New Revision: 184019
URL: http://llvm.org/viewvc/llvm-project?rev=184019&view=rev
Log:
Remove the LLVM specific archive index.
Archive files (.a) can have a symbol table indicating which object
files in them define which symbols. The purpose of this symbol table
is to speed up linking by allowing the linker the read only the .o
files it is actually going to use instead of having to parse every
object's symbol table.
LLVM's archive library currently supports a LLVM specific format for
such table. It is hard to see any value in that now that llvm-ld is
gone:
* System linkers don't use it: GNU ar uses the same plugin as the
linker to create archive files with a regular index. The OS X ar
creates no symbol table for IL files, I assume the linker just parses
all IL files.
* It doesn't interact well with archives having both IL and native objects.
* We probably don't want to be responsible for yet another archive
format variant.
This patch then:
* Removes support for creating and reading such index from lib/Archive.
* Remove llvm-ranlib, since there is nothing left for it to do.
We should in the future add support for regular indexes to llvm-ar for
both native and IL objects. When we do that, llvm-ranlib should be
reimplemented as a symlink to llvm-ar, as it is equivalent to "ar s".

-llvm-ranlib - Generate index for LLVM archive
-=============================================
-
-
-SYNOPSIS
---------
-
-
-**llvm-ranlib** [--version] [-help] <archive-file>
-
-
-DESCRIPTION
------------
-
-
-The **llvm-ranlib** command is similar to the common Unix utility, ``ranlib``. It
-adds or updates the symbol table in an LLVM archive file. Note that using the
-**llvm-ar** modifier *s* is usually more efficient than running **llvm-ranlib**
-which is only provided only for completness and compatibility. Unlike other
-implementations of ``ranlib``, **llvm-ranlib** indexes LLVM bitcode files, not
-native object modules. You can list the contents of the symbol table with the
-``llvm-nm -s`` command.
-
-
-OPTIONS
--------
-
-
-
-*archive-file*
-
- Specifies the archive-file to which the symbol table is added or updated.
-
-
-
-*--version*
-
- Print the version of **llvm-ranlib** and exit without building a symbol table.
-
-
-
-*-help*
-
- Print usage help for **llvm-ranlib** and exit without building a symbol table.
-
-
-
-
-EXIT STATUS
------------
-
-
-If **llvm-ranlib** succeeds, it will exit with 0. If an error occurs, a non-zero
-exit code will be returned.
