llvm/lib/Support, branch release_28

Use the FindProgramByName fallback only with known absolute paths.

2010-09-02T22:32:38Z

I wasn't able to convince myself that all GetMainExecutable implementations always return absolute paths; this prevents unexpected behavior in case they ever don't. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112888 91177308-0d34-0410-b5e6-96231b3b80d8

After some discussion with djg, teach SmallVector to grow from a zero

capacity and remove the workaround in SmallVector. There are some theoretical benefits to a N->2N+1 growth policy anyway. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112870 91177308-0d34-0410-b5e6-96231b3b80d8

llvm::FindExecutable(): Retrieve the name with suffix.exe, if available.

Make tool_output_file's raw_ostream instance a member variable instead

2010-09-01T14:20:41Z

of a base class. This makes it possible to unregister the file from FilesToRemove when the file is done. Also, this eliminates the need for formatted_tool_output_file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112706 91177308-0d34-0410-b5e6-96231b3b80d8

Remove a hack that tries to understand incorrect triples from the

2010-08-30T10:57:54Z

Triple class constructor. Only valid triples should now be used inside LLVM - front-ends are now responsable for rejecting or correcting invalid target triples. The Triple::normalize method can be used to straighten out funky triples provided by users. Give this a whirl through the buildbots to see if I caught all places where triples enter LLVM. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112470 91177308-0d34-0410-b5e6-96231b3b80d8

StringRef::compare_numeric also differed from StringRef::compare for characters > 127.

Do unsigned char comparisons in StringRef::compare_lower to be more consistent with compare in corner cases.

Use Bits.data() instead of &Bits[0].

Avoid O(n*m) complexity in StringRef::find_first(_not)_of(StringRef).

- Cache used characters in a bitset to reduce memory overhead to just 32 bytes. - On my core2 this code is faster except when the checked string was very short (smaller than the list of delimiters). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111817 91177308-0d34-0410-b5e6-96231b3b80d8
