From cf48cf23de9207e4000df91aadc0beaa0989e33d Mon Sep 17 00:00:00 2001 From: Rafael Espindola Date: Mon, 29 Jul 2013 12:40:31 +0000 Subject: 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187353 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Object/Archive.cpp | 8 ++++++-- 1 file changed, 6 insertions(+), 2 deletions(-) (limited to 'lib/Object') diff --git a/lib/Object/Archive.cpp b/lib/Object/Archive.cpp index c6cf219..71efca2 100644 --- a/lib/Object/Archive.cpp +++ b/lib/Object/Archive.cpp @@ -385,7 +385,7 @@ Archive::Symbol Archive::Symbol::getNext() const { } Archive::symbol_iterator Archive::begin_symbols() const { - if (SymbolTable == end_children()) + if (!hasSymbolTable()) return symbol_iterator(Symbol(this, 0, 0)); const char *buf = SymbolTable->getBuffer().begin(); @@ -408,7 +408,7 @@ Archive::symbol_iterator Archive::begin_symbols() const { } Archive::symbol_iterator Archive::end_symbols() const { - if (SymbolTable == end_children()) + if (!hasSymbolTable()) return symbol_iterator(Symbol(this, 0, 0)); const char *buf = SymbolTable->getBuffer().begin(); @@ -444,3 +444,7 @@ Archive::child_iterator Archive::findSym(StringRef name) const { } return end_children(); } + +bool Archive::hasSymbolTable() const { + return SymbolTable != end_children(); +} -- cgit v1.1
