2009-08-13Fix a 4x slowdown in llc -asm-verbose caused by the use ofDan Gohman
WriteAsOperand in more places. Now that more things are using WriteAsOperand, its behavior of constructing a TypePrinting object and populating it with strings for all the numbered types in the Module on each call is a significant bottleneck. Fancier solutions could be pursued here, but for now, just bypass the TypePrinting overhead in obvious cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78906 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-13Change the indentation for LLVM Assembly files from 1 tab to 2 spaces.Dan Gohman
This is vaguely consistent with LLVM's own source code, but more importantly it lets more lines stay within 80 columns. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78879 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-12Now that numbered types have their number printed, it's no longerDan Gohman
interesting to print the number in a comment. Numbered instructions don't need their number in a comment either. Also, tidy up newline printing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78865 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-12Extend the AsmWriter to print unnamed numbered types as "%0 = type ..."Dan Gohman
and unnamed numbered global variables as "@0 = global ...". Extend the AsmParser to recognize these forms. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78859 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-12Make AsmWriter more careful with formatted_raw_ostream so thatDan Gohman
it doesn't leave the underlying stream in unbuffered mode when the stream was originally buffered. Also, change WriteAsOperand back to plain raw_ostream. This lets it work for either formatted_raw_ostream or plain raw_ostream, so that it doesn't have to force a buffer flush on a plain raw_ostream. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78837 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-22Rename the new unsigned and signed keywords to nuw and nsw,Dan Gohman
which stand for no-unsigned-wrap and no-signed-wrap. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76810 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-20Add plumbing for the `linker_private' linkage type. This type is meant forBill Wendling
"private" symbols which the assember shouldn't strip, but which the linker may remove after evaluation. This is mostly useful for Objective-C metadata. This is plumbing, so we don't have a use of it yet. More to come, etc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76385 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-14llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable.Torok Edwin
This adds location info for all llvm_unreachable calls (which is a macro now) in !NDEBUG builds. In NDEBUG builds location info and the message is off (it only prints "UREACHABLE executed"). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75640 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-13Change printInstruction to not print a trailing newline. Value::dumpDan Gohman
always adds a newline, so this fixes Value::dump printing an extra blank line. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75481 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-11assert(0) -> LLVM_UNREACHABLE.Torok Edwin
Make llvm_unreachable take an optional string, thus moving the cerr<< out of line. LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for NDEBUG builds. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75379 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-25Allow aliasee to be a GEP or bitcast instead of just a bitcast.Chris Lattner
The real fix for this whole mess is to require the operand of the alias to be a *GlobalValue* (not a general constant, including constant exprs) but allow the operand and the alias type to be unrelated. This fixes PR4066 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@70079 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-20Don't discard an AssemblyAnnotationWriter when writing GlobalValues,Dan Gohman
which include Functions, where it can be quite useful to use an AssemblyAnnotationWriter. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69598 91177308-0d34-0410-b5e6-96231b3b80d8

to support C99 inline, GNU extern inline, etc. Related bugzilla's include PR3517, PR3100, & PR2933. Nothing uses this yet, but it appears to work. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68940 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-04Add support for embedded metadata to LLVM. This introduces two new types ofNick Lewycky
Constant, MDString and MDNode which can only be used by globals with a name that starts with "llvm." or as arguments to a function with the same naming restriction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68420 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-23Fix internal representation of fp80 to be theDale Johannesen
same as a normal i80 {low64, high16} rather than its own {high64, low16}. A depressing number of places know about this; I think I got them all. Bitcode readers and writers convert back to the old form to avoid breaking compatibility. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@67562 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-13Second installment of "BasicBlock operands to the back"Gabor Greif
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66920 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-11Remove the one-definition-rule version of extern_weakDuncan Sands
linkage: this linkage type only applies to declarations, but ODR is only relevant to globals with definitions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66650 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-07Introduce new linkage types linkonce_odr, weak_odr, common_odrDuncan Sands
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66339 91177308-0d34-0410-b5e6-96231b3b80d8
