* Use status to implement file_size.Rafael Espindola2013-07-102-35/+1
| | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186016 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove unique_file now that it is unused.Rafael Espindola2013-07-051-17/+0
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185728 91177308-0d34-0410-b5e6-96231b3b80d8
* Add a createUniqueFile function and switch llvm's users of unique_file.Rafael Espindola2013-07-053-6/+16
| | | | | | | | | | | | | | This function is complementary to createTemporaryFile. It handles the case were the unique file is *not* temporary: we will rename it in the end. Since we will rename it, the file has to be in the same filesystem as the final destination and we don't prepend the system temporary directory. This has a small semantic difference from unique_file: the default mode is 0666. This matches the behavior of most unix tools. For example, with this change lld now produces files with the same permissions as ld. I will add a test of this change when I port clang over to createUniqueFile (next commit). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185726 91177308-0d34-0410-b5e6-96231b3b80d8

* Add a higher level createTemporaryFile function.Rafael Espindola2013-07-051-0/+34
| | | | | | | | This function is inspired by clang's Driver::GetTemporaryPath. It hides the pattern used for uniquing and requires simple file names that are always placed in the system temporary directory. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185716 91177308-0d34-0410-b5e6-96231b3b80d8

* Add a division operator to BlockFrequency.Jakob Stoklund Olesen2013-06-281-23/+35
| | | | | | | | | | | Allow a BlockFrequency to be divided by a non-zero BranchProbability with saturating arithmetic. This will be used to compute the frequency of a loop header given the probability of leaving the loop. Our long division algorithm already saturates on overflow, so that was a freebie. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185184 91177308-0d34-0410-b5e6-96231b3b80d8

* Improvements to unique_file and createUniqueDirectory.Rafael Espindola2013-06-283-241/+235
| | | | | | | | | | | | | | | | | | | * 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185126 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | either zero/NaN but allowed you to arbitrarily set the category of the float."" This reverts commit r185099. Looks like both the ppc-64 and mips bots are still failing after I reverted this change. Since: 1. The mips bot always performs a clean build, 2. The ppc64-bot failed again after a clean build (I asked the ppc-64 maintainers to clean the bot which they did... Thanks Will!), I think it is safe to assume that this change was not the cause of the failures that said builders were seeing. Thus I am recomitting. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185111 91177308-0d34-0410-b5e6-96231b3b80d8

This is causing a FileCheck failure on the 3dnow intrinsics on at least the mips/ppc bots but not on the x86 bots. Reverting while I figure out what is going on. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185099 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | but allowed you to arbitrarily set the category of the float. The category which an APFloat belongs to should be dependent on the actual value that the APFloat has, not be arbitrarily passed in by the user. This will prevent inconsistency bugs where the category and the actual value in APFloat differ. I also fixed up all of the references to this constructor (which were only in LLVM). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185095 91177308-0d34-0410-b5e6-96231b3b80d8
* Add a convenience createUniqueDirectory function.Rafael Espindola2013-06-271-0/+11
| | | | | | | | | | | There are a few valid situation where we care about the structure inside a directory, but not about the directory itself. A simple example is for unit testing directory traversal. PathV1 had a function like this, add one to V2 and port existing users of the created temp file and delete it hack to using it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185059 91177308-0d34-0410-b5e6-96231b3b80d8
* [APFloat] Convert all references to fcNormal to references to isFiniteNonZero().Michael Gottesman2013-06-261-30/+30
| | | | | | | | | | | | Currently inside APFloat fcNormal still implies the old definition of Normal (i.e. isFiniteNonZero) instead of the proper IEEE-754R definition that the external method isNormal() uses. This patch prepares for the internal switch inside APFloat by converting all references that check if a category is fcNormal directly with an indirect call via isFiniteNonZero(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185036 91177308-0d34-0410-b5e6-96231b3b80d8
