Add an initial implementation of archive symbol table generation. The symbol table has forward references in the file. Instead of allocating a temporary buffer or counting the size and then writing, this implementation writes a dummy value first and patches it once the final value is known. There is room for performance improvement. I will implement them as soon as I get some other features (like a ranlib mode) in. llvm-svn: 186934

Add support for the 's' operation to llvm-ar. If no other operation is specified, 's' becomes an operation instead of an modifier. The s operation just creates a symbol table. It is the same as running ranlib. We assume the archive was created by a sane ar (like llvm-ar or gnu ar) and if the symbol table is present, then it is current. We use that to optimize the most common case: a broken build system that thinks it has to run ranlib. llvm-svn: 187353

Add support for Darwin’s static library table of contents with 64-bit offsets to the archive members. Darwin added support in its Xcode 8.0 tools (released in the beta) for static library table of contents with 64-bit offsets to the archive members. The change is very straight forward. The table of contents member is named ___.SYMDEF_64 or "___.SYMDEF_64 SORTED" and same layout is used but with fields using 64 bit values instead of 32 bit values. rdar://26869808 llvm-svn: 273058

llvm-ar: align the first archive member consistently. Before we were aligning the member after the symbol table to 4 but other members to 8. llvm-svn: 314010
2017-09-23 02:36:00 +08:00
Test that we pad the symbol table so that it ends in a multiple of 8 bytes:
8 + 60 + 52 == 120

llvm-ar: Darwin archive format fixes. * Support writing the DARWIN64 symbol table format. * In darwin archives, emit a symbol table whenever requested, even when there are no members, as the apple linker will abort if given an archive without a symbol table. Added tests for same, and also simplified and moved the GNU 64-bit symbol table test into archive-symtab.test. llvm-svn: 344183

** Test the behavior of an empty archive:
No symbol table emitted for GNU archives
RUN: rm -f %t.a
RUN: llvm-ar rcs --format=gnu %t.a
RUN: not grep -q '/ ' %t.a
No symbol table for BSD archives
RUN: rm -f %t.a
RUN: llvm-ar rcs --format=bsd %t.a
RUN: not grep -q '__\.SYMDEF' %t.a
And we do emit a symbol table for DARWIN archives
RUN: rm -f %t.a
RUN: llvm-ar rcs --format=darwin %t.a
RUN: grep -q '__\.SYMDEF' %t.a
