* Pretty-printing comments for literal floating point in .s files.Jim Grosbach2012-03-231-2/+6

* In erroneous inline assembly we could mistakenly try to access theEric Christopher2012-03-221-1/+5
| | | | | | | | | metadata operand as an actual operand, leading to an assert. Error out in this case. rdar://11007633 llvm-svn: 153234
* It's possible to have a constant expression who's size is quite big (e.g.,Bill Wendling2012-03-201-11/+17
| | | | | | | | | | | | | | i128). In that case, we may not be able to print out the MCExpr as an expression. For instance, we could have an MCExpr like this: 0xBEEF0000BEEF0000 | (0xBEEF0000BEEF0000 << 64) The MCExpr printer handles sizes up to 64-bits, but this expression would require 128-bits. In this situation, try to evaluate the constant expression and emit that as the value into 64-bit chunks. <rdar://problem/11070338> llvm-svn: 153081

* Revert "Reorder the sections being output to reduce the number of assembler"Eric Christopher2012-03-021-3/+3
| | | | | | | | | The inline table needs to be constructed ahead of time so that it doesn't try to create new strings while we're emitting everything. This reverts commit a8ff9bccb399183cdd5f1c3cec2bda763664b4b0. llvm-svn: 151864
* Reorder the sections being output to reduce the number of assemblerEric Christopher2012-03-011-3/+3
| | | | | | | | | fixups that are being used to determine section offsets. Reduces the total number of fixups by 50% for a non-trivial testcase. Part of rdar://10413936 llvm-svn: 151852
* Minimal changes for LLVM to compile under VS11.Michael J. Spencer2012-03-011-1/+1
| | | | llvm-svn: 151849
* Allow the use of an alternate symbol for calculating a function's size.Hal Finkel2012-02-221-1/+4
| | | | | | | | | | | | | The standard function epilog includes a .size directive, but ppc64 uses an alternate local symbol to tag the actual start of each function. Until recently, binutils accepted the .size directive as: .size test1, .Ltmp0-test1 however, using this directive with recent binutils will result in the error: .size expression for XXX does not evaluate to a constant so we must use the label which actually tags the start of the function. llvm-svn: 151200
* Only add DW_AT_prototyped if we're working with a C-like language.Eric Christopher2012-02-221-3/+12

* Modify the code that emits the module flags to use the new module flags accessorBill Wendling2012-02-151-2/+4
| | | | | | | | | method. This allows the target lowering code to not have to deal with MDNodes. Also, avoid leaking memory like a sieve by not creating a global variable for the image info section, but just emitting the code directly. llvm-svn: 150624
* Add code to the target lowering object file module to handle module flags.Bill Wendling2012-02-141-0/+4
| | | | | | | | The MachO back-end needs to emit the garbage collection flags specified in the module flags. This is a WIP, so the front-end hasn't been modified to emit these flags just yet. Documentation and front-end switching to occur soon. llvm-svn: 150507

* reapply the patches reverted in r149470 that reenable ConstantDataArray,Chris Lattner2012-02-051-23/+10
| | | | | | | | | but with a critical fix to the SelectionDAG code that optimizes copies from strings into immediate stores: the previous code was stopping reading string data at the first nul. Address this by adding a new argument to llvm::getConstantStringInfo, preserving the behavior before the patch. llvm-svn: 149800
* Emit new property tag.Devang Patel2012-02-041-1/+29
| | | | llvm-svn: 149737

* Chris's constant data sequence refactoring actually enabled printingChandler Carruth2012-01-301-1/+1
| | | | | | | | | | | | | | | | vectors of all one bits to be printed more cleverly in the AsmPrinter. Unfortunately, the byte value for all one bits is the same with -fsigned-char as the error return of '-1'. Force this to be the unsigned byte value when returning it to avoid this problem, and update the test case for the shiny new behavior. Yay for building LLVM and Clang with -funsigned-char. Chris, please review, and let me know if there is any reason to not desire this change. It seems good on the surface, and certainly intended based on the code written. llvm-svn: 149299

| | | | | | | | relocations applied to all C++ constructors and destructors. This enables the linker to match concrete relocation types (absolute or relative) with whatever library or C++ support code is being linked against. llvm-svn: 149057
* Properly emit ctors / dtors with priorities into desired sectionsAnton Korobeynikov2012-01-251-22/+17

* An option to selectively enable part of ARM EHABI support.Evgeniy Stepanov2012-01-241-5/+14
| | | | | | | | This change adds an new option --arm-enable-ehabi-descriptors that enables emitting unwinding descriptors. This provides a mode with a working backtrace() without the (currently broken) exception support. llvm-svn: 148800
* Bit pack DIE structures better.Benjamin Kramer2012-01-241-23/+23
| | | | | | 16 bits are sufficient to store attributes, tags and forms. llvm-svn: 148799
* Remove generation of DW_AT_sibling. Nothing as far as I can tell uses it.Eric Christopher2012-01-243-26/+0
| | | | | | | | Saves about 1.5% on debug info size. rdar://10278198 llvm-svn: 148794
* Add AsmPrinter (aka MCLowering) support for ConstantDataSequential, Chris Lattner2012-01-241-32/+91
| | | | | | | | and clean up some other misc stuff. Unlike ConstantArray, we will prefer to emit .fill directives for "String" arrays that all have the same value, since they are denser than emitting a .ascii llvm-svn: 148793
* Revert r148686 (and r148694, a fix to it) due to a serious layeringChandler Carruth2012-01-241-20/+5
| | | | | | | | | | | | | | | | | | violation -- MC cannot depend on CodeGen. Specifically, the MCTargetDesc component of each target is actually a subcomponent of the MC library. As such, it cannot depend on the target-independent code generator, because MC itself cannot depend on the target-independent code generator. This change moved a flag from the ARM MCTargetDesc file ARMMCAsmInfo.cpp to the CodeGen layer in ARMException.cpp, leaving behind an 'extern' to refer back to it. That layering order isn't viable givin the constraints outlined above. Commandline flags are designed to be static specifically to avoid these types of bugs. Fixing this is likely going to require some non-trivial refactoring. llvm-svn: 148759
