Craig Topper	c34a25d59d	[C++] Use 'nullptr'. ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@207394 91177308-0d34-0410-b5e6-96231b3b80d8	2014-04-28 04:05:08 +00:00
Chandler Carruth	7f1946408d	Teach the pass manager's execution dump to print the current time before ... each line. This is particularly nice for tracking which run of a particular pass over a particular function was slow. This also required making the TimeValue string much more useful. First, there is a standard format for writing out a date and time. Let's use that rather than strings that would have to be parsed. Second, actually output the nanosecond resolution that timevalue claims to have. This is proving useful working on PR19499, so I figured it would be generally useful to commit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@207385 91177308-0d34-0410-b5e6-96231b3b80d8	2014-04-27 23:59:25 +00:00
Rafael Espindola	71857ccdb8	Fix a FIXME about the format and add a test. ... While at it, use strftime on Unix too and use the thread safe versions of localtime. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186090 91177308-0d34-0410-b5e6-96231b3b80d8	2013-07-11 15:35:23 +00:00
Alexey Samsonov	9f306bdc70	Fix initialization-order bug in llvm::Support::TimeValue. TimeValue::now() is explicitly called during module initialization of lib/Support/Process.cpp. It reads the field of global object PosixZeroTime, which is not guaranteed to be initialized at this point. Found by AddressSanitizer with -fsanitize=init-order option. ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175509 91177308-0d34-0410-b5e6-96231b3b80d8	2013-02-19 11:35:39 +00:00
