2009-11-04Array element size does not match array size but array is not a bitfield. Devang Patel
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@86043 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-04Print out an informative comment for KILL instructions.Jakob Stoklund Olesen
The KILL pseudo-instruction may survive to the asm printer pass, just like the IMPLICIT_DEF. Print the KILL as a comment instead of just leaving a blank line in the output. With -asm-verbose=0, a blank line is printed, like IMPLICIT?DEF. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@86041 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-25Remove VISIBILITY_HIDDEN from class/struct found inside anonymous namespaces.Nick Lewycky
Chris claims we should never have visibility_hidden inside any .cpp file but that's still not true even after this commit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85042 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-09Extract scope information from the variable itself, instead of relying on ↵Devang Patel
alloca or llvm.dbg.declare location. While recording beginning of a function, use scope info from the first location entry instead of just relying on first location entry itself. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83684 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-06Instead of printing unnecessary basic block labels as labels inDan Gohman
verbose-asm mode, print comments instead. This eliminates a non-comment difference between verbose-asm mode and non-verbose-asm mode. Also, factor out the relevant code out of all the targets and into target-independent code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83392 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-06Update processDebugLoc() so that it can be used to process debug info before ↵Devang Patel

2009-10-05strength reduce a ton of type equality tests to check the typeid (ThroughChris Lattner
the new predicates I added) instead of going through a context and doing a pointer comparison. Besides being cheaper, this allows a smart compiler to turn the if sequence into a switch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83297 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-30Add a new virtual EmitStartOfAsmFile method to the AsmPrinter and use thisBob Wilson
to emit target-specific things at the beginning of the asm output. This fixes a problem for PPC, where the text sections are not being kept together as expected. The base class doInitialization code calls DW->BeginModule() which emits a bunch of DWARF section directives. The PPC doInitialization code then emits all the TEXT section directives, with the intention that they will be kept together. But as I understand it, the Darwin assembler treats the default TEXT section as a special case and moves it to the beginning of the file, which means that all those DWARF sections are in the middle of the text. With this change, the EmitStartOfAsmFile hook is called before the DWARF section directives are emitted, so that all the PPC text section directives come out right at the beginning of the file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83176 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-30Add a way for a frontend to generate more complex dwarf locationMike Stump
information. This allows arbitrary code involving DW_OP_plus_uconst and DW_OP_deref. The scheme allows for easy extention to include, any, or all of the DW_OP_ opcodes. I thought about just exposing all of them, but, wasn't sure if people wanted the dwarf opcodes exposed in the api. Is that a layering violation? With this scheme, the entire existing block scheme used by llvm-gcc can be switched over to the new scheme. I think that would be cleaner, as then the compiler specific bits are not present in llvm proper. Before the old code can be yanked however, similar code in clang would have to be removed. Next up, more testing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83120 91177308-0d34-0410-b5e6-96231b3b80d8
