* Fix Doxygen issues:Dmitri Gribenko2012-09-141-1/+1
| | | | | | | | | | | * wrap code blocks in \code ... \endcode; * refer to parameter names in paragraphs correctly (\arg is not what most people want -- it starts a new paragraph); * use \param instead of \arg to document parameters in order to be consistent with the rest of the codebase. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163902 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | variable if recursing fails to simplify it. Factor AliasedSymbol to be a method of MCSymbol. Update MCAssembler::EvaluateFixup to match the change in EvaluateAsRelocatableImpl. Remove the WeakRefExpr hack, as the object writer now sees the weakref with no extra effort needed. Nothing else is using MCTargetExpr, but keep it for now. Now that the ELF writer sees relocations with aliases, handle .weak foo2 foo2: .weak bar2 .set bar2,foo2 .quad bar2 the same way gas does and produce a relocation with bar2. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119152 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix PR8565.Rafael Espindola2010-11-151-0/+1
| | | | | | | | | | | This moves most of the isUsed logic to the MCSymbol itself. With this we get a bit more relaxed about allowing definitions after uses: uses that don't evaluate their argument immediately (jmp foo) are accepted. ddunbar, this was the smallest compromise I could think of that lets us accept gcc (and clang!) assembly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119144 91177308-0d34-0410-b5e6-96231b3b80d8

* Get MCSymbol out of the mangling business, and move all the logicChris Lattner2010-01-171-57/+4
| | | | | | | | | | | | to Mangler. Now MCSymbol just decides whether to slap quotes around a symbol when printing it. This also fixes some weirdness where two MCSymbols could be created for the same symbol, if one needed to be mangled and got mangled to the other one. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93690 91177308-0d34-0410-b5e6-96231b3b80d8
