2012-11-28Add backreference matching capabilities to Support/Regex, withEli Bendersky
appropriate unit tests. This change in itself is not expected to affect any functionality at this point, but it will serve as a stepping stone to improve FileCheck's variable matching capabilities. Luckily, our regex implementation already supports backreferences, although a bit of hacking is required to enable it. It supports both Basic Regular Expressions (BREs) and Extended Regular Expressions (EREs), without supporting backrefs for EREs, following POSIX strictly in this respect. And EREs is what we actually use (rightly). This is contrary to many implementations (including the default on Linux) of POSIX regexes, that do allow backrefs in EREs. Adding backref support to our EREs is a very simple change in the regcomp parsing code. I fail to think of significant cases where it would clash with existing things, and can bring more versatility to the regexes we write. There's always the danger of a backref in a specially crafted regex causing exponential matching times, but since we mainly use them for testing purposes I don't think it's a big problem. [it can also be placed behind a flag specific to FileCheck, if needed].

2012-11-19Allow using MemoryBuffers with yaml::Stream directly.Sean Silva
The rationale is to get YAML filenames in diagnostics from yaml::Stream::printError -- currently the filename is hard-coded as "YAML" because there's no buffer information available.

2012-11-15PathV2: Fix a possible infinite loop.Daniel Dunbar
- The code could infinite loop trying to create unique files, if the directory containing the unique file exists, but open() calls on non-existent files in the path return ENOENT. This is true on the /dev/fd filesystem, for example. - Will add a clang side test case for this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168081 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-29Implement arithmetic on APFloat with PPCDoubleDouble semantics byUlrich Weigand
treating it as if it were an IEEE floating-point type with 106-bit mantissa.
