not running in multithreaded mode.  Make sys::Mutex a typedef of SmartMutex<false>, to preserve source compatibility.

Owen Anderson 74af4ee79d Improve the Win32 reader-writer lock implementation by making it just a normal 
lock.  This is obviously bad, but at least it's threadsafe!  If you know how
to improve this in a pre-Vista friendly well, patches welcome!

Dan Gohman 970da81e8a glibc has two versions of strerror_r, a standards compliant one and a GNU 
specific one. The GNU one is chosen when _GNU_SOURCE is defined. g++ always
defines _GNU_SOURCE on linux platforms because glibc's headers won't compile
in C++ mode without it. The GNU strerror_r doesn't always modify the buffer
which causes empty error messages on linux.

This patch changes MakeErrMsg to use the return value of strerror_r to get
the string instead of assuming the buffer will be modified, on GLIBC.

Owen Anderson e5370f409b Move atomic operations' definitions out of line. While this seems kind of silly, 
all kinds of problems caused by including windows.h and/or config.h in an LLVM header.

Douglas Gregor b81294d989 termios.h contains the winsize structure we need to determine the 
width of a terminal. Don't try to get the width of a terminal if we
don't have this header.
