2014-01-03Make the llvm mangler depend only on DataLayout.Rafael Espindola
Before this patch any program that wanted to know the final symbol name of a GlobalValue had to link with Target. This patch implements a compromise solution where the mangler uses DataLayout. This way, any tool that already links with Target (llc, clang) gets the exact behavior as before and new IR files can be mangled without linking with Target. With this patch the mangler is constructed with just a DataLayout and DataLayout is extended to include the information the Mangler needs. llvm-svn: 198438
2013-12-05Remove the isImplicitlyPrivate argument of getNameWithPrefix.Rafael Espindola
getSymbolWithGlobalValueBase use is to create a name of a new symbol based on the name of an existing GV. Assert that and then remove the last call to pass true to isImplicitlyPrivate. This gives the mangler API a 1:1 mapping from GV to names, which is what we need to drop the mangler dependency on the target (and use an extended datalayout instead). llvm-svn: 196472
2013-12-02Move getSymbolWithGlobalValueBase to TargetLoweringObjectFile.Rafael Espindola
This allows it to be used in TargetLoweringObjectFileImpl.cpp. llvm-svn: 196117
2013-10-29Move getSymbol to TargetLoweringObjectFile.Rafael Espindola
This allows constructing a Mangler with just a TargetMachine. llvm-svn: 193630
2013-07-02[DebugInfo] Allow getDebugThreadLocalSymbol to return MCExprUlrich Weigand
This allows getDebugThreadLocalSymbol to return a generic MCExpr instead of just a MCSymbolRefExpr. This is in preparation for supporting debug info for TLS variables on PowerPC, where we need to describe the variable location using a more complex expression than just MCSymbolRefExpr. llvm-svn: 185460
2013-06-28DebugInfo: PR14728: TLS supportDavid Blaikie
Based on GCC's output for TLS variables (OP_constNu, x@dtpoff, OP_lo_user), this implements debug info support for TLS in ELF. Verified that this output is correct/sufficient on Linux (using gold - if you're using binutils-ld, you'll need something with the fix for http://sourceware.org/bugzilla/show_bug.cgi?id=15685 in it). Support on non-ELF is sort of "arbitrary" at the moment - if Apple folks want to discuss (or just go ahead & implement) how this should work in MachO, etc, I'm open. llvm-svn: 185203
2013-01-02Move all of the header files which are involved in modelling the LLVM IRChandler Carruth
into their new header subdirectory: include/llvm/IR. This matches the directory structure of lib, and begins to correct a long standing point of file layout clutter in LLVM. There are still more header files to move here, but I wanted to handle them in separate commits to make tracking what files make sense at each layer easier. The only really questionable files here are the target intrinsic tablegen files. But that's a battle I'd rather not fight today. I've updated both CMake and Makefile build systems (I think, and my tests think, but I may have missed something). I've also re-sorted the includes throughout the project. I'll be committing updates to Clang, DragonEgg, and Polly momentarily. llvm-svn: 171366
2012-12-03Use the new script to sort the includes of every file under lib.Chandler Carruth
Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] llvm-svn: 169131

llvm-svn: 148805
2012-01-10Add 'llvm_unreachable' to passify GCC's understanding of the constraintsChandler Carruth
of several newly un-defaulted switches. This also helps optimizers (including LLVM's) recognize that every case is covered, and we should assume as much. llvm-svn: 147861
2012-01-10Remove unnecessary default cases in switches that cover all enum values.David Blaikie
llvm-svn: 147855
2011-12-02Move global variables in TargetMachine into new TargetOptions class. As an APINick Lewycky
change, now you need a TargetOptions object to create a TargetMachine. Clang patch to follow. One small functionality change in PTX. PTX had commented out the machine verifier parts in their copy of printAndVerify. That now calls the version in LLVMTargetMachine. Users of PTX who need verification disabled should rely on not passing the command-line flag to enable it. llvm-svn: 145714
2011-07-20Goodbye TargetAsmInfo. This eliminate last bit of CodeGen and Target in llvm-mc.Evan Cheng
There is still a bit more refactoring left to do in Targets. But we are now very close to fixing all the layering issues in MC. llvm-svn: 135611
2011-07-20Add MCObjectFileInfo and sink the MCSections initialization code fromEvan Cheng
TargetLoweringObjectFileImpl down to MCObjectFileInfo. TargetAsmInfo is done to one last method. It's *almost* gone! llvm-svn: 135569
2011-07-18land David Blaikie's patch to de-constify Type, with a few tweaks.Chris Lattner

llvm-svn: 135068
2011-06-23Use the presence of the __compact_unwind section to indicate that a targetBill Wendling
supports compact unwind info instead of having a separate flag indicating this. llvm-svn: 133685
2011-06-22Add a flag that indicates whether a target supports compact unwind info or not.Bill Wendling
llvm-svn: 133662
2011-06-22Add a __LD,__compact_unwind section.Bill Wendling
If the linker supports it, this will hold the CIE and FDE information in a compact format. The implementation of the compact unwinding emission is coming soon. llvm-svn: 133658
2011-06-19Fix a FIXME by making GlobalVariable::getInitializer() return aJay Foad
const Constant *. llvm-svn: 133400
2011-05-05Remove a flag that would set the ".eh" symbol as .globl. MachO was the only oneBill Wendling
who used this flag, and it now emits CFI and doesn't emit this anymore. All other targets left this flag "false". <rdar://problem/8486371> llvm-svn: 130918
2011-05-01GCC uses a different encoding of pointers in the FDE when usingRafael Espindola
-fno-dwarf2-cfi-asm. Implement the same behavior. llvm-svn: 130637
2011-04-27Remove unnecessary argument.Rafael Espindola
llvm-svn: 130343
2011-04-27Rename getPersonalityPICSymbol to getCFIPersonalitySymbol, document it, andRafael Espindola
give it a bit more responsibility. Also implement it for MachO. If hacked to use cfi, 32 bit MachO will produce .cfi_personality 155, L___gxx_personality_v0$non_lazy_ptr and 64 bit will produce .cfi_presonality ___gxx_personality_v0 The general idea is that .cfi_personality gets passed the final symbol. It is up to codegen to produce it if using indirect representation (like 32 bit MachO), but it is up to MC to decide which relocations to create. llvm-svn: 130341

2011-01-18minor change to rafael's recent patches: if something isChris Lattner
constant but requires a unique address, we can still put it in a readonly section, just not a mergable one. llvm-svn: 123711

2010-03-11rename getSymbolForDwarf* to getExprForDwarf* since it returnsChris Lattner
