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
2009-07-14Reapply my previous asmprinter changes now with more testing and two Chris Lattner
additional bug fixes: 1. The bug that everyone hit was a problem in the asmprinter where it would remove $stub but keep the L prefix on a name when emitting the indirect symbol. This is easy to fix by keeping the name of the stub and the name of the symbol in a StringMap instead of just keeping a StringSet and trying to reconstruct it late. 2. There was a problem printing the personality function. The current logic to print out the personality function from the DWARF information is a bit of a cesspool right now that duplicates a bunch of other logic in the asm printer. The short version of it is that it depends on emitting both the L and _ prefix for symbols (at least on darwin) and until I can untangle it, it is best to switch the mangler back to emitting both prefixes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75646 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

2009-07-13Begin the painful process of tearing apart the rat'ss nest that is ↵Owen Anderson
Constants.cpp and ConstantFold.cpp. This involves temporarily hard wiring some parts to use the global context.

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

2009-05-09Rename PaddedSize to AllocSize, in the hope that thisDuncan Sands
will make it more obvious what it represents, and stop it being confused with the StoreSize. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@71349 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-11It makes no sense to have a ODR version of commonDuncan Sands
linkage, so remove it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66690 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
2009-02-18Add support to the JIT for true non-lazy operation. When a call to a functionNate Begeman
that has not been JIT'd yet, the callee is put on a list of pending functions to JIT. The call is directed through a stub, which is updated with the address of the function after it has been JIT'd. A new interface for allocating and updating empty stubs is provided. Add support for removing the ModuleProvider the JIT was created with, which would otherwise invalidate the JIT's PassManager, which is initialized with the ModuleProvider's Module. Add support under a new ExecutionEngine flag for emitting the infomration necessary to update Function and GlobalVariable stubs after JITing them, by recording the address of the stub and the name of the GlobalValue. This allows code to be copied from one address space to another, where libraries may live at different virtual addresses, and have the stubs updated with their new correct target addresses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@64906 91177308-0d34-0410-b5e6-96231b3b80d8

2008-05-14Add CommonLinkage; currently tentative definitionsDale Johannesen
are represented as "weak", but there are subtle differences in some cases on Darwin, so we need both. The intent is that "common" will behave identically to "weak" unless somebody changes their target to do something else. No functional change as yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51118 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-16Correlate stubs with functions in JIT: when emitting a stub, the JIT tells ↵Nicolas Geoffray

2008-03-11Use PassManagerBase instead of FunctionPassManager for functionsDan Gohman
that merely add passes. This allows them to be used with either FunctionPassManager or PassManager, or even with a custom new kind of pass manager. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48256 91177308-0d34-0410-b5e6-96231b3b80d8

2008-01-29Use getPreferredAlignmentLog or getPreferredAlignmentDuncan Sands
to get the alignment of global variables, rather than using hand-made versions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46495 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-29Remove attribution from file headers, per discussion on llvmdev.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45418 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-05Eliminate the remaining uses of getTypeSize. ThisDuncan Sands
should only effect x86 when using long double. Now 12/16 bytes are output for long double globals (the exact amount depends on the alignment). This brings globals in line with the rest of LLVM: the space reserved for an object is now always the ABI size. One tricky point is that only 10 bytes should be output for long double if it is a field in a packed struct, which is the reason for the additional argument to EmitGlobalConstant. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43688 91177308-0d34-0410-b5e6-96231b3b80d8

2007-09-11Add APInt interfaces to APFloat (allows directlyDale Johannesen
access to bits). Use them in place of float and double interfaces where appropriate. First bits of x86 long double constants handling (untested, probably does not work). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41858 91177308-0d34-0410-b5e6-96231b3b80d8
2007-09-06Next round of APFloat changes.Dale Johannesen
Use APFloat in UpgradeParser and AsmParser. Change all references to ConstantFP to use the APFloat interface rather than double. Remove the ConstantFP double interfaces. Use APFloat functions for constant folding arithmetic and comparisons. (There are still way too many places APFloat is just a wrapper around host float/double, but we're getting there.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41747 91177308-0d34-0410-b5e6-96231b3b80d8
