all of the features in the current working draft of the upcoming C++ standard, provisionally named C++1y. The code generator's performance is greatly increased, and the loop auto-vectorizer is now enabled at -Os and -O2 in addition to -O3. The PowerPC backend has made several major improvements to code generation quality and compile time, and the X86, SPARC, ARM32, Aarch64 and SystemZ backends have all seen major feature work. Release notes for llvm and clang can be found here: <http://llvm.org/releases/3.4/docs/ReleaseNotes.html> <http://llvm.org/releases/3.4/tools/clang/docs/ReleaseNotes.html> MFC after: 1 month

.SH SYNOPSIS
|
|
.sp
|
|
\fBtblgen\fP [\fIoptions\fP] [\fIfilename\fP]
|
|
.SH DESCRIPTION
|
|
.sp
|
|
\fBtblgen\fP translates from target description (\fB\&.td\fP) files into C++
|
|
code that can be included in the definition of an LLVM target library. Most
|
|
users of LLVM will not need to use this program. It is only for assisting with
|
|
writing an LLVM target backend.
|
|
.sp
|
|
The input and output of \fBtblgen\fP is beyond the scope of this short
|
|
introduction. Please see \fB\&../TableGenFundamentals\fP\&.
|
|
.sp
|
|
The \fIfilename\fP argument specifies the name of a Target Description (\fB\&.td\fP)
|
|
file to read as input.
