* Retrying r91337:Bill Wendling2010-01-161-0/+7
| | | | | | | | The CIE says that the LSDA point in the FDE section is an "sdata4". That's fine, but we need it to actually be 4-bytes in the FDE for some platforms. Allow individual platforms to decide for themselves. llvm-svn: 93616
* Fixed library dependencies between the X86 disassembler andSean Callanan2009-12-221-4/+0

* Fix setting and default setting of code model for jit. Do thisEric Christopher2009-12-211-11/+20
| | | | | | | | | | by allowing backends to override routines that will default the JIT and Static code generation to an appropriate code model for the architecture. Should fix PR 5773. llvm-svn: 91824
* Table-driven disassembler for the X86 architecture (16-, 32-, and 64-bit Sean Callanan2009-12-191-0/+4
| | | | | | | | | | | | | | | | | | | | incarnations), integrated into the MC framework. The disassembler is table-driven, using a custom TableGen backend to generate hierarchical tables optimized for fast decode. The disassembler consumes MemoryObjects and produces arrays of MCInsts, adhering to the abstract base class MCDisassembler (llvm/MC/MCDisassembler.h). The disassembler is documented in detail in - lib/Target/X86/Disassembler/X86Disassembler.cpp (disassembler runtime) - utils/TableGen/DisassemblerEmitter.cpp (table emitter) You can test the disassembler by running llvm-mc -disassemble for i386 or x86_64 targets. Please let me know if you encounter any problems with it. llvm-svn: 91749
* Factor the stack alignment calculations out into a target independent pass.Jim Grosbach2009-12-021-1/+1

* Make X86-64 in the Large model always emit 64-bit calls.Jeffrey Yasskin2009-11-161-14/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The large code model is documented at http://www.x86-64.org/documentation/abi.pdf and says that calls should assume their target doesn't live within the 32-bit pc-relative offset that fits in the call instruction. To do this, we turn off the global-address->target-global-address conversion in X86TargetLowering::LowerCall(). The first attempt at this broke the lazy JIT because it can separate the movabs(imm->reg) from the actual call instruction. The lazy JIT receives the address of the movabs as a relocation and needs to record the return address from the call; and then when that call happens, it needs to patch the movabs with the newly-compiled target. We could thread the call instruction into the relocation and record the movabs<->call mapping explicitly, but that seems to require at least as much new complication in the code generator as this change. To fix this, we make lazy functions _always_ go through a call stub. You'd think we'd only have to force lazy calls through a stub on difficult platforms, but that turns out to break indirect calls through a function pointer. The right fix for that is to distinguish between calls and address-of operations on uncompiled functions, but that's complex enough to leave for someone else to do. Another attempt at this defined a new CALL64i pseudo-instruction, which expanded to a 2-instruction sequence in the assembly output and was special-cased in the X86CodeEmitter's emitInstruction() function. That broke indirect calls in the same way as above. This patch also removes a hack forcing Darwin to the small code model. Without far-call-stubs, the small code model requires things of the JITMemoryManager that the DefaultJITMemoryManager can't provide. Thanks to echristo for lots of testing! llvm-svn: 88984

* llvm-mc/X86: Implement single instruction encoding interface for MC.Daniel Dunbar2009-08-271-0/+4
| | | | | | | | | | | | - Note, this is a gigantic hack, with the sole purpose of unblocking further work on the assembler (its also possible to test the mathcer more completely now). - Despite being a hack, its actually good enough to work over all of 403.gcc (although some encodings are probably incorrect). This is a testament to the beauty of X86's MachineInstr, no doubt! ;) llvm-svn: 80234

* Rip all of the global variable lowering logic out of TargetAsmInfo. SinceChris Lattner2009-07-281-14/+12
| | | | | | | | | | | | | | | | | | | | it is highly specific to the object file that will be generated in the end, this introduces a new TargetLoweringObjectFile interface that is implemented for each of ELF/MachO/COFF/Alpha/PIC16 and XCore. Though still is still a brutal and ugly refactoring, this is a major step towards goodness. This patch also: 1. fixes a bunch of dangling pointer problems in the PIC16 backend. 2. disables the TargetLowering copy ctor which PIC16 was accidentally using. 3. gets us closer to xcore having its own crazy target section flags and pic16 not having to shadow sections with its own objects. 4. fixes wierdness where ELF targets would set CStringSection but not CStringSection_. Factor the code better. 5. fixes some bugs in string lowering on ELF targets. llvm-svn: 77294

* Reimplement rip-relative addressing in the X86-64 backend. The newChris Lattner2009-06-271-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implementation primarily differs from the former in that the asmprinter doesn't make a zillion decisions about whether or not something will be RIP relative or not. Instead, those decisions are made by isel lowering and propagated through to the asm printer. To achieve this, we: 1. Represent RIP relative addresses by setting the base of the X86 addr mode to X86::RIP. 2. When ISel Lowering decides that it is safe to use RIP, it lowers to X86ISD::WrapperRIP. When it is unsafe to use RIP, it lowers to X86ISD::Wrapper as before. 3. This removes isRIPRel from X86ISelAddressMode, representing it with a basereg of RIP instead. 4. The addressing mode matching logic in isel is greatly simplified. 5. The asmprinter is greatly simplified, notably the "NotRIPRel" predicate passed through various printoperand routines is gone now. 6. The various symbol printing routines in asmprinter now no longer infer when to emit (%rip), they just print the symbol. I think this is a big improvement over the previous situation. It does have two small caveats though: 1. I implemented a horrible "no-rip" modifier for the inline asm "P" constraint modifier. This is a short term hack, there is a much better, but more involved, solution. 2. I had to xfail an -aggressive-remat testcase because it isn't handling the use of RIP in the constant-pool reading instruction. This specific test is easy to fix without -aggressive-remat, which I intend to do next. llvm-svn: 74372

* Second attempt:Bill Wendling2009-04-291-12/+15
| | | | | | | | | | | | Massive check in. This changes the "-fast" flag to "-O#" in llc. If you want to use the old behavior, the flag is -O0. This change allows for finer-grained control over which optimizations are run at different -O levels. Most of this work was pretty mechanical. The majority of the fixes came from verifying that a "fast" variable wasn't used anymore. The JIT still uses a "Fast" flag. I'll change the JIT with a follow-up patch. llvm-svn: 70343
