| | | | | | | | This is the CodeGen equivalent of r153747. I tested that there is not noticeable performance difference with any combination of -O0/-O2 /-g when compiling gcc as a single compilation unit. llvm-svn: 153817

* Revert r124611 - "Keep track of incoming argument's location while emitting ↵Devang Patel2011-02-211-3/+1
| | | | | | | | | | | LiveIns." In other words, do not keep track of argument's location. The debugger (gdb) is not prepared to see line table entries for arguments. For the debugger, "second" line table entry marks beginning of function body. This requires some coordination with debugger to get this working. - The debugger needs to be aware of prolog_end attribute attached with line table entries. - The compiler needs to accurately mark prolog_end in line table entries (at -O0 and at -O1+) llvm-svn: 126155

* Introducing the "linker_weak" linkage type. This will be used for Objective-CBill Wendling2010-06-291-6/+7
| | | | | | | | | | | | | | | | | | | metadata types which should be marked as "weak", but which the linker will remove upon final linkage. For example, the "objc_msgSend_fixup_alloc" symbol is defined like this: .globl l_objc_msgSend_fixup_alloc .weak_definition l_objc_msgSend_fixup_alloc .section __DATA, __objc_msgrefs, coalesced .align 3 l_objc_msgSend_fixup_alloc: .quad _objc_msgSend_fixup .quad L_OBJC_METH_VAR_NAME_1 This is different from the "linker_private" linkage type, because it can't have the metadata defined with ".weak_definition". llvm-svn: 107205

Apparently the buildbots were wrong about failures. --- Add some switches helpful for debugging: -print-before=<Pass Name> Dump IR before running pass <Pass Name>. -print-before-all Dump IR before running each pass. -print-after-all Dump IR after running each pass. These are helpful when tracking down a miscompilation. It is easy to get IR dumps and do diffs on them, etc. To make this work well, add a new getPrinterPass API to Pass so that each kind of pass (ModulePass, FunctionPass, etc.) can create a Pass suitable for dumping out the kind of object the Pass works on. llvm-svn: 100249
* Switch the code generator (except the JIT) onto the new DebugLocChris Lattner2010-04-021-9/+0
| | | | | | | | | | | | | | | representation. This eliminates the 'DILocation' MDNodes for file/line/col tuples from -O0 -g codegen. This remove the old DebugLoc class, making it a typedef for DebugLoc, I'll rename NewDebugLoc next. I didn't update the JIT to use the new apis, so it will continue to work, but be as slow as before. Someone should eventually do this or, better yet, rip out the JIT debug info stuff and build the JIT on top of MC. llvm-svn: 100209

* Stop trying to merge identical jump tables. This had been inadvertentlyBob Wilson2010-03-191-11/+0
| | | | | | | | | | | disabled for several months (since svn r88806) and no one noticed. My fix for pr6543 yesterday reenabled it, but broke the ARM port's code for using TBB/TBH. Rather than adding a target hook to disable merging for Thumb2 only, I'm just taking this out. It is not common to have identical jump tables, the code we used to merge them was O(N^2), and it only helps code size, not performance. llvm-svn: 98977

* Fix pr6543: svn r88806 changed MachineJumpTableInfo::getJumpTableIndex() toBob Wilson2010-03-181-3/+12
| | | | | | | | | | | | | | | | | always create a new jump table. The intention was to avoid merging jump tables in SelectionDAGBuilder, and to wait for the branch folding pass to merge tables. Unfortunately, the same getJumpTableIndex() method is also used to merge tables in branch folding, so as a result of this change branch tables are never merged. Worse, the branch folding code is expecting getJumpTableIndex to always return the index of an existing table, but with this change, it never does so. In at least some cases, e.g., pr6543, this creates references to non-existent tables. I've fixed the problem by adding a new createJumpTableIndex function, which will always create a new table, and I've changed getJumpTableIndex to only look at existing tables. llvm-svn: 98845
* rearrange MCContext ownership. Before LLVMTargetMachine created it Chris Lattner2010-03-131-2/+2
| | | | | | | | | | | and passing off ownership to AsmPrinter. Now MachineModuleInfo creates it and owns it by value. This allows us to use MCSymbols more consistently throughout the rest of the code generator, and simplifies a bit of code. This also allows MachineFunction to keep an MCContext reference handy, and cleans up the TargetRegistry interfaces for AsmPrinters. llvm-svn: 98450
