2003-07-25Include vector into these two files to ensure that specializations likeVikram S. Adve
stl_bvector.h are correctly included into *anything* that includes hash_map or hash_set. ext/hash_map includes stl_vector.h directly and leaves out the specializations, causing truly nasty bugs due to inconsistent versions of vector<> being used for vector<bool> in different files. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7303 91177308-0d34-0410-b5e6-96231b3b80d8
2003-07-24Made a bunch of cleanups, as per Chris' recommendations:Misha Brukman
* Removed unused global and member variables * Fixed comments (CodeGeneratorBug.cpp) * Check for possibly failing GCC::create() and CBE::create() * Remove generated files after diffing the output (e.g., shared object) * Instead of using std::for_each, use explicit loops as std::for_each may duplicate the functor, and ours carries state * Changed member var from cl::opt<std::string> to just std::string * Fixed doxygen comments * Fixed string comparisons to use [ str.empty() ] instead of [ str == "" ] * Cache instances of CBE and GCC in BugDriver across compilations and executions while testing tools. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7302 91177308-0d34-0410-b5e6-96231b3b80d8
2003-07-24Cleanups:Brian Gaeke
Mangler.cpp: Constify parameter to makeNameProper, and use const_iterator. Make Count an unsigned int, and use utostr(). Don't name parameters things that start with underscore. Mangler.h: All of the above, and also: Add Emacs mode-line. Include <set>. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7301 91177308-0d34-0410-b5e6-96231b3b80d8

into this new support class. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7300 91177308-0d34-0410-b5e6-96231b3b80d8
2003-07-24Use unified CWriter-X86/Printer name mangler. Do not bother usingBrian Gaeke
SlotCalculator in CWriter. (Unfortunately, all this means a lot of X86/Printer's methods have to be de-constified again. Oh well.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7299 91177308-0d34-0410-b5e6-96231b3b80d8

2003-07-24Major addition to bugpoint: ability to debug code generators (LLC and LLI).Misha Brukman
The C backend is assumed correct and is used to generate shared objects to be loaded by the other two code generators. LLC debugging should be functional now, LLI needs a few more additions to work, the major one is renaming of external functions to call the JIT lazy function resolver. Bugpoint now has a command-line switch -mode with options 'compile' and 'codegen' to debug appropriate portions of tools. ExecutionDriver.cpp: Added implementations of AbstractInterpreter for LLC and GCC, broke out common code within other tools, and added ability to generate C code with CBE individually, without executing the program, and the GCC tool can generate executables shared objects or executables. If no reference output is specified to Bugpoint, it will be generated with CBE, because it is already assumed to be correct for the purposes of debugging using this method. As a result, many functions now accept as an optional parameter a shared object to be loaded in, if specified. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7293 91177308-0d34-0410-b5e6-96231b3b80d8

2003-07-24It doesn't appear that we need to #include these.Brian Gaeke
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7291 91177308-0d34-0410-b5e6-96231b3b80d8
2003-07-24Allow folding several instructions into casts, which can simplify a lotChris Lattner
of codes. For example, short kernel (short t1) { t1 >>= 8; t1 <<= 8; return t1; } became: short %kernel(short %t1.1) { %tmp.3 = shr short %t1.1, ubyte 8 ; <short> [#uses=1] %tmp.5 = cast short %tmp.3 to int ; <int> [#uses=1] %tmp.7 = shl int %tmp.5, ubyte 8 ; <int> [#uses=1] %tmp.8 = cast int %tmp.7 to short ; <short> [#uses=1] ret short %tmp.8 } before, now it becomes: short %kernel(short %t1.1) { %tmp.3 = shr short %t1.1, ubyte 8 ; <short> [#uses=1] %tmp.8 = shl short %tmp.3, ubyte 8 ; <short> [#uses=1] ret short %tmp.8 } which will become: short %kernel(short %t1.1) { %tmp.3 = and short %t1.1, 0xFF00 ret short %tmp.3 } This implements cast-set.ll:test4 and test5 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7290 91177308-0d34-0410-b5e6-96231b3b80d8

2003-07-24Constify most methods. We could have constified doInitialization andBrian Gaeke
doFinalization too except that would have made them shadow, not override, the parent class :-P. Allow *any* constant cast expression between pointers and longs, or vice-versa, or any widening (not just same-size) conversion that isLosslesslyConvertibleTo approves. This fixes oopack. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7288 91177308-0d34-0410-b5e6-96231b3b80d8
