* Second installment of "BasicBlock operands to the back"Gabor Greif2009-03-132-2/+2
| | | | | | | | | | | | | | | | | | changes. For InvokeInst now all arguments begin at op_begin(). The Callee, Cont and Fail are now faster to get by access relative to op_end(). This patch introduces some temporary uglyness in CallSite. Next I'll bring CallInst up to a similar scheme and then the uglyness will magically vanish. This patch also exposes all the reliance of the libraries on InvokeInst's operand ordering. I am thinking of taking care of that too. llvm-svn: 66920

* Introduce new linkage types linkonce_odr, weak_odr, common_odrDuncan Sands2009-03-071-1/+1
| | | | | | | | | | | | | | | | | | | | | and extern_weak_odr. These are the same as the non-odr versions, except that they indicate that the global will only be overridden by an *equivalent* global. In C, a function with weak linkage can be overridden by a function which behaves completely differently. This means that IP passes have to skip weak functions, since any deductions made from the function definition might be wrong, since the definition could be replaced by something completely different at link time. This is not allowed in C++, thanks to the ODR (One-Definition-Rule): if a function is replaced by another at link-time, then the new function must be the same as the original function. If a language knows that a function or other global can only be overridden by an equivalent global, it can give it the weak_odr linkage type, and the optimizers will understand that it is alright to make deductions based on the function body. The code generators on the other hand map weak and weak_odr linkage to the same thing. llvm-svn: 66339

* Teach IndVarSimplify to optimize code using the C "int" type forDan Gohman2009-02-121-27/+73
| | | | | | | | | | | | | | | | | | | | | | | | | | | | loop induction on LP64 targets. When the induction variable is used in addressing, IndVars now is usually able to inserst a 64-bit induction variable and eliminates the sign-extending cast. This is also useful for code using C "short" types for induction variables on targets with 32-bit addressing. Inserting a wider induction variable is easy; the tricky part is determining when trunc(sext(i)) expressions are no-ops. This requires range analysis of the loop trip count. A common case is when the original loop iteration starts at 0 and exits when the induction variable is signed-less-than a fixed value; this case is now handled. This replaces IndVarSimplify's OptimizeCanonicalIVType. It was doing the same optimization, but it was limited to loops with constant trip counts, because it was running after the loop rewrite, and the information about the original induction variable is lost by that point. Rename ScalarEvolution's executesAtLeastOnce to isLoopGuardedByCond, generalize it to be able to test for ICMP_NE conditions, and move it to be a public function so that IndVars can use it. llvm-svn: 64407

| | | | | | | | | | | | | | | | | | | | | | | | | | | | information output. However, many target specific tool chains prefer to encode only one compile unit in an object file. In this situation, the LLVM code generator will include debugging information entities in the compile unit that is marked as main compile unit. The code generator accepts maximum one main compile unit per module. If a module does not contain any main compile unit then the code generator will emit multiple compile units in the output object file. [Part 1] Update DebugInfo APIs to accept optional boolean value while creating DICompileUnit to mark the unit as "main" unit. By defaults all units are considered non-main. Update SourceLevelDebugging.html to document "main" compile unit. Update DebugInfo APIs to not accept and encode separate source file/directory entries while creating various llvm.dbg.* entities. There was a recent, yet to be documented, change to include this additional information so no documentation changes are required here. Update DwarfDebug to handle "main" compile unit. If "main" compile unit is seen then all DIEs are inserted into "main" compile unit. All other compile units are used to find source location for llvm.dbg.* values. If there is not any "main" compile unit then create unique compile unit DIEs for each llvm.dbg.compile_unit. [Part 2] Create separate llvm.dbg.compile_unit for each input file. Mark compile unit create for main_input_filename as "main" compile unit. Use appropriate compile unit, based on source location information collected from the tree node, while creating llvm.dbg.* values using DebugInfo APIs. --- This is Part 1. llvm-svn: 63400
