Rafael Espindola aca9739a1a Rules adjustments in order to build on DragonFly BSD. 
Patch by Robin Hahling.

llvm-svn: 193750
 2013-10-31 14:35:00 +00:00
Rafael Espindola 6ee163875c Check for $PWD in llvm::sys::current_path. 
Some users (clang, libTooling) require this. After this patch we can remove
the calls to getenv("PWD") from clang.

Rafael Espindola d123099abc Make file_status::getUniqueID const. 
llvm-svn: 187383
 2013-07-29 21:55:38 +00:00
Rafael Espindola 7f822a9306 Include st_dev to make the result of getUniqueID actually unique. 
This will let us use getUniqueID instead of st_dev directly on clang.

Reid Kleckner 37f69de11b Remove dead or useless header checks from cmake and autoconf 
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.

Rafael Espindola 67080cec25 Split openFileForWrite into windows and unix versions. 
It is similar to 186511, but for creating files for writing.

llvm-svn: 186679
 2013-07-19 15:02:03 +00:00
Rafael Espindola 213c4cb18c Remove dead code. 
llvm-svn: 186561
 2013-07-18 03:29:51 +00:00
Rafael Espindola a0d9b6b693 Split openFileForRead into Windows and Unix versions. 
This has some advantages:

* Lets us use native, utf16 windows functions.
* Easy to produce good errors on windows about trying to use a
directory when we want a file.
* Simplifies the unix version a bit.

Rafael Espindola b6fea4c618 Don't fallback to copy + delete in rename. 
Rename's documentation says "Files are renamed as if by POSIX rename()". and it
is used for atomically updating output files from a temporary. Having rename
fallback to a non atomic copy has the potential to hide bugs, like using
a temporary file in /tmp instead of a unique name next to the final destination.

llvm-svn: 186483
 2013-07-17 03:33:41 +00:00
Rafael Espindola 77021c9487 Add a version of sys::fs::status that uses fstat. 
llvm-svn: 186378
 2013-07-16 03:20:13 +00:00
Rafael Espindola 9da91a0e03 Instead friending status, provide windows and posix constructors to file_status. 
This opens the way of having static helpers in the .inc files that can
construct a file_status.

llvm-svn: 186376
 2013-07-16 02:55:33 +00:00
Rafael Espindola 4d08d8bada Use status to implement file_size. 
The status function is already using a syscall that returns the file size.
Remember it and implement file_size as a simple wrapper.

No functionally change, but clients that already use status now can avoid
calling file_size.

Rafael Espindola a8a9f1baf0 We now always create files with the correct permissions. Simplify the interface.

 2013-07-08 16:42:01 +00:00
Eric Christopher a24dc7fa8c Reapply r185601 with a fix for the cmake build. 
llvm-svn: 185605
 2013-07-04 01:10:38 +00:00
Eric Christopher 3eb07a0963 Temporarily revert 185601 as it caused cmake build regressions. 
llvm-svn: 185603
 2013-07-04 00:51:26 +00:00
Eric Christopher aaf58cc3c4 Add support for futimens for platforms that don't support futimes. 
Patch by pashev.igor.

llvm-svn: 185601
 2013-07-04 00:47:09 +00:00
Patrik Hagglund dcc336bf8e Suppress GCC "control reaches end of non-void function" warning. 
llvm-svn: 185136
 2013-06-28 06:54:05 +00:00
Rafael Espindola e79a87226a Improvements to unique_file and createUniqueDirectory. 
* Don't try to create parent directories in unique_file. It had two problem:
   * It violates the contract that it is atomic. If the directory creation
     success and the file creation fails, we would return an error but the
     file system was modified.
   * When creating a temporary file clang would have to first check if the
     parent directory existed or not to avoid creating one when it was not
     supposed to.

* More efficient implementations of createUniqueDirectory and the unique_file
  that produces only the file name. Now all 3 just call into a static
  function passing what they want (name, file or directory).

Clang also has to be updated, so tests might fail if a bot picks up this commit
and not the corresponding clang one.

llvm-svn: 184219
 2013-06-18 19:46:19 +00:00
Rafael Espindola 158d537c5a Add GetCurrentDirectory back. 
It looks like clang-tools-extra/unittests/cpp11-migrate/TransformTest.cpp
depends on the behaviour of the old one on Windows. Maybe a difference
between GetCurrentDirectoryA and GetCurrentDirectoryW?

llvm-svn: 184009
 2013-06-14 21:41:33 +00:00
Rafael Espindola ef03b9fc52 Replace use of PathV1.h in MCContext.cpp.

Sylvestre Ledru 12c44e57f5 The assumption that /proc/self/exe always exists is incorrect. 
For example, under a Linux chroot, /proc/ might not be mounted.
Therefor, we test if this file exist. If it is the case, use it (the current
behavior). Otherwise, we fall back to the detection used by *BSD.

The issue has been reported initially on the Debian bug tracker:
http://bugs.debian.org/674588
